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.

Re: ExtIO_RTLSDR# - custom ExtIO for RTLSDR

I suggest you try HDSDR v2.80.
Then report if it still has a problem.

Re: SDRSharp -v- HDSLR

This needs clarifying. IS it really a V3, the model with direct sampling? If so the -40000000 offset makes no sense. I note https://www.rtl-sdr.com/rtl-sdr-quick-start-guide/ mentions counterfeit ones. I do not know about RTL direct sampling with HDSDR just that a particular DLL has to be used and d...

Re: SDRSharp -v- HDSLR

" difficulties in getting HDSDR to match the sensitivity of SDRSharp" This I do not understand. The waterfall displays of various SDR software vary, some might be better at showing weaker signals visually but I never read any comments about the basic sensitivity varying between programs. This is set...

1 RF Front End calibration
2 Think so, not sure

Re: Sigmira: Sr. Citizen Woes

Bob,
Why the insistence on Sigmira?
If SDR# works why not use that?
Or HDSDR or SDR Console? These are far more popular, better known and work well.
Sigmira is only useful for the few odd modes it can decode, if you can find them on the air. If you can get it to work...
