Re: RF "surges"

This is probably due to a strong signal (not necessarily showing in the displayed b/w) coming on and off and causing the AGC to act. It may help to read the following document:

Re: RSPduo Bias-T

It's worth checking to see if the voltage is appearing at the tuner 1 port instead. The rsp2 suffered from swapped-over ports a few months ago and it caused great confusion!
