After extensive testing today, in MY case that while DMR works great with the WS1080 firmware into the GRE PSR-800, however for some reason made a P-25 VHF Motorola Trunked System also in the scanner more difficult to receive (there were NO programming changes in any way). Keeping in mind that it is a “border-line” weaker marginal system for me anyway, but I was only decoding about 1/2 of those signals (as verified on another scanner), where as before it was 100% copy before the DMR. It did NOT affect conventional P25 (non-trunking) signals in any way.
So after a huge “sigh” , I reverted back to the original U2.0 CPU firmware / U1.3 DSP firmware and all is well again.
Thank goodness it’s not difficult to go back. Eric’s excellent program allows for you to switch back the CPU (and the DSP is put back using the PSR-800 EZ-Scan interface after). Oh well it was fun playing with it anyway. Anyone have any idea's here ??
