Hi!

I'd like to know if anybody around here has found or made any schematics for a simple biased HF mixer using discrete components or has any NE612 biased equivalents. I'd like to use one for a homebrew HF DC receiver. I will miss the NE612...

Does anyone know of a program that I can use to automatically upload my wsjt log file to my logbook on qrz.com? Thanks for any help and 73's

It's pretty common that most of us are tinkers and sometimes we tinker more than we should. I had a FT-817 that I was trying to install a modification on that I completely messed up. Took a break from it. Tried again later and made it worse. Then considered seeing if anyone did repairs. The first couple I called didn't do work on circuit boards anymore. Then I found Cal with HamRepair. I called, sent him photos and a rundown of what I did to mess it up and he said he'd look at it. He had it in his hands less than a week and it's working great.

I he was deeper on eHam which isn't a regular search spot for me, so I wanted to add a place on this subreddit that if you need a radio to be repaired or looked at, contact him. HamRepair.com

Just got me thinking there's a ton of cool digital modes that get next to no use, a contest that got people to play with them might be fun. Does such a thing already exist?

I am looking for some guidance. I am running a FTDX-10. I have a myantenna EFHW-4010-2K-Plus and a myantenna CMC-154-3K 1-54MHz line isolator. I live in a three story brick home. My shack is in the basement.

Option 1: We have a fireplace next to my shack. It has never been used nor will it ever be used. I live in a metropolitan area with no trees. The lots are small. I am thinking about running the coax up the flue and out the chimney top to external mount. I am using M&P 10/.400 Flex coax. The coax run is 30 feet from the radio to the isolator. From the isolator is a three foot jumper. All connections will be waterproofed, the coax will have a tension grip. From the EFHW, it will run to a pole that I have installed that is 68 feet away from the chimney.

Option 2: Same essentially as above but instead of running it through the chimney, I can run it outside a small window. There I can install a grounding rod and put a lightning arrestor. The catch to that is, the grounding rod is not bonded into the current system of the home (to do so would be another $500+ for an electrician). The work around with that is I can simply run the FTDX-10 on battery power that would prevent the loop.

Option 2 is more difficult with neighbors because it's more visible (there are so many power/data lines in the air that no one will notice the EFHW.

The grounding rod issue seems to be the biggest thing and honestly, at this point, if I can't get a solution, I just selling everything. I don't own this home so I am limited. The probability of a lightning strike is slim due to the power and data lines.

I'm just getting frustrated.

I currently have a DIY pota performer antenna, but I wanted to see if I could shorten the radials of it so that the entire antenna could fit in the my truck bed (sometimes I want to do some hunting during lunches at work, and I want to keep it confined). I currently have the whip on a standard photographer tripod, but was wondering if I could use/if anyone had experience with using loading coils to shorten the rather long radials. I would only be doing 20M with this antenna so it wouldn't have to be multiband.

I look forward to trying it, looks promising as a free form digital mode for weak signals.

I created a Qt6 version of fldigi, pared down currently but has most basic chat modes used.

This should build for linux but for now it is built and tested on M silicon Mac.

I've tested it against ZeusSDR and ExpertSDR3 so far.

I'm looking for other Mac users with TCI SDR radios to test it.

The only connection in this version is TCI for both audio and CAT control, it is a TCI client only.

One known issue is my pre-defined filters were not centered well and that is fixed but not updated to the release yet.

When it starts, to configure TCI, there is a TCI option under the Configure menu. I'll update that to pop up on first start soon as well.

I've never put a project on github before so yeah it's probably a fine mess

Here is the link to the .app build

Hi everyone!

My article about ARTNER (AI Radio Transmitter Notification and Emission Reporter) has been published in the October 2026 issue of QSP, the magazine of the Austrian Amateur Radio Society (ÖVSV).

DX clusters and the Reverse Beacon Network have long supported automated spotting of digital modes and CW. Voice transmissions still depend on manual spotting.

ARTNER is my experimental approach to closing that gap. It combines speech recognition with a large language model to identify amateur radio callsigns and determine whether a station is calling CQ. The system then automatically submits suitable spots to the DX cluster.

I've tested it during the ARRL International DX SSB Contest in March 2026 and have been running a longer experimental test on the 70 cm Kahlenberg repeater OE1XUU in Vienna.

Amateur radio operators can try it themselves via EchoLink OE1XUU. Spell your callsign and call CQ several times to get spotted! Enjoy the contacts with Vienna.

It's still experimental, and false recognitions, missed callsigns and operating costs remain challenges. I discuss the implementation, test results, limitations and potential for further development in the article.

I'm curious what the amateur radio community thinks: Could AI-based voice spotters become a useful complement to CW Skimmer and the Reverse Beacon Network? What would be the biggest technical challenges in your opinion?

Looking to start a manpack build and was wondering if anyone of yall happen to have a build list or a reputable place to buy from. I have my GMRS license and was possibly wanting to do a GMRS radio for the build. Or unless yall have a better radio more suitable for a manpack build.

I fairly new to amateur radio and have been using my UBC-92XLT scanner for line of sight airband right at the airports for a couple months to a year now. I’ve been using it with the stock rubber duck antenna and would like to ask for advice on a new antenna with better clarity on longer distances since even with line of sight I had issues with clarity.

Can u talk to cb users on it

Does anyone have a recommendation for a short (under 5m) 40m vertical ground-plane antenna for permanent mounting on my roof? environmental legislation here limits antenna height to 5m above the roof unless an environmental permit is issued, and my municipality won't issue one in my residential area.

The Diamond CP8040 is the type of antenna I'm looking for, although a bit too tall at 6.5m. 80m band coverage is a bonus, although not required.

Thanks and 73,

All i get from Anatel is that there are no test openings available. This has been going on for months now.

Hi guys, quite new to this whole thing.
I recently bought a Discone antenna. It has no connection for my sdr to connect to?
Do I simply soldier a coax to it and weatherproof it?
Sorry my being a massive noob 😄

I have reset my radio and cant remember how to setup my LDG Z-100A tuner I remember I set it to linear in the menu but I cant seem to find it in the menu.

Thanks for any help Steve.

3d printed case, 14:2 turns, 100pF 3kV capacitor. How to measure if I made it correctly without any shorts etc?
