Some more notes re: RF performance at my location in Ocean Pines. As noted, there are lots of large trees in this area. I notice that the signalling from the Worcester system is highly variable and the waveform look a little "ratty" when viewed with the UT2 IQ tool. Moving the receive antenna only slightly can make noticeable differences in decode performance, but the RSSI is still variable. UT2 is able to decode the Worcester system and the OC Ocean Pines site in the upper 90% decode quality, and a bit less quality on the Delaware Public Safety system. My refirbed XTS5000 can receive Sussex Fire on DPS while sitting on my desk with only occasional breakups. The G5 receives the Worcester system using the stock antenna with no issues, and the SDS200 does surprisingly well with an unextended back-of-set stock antenna. However, SDR Trunk is unable to maintain lock on the control channel and will eventually go TU when attempting to monitor the Worcester system. I'm assuming this behavior is caused by the fluctuating signal quality / received power level at my location. SDRT will interpret this as a control channel channel change and starts looking for an alternate control channel, but eventually locks back on the original cch. I have a tripod with a simple base antenna mounted that I will place in the backyard to see if that makes a difference - at least that will remove the light building attenuation from the equation, but does nothing about the trees, lol.
