[Elecraft] Re: K3- TX off frequency

[J. Heide]

I found the problem. The "-S" was showing on the display for sync AM, which doesn't look like it's working yet. I had programmed this to PF1 for when it is activated, and had it on in SSB mode.

Subject: K3- TX off frequency

I have the K3 put together, went well, but I am having a problem. I did the reference oscillator calibration using an Agilent frequency counter with a GPS reference (I use this setup to set my 100Mhz reference on 6GHz digital microwave equipment). I was testing tonight with my friend and he was having trouble hearing me, stating I was off frequency on TX. Our dials matched for me to hear him fine, and he never had issues when I had the K2 running, our dials matched. I checked my TX on my IFR1900 and found I was low in freq by 900 Hz.  XIT is off. Filters are FM in FL1, AM in FL2, 2.7 in FL3, and 500Hz in FL4. Data was entered from the crystal filters properly (I think, looks fine). Where should I look to find the trouble? I'm stuck on AM right now since it is more forgiving frequency wise.

Thanks,
