Re: Digital Mod FT8
I've noticed that my radio sets its time automatically after a few minutes if I have the USB cable plugged in. I have not yet found the code that makes this happen, but I'll get there eventually.

Could the FT8 mode also be integrated into the T41? It would also be nice if there was a way to set the time. Best regards, Wolfgang

NA that was "cheapest rate" ship. I cannot for the life of me why shipping went thru the roof recently. There is no reason for it unless the carriers just don't want the harder business/ want to stick

Re: Help: Audio is pumping on bands 17 and 15.
Well, I think 3 seconds is ok... keeps you from pressing the button twice accidently and having the radio come right back on... You could probably cut it to 1 second though... Dr. William J. Schmidt -

Re: Help: Audio is pumping on bands 17 and 15.
