Hey guys, long time lurker and infrequent poster.
I've been monitoring LMRN off and on for a couple months and for the longest time I could park my SDR on the 142MHz control channel for the Windsor or Essex tower and it would sit there all day. Over the last week or so, the Windsor tower has been working like normal, but when I tune to the Essex control channel (142.6650) I get a good signal for a second or so then it switches over to 856.55625MHz and I get 0 signal.
I'm running an RTLSDR with a NooElec Flamingo FM stop filter and a LorNA on the hardware side, and Unitrunker 2.1(with chase and discover disabled and dwell set to 1500ms) on the software side. I haven't updated Unitrunker or made any other changes since I started having this issue. I don't think my antenna is causing a problem as it works fine for the Windsor P25 system and MPSCS, both in the 850 MHz area.

@mciupa: I could probably stand on my balcony and see both of you. Have either of you noticed anything like this from the Essex tower?
