"However, [PowerSDR] has no knowledge about the outboard amplifier so treats it just as something coming in to the antenna terminal." This isn't 100% correct. There is a gain adjustment control on the FLEX-5000 you can adjust when you place a preamp in the RX loop to compensate for the added

Or use no preamp or the attenuator on the 3K with the ARR. Adding pre-amplification at the antenna is better than doing it after it traverses the coax. -Tim -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Dudley Hurry

Mark, The 3K is pretty hot out of the box, should not need much if any extra Pre Amp and you may be at the point of diminishing returns and amplifying the noise more than the signals you really want. If you can lower the gain of your outboard mixer to a lower level, maybe lower the voltage

Yeah, but unfortunately you still have the same ground loop dilemma with that configuration too. It is still best to electrically isolate the second source. You do not want stray currents flowing through the speakers, especially if they are high frequency (RF). -Tim -Original Message
