Actually, that was my point. If you have the frequencies in your radio already, then you should not need to ask these questions. If you are hearing radio traffic, then the frequencies are active. You should also be able to figure out what a frequency is used for if you listen to it long enough.What is this?
On my pro-160 i use the supplied pull up telescopic antenna and only the 160 for conventional analog stuff
the psr-400 that im waiting for will be for analog trucking system and will use a 800mhz rs rubber duck antenna. Im not to far from lga and about 20min from jfk and i get both system loud and clear. I dont know what part of L.I. your in but you should pick up both airports without a problem. Lately i have been listening to ny nj port auth and its very very active. lots of crazy stuff going on at the airports.
