Re: AirSpy HF+ D1
Ingolf, Have you measured D1 to see if there is any DC leakage? Then check it for inductance & capacity. For replacement of these I use the same diodes used in the Icom R75, 1SS302. They are very fast devices. Unfortunately many SDR OEMs do not post schematics/ service manuals. Good luck with th...

Re: AirSpy Hf+ Discovery audio issue
Try AGC low & dropping the visual gain to -20 to -30. Sharp does sound better, but still very noisy & a difficult listen to my ears.

Re: Audio Clipping
Andy, Thank you for the comments. I have tried several bit settings & qualities in sound card device settings & could not really discern a difference SQ or latency. The audio doesn't seem to change much. The audio meter seems to start at ~70ms & then walks up to ~150ms and then back down...

Re: Audio Clipping
Update. I did find a new Realtek driver & installed that. I also looked at an EQ app ( for my old fart ears) I have on the PC & redid the EQ starting at -20dB upward, instead of 0dB. I retuned the EQ option in Console also. I think all those dB's were adding up to exceeding 0dB into the digi...

Re: Audio Clipping
I've tried moving the VG to every step, to no avail. I've turned off the AGC & tried several ATT settings, to no avail. Tried fast med & slow AGC, to no avail. I've uninstalled & reinstalled the latest Console, to no avail. To my ears it sounds "like" clipping distortion from a...

Re: Audio Clipping
To add more to my confusion, if I record the QSO, it sounds clean when played back thru VLC. Listening to it live is pretty painful.

Audio Clipping
Listening to my Discovery using v3026 & getting audio clipping on LSB 80M. I have had this issue many months ago, posted the issue on the IO group & then it seemed to just disappear. When this happens the "Audio:" gage (latency??) at the bottom left of the display goes well above 1...

Re: Discovery HDR
Hmmm? I see talk about the Dual Port HF+ (unfortunately AirSpy has decided to use HF+ for 2 different units) needing R3 to be modded to get HDR. But the Discovery model already has it enabled. BTW, I have both. Then I see SDRPlayDx (I believe) needing a s/w choice to enable HDR (High Dynamic Range)....

Discovery HDR
I did a search here on HDR and nothing came up.
So here is the question: Is there a procedure/instructions on how to activate HDR on a HF+ Discovery using SDR Console?
Thanx - Bob
