This won’t really be a post about doing a lot of operating. It’s mostly about powering and recharging stuff. The long story short of operating from the specific site we were at is that I didn’t make any contacts apart from another station on JS8Call that heard one of my heartbeats. I wasn’t in a good position to be heard, but I could hear a lot of other stations on 40m throughout the afternoon and evening. I was also able to hear Radio Havana and what I suspect might have been Zambia NBC Radio 1 for a few minutes.
I was able to recharge the Bioenno 4.5Ah battery in an hour or so as we broke camp and packed the vehicle. I’d been using that radio the previous day and listening to shortwave stations the whole night. A solid hour of charging at 1.1A using the BuddiPole PowerMini on a single GoalZero Nomad 20 solar panel was enough to replentish the battery.
The 100Ah battery was easily charged in about 45 minutes. We’d only drawn about 3.5Ah from the battery running lights, charging a phone, and a portable projector. The panel in use here is a Bioenno 100W folding panel and from the VictronConnect application screenshot it’s charging at about 4.5A. The back view shows how the solar panel is connected to the charging unit and the battery. This is the first time I’ve used the West Mountain Radio Epic PWRGate to charge the 100Ah battery. I’m hoping to use it for charging from a vehicle alternator, an existing DC power supply, or solar panel. I’m also hoping to add a charger like this to the box along with a temperature probe to ensure the battery isn’t charged when it’s too hot or cold. The Relion RB100 has a minimum charging temperature of -4F.
This a detailed view of the West Mountain Radio Epic PWRGate. The green LED indicates it has good solar charging voltage, and the blue LED that was slowly pulsing which indicated that the battery was being bulk charged by the solar panel. The PWRGate is programmed with the specific battery chemistry settings for LiFePO4 batteries and is current limited at 6A for some of the other batteries I charge with this setup.
Hello all, it’s about time I wrote a post about my camping trip my partner and I took a couple weeks ago. I took my trusty Lab599 TX-500 kit, a couple 20W GoalZero Nomad solar panels, headset, and table/chair combo up camping with our “new” 4×4. I wanted to do some HF QRP and some handheld UHF/VHF operation while I was out. I brought some of the same portable furniture that I used at the beach last post since it worked out so well.
The view was pretty sweet for this one. The smoke from the wildfires made everything a bit more hazy but pretty great none-the-less.
While operating HF I made a number of contacts, and the solar panels kept the 4.5Ah Bioenno LiFePO4 battery built into the HF QRP radio kit charged the whole day. The first HF contact I made was with Stefan, AF6SA who was working POTA in Eldorado Natoinal Forest (K-4455). His signal was 5/6 on at about 450 miles away on 20m. I also made a contact with VA3AAA, Stanley in Ontario, Canada. I was pretty excited to reach Ontario with a low power radio. That contact was also logged on 20m. I also made a contact with the K0GQ radio club in MO on 20m. All of these contacts were made between 5 and 10w using the Trail-friendly EndFedz EFT-10/20/40 antenna strung between a couple trees about 50′ apart and about 25′ above the ground.
I switched radios and bands to see if I could get into some of the repeaters in the Portland area (I could) with my Yaesu FT3DR and a Signal Stick antenna. I ended up on 2m and caught two hams on 146.520Mhz doing a SOTA activation: K7AHR and K7IW. I think they were on Lookout Mountain, but I can’t remember and didn’t properly log it. I was running 5W for those contacts.
Howdy and welcome back! I spent the day at Rooster Rock, a clothing-optional beach on the banks of the Sandy River in Oregon. Since I burn easily I got a cheap tent from Target to get very sandy and to keep me and my gear safe from the sun! As a bonus this specific tent actually has a pass through for cables in the front corner to the left of the door which is pretty great for running solar panel connectors and feed line. I didn’t have any successful contacts, but that’s not surprising given the difficulties I had tuning the Superantenna. I couldn’t manage to get a decent SWR on the QRP radio. The real point of the post is about portable shelter options that can keep you out an entire day even when you’re literally naked. This was able to keep me and the gear cool enough to keep going. Folding a corner of the tent up allowed the interior mesh to breathe away from the sun. In the picture below you can see through the door that the rain fly has been lifted.
We weren’t able to get the best spot but at least we got something out of the way on a path and had enough space to set the tent up. I had enough clear space to keep the solar panels going all day as well. They kept the battery kept everything charged and running. I tried to see if I could make any UHF/VHF contacts but I was in a gorge so I had very limited luck. I’m sure you’re just as shocked as I am. I then tuned the Superantenna as best I could for 20m and tried to make some contacts but I wasn’t getting out. I heard a bunch of stations on the east coast and in the midwest including participating in a New England radio event or QSO party for the 4th of July weekend. I wasn’t able to get out to anyone though. In addition to those stations I could also hear but not reach Paolo IK5SRF in Tuscany, Italy. Paolo had quite the pileup going.
A view of the radio setup, the table, and chair. This three-legged chair is actually pretty comfortable.
My conspicuously-empty log book with only notes and the radio.
At the end of the day breaking the tent down was pretty easy. We were able to tear down the entire site and radio station in about an hour, have it loaded into the beach wagon and off we were. Much of that time was as usual rolling feed line so it’s not a pain to unroll later.
Hello all, while this isn’t actually a post about amateur radio I wanted to post about how we (my partner and I) decided to deal with the June 2021 heatwave in the Pacific Northwest. While this isn’t directly related to ham radio I think it’s worth discussing as the temperatures in this region don’t typically reach the levels they were at and most homes and people aren’t prepared to cope with those temperatures. Some folks will probably laugh at this post and the situation in its entirety, but you have to remember that homes, businesses, animals, and people in what is typically a fairly temperate climate aren’t used to these sorts of temperature spikes. Some of us will mostly be uncomfortable and maybe inconvenienced but for others this is a deadly situation. There are large numbers of unhoused folks sleeping rough and stuck outdoors during this time. It is easy to die of exposure in situations like this even in a city. In nature you might be better or worse off depending on where you are. When operating in the field it’s important to keep yourself and your equipment cool, and I don’t think this is the last time we will have unseasonably hot weather. Next time it could be during another disaster or trigger secondary problems like power outages. This post is mostly about optimizing a solution for a problem with cheap and easily available materials to decrease misery and help alleviate a situation that could lead to an emergency.
One obvious issue with the house we live in during this specific situation is that it has a very large single-paned south-facing window, which definitely heats the house up during the summer. We were fortunate enough to have a single window-mounted AC unit for the whole house but it was only able to keep the house in the high 80s to low 90s which is definitely better than 110+ degrees, but I wasn’t sure if the power grid would hold up under additional load and the heat itself. My partner and I decided we’d take some steps to cool the house further for our comfort and our dog’s safety. The most obvious thing we could do to limit solar gain would be to cover windows that we could with blankets, etc. which helped, but we didn’t have a big enough blanket to cover the window. I wanted to actually keep the heat outside rather than heating a blanket that was already on the inside of the house and having it radiate that heat into the living space. A cheap reflective shield with an air gap between the shield and the house would be a possible solution to the problem.
Problems to solve:
Keeping as much heat out of the house as possible
Shielding a large area
Keeping it simple
Passive cooling (a plus)
Not wanting to put tape on paint
Keeping it cheap
A quick trip to the grocery store yielded the following materials: a roll of duct tape, 50′ of paracord, and 4 mylar blankets (we only needed 3 it turns out). The entire solution cost less than $20, some moderate burns, and sweat. We taped the edges of the mylar blankets on both sides to hold them together and taped across the gap intentionally leaving holes that would be left to ensure the wind loading was lower since this was in part just held up by tape. Our first attempt at the solution was to run paracord from the fence to the gutter, but it required too much paracord and the angle the mylar blanket would be at would be less-than-optimal so I ran the paracord from the ground and weighed the ground ends and center point down with rocks. The end of the paracord attached to the gutter was run between the gutter nails and didn’t require tying or taping. I did, however, end up taping the corner of the mylar blanket to the inside of the rain gutter because there wasn’t a suitable anchor point for paracord near the corner of the house that I wanted to cover. We weighed down one corner with some rocks and were back inside within 35 minutes. Ouch note: ladders get hot in intense sun and gloves are a good idea.
The photos I’m including were taken after day 2. We had to go back out and shore parts of the heat shield up because some of the spots I taped to the paracord slid down. To combat that I just did extra-long wraps of duct tape around the paracord and attached it to the edges of the mylar blankets. I also taped the inside of the shield to the paracord at the bottom to prevent the heat shield from riding up the paracord. The end of the mylar blanket that was weighed down by rocks also tore in the wind/breeze so we coated the corner we stuck the rocks in with duct tape as a protective pad for the mylar. All the photos are this setup are shown below. The air gap between the window and mylar also served as a nice passive cooler. As the breeze and wind blew between the mylar and window it carried some of the heat away. After installing the mylar heat shield the temperature in the house dropped by 10-15 degrees over the next 30 minutes!
Cheap materials that are readily available
Relatively fast to set up on the fly
Minimal tooling required to put it up
No tape used where it could remove paint
Effective at reducing temperature and quickly
Will require cutting to get it down
Required some maintenance after a day of being up
Needs a ladder to set up
Required two people to be outside in the heat on the south face of the house for 35 minutes
Dealing with duct tape on top of a ladder in wind wearing gloves is a PITA
I burned myself on the ladder before getting gloves. Don’t get burned.
I got sunburned, but when I sweat it dissolves sunscreen so that was expected.
I should build something prettier ahead of time that’s easy to take up and down but also cheap to build.
Putting a ladder in the middle of a garden bed without absolutely destroying the (very thorny) plants is hard but doable.
The mylar blankets in this configuration worked very well!
Good news everyone! I finally made a long-distance contact running QRP (10w) on SSB. I was able to complete a QSO with N8II in Jefferson County, WV on 20m during a WV QSO party from the top of Mt. Tabor. The distance between our stations was about 2,290 miles. I had been attempting to contact the station all day on and off since about 16:30 Pacific time. I was able to reach a couple stations in the Portland, OR area and one of them suggested that my portable antenna might be hung too low (at about 20′) and doing NVIS instead of getting out so I re-hung both ends of the antenna an additional 6′ higher and tried again. I had attempted to enlist K7AJK’s help to test my station’s audio to see if I was having RF feedback, but it seems he was in one of my antenna’s nulls. The next set of attempts I was able to nearly complete a QSO with N8II, but failed to get my full call and location across. I hit pause on attempting contact for a few minutes to attempt some other frequencies and 40m. After coming back and making another attempt I was finally able to make the contact with a bit of difficulty, but there you have it!
As a side note I did some JS8Call work on 20m and 40m as well. The furthest signal report was about 2,000 miles away! Not bad for a portable QRP station.
A few extra feet of antenna elevation can make all the difference!
Minimal power can go a long way.
If you want to use a headset with a radio make sure you bring a PTT.
Two 20w solar panels did a good job of powering the entire setup until the sun got low enough that trees covered them. I barely used the battery in 5 hours of operation.
Don’t position your station under the feed line. It might cause RF feedback.
Bring extra water. I didn’t have enough for 5 hours.
Alright, so, all this actually happened on May 29th. I just haven’t been able to sit down a put a post together so here we go! My partner and I decided to take a trip out to Oakridge, OR to avoid the setup for camping but to at least see some sweet nature (nature is neat). Read this before following that link. Naturally I decided to take the opportunity to do some transmitting, and the setup at Salt Creek Falls was the only setup I documented so here it is. We started by following the trail down to the lower observation area at the falls which is pretty great. It was a hot day and the mist coming from the bottom of the falls was pretty refreshing. I climbed back up to the top of the path to make a sked, or, prearranged SSB contact with Kevin, K7AJK in Portland, OR. I also grabbed some water from a stream on the way up for my Sawyer straw.
It only took about 35 minutes to set the station up. Most of that was me failing like a complete amateur to get the paracord where I wanted it in two trees that were spaced about 80 feet apart using an arborist’s throw weight. For this contact we were going to attempt to do 80m NVIS so I strung my Chameleon EMCOMM III portable in a horizontal configuration, which is the configuration recommended by Chameleon for NVIS work. I have some bad pictures of both paracord runs attached to the antenna below, but because they’re bad so I’m not leading with them. What I didn’t capture in a photo was the fact there was a big hump between the trees and the antenna was only 6′ above the top of the hump between the trees, thus making the antenna not work as intended with the ground as a reflector. I still had a reasonably low SWR when transmitting on the Lab599 TX-500 but in retrospect I suspect the hump and poor atmospheric conditions might have resulted in difficulty getting out. I tuned to one of our prearranged frequencies and attempted to make contact once every 5 minutes for one hour. At two points I heard him calling but he didn’t get my replies. I’d later find out that a few of his calls were done at 100W and I could barely hear him. I’m not sure if this was due to bad space weather, poor antenna configuration, or both. I should have also been able to reach K7AJK as he was about 130 miles away which should be outside the NVIS skip zone (see Fig 3 here). It was a bummer but the bright spot is that I did manage to make some digital contacts using JS8Call despite not being able to reach K7AJK.
It’s hard to photograph thin wire antennas in trees from the ground.
Don’t forget to take pictures when you mess up.
Better antenna placement yields better results. I didn’t properly assess the height of the hump relative to where the antenna was hung or account for the antenna sagging in the middle near the top of the hump.
Sometimes the space weather doesn’t cooperate and you can’t account for it.
Take all sorts of pictures when operating, especially in an interesting environment. I did some drive-by VHF Winlink work going through Eugene, OR and also did some HF work and SWL on the beach at Crescent Lake as well. None of that includes my improvised sun shelter made from part of a shelter tent and some branches sawed off of dead trees near the beach shored up with rocks.
A notable plus is that the 20W GoalZero Nomad 20 solar panel is enough to keep the radio station up and running doing both phone and data work in good and intermittent sunlight. I typically get 1A out of the panel in decent sunlight. The 12Ah Bioenno battery was fully recharged within minutes of the QRP radio transmitting both at Salt Creek Falls and Crescent Lake.
Hello, long time and no post! Tonight I decided to test out an antenna a friend of mine, K7AJK, let me borrow which also enabled me to make my first attempt to work 6m! This antenna is a Par EndFedz 6m end-fed dipole, and it works on, you guessed it! The 6m (50-54MHz) band. This is my first attempt at working this band, and yet another attempt to make phone (voice) contacts with my Lab599 TX-500, a newer QRP rig which is capable of a maximum transmit power of 10W. With this antenna and band I decided to attempt to use single-sideband (SSB) for my phone contact as most of my digital communications and work use SSB. Since I’m working SSB instead of FM, the antenna should be oriented horizontally to ensure better signal propagation and better changes of making contact with other SSB stations. The kind of propagation I’m going for here is groundwave propagation, meaning I’m attempting to get my signal out over the ground to reach other stations rather than attempting to bounce it off the atmosphere as would be the case with other types of 6m propagation. To get the antenna up and off the ground away from the roof and gutters of the house I set my speaker stand antenna mast up with the “matchbox” end of the antenna connected to some guy wire eyelets on the dowel portion of the mast, and the other end attached to a post coming up from some raised garden beds. This got the antenna about 9-10′ off the ground and away from the gutters which is fine for a test run.
A good place to start when attempting to make contacts on a specific band is to choose that band’s calling frequency, or at least a region of the band that others using the mode you’ve chosen are likely to be. For 6m SSB the calling frequency is 50.125MHz, in the bottom half of the band. I use this handy chart by iCOM to keep track of what regions are used by operators, and to understand specific frequencies that have specific uses such as SSTV and calling frequencies. I parked on the 6m SSB calling frequency and called a few times with no answer. I enlisted the help of Kevin, K7AJK to see if he could use any antenna and tune his radio to the calling frequency. As I asked him to do that another station in Vancouver, WA that was about 10 miles away came in running 50W. As I began a QSO with the other station at 5W K7AJK’s station got the brunt of the power as it was nearby. Fortunately he had his attenuator on and even with a vertically polarized antenna it swamped the receiver. As that was happening I was able to drop power to 1W and then raise it to 2.5W. The station in WA was still able to read me at lower power levels, albeit I was scratchy. That bodes pretty well none the less. The radio also drew less than 1A at 5W of transmit power as measured with a Buddipole PowerMini that I hooked up. The radio drew about 0.13A receiving only.
After a bit of a posting hiatus I thought I’d post a bit about some impromptu radio operation from a park on a fairly sunny weekend day. My partner had a meeting with some folks in our pod in Ladd’s Addition, a Portland neighborhood with a central park so I decided to set up my portable radio station and do some UHF/VHF work locally to see who I could reach from said park. The station I brought is based on a Kenwood TM-V71A and fits in a single bag along with a battery and a 20W folding solar panel. This is essentially the same setup I’d use for emergency communications with a larger antenna or solar panel.
I ended up putting my modified Ed Fong DBJ-1 roll-up j-pole antenna in a large rose bush and hooking it up to my TM-V71A, and hooking the battery, solar panel, and charge controller up. I started operating at medium power (10W) and was able to reach Roger, W7RC, in Battleground, WA without issue on the 2M calling frequency (146.520MHz). This is pretty typical as he runs a beam antenna with the capability of transmitting at 1.5KW and is something of a local fixture. He reported me coming in with full quieting at 10W, and when I dropped to 5W (low power) he heard me with a little static. I also made some additional contacts including one in the Council Crest area: Ed, WB2QHS. He was out for a walk with an HT and we were able to talk with perfect clarity and then some static as he moved around with me running 5 and 10W. His elevated position helped facilitate communications. In about 2.5 hours I used somewhere around 1.3Ah of battery power, but was able to recharge the battery completely from the solar panel by the time I left. Not bad! The radio draws about 0.6A idling, and the solar panel charged at a maximum rate of ~1.1A in more intense sunlight. When I was transmitting at 10W the radio drew ~5A and at 5W ~3.5A. All these power figures are as measured by my Buddipole Power Mini. The current model features a USB port where the one I’m running doesn’t. I should also mention I topped up my phone charge from the battery as well.
If the solar panel provides more power than is required for the radio’s operation and the battery is charged the radio doesn’t draw from the battery. In the event the solar panel isn’t providing enough power to cover the radio’s power needs it dips into the battery, and when the radio consumes less power than the solar panel provides the battery is charged with spare current.
As shown above the whole station packs into my backpack without issue. Were I not on call for my job and carrying a hotspot and laptop there would be some additional room in the bag.
Hello all! It’s been a hot minute since I sat down and wrote about something! Today I’m writing about a car camping trip I took last weekend to Mt. Hood National Forest and some experiments with communications I did. Some of this is actually about cellular comms and some is about amateur radio fails. We spent the night at two spots – one at about 1,100 ft. and another around 3,500 ft. This becomes relevant mostly because of cell coverage, but also to some extent regarding stations I was able to receive doing SWL (shortwave listening).
The first night we spent I didn’t get a chance to set the portable HF radio up, but I did test my new WeBoost Reach Drive RV. I had no cell service with Verizon at that location and decided to mount the WeBoost high gain antenna on the the cargo basket. I then attached the small low gain antenna and connected the setup to my 40AH Bioenno LiFePO4 battery. After cycling my phone into and out of airplane mode I had 1X and enough service for voice calls. I did a couple tests and was able to reach a couple people via telephone as a test. Not bad! The cell booster drew approximately 1A at 14v using the DC hardwire power supply which I fitted with Anderson PowerPole connectors in a “right hand red” configuration to match my off grid power setup.
We found the second spot much earlier and had some daylight to set up. This spot was much higher in altitude than the first spot and was much colder. The weather was pretty rainy so we erected a shelter using a synthetic tarp, tarp poles, and some paracord that we keep around just for such an occasion. I intended to do some HF radio work but I couldn’t tune my hybrid Superantenna / Chameleon Mil Whip 2.0 setup to save my life so instead I figured I’d do some SWL later at night. In the mean time I decided to test the WeBoost again since the setup was fairly easy. I set it up again and cycled my phone into and out of airplane mode. I was getting a 3G signal at first with occasional bursts of 4G before I fired the system up, and after it was all said and done I had fairly solid 4G service with a decent speed test of 7Mbps. Even though I wasn’t able to tune my antenna on 20 or 40m I was able to do some excellent shortwave listening with the Lab599 TX-500. I was able to get the BBC World Service shortwave broadcast discussing the current COVID-19 situation in India on 6005KHz out of Ascension Island. I heard another station broadcasting in Arabic and playing music that I couldn’t find in listings. Both stations had some QSB, but the station in Arabic was significantly more faint with more significant QSB (irregular signal fading that occurs as a signal reflects off of the ionosphere). I suspect the higher elevation I was at helped me get stations much further away than I’d normally be able to in the metro Portland area. I’ve been able to pick up Radio Havana, Radio New Zealand Int’l, occasional Japanese stations, and lots of Chinese stations (if I’m up at 4 AM) in Portland. A good resource for finding shortwave stations is https://short-wave.info. I’ve also been able to reliably pick up a Russian numbers station designated M12 as well which broadcasts from Khabarovsk Russia.
So, we decided to go car camping this weekend and naturally I decided I’d bring my QRP rig and HT (handheld transceiver). The goal was to sleep in the back of our car and cook using a propane camp stove while not paying for a camping spot. I also wanted to see how well my QRP setup worked with fewer resources including charging and little space to store the setup and supporting equipment. For this I picked my Superantenna/Chameleon Mil Whip 2.0 kit and Lab599 TX-500 kit. Neither kit includes feed line. Keep that in mind while reading…
On a Friday after work we packed the car and left. A couple hours later we made it to our spot on the Oregon coast with some decent moonlight between spurts of rain. We made dinner in a fairly heavy wind out of the back of the car. We could hear the relaxing sound of crashing waves against rocks that we could barely see. After having some dinner we set up the folding mattress in the car and settled in for the night.
After waking up and getting ready we made some breakfast and coffee on a nearby park table. We had to wait till the rain stopped to make food but I was able to make some coffee in the rain without issue. I was half way through my coffee and food when I realized I didn’t pack any feed line! Fortunately we were close to a town that happened to have a store open that morning which had a box of left over parts labeled “CB Radio Parts”. There was a small RG-58 coax cable with PL-239 ends and thus my problem was solved! I purchased the cable and got underway for our hike.
We did a short hike and as we neared the end of the hike we found a small but well worn trail leading off the main path, so we took it in search of a spot where my partner could water color and I could set up and operate. Not too far down the offshoot trail we found a fairly open patch of moss with a fallen tree that I could use as a bench. I set up the Superantenna using the ground spike for simultaneous HF and 2m operation using the Superantenna MC2 and MP1C, topping the loading coils with my Chameleon Mil Whip 2.0 for increased SWR bandwidth over the titanium whip that comes with the Superantenna kit. Unfortunately the photo I took of the deployed antenna was corrupted by the time I got to uploading it. The UHF/VHF side of the Comet CF-706 duplexer was connected to my Yaesu FT3D so I could attempt contacts on the 2m calling frequency (146.520Mhz) and monitor/send 2m APRS packets.
I tuned the antenna using my NanoVNA for 20m and started working SSB phone. I attempted to respond to a number of calls and tried calling to no avail. After 40 minutes of trying between 5 and 8.5W I decided to switch to JS8Call. I have yet to make a phone contact on my Lab599 TX-500 on any band. I’m hoping I can just chalk this up to being run over by higher power stations. As I was setting my station up for digital comms I noticed something unexpected – the maidenhead coordinates in JS8Call hadn’t been updated automatically as js8cli would normally do, and I also noticed the time on the Pi varied by a minute from my cellphone. That’s highly unusual as the GPS unit typically corrects any RTC drift that might occur. The next step was to check my GPS unit’s LED through the vent holes in the case. It’s flashing one second on, and one off. For the specific Adafruit Ultimate GPS board I run that means the GPS hasn’t acquired a lock. I waited a few more minutes and found that it still hadn’t acquired a lock and decided to check the board for any broken or loose connections. Since the entire setup allows me to disassemble it without tools I did to inspect it. I found no loose connections or other apparent issues. It was time to reboot by fully removing power as had worked sometimes in the past. Still no luck following a full power down / power up sequence! I then leveraged my phone and tablet GPS units to get a position. My phone eventually got a location and grid square using the HamGPS application, but my phone had been on and tracking satellites for the entire hike. My Pi and tablet had been off. This is interesting because I had an OK view of the sky despite the very tall trees surrounding the patch. I hoped my GPS unit wasn’t damaged or malfunctioning and decided to manually set my JS8Call location from my phone, automatically acquire a timing offset from other stations in JS8Call and move on. I had a couple stations hear my heartbeats but couldn’t make contact with any operators directly. I also attempted to send an SMS message to a friend but alas no one was hearing my transmissions as the band seemed to have closed. Overall not the best luck, but it was time to head back to the trail head so we had daylight to drive out and make camp.
I decided to hook the gear up in the back of the car as my partner got the dog ready to head out in order to determine if my GPS unit was actually broken. I hooked everything up to the big battery that was in the trunk and after a minute or so the GPS lock LED flashed once every several seconds. This indicated a lock, so I fired the tablet up, logged into the Pi, and checked the reports with cgps, a test GPS client provided by the gpsd-clients package. They lined up with where we were. Even though I could see sky clearly through gaps in the canopy the GPS unit wasn’t able to acquire satellites in the time we spent in the clearing.
After arriving at camp and rigging the car for sleeping I set the radio up for shortwave listening and got my Yaesu FT3D connected to the duplexer after this photo was taken. It was a windy and chilly but great day. It was time for a beverage and some relaxing SWL and taking in the scenery before turning in for the night. I used the same setup as I did on the hike, except with a tripod for the antenna and no radials since I was receiving only. We were able to hear a number of stations, but settled on Radio Havana English (6.0MHz if I recall correctly) since they were playing music instead of the typical religious content with creepy-sounding voices you typically hear on US shortwave stations like WRMI in this part of the US.
Lessons learned: – Don’t forget your feed line. I got lucky enough that I could acquire some, but if this was a disaster or if I were on a hike/camping in a remote location I would have been unable to operate. – Even though you can see a lot of sky in an area, it doesn’t mean your GPS can acquire satellites. Be prepared with some mechanism to acquire and set your location and time for something like JS8Call. – When documenting something take a couple pictures in case one of them gets corrupted.
