but... It is still intermittent in some functions. If the generator or spectrum analyzer fail,
the frequency counter still works. Then, when I go back to use the generator, it is working.
And it seems to stay working once it starts to work.
So I have replaced all the electrolytic caps, but in the HV supply, all the voltages are normal,
and when it works, it works well.
I had an intermittent RCA connector that I repaired, and the switching circuit seems to work
properly, but as the problem is intermittent, who knows
Has anyone else had the generator and spectrum analyzer quit but still have the frequency
counter still work? When the spectrum analyzer quits, the noise display is quite large.
As I am still learning to use the functions, I do not know what else may be failing and what
keeps working. Is there something else I should check?
