It seems Salem has switched from channel 1 (460.47500) to channel 3 (460.07500) for main dispatch. And are now using channel 1 as the talkaround / records channel. Today is the second day in a row I have noticed this. I'll continue monitoring. Taking the SPD feed offline until I can get more info as channel 3 is marked as "tactical" and now there is no traffic on channel 1.
