I just received a -2 unit, and did a preliminary test on a local 700 P25P2 system using the included telescopic antenna, unextended as this is a 700 system. I initially had to switch ports for the device to be recognized and communicate with the W10 host, but a firmware update initiated, and I manually entered the cch. The device began decoding and producing audio immediately, but tbh I was not as impressed as other have been with the quality of the decoded audio. I'm going to run a test with a different antenna, but in the meantime, can anyone suggest any settings / adjustments that need to be made out-of-the-box? My Unication G5 and SDS produce superior audio on the same system, as does OP25 (after dialing in the precise parameters) and SDRTrunk without much intervention at all using Nooelec dongles.
