I just moved to the Valley from Buffalo, NY. In all honesty, the only real active frequency up in Buffalo is 146.52 MHz. There's a group of guys in there every morning from about 6 AM -10 AM and then again from about 5:30 until midnight (1 or 2 on the weekends). If they weren't there, no one would be listening.
Same story. People would complain.
It amazes me how many hams don't understand that the ARRL isn't a law or policy writing body. It's an advocacy (lobby) group. It suggests that 146.520 MHz is used as a calling frequency, but it's not required by law.
The fact of the matter is, if there isn't chatter and people have no reason to go there, no one will... and to the few stations that always say, "I have good ears, I'll monitor 52 for emergencies once the rag chews go away," can you really be by your radio 24 hours a day, 365 days a year?
With that said, what exactly are these link frequencies? I have found two, but what about the others?
