This should be no biggie. I too have Omni 6 Opt 2. Note sure if the Bengali has a open collector sinking driver output (i.e. a 2n2222), but that is all it would take to key the Xcvr. 73, Don KO7i The

Cecil, You are spot on. A direct ground strike will develop up to 400 kA-pk. At 5 ohms that is a serious voltage surge. The Voltage Surge will have a very fast rise time (less than 100nS), the curren

Barry, I have no doubt that the INRAD filters work very well. I would love to replace all of the TT CW filters in my 6 with INRAD's. Only one thing keeping me from doing that - the war department! :)

I have not damaged my 6 opt 3 using the relay to key a Dentron Clipperton L amplifier. I do use a MFJ auto tuner between the amp and my 6 to reduce VSWR between the untuned amplifier input and my 6.

Power dB = 10LOG*(P1/P2). Question #1, do you have a calibrated volt meter? Might be useful to check your input voltage. Question #2, is your "50 ohm load" calibrated? Question #3, I am not familiar
