You must have an amazing radio if you're picking up San Francisco from Tampa Bay, Florida.

Hi Dick, just wanted to let you know that the radio I'm using is a radio shack pro-2045 and the antenna I'm using is a grove scanner beam and have it pointed directly at Tampa International, I have no problem listening all the approach and departure and tower frequencies. my concern is with San Francisco radio there are 3 repeater sites if that what you want to call them. one is at MIA Int, TIA int, and JAX int. from what I was told on how it works is when an airline is in range they dial the number to San Francisco an it transmits on 131.175 and it broadcasted on that frequency and is relayed via landline to San Francisco and it is used for phone patch and is used to pass information to there company. hope this makes sense. what I'm trying to find out is where the transmitter site is located and what height it's at and how much power there using I just can't seem to find that information, only thing I could find was the frequencies at TIA and the different company frequencies.

Are you talking about San Francisco, CALIFORNIA? If so, it is not possible to hear 131.175 in Tampa, FLORIDA from there.

Its a telephone relay..it is possible and AIRINC operates many of these.

Allen,

If you don't already have it, here is the ARINC Domestic VHF coverage map:

It's showing Tampa, Jacksonville, Miami and Pensacola as TX sites for 131.170 MHz

Now that makes a little more sense. Thanks.
BTW, is there a list of those relays someplace?

I want to thank datainmotion & nd5y for all your help this really helps out a lot, I see that I'm only 28 miles from the transmit site and wow since I raised my antenna height to 60 feet now everything comes in clear now. again thank you everyone for all your help.
