Re: [Elecraft] P3 drift

Vic, Remember that the P3 IF is tunable from 455kHz to 21MHz. That means you can tune the P3 to the RWM signal. You will not hear anything, but you should see the signal on the display and can see how much it moves. 73, Don W3FPR On 12/9/2017 11:51 PM, Victor Rosenthal 4X6GP wrote: I think

I think that if it were the K3, then I would hear a change in the pitch of a signal over the first few minutes, and I haven't noticed that. I think I'm going to do a more careful test: tune to RWM (the Russian version of WWV, which is good and loud here) and see what the change is on the K3 and

Hi Vic, I do have the .5 TXCO but also have the ref board attached and a GPSDO which updates constantly and the software I use, NMEATime 2 updates the computer time every minute to 6 digits out. That said, the K3 is always dead on but as to the P3, I never have noticed the P3 doing anything

[Elecraft] P3 drift

2017-12-09 Thread Vic Rosenthal
My K3 seems quite stable (at least for CW purposes) although I don’t have a TCXO. But there is considerable drift in my P3 for the first 15 minutes or so after turn-on. This is noticeable when the span is narrow (5 kHz). I wonder if anyone has thought about the possibility of stabilizing it? Vi
