Re: what are the "Dither", "Random", and "PGA" options in the radio settings panel?

Since I posted in the RX-888 subforum, I had assumed it would be obvious that I was talking about the RX-888.

Re: VHF/UHF performance (and LF/VLF too!)

Longwave performance is, in a word, poor. I've seen other posts saying that the design of the Bias-T circuitry acts as a filter below 500kHz, and a quick glance seems to support that. It's not completely deaf, but only strong signals are going to get through. (Curiously, the 60kHz time station in my...

Re: what are the "Dither", "Random", and "PGA" options in the radio settings panel?

Which front end? The one built in to SDR Console 3.2 -- although I've seen pics of the ExtIO that have at least "Rand" and "Dither".

De-selecting "PGA" seems to drop the noise floor about half an S-unit, but I don't know what it's actually *doing*.

what are the "Dither", "Random", and "PGA" options in the radio settings panel?

I don't see anything about them in the notes that come up with the "Options" button, and the "Help" button doesn't seem to do anything.

Re: SDR-Console with Wine (Linux (Mint))

SDR-Console does run with recent versions of Wine. It won't see any USB-attached devices, but it seems to work as expected with network sources.

Re: audio timing glitches when using CUDA

Reverted from 3.11 to 3.09, the oldest version available on SDRplay's website.

Decodes with "Stereo Mix" work fine. Decodes with VB-Cable are horrible.

I'm out of ideas.

Re: audio timing glitches when using CUDA

After much experimentation, I've come to the conclusion that the blame doesn't lie entirely with SDR Console. I could get no combination of the audio latency settings to produce anything resembling acceptable output. Glitches were always large and frequent. Then I decided to try skipping the VB-Cabl...

Re: audio timing glitches when using CUDA

Since posting the first message, I've replaced my i5-3570K with an i7-12700F. Sometime prior to that, Windows finally decided to update itself to 22H2. Not only are the glitches still present, they're now as bad without CUDA as with it! (As before, using any other SDR software is flawless.) I'm wond...

audio timing glitches when using CUDA

I'm running the latest SDR Console release on Windows 10 21H1 Home (my system has never offered to update past that version for some unknown reason). Hardware is a Core i5-3570K at default clocks, EVGA GTX 960 at default settings and latest firmware. Radio is SDRplay RSPduo with API 3.11. One thing ...

Re: Band Plan text placement

I would also like to see the capability for multi-row band plans. The American 80-meter and 40-meter ham bands have substantial overlap with broadcast bands.
