Do any of these programs decode P25 audio?

Great news and thank you! I tried 2.5 and yes, I'm getting much better performance with my USRP B100. I notice less use of the CPU but still having major issues if I adjust the gain in EXTIO or move the 'grey' band slider in HDSDR. I loose contact with the B100 and have to restart, unplug/plug the B100 and none of those options are a guarantee of getting it online again. But thank you again for the support. Great program when working!

Best,
Ka2zey

I have been playing with HDSDR V2-50 - using it with a SoftRock fixed frequency SDR as an IF in my Kenwood R2000. Works very well - I can see almost +/- 50kHz of any HF frequency and the audio is very good. When I set it up carefully, the frequency is spot on.

However the I/Q phase/amplitude balance method to get rid of the image frequency is poor. It only works if you put the signal on the same frequency as you set the balance up on - in the instructions +/- 10kHz. Otherwise it's useless. Any chance that they can come up with an automatic method of balancing as in Rocky and SDRSharp? Looking forward to V3?
