Streaming 3 analog channels...

[Forts]

I'm looking for software options (Windows) to stream 3 conventional, analog channels from 1 Airspy Mini (my desired frequencies are approx 4mhz apart) out to 3 separate feeds. As far as multi VFO software goes, it looks like SDR#, SDR++ or SDRTrunk maybe? (not sure if it'll do what I want with conventional stuff). I'm looking for the most CPU efficient way of handing this. Currently I'm running 3 RTL dongles via FMP24 -> VAC -> Scannercast (along with several other apps like TwoToneDetect, Trunk88 and DSDPlus) on an older Core i3 machine, with plenty of CPU to spare. This setup works ok, but I'm just looking to consolidate hardware and points of failure by rolling things into 1 package. Suggestions?

Running on Windows? No such thing as an all-in-one for that stuff.

SDR's my entire system runs on Trunk-Recorder Dockers. Then they all feed into this.

Analog I just use a scanner and feed into this GitHub - aaknitt/voxcall: A sound-activated recorder with support for uploading audio to Broadcastify Calls

Thanks! I really need to take a closer look at rdio-scanner. And yeah, I know I'm somewhat handcuffed by Windows.

SDRTrunk has a NBFM decoder. It's a newer feature so it's still a bit clunky. I run a feed of the local NWS station from SDRTrunk and it works quite well. It's definitely worth testing out, especially since you're on Windows.

You may need additional tuners. There is no "scan" function on SDRTrunk for conventional frequencies. So you'd have to monitor all 3 simultaneously.

Yeah I'm not looking to scan anything. 3 channels in, 3 channels out basically. I'm going to setup a new PC this weekend just to play with different configurations of multi VFO stuff and see if I can find something that fits the bill.

So I spun up a new machine yesterday using an AirSpy mini and a regular rtl-sdr dongle, using SDRTrunk. Have 4 NBFM channels setup in the software across the 2 dongles, then feeding into RDIO-Scanner. Works very well! I went 1 step further and piped in audio from a DMR mobile using voxcall and it works dynamite! I see this becoming a new obsession now with seeing how much I can shove into it.

Using an older Core i5 machine with 8gigs of ram, CPU load is sitting at about 30%.
