Can anyone suggest other SDR receivers that work well with SDR trunk

[Brian pfister]

Looking for other options beyond Airspy & RTL-SDR USB receivers that have good success with SDRtrunk. Perhaps something with about a 5-6 MHz spread similar to an Airspy mini, as those don't appear to be available right now.

I can get a full 10MHz with the SDRplay RSP1A.  I would think the same applies to their RSPdx, though I don’t have one to try it out.

SDRTrunk does not support any SDRplay products today. There is an experimental fork that attempts to add some support, but it seems to be a bit stalled at the moment (it basically works, but needs refinement). I'm poking at it a bit, but don't have a lot of time (nor skill) to put into it.

The RSPdx is supposed to support up to 10M sample rate. For some reason (not yet explored), the experimental SDRTrunk fork doesn't allow IF Bandwidth beyond 8M. 8M is enough to cover what I need, though, so that's not a problem.

Another option is a HackRF One ("genuine" or "chinese clone"), which supports up to 20M, but nowhere near as good a received as the RSPdx (at least in my experience with a "chinese clone"). I've never tried the AirSpy products, so can't compare to those.....

I’m working on updating Sammy1Am’s fork to support the SDRplay RSP1A with a revised approach to the settings.  In the larger scheme of things they are minor updates from all the work Sammy1Am did.  However, I think may make a big difference in the way SDRplay devices perform and go a long way to paving the way for the RSPdx device and its multiple antenna support.  I don’t have the RSPdx or I’d include it in my work.  Perhaps later I’ll buy one, but for sdrtrunk’s P25 needs the RSP1A is more than adequate.  I’m getting a full 10M from it in sdrtrunk.

 

I’ll be uploading to my GitHub account once I’m done, getting pretty close to something worth sharing.

airspy r2 is great and its available in us store

[Brian pfister]

Tried ordering from the us store, but have not received any response from them in 3 weeks, very strange since done business with them previously & always received good service.

I use multiple RTL-SDR R820T2 receivers  it works great with SDR trunk I was using only 1 Airspy R2 but would miss some of the calls even at 10 MHz

[Brian pfister]

Did you have to change the serial numbers on the RTL-SDR receivers to make them work properly.

[Shon]

No, I did not it works automatically no problems   have 2 of them  set up on  P25 Phase 1 System
