Re: SDR# issues

Well, I'd try the Airspy group again, prog does have his bad days but usually helps.
But what is "Framework Version: v4.0.30319" my W10 seems to have .NET 4.7

Re: How do I pick up stations/transmissions,

The display is Hz.
So 4625Khz x 1000 is what you enter.

Re: Filters, isolators, bias

Noise can be due to many things, including local interference.
You need to identify the problem.
If it is a RTL dongle keep gain as low as possible, it overloads.
Filters for the frequencies you want can be very useful depending on your circumstances.
There is no easy answer.

Re: Multiple SDRs same Application?

I wrote this some time ago. https://sites.google.com/site/g4zfqradi ... gle#Eeprom I used this with HDSDR.
At the bottom are links to the latest utility written by Joanne.
I guess there are also links and information on this site, most things are covered.

Re: Multiple SDRs same Application?

If I understand you correctly you can use two separate instances of the software.
One instance for each dongle.
Selection will be random unless you rename a dongle, possible but I do not have the link right now.

Re: ExtIO_RTLSDR_u8.dll with HDSDR 2.76 + dongle

I had the same message with HDSDR v2.8

(If Zadig has not been used HDSDR just says no RTL found.)

Re: Help with SSTV downlink from ISS on 145.8 MHz

If it is possible then I'd think a setting parameter would be published or shown by the help function.
The way I would try is to use a SDR program with bandwidth control.
