It's an 800 MHz H09UCH9PW7BN with Host 7.00.02, DSP 7.03.06, and a FACTORY flashcode of 5000080000001, meaning it has IMBE/Proj25, Smartzone, Digital ID Display.
The problem is while transmitting, there is a HORRIBLE hum in the background. My voice is barely heard at all on another radio (analog). When I go into digital mode, the hum is so bad that you can't hardly hear the usual data (P25) sound. I haven't really been able to test RX, since the radio hasn't been programmed, but I think that is ok. Everything else about the radio seems fine. What is wrong???? Please help...
Thanks!!
Oh yeah, I tested it with a speaker/mic and had the same problems. No difference...
