[Heathkit] clearing up my couple or three questions

[Bob Young]

Oh just to clear up my question, I meant ground the radio antenna terminals 
with no antenna hooked up (to the radio) while transmitting and also maybe 
ground the antenna terminals (of the radio). I will check around for a 
switch. It says in the manual that there is RF across 3,4, and 5 while using 
coax, they are directly connected to the coax outputs, I think the 2060A 
fixed that problem.
