Continuing with the casual exploration of what can be heard on VHF, I caught an interesting one today. This morning, Fri. Jan 21, 2011 at 1320 to 1335 UTC (8:20-8:35 local time), I found a frequency that CBC Radio reporters use to talk to the studio. At least that's what I heard. Specifically, I heard a silent carrier on the frequency from 1320 to around 1330. Then one half of a conversation was heard. I already thought this was a CBC feed so I turned on an FM radio to CBC Radio One at 99.1, and heard the same conversation there. The CBC was broadcasting the news and the anchorman was talking to a CBC reporter at some location. What I heard on 152.87 was that reporter's half of the conversation. According to RadioReference.com the callsign of this CBC media feed station is CJY241.
I actually first heard this station on Jan 14 (that's why I was sitting on the frequency today) but on the 14th I didn't hear enough material to ID it.
There's such an incredible variety of signals on the radio bands and I'm always surprised when I discover yet another way in which radio is used.
