[RTTY] SO2R, small lot?

Don't know - but it is really easy to measure. I would assume if your 
RF voltage is less than the voltage required to damage a transistor, 
you would be OK. I don't know that exact level, but I would guess 
that less than one volt is probably AOK.

My levels were down in the millivolt range (5-50) except for when I 
tx on 40 with a KW, when I got around 300 MV. Hasn't hurt me yet, but 
I cannot operate within 13-15 KHz of that 40M harmonic on when I am 
also on 20.
