[hpsdr] PowerSDR Gain settings

[Chris Smith]

Hi

Am I right in thinking that the Gain by Band (dB) settings in PA Settings on PowerSDR should reflect the total gain after Penny(lane)?

If I'm interpreting this correctly then assuming a mean gain for Pennywhistle of around 40dB LESS the 6dB pad I have on Pennywhistle's input PLUS the 14dB mean gain of my PA the TOTAL gain = 40 - 6 + 14 = 48dB.

Should I set the Default gain to 48 or all band gains to 48 before doing a Calibrate with a Cal. Target of 100(W?)? What is the Advanced Calibration Routine?

I'm asking because I think I've destroyed the pair of MRF454s in my PA by over driving them. :-(  I believe I should have had a 12dB pad on the input of Pennywhistle to limit the input to my PA to 5W.
