[TenTec] RFI into Orion II

[Sergio Escudero]

Hi to all, the problem is the ground with the microphone (must) be separated from the chassis ground, separate the mic capsule ground from the shield and radio chassis see figure 2.4 of mic connection  me and a local friend we have wire several mic to the Orion2 , this will fix the RFI problem W4ESA

 Don't know if anyone has mentioned this yet, but Tentec, a few years 
ago, had a small board that fixed a problem with RF getting into the 
Orion II mic input.  When I bought my Orion II second hand, I called 
Tentec to see if there were any engineering changes that I might apply 
and they told me about the board and sent me one for free.
