Hi Andy and all,
Good for you, congratulations on nailing them on 160m. It looks like even on
20m they are at their best between midnight and 4am EDT. I have resigned
myself to some sleepless nights in order to nail them. For me it
is WSJT commanding the K3 to go
Split and then waiting for confirmation. This has been discussed before. Also,
I use VOX and we still don't have VOX settings remembered by mode, so there is
constant fiddling to get the VOX to activate.

I suppose that you're addressing this to me, but since you didn't quote any
prior message, who knows.
I realize that Elecraft's position is that VOX is a no-no. However, CAT is a
PITA no-no for me, particularly when Microsoft reassigns comports Willy-Nilly.
There is a reason for using "real"
t;
Since abandoning AM using my DX100 where a front panel switch initiated T/R
switching and some use of a VHF multimode using PTT, like Jim, I've never used
anything but VOX on any audio mode.

If it's like a KPA500, you can have it go to Operate when powered on. Menu "PWR
ON = OPER"
Caveat, I don't use the K3 to turn on the amp. Separate operation.

I realize that contest software does the same guessing these days, but I don't
regularly operate in contests, so I use my regular log and type it in myself.

t happened again but this time I got the gist of
what it was. JTAlert was informing me that my QSO partner was/had been sending
me a text message informing me that he had my report and I should be sending
RRR. At that point I stopped transmitting and unloaded the software. Nuff said.

Wes,
you're taking that out of context. The structured messages allow for
redundancy if some of the original message is missing. The decoder can take
the sync symbols so that the system can understand what type of messa

Maybe they're making up for 20-meters where I called and they came back to
N7WH. I sent my call twice and he finally sent it correctly but must have left
the log wrong. So I worked them again. I did also get them on 30 and after
working them on 17 CW and SSB, I broke down and let

I fired off a letter to my US Senator, who happened to be K7UGA, requesting
