I am hearing control channel data on 852.2125, this frequency is listed in the database for the Fort Worth/Tarrant county PS system, but not as a control channel. This is causing my Pro 106 to lock onto the signal every time a talk group uses that frequency. When the transmission is over, all I hear is data, and it remains that way for a few minutes, I can hit scan and it will resume normal operation until the FWPS system transmits on that frequency, then it locks up again. Part of the time the signals sound like intermod, with voice traffic trying to break in.
