Re: Enough protection with antenna switch?

OK, I figured out what is going on... I built this TR switch because the author of the article specifically called out the RSP1. I read on the QST In Depth page that he designed it for approximately +5dBm output - DOH!!! He mentioned that a 0dBm unit could be built using Schottky diodes, but the one...

Re: Enough protection with antenna switch?

I just built the Nu6X TR switch from the Aug QST. It limits the RF voltage to 1.8 Vpp to the RSP1, regardless of the input voltage (65 Vpp at 10W from my K2). This, of course, lights up the ADC Overload indicator. I assume that this level of RF is completely safe for the RSP1A. Am I correct in this ...
