I have a Pro 197 that is fine, it is running 2.0 , is there anyway I can go back to the 2.0 , since I don't have it on the scanner and GRE website, ( which I was surprised the Firmware page was up) only has 2.1
I highly doubt that reverting to Firmware 2.0 will solve your issue. Be sure, before you start messing around with your firmware that you are running Firmware 2.1 and DSP 1.4. Up here in the Cleveland area we have 3 P-25 systems and the PSR 500 running 2.1 &1.4 does very well. If you are using a rubber duck antenna sometimes just moving the scanner a couple of feet makes a difference.
If you don't get the earlier firmware file and corresponding DSP files you cam PM me and I will setup a download site that you can get the files.
By the way, there are different update versions you should use depending on what Boot Version your scanner is running (Prior to 1.4 and 1.4 and later).
