Monitoring Multiple Marine Frequencies with SDR

Postby royjcropper » Sat Nov 16, 2019 3:41 pm

Good afternoon,

Please could anyone give me some advice as to what would be the best way to go about being able to continuously monitor/record half a dozen or so marine band frequencies using SDR. I don't know which software allows the recording of multiple VFOs or what would be the most suitable SDR to couple it with. Thank you.

this is what i'm using to record/listen to marine band.

if you're ok with linux.
https://github.com/szpajder/RTLSDR-Airband

have a laptop running rtl_airband and recording 24/7.

Thank you very much for that but I don't think I'll be able to get my head around Linux. Was hoping for something more accessible.

the SDRplay devs promised audio saving with SDRUno a good while back but it never happened.

CubicSDR (linux/osx/windows) can save per channel audio but it has opengl problems and slows down to a crawl after an hour or so, but try it it may be ok for you.

SDRSharp has a multi_vfo addon but you won't have recording support.

thing i like about rtl_airband is its a terminal app so can run headless and saves a new file each hour and pretty light on cpu.

SDR Sharp with the Scan add on and just set your pc to record the audio.

Thanks for the suggestions, is SDR Console a possibility?

SDRSharp, VFO plugin, VAC, multiple sound recorders (eg Audacity)
SDRUno, VAC, multiple sound recorders (eg Audacity)
SDRConsole, VAC, multiple sound recorders (eg Audacity)

etc etc

You could feed all audio to one recorder if you don't need the audio saved per channel.

Far fewer resources required if you do it via linux (and contrary to what most people might have you believe modern linux variants have a reasonable GUI and are no harder to use than windows unless you want to tinker)

Thanks for everyone's help with this, doesn't sound like there's a totally straight forward way of doing this yet.
