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?

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

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 ...

Re: Will this compromised antenna work?

Brian,
With two successful activations under your belt, I'd have to say that yes, your antenna works!
