Carlos,
I will do that when I get into the shop tomorrow. From your suggestion,I found
these two other things I can look for in the frequency counter:
1. https://www.eham.net/ehamforum/smf/index.php/topic,26529.0.html
2. The digital whining from DL1CYP's Ten-Tec 544:

across all bands and it is in the background. It measures about 1khz and
will vary harmonically when I slowly turn the VFO thus changing the 100s
hertz digit in the display. The waveform changes back and forth between a
sinusoidal and a rough sawtooth. I can mask this tone by turning up the Rf
gain but its still there. It is pronounce when the Rf gain is turned down.
