EmComm II – KK4Z

FTX Fort Mountain State Park

This weekend I decided to camp at one of my favorite parks. Ft Mountain State Park. I go back a long way with this park. Thirty three years ago I spent a wonderful honeymoon there with my bride and princess. We recently spent a weekend there in the same cabin we spent our honeymoon in. Memories.

This time it’s a solo trip. I came up here for some radio adventure and I got it. On this trip, I did more EmComm related stuff. This was more like an FTX (field training exercise) than a simple POTA activation. I grabbed my normal gear and set myself some tasks to accomplish while out. I wanted to stretch my gear and me, do a grab and go like it would happen in a real scenario. I did not do any extra prep than I normally would do for a POTA activation.

My first task was to receive the National Intelligence Brief (NIB) from the Early Warning Network. I am the Communications Director (G6) of the Early Warning Amateur Radio Network (EWARN). We are building the EWARN system to best suit the needs of the Early Warning Network. This network collects information, analyzes it, and then disseminates the intelligence in products like the NIB.

Right now l receive the NIB via email and one of our projects is to be able to send the NIB to me and others via radio. We are looking at options to include using operators from AmRRon which we are developing a relationship with. AmRRon has some very talented operators. Getting back to my task, I received the NIB via my cell phone while on my way to the park. I pulled over in a gas station, connected my computer to my cell phone via the hotspot and downloaded the NIB onto my laptop.

I got the NIB ready to send over the radio. This includes formatting the document and then signing it using a PGP key. By signing the document this way, anyone with the public key can verify that the document was not altered. The document is not encrypted so it can be sent over the air. The next step is hooking up the laptop to the HF radio in my truck and sending the message. I decided to move since I didn’t think transmitting with a radio near gas pumps was a good idea so I moved. I found a pullover near the bottom of the mountain, on a road that leads up to the State Park. The radio wan an IC-7100 hooked up to ab AH-730 and a 102” whip.

Issue. I am having trouble formatting the file correctly when PGP signing the file in FLmsg. Next week I am going to get with a buddy who is a pro user and get this sorted.

I stopped, hooked the laptop up to the radio, turned it on and using VarAC on 40 meters connected to N4WXI near Birmingham AL. It took me about 2 minutes to send him the file. His group will inject it into the AmRRon system to be passed as traffic from coast to coast.

After I sent the NIB I continued up the mountain to Ft. Mountain State Park.

Antenna. I decided to use my Chameleon EmComm II ver. 1 for this FTX. Since I would be on the lower bands I wanted a larger antenna. I ended up configuring the antenna 3 times before I felt like I had the right combination. The first time I used my push-up pole to get one end of the antenna about 12-15 feet off of the ground and set it up like an inverted L with the counterpoise underneath the antenna. I didn’t like this version as I had power lines nearby and while I felt the setup was safe I erred on the side of caution. My second attempt was to attach the balun to the camper and elevate the center of the antenna wire in an inverted Vee with the counterpoise underneath it. I didn’t like this way because it left the counterpoise touching the camper and I didn’t want to radiate the camper. They say threes a charm and so it was in this case. I made a loop of cord between the camper and the unun which when the antenna was stretched, it pulled the unun and the counterpoise away from the the camper. The counterpoise was run underneath the antenna and this was the setup I ended up using. The radio was my Elecraft K3(s) and the laptop was a Lenovo Thinkpad T14.

Once the rest of the station was setup, I sent a quick VarAC vmail to my buddy in Alabama to make sure everything was working. My next task was to send out the NIB via Wnlink email to the regional NCS’. The equipment and the Winlink software worked fine. However, I had a fail. The note app on my phone failed to sync across my devices so I did not have all of the email address for the regions. Luckily I had two in my possession so I was at able to get the NIB out partially. One of the quirks of this campground is there isn’t any cell service. A good test of your gear and you.

Issue. App on my devices was not syncing. I am going to move my files to a better app.

After Winlink, I ran FT8 before and after the net. I did so to see if I was operating NVIS. The antenna was configured for NVIS but that doesn’t mean conditions were favorable. My initial impressions were that I was using NVIS to make many of the contacts I did on 40 meters. Forty meters is about the upper limit for NVIS. Between Friday afternoon and Saturday morning I made 121 contacts on 40. Charting out the average signal strength and percent of total contacts leads me to believe that NVIS was in use. More on NVIS in a separate post.

The net ran fairly well, I had 23 contacts and I was able to send the NIB using FLmsg. Flirig, and FLdigi. These apps worked well. The net macros worked well and need only a few adjustments. This completed another task.

FLamp was another story. I couldn’t get it to work right even though I had the most current version. I found out after the net that this version is quite buggy and I should have used the previous version. No cell service, no internet to fix it. Just like real life in EmComm. I will have to fix that when I get back home. Another issue I had was with the antenna. It does not do a good job running a digital net with above normal duty cycles. The balun would heat up causing the SWR to rise lowering the output power. If I run the net again I would probably only run FLmsg. I have a couple of other antenna options to try.

Issue. The Chameleon antenna was not up to the task of running a digital net with a high duty cycle. It would warm up, increasing the SWR. I was running 30-35 watts (I did reduce power). Further research showed that while the antenna was rated higher for Voice/CW, on digital it is only rated for 20-25 watts. This was not apparent on the website or instructions. For digital modes a rating of about 30% of PEP would be about max. My solution is to get a higher rated UnUn and derate it for digital.

Issue. Even though I had the latest version of FLamp, it was buggy and it wasn’t until I got my cell service back that I discovered that. The solution is to find an older version and install that or see if there is a patch to fix the current version.

Saturday morning the bands were in so-so shape. In addition, it looked like some weather was moving in so I broke down the station and started working on the video and this blog post. It was a nice day but I decided to go home this afternoon instead of tomorrow morning. So much to do, so little time.

Even though I’ve been doing stuff like this for 25+ years, there is still a lot to learn. Experience is only gained by doing so I leave you with a quote from Leroy Jethro Gibbs: “Grab your gear!” 73 de Scott.

Addendum. I had a total of 166 contacts. The 45 additional contacts were above NVIS and were not included with the 121 above. Here is a QSO map of all of the contacts.

Winter Field Day 2024

This Winter Field Day (WFD) I operated with the West Georgia Amateur Radio Society. I am one of two CW ops so I got to play CW. We operated under W4F. I typically operate away from the main group so I won’t QRM them. This gives me the latitude to switch bands at will. My purpose is to get multipilers. You get a multpier from working each band. I managed 5 bands. Six meters never came up and I had no takers on 160 meters. Friday night and Saturday morning, prior to WFD, I made a few POTA contacts, had two CW QSO’s and managed to get France on 10 meters. So the antenna was working.

About the club, in general, we are not hard core contesters. We like to do these events for three reasons, we like to socialize, eat, and play on the radio, often in that order. Saturday, John WD8LQT made chili. Along with the chili, we had hotdogs, coleslaw, and various condimets and snacks. My wife Mary K4SEZ, made Graham Cracker Cookies, a club favorite.

I went QRV at 1400 hrs. eastern on saturday. CW during WFD can be a challenge. There are some really good ops that can zip along at 25-30 wpm. I am not one of them. I can usually get the exchnge if I listen to them call a few times. I can send between 16-22 wpm. Sometimes I felt like I was standing still at 22 wpm with these ops at high speed. A lot of times CW ops are operating portable and QRP or low power. I made many contacts with the S-meter not budging off of zero. We also had a lot of QSB and some QRN. You could see the QSB come and go on the waterfall. It was a bit of a challenge, but I felt WFD helped me realize how my CW Innovations class has already helped me. I was able to copy the QRQ stations better than I have in the past. I eneded up making 45+ contacts mainly by search and pounce. I didn’t think I would do well running a frequency — yet. I went QRT about 2200 hrs. eastern Saturday night. I had to leave early Sunday morning so my wife could get to church on time.

Equipment: My antenna was my Chameleon EmComm II ver.1. I ran a 60′ wire in an inverted L withe a 20′ vertical section using my push-up pole and tying off the other end to a pine tree. I had a 50′ counterpoise underneath the antenna. The antenna played well. I have no complaints, it did what it was supposed to do. I think it will be my WFD/FD antenna if I have the space to set it up. The radio was 2nd Peter, my IC-7300. I was running between 35-50 watts. The radio purred along and never missed a beat. I love my 7300’s. I always say that if I could only have one radio, the IC-7300 would be it. For paddles, I used my Begali Expedition. It’s a nice heavy paddle that doesn’t move and is silky smooth. Logging was handled by ACLog WFD edition on my Lenovo Thinkpad.

Everything worked as advertised, so no real changes need to be made to the radios and related gear. We did talk about getting a MESH network between me and the base camp so we can network my computer with theirs. All in all, it was a good time. I got to see folks I don’t see very often, ate good food and ran some CW on the radio. The QSO map is my contacts only. The club is still operating as I write this. 73 – de Scott

POTA Activation K-2169, Me, VaraC, 160 meters and more

This weekend I had the opportunity to activate Cloudland Canyon State Park in NW Georgia. It was a digi weekend with me running FT8 and experimenting with VaraC. I also tried a new antenna combination to see how it would work on 160 meters.

The weather. I book my campsites 4-6 months in advance so I take what I get when I go. This weekend called for rain Friday and was supposed to clear up Saturday PM. It didn’t. It drizzled/rained from the time I got there until 0200 hrs Sunday morning. Since I mingle FunComm with EmComm, this was another test of my gear. The only issue I had was I needed to better seal the window where my coax goes into the camper. You shouldn’t let the weather stop you from going as long as it’s safe. I go year round and because of that, I have a good understanding of my gear and my clothing under varying conditions.

The gear. The antenna was a Chameleon EmComm II ver. 1. This version had a clunky antenna wire and insulator that is more from permanent/semi-permanent installation so I didn’t use it much. This year, Chameleon had a Black Friday Sale of 25% off. I decided to upgrade the wire to a 60′ Kevlar with a winder. I also ordered their new 40-meter OCF dipole which will be used on SOTA activations. I had some 14 gauge Flexweave wire that I cut to 50′ for a counterpoise. My intention was to use this antenna down to 160 meters. I ran the antenna as an inverted “L” ish. The vertical portion went about 25′ up my mast and the horizontal portion was more of a slope and facing north. The nice part was that the entire antenna fit within my campsite. I used the lantern hook on the site to secure the antenna. For rope, I used #36 tarred bank line. The rope is a little sticky so it holds knots well and does not absorb water like para-cord does. I used a clove hitch to secure the antenna ring to the mast and it held fast. The Bank line has replaced all of my para-cord.

The radio was First Peter, my IC-7300 that I bought new in 2016. I use an LDG Z-11 Pro that I have had for 15+ years to keep everything matched up. I was running 25-35 watts. My other IC-7300 is Second Peter. My backup radio was my new KX2. I keep it in a backpack so it is easy to toss in the truck.

Propagation. It was different, not bad, but different. There was a lot of solar activity and I believe it pushed the MUF up above 20 MHz. I had a lot of success on the higher bands which is typically not the case in the winter. My antenna easily tuned 160 meters and I made about half a dozen contacts using FT8. How did I do? I started at about 2030 hrs UTC Friday and finished up at about 2200 hrs UTC Saturday afternoon. I made a total of 325 contacts covering 42 states and 12 countries. Some of the interesting (to me) DX was Angola and South Africa. Both of those stations called me. Angola was on 10 meters and South Africa was on 12. No DX on 40 meters. I had a Facebook request to work 40 meters for local contacts. I did my best but 40 was rather flat this time around. It had the second-highest count of contacts. Breakdown by band was: 10 meters – 18, 12 meters – 18, 15 meters – 13, 17 meters – 7, 20 meters – 136, 30 meters – 19, 40 meters – 90, 60 meters – 12, 80 meters – 6, and 160 meters – 6. One of the surprises other than the lack of low band activity was that 17 meters was fairly dead. Typically on an activation, my money bands are 17, 20, 30, and 40. This time only 20 and 40 panned out. I manage 10 bands at this park in case I want to go for another N1CC award.

VaraC. For the past week, I have been evaluating VaraC mainly for EmComm. There is a lot to like about it. For one thing, it uses the same modem as Winlink. If you have it set up for Winlink, you are good to go for VaraC. VaraC can upload files and low-res pictures. PSKReporter showed favorable propagation on 20 and 40 meters. I made a few contacts with it and did some beaconing. I haven’t tried it yet, but it looks like I can create a document in FLMsg, save it, send it via VaraC, and reverse the process at the other end. pretty nifty. I think pairing Winlink with VaraC just might be the ticket.

Recap. Neither snow, nor rain, nor heat, nor gloom of night stays this operator from completing his park activation… I had a lot of fun. I try not to let the elements stop me from doing what I like to do. 73 – Scott
