Inrad sells them. They made the OEM filters.

More rigs with diversity reception:

[Elecraft] KPA1500 front panel locked

2022-12-14 Thread Gary Johnson via Elecraft
Helping a friend connect his KPA1500 to a K3. The AUXBUS is working, following 
the radio etc. like normal. However, as soon as that cable is plugged into the 
KPA, it’s front panel buttons all cease to function. Remote control via USB or 
ethernet work fine. The AUXBUS cable is a proper one, not a VGA cable. I’ve 
never seen this before and can’t find any reference to a locked front panel.

Re: [Elecraft] K3 drive level for Q5 Signal 432 Transverter

2022-02-27 Thread Gary Johnson via Elecraft
Sounds like you should do the low-level power calibration using the K3 Utility. 
For now, you can increase the maximum, up to 1.5 mW, and presumably get the 
desired output.

Re: [Elecraft] K3 Frequency Calibration

2021-12-18 Thread Gary Johnson via Elecraft

Not sure why nobody has mentioned using WSJT in frequency calibration mode. 
It’s the bottom selection in the Mode menu. Shows  your offset in Hz to about 5 
decimal places. Just pick from the list of standard freqs and away it goes. 
Then adjust the K3 ref frequency to walk it in. There are even guys doing 
long-term observations on Allen variance this way.
