I'm listening right now to McHenry Tunnel comms on 463.6375 [127.3 PL]. It is the same type traffic heard on 453.1. I can't seem to mix IF values to result in this freq. Anyone else able to hear this?

I finally got a chance to use a second radio and the 463.6375 is simulcasting the 453.1 freq but I still don't know if it's valid or some kind of IF mix that is creating it. The 463 freq is about 1/4 the signal strength of 453 which makes me think it's a mirror of some sort being caused by something mixing in the radio.

I'll mention here also that if you tune into the scanner webcast at my site between now and 8 p.m. that just Bank 4 (fire freqs) will be turned on while I do some testing.

I've only been home enough to make a few checks here and there, but nothing heard here; possibly you are right, a mix of some kind.
