ATS-20+ with ATS20_EX firmware

The ATS-20+ is an SDR receiver that covers from broadcast AM to broadcast FM. The SDR runs on an arduino and the firmware can be modified and updated by the user. I installed ATS-20_EX from https://github.com/goshante/ats20_ats_ex and it's a game changer! The radio went from being a toy for SWL list...

Re: Elecraft KX1

I agree with Richard - I don't use my KX-1 as much as I would like but I always enjoy using it!

Don,
I don't have a G90, but I've used a digirig successfully with an FT-817 and a (tr)uSDX. According tot heir website, they make cables for the G90.

Re: tr USDX doesn't work.

Tom, What do you get when you apply power to the radio? You should get a screen with (tr)uSDX in the top left corner, and the frequency and other info on the screen. If it turns on, can you hear any signals? Can you transmit? How exactly are you trying to upload new firmware? Are you inputting your ...

Re: tr USDX doesn't work.

Tom, Have you tried downloading the firmware using the serial number on the bag? If so, what happened? Do you know what version of the software came installed on the radio? Who was the seller on Amazon? I bought mine from Malahit and it works fine. Based on the issues you're having, it may not be a ...

Re: tr USDX doesn't work.

Tom, I have a couple of (tr)uSDXs, so I think I can help. The radio should have come with the serial number on a sheet of paper or something similar. I bought mine as kits and the serial number was on the parts bag. Are you trying to install the latest firmware using these instructions? https://dl2m...

Re: Fara-J fabric J-pole for 2m/70cm

I don't think that design would work with the materials I used for the fara-J - the nylon webbing is only 1 1/4 inch wide. Maybe you could run two strips of nylon from a couple of spreaders though. The faraday tape is pretty cool.

I found a video for a 4:1/9:1/16:1 combo. I'll add it to my to-do list.

Re: Will this compromised antenna work?

I was uncertain, but the AX1 continues to amaze me. A compromised antenna is, first and foremost an antenna. Brian, Location is also important. I have a homebrew DS1-type antenna (6 foot whip and a coil at the base). I can make contacts here in the lower 48, but I couldn't even hear anything on it ...
