[TenTec] poor audio on OMNI-V

[John Graves]

If I may jump in with a question.  I have a jupiter but my Drake 2B rcvr 
might need this, after I recap it.

I have a MFJ 259B antenna tester, which will work as a frequency counter 
that does resolve to 1 hz.  Do I need to build a probe with a clip on 
the outboard end, or is placing my antenna close to the circuit 
sufficient? There is a max of 5V Peak-to-peak on the input of the counter
