I am using the TRX-2 in the remote head arrangement with a dual band vhf/uhf antenna. If there is a configuration issue then it is knowing the right software settings to make the P25 audio decode better. That's why I want to use an actual P25 radio since it is tuned specifically for that band, unlike a scanner, and will know what to do when it receives a signal.
You lost me. How does the scanner come into play here? You said you can hear the dispatcher fine but then you don't hear the trooper. I guess the scanner is working well then, eh? Try a different antenna. WSP is on VHF so a dual-band is not the ideal configuration. Try a VHF 1/4 whip or a scanner antenna. Are you using a magnet mount?
I felt that using a dual band vhf/uhf antenna with at least twice the gain of a shorter, vhf/uhf/900 mhz scanner antenna was a better choice. It is not a magnet mount. I could hear dispatch because I was close to the Kalama and Rainier transmit sites, not that that is a big factor because I can usually hear them all around Cowlitz county. The trooper was behind me a few miles on a flat section of freeway and a 50 watt mobile should be heard further than that. The scanner is designed to pick up frequencies from CB to 1300 mhz, not focused on just P25 vhf like an actual Motorola radio. I had the IWN frequencies locked out because they were inconsistent and transmitting signals from outside of my area, even with the desired talkgroups programmed in. Regardless of the advertised specifications, the TRX-2 does not scan as fast as my Uniden 796D, but the remote head feature makes it fit better in the front of my car.
