DSDPlus What are you supposed to do in FMP when SDR comes up as Device 0?

[rolypolyman]

See image below. For some reason my RTL-SDR has decided that it wants to be USB Device 0. I have no idea how to change that and Zadig does not see the USB radio (SDRSharp does see it) so I'm guessing it's stuck on Device 0.

The big problem here is FMP will not accept Input Device 0 (-i0). Using -i0 causes FMP to immediately error out.

What am I supposed to do?

i think you are suppose to click the FMP24-CC.bat if you are using a RTL

my FMP24-CC.bat file has this when you right click the file and edit

FMP24 -rc -i1 -b-12.5 -o20001 -P-2.0 -f853.2625 <---- whatever frequency you are choosing to monitor which looks like 155.865 according to your pic

There is no trunking and no control channel. It's just straight single channel, but the frequency uses P25 so I have to use FMP/DSD.

Still it's device 0 and FMP won't accept it.

well I tried to post a video that helped me but it wont let me post it

FMP was superseded a long time ago by FMP24, I suggest you use that as I0 is valid according to the FMP24 notes --

FMP24 [options] Normal operation FMP24 -h Show help Options: -i0 Use first available RTL SDR device [-i0]

I suggest you read up on the many threads showing how to use Zadig. The fact that Sdr# sees the dongle and Zadig does not would indicate you might not have removed the check for ignore hubs and composite parents.

-i0 came out some time in DSDPlus FastLane to be able to use the first available dongle. FMP will only recognize -1 thru -i255. So -i0 is invalid in FMP.
