I have an old crystal controlled Regency scanner. One of the channels is Marine channel 16. Today I picked up the East Brunswick FD on that frequency. I can tell it's not exactly on frequency as it has the distinctive sound of someone talking close, but not on the frequency, like they're on 156.790 or 810. I thought EB used a digital system for the fire department (paging is analog) but this is regular communications I'm hearing between the dispatcher and the engines. Any idea why I'm hearing this here?
