(((EditToAdd: Newbie replies are in purgatory, but upped a new pic of CPU running pretty low. Also, I wasn't clear, but I am using UniTrunker to feed DSD+.
Also: With great thanks to mtindor I think I am wrestling with this: https://wiki.radioreference.com/index.php/Simulcast_digital_distortion
Also,also: Becoming more accepting that mtindor is right and I'll have to dig in to FMP docs and figure it out. But if I lose TRecorder function I'm toast. That is the software that made this fun again lol. Maybe I can run UniT next to FMP to just feed TRec while FMP controlls. Ok back to reading.)))
Banging my head against this wall trying to figure out why DSD+ Fastlane gives tons of errors and voice sounds horrible. I am very RF amateur, but pretty good with computers. I think (maybe?) it is in my VAC setup or Windows recording levels, but can't nail it down and as last resort I hope maybe someone can point me in a good direction.
Basics: 4 RTL dongles. A single no-name which is the signal stick, and 100% health and I think out of scope.
Then I have 3 x rtl-sdr.com sticks, each doing voice duty. Each voice stick feeds into an even numbered VAC and DSD+ outputs to the odd numbered VAC above it. VAC #1 locked up a few weeks ago, and instead of fight it, I just made a new one and VAC1 is dead to me. Assume I have the correct VAC# feeding into DSD+, its confusing maping VAC# to whatever arbitrary device table DSD+ uses which changes each boot-up
Voicemodel ---> VAC2 ---> DSD+---->VAC3
2Voicemodel ---> VAC4 ---> DSD+ --->VAC5
3Voicemodel ---> VAC6 ---> DSD+ --->VAC7
I am using the command line arguments from dsdtune ran on the same input file I have shared.
Screenshots and input.wav from hitting R in dsd+: https://drive.google.com/drive/folders/1jz4rF-zke6K-BRPzHDrZpKzQoN-JfQQS?usp=sharing
After spending many hours getting the signal stronger with some better antennas, I'm realizing something is off and I don't think it is signal. I get a 40ish SNR when testing in SDR# via mouse hover while tuned to control channel on all Voice dongles. So assuming that I have spent this evening trying to figure out why so, so, so many errors pouring out of DSD+ and why the voices sound horrible.
I think I have narrowed down to these symptoms:
- When I put UniScope on an even # VAC coming out of Unitrunker, and switch it to CQPSK, the 3-eyes are constantly scrolling right to left. I can kind of control the speed of the scroll and slow it down by adjusting the recording level of that VAC upward, but it never gets to a static point.
- Just the normal scope view in DSD seems to have the waveforms moving horizontally, instead of other videos I have seen of functioning systems, where it seems static waveforms pop up and down in the same spot.
Any thoughts??? Please??? I have it so close to working awesome, and the voice quality is really just horrible. I can take video if needed but hoping to avoid.
Also,Trunking Recorder screenshot is just to show how much I love that program and it's simple web server, etc.
EditToAdd: hell here's a link to the TR if you want to hear a crappy sound version of Baltimore PD lol, (I'll probably remove this later, don't have bandwidth to serve the public, change to http): hteeteap://weakerthan.dyndns.org:888
Thanks,
