Re: [Elecraft] K60XV Problem
Don, I adjusted the VCO range and ended up with 0.551 vdc at 5000 kHz on the meter and I can now receive WWV at 5000 kHz. Apparently thats enough voltage to work. What I did was adjust L30 so the voltage at 4000 kHz went from 6.52 vdc to 7.35 vdc. All voltages are between 2.715 vdc and 7.350 vdc on the meter.

It is normal for the VCO voltage to become so small below 5300 kHz that the tuning will not continue on down to 5000 Hz. Also the response of the bandpass filter may fall off quite a bit at 5000 Hz which will reduce the ability to hear at that frequency.

I installed a 60 meter board last night and it seems to have a problem. When I entered 5000 kHz I had what sounds like a loud oscillator sound on the audio. I turned on another radio and had WWV loud and clear at 5000 kHz in that radio. When I increase the frequency the oscillator sound goes away (maybe just beyond my hearing) and I hear a very faint sw station at 5070 kHz. Between 5070 kHz and 5300 kHz I can't hear the buzz saw and I adjusted the trimmers for max power out. I'm not getting any error messages on the display. So far I haven't found any visible assembly errors. Has anyone had this problem before? Any ideas what might be bad? On a previous K2 I built with this option I heard WWV right away at 5000 kHz.

Re: [Elecraft] K60XV Problem
Thanks Mark. My other K2, S/N 5022 receives WWV on 5000 kHz real good. This one is S/N 5404. Last night I tuned my Sony 2010 receiver to 5000 kHz and it almost pegged the meter...the path just happened to be open. I'll let you know if I am able to get this rig to do it.
