Re: Ctrl Panel & Main SP different freq.

With a SR of 10 MHz and a DEC of 1 in the main window you have an IF bandwidth of 8 MHz. Each of your spectrum displays appear to be zoomed in and SCROLLED to different sections of the total IF bandwidth.

Re: Antenna ports

Replacing the RF blocking coil on the bias feed with a proper sized one (larger) would cure this... Not sure why a bias-t is included in the RSP since its need is antenna dependent and the bias=t belongs on the antenna side of an external antenna switch. With some circuit board hacking it might be p...

Re: HDSDR & SDRuno on one PC?

Before SDRuno version 1.12 you could have SDRuno, HDSDR and SDR# all loaded at the same time and just switch windows without having to close and reload each of them as long as only one was streaming at a time. It's quite convenient to not have to keep reloading SDRuno all the time as it always loose...

Re: what can it be this huge interference.... ??

I have an ALA1530LNP and RSP1. I have found it necessary to ALWAYS have a MW (AM broadcast band) filter connected between the antenna and the input to the RSP (unless I'm wanting to chase MW DX in which case I replace the filter with a 20dB pad). The ALA1530LNP is very efficient at the MW frequencie...

Re: Interference identification?

Are these PLC modems susceptible to any kind of interference that would make them inoperative?

Re: Tuning

I would like to have different step sizes remembered for each mode. i.e. AM=5KHz SSB=100Hz
