Does anyone know if the spectrum between 476-477 Mhz is occupied by anyone in this state? It can help me determine interference with possibly purchased radios.

Never mind

I found what I needed. 470-476 Mhz is analog TV channel 14, a station in Rome, Georgia. Now it is DTV channel 51, 692-698 Mhz (I think). Anyway, according to the Library in Monitoring Times Mag., under the Public Safety Pool, That range ( all the way to 512 mhz in the "T" Band ), can be allocated to public service, of which locally I don't yet know who 470-476 Mhz is allocated to.

In the days before we switched to digital TV, if there was a channel 17 in the area, that band was closed down. Now that digital is in the picture, I don't know why it hasn't be opened up.

Band Opening?

By what exactly do you mean?

The frequency that 17 broadcast on in analog is different from what the frequency that 17 digital is broadcasting on.

Yes, I know, but...

...what's a band opening got to do with this, B?

Anyhow, it wold have been more an issue with Channel 14, in Rome, Ga., than with TBS/Peachtree tv .

You can query the FCC Database, but from 470-480 MHz you won't find anything there except WRBL out of Columbus, WD9XZY a tempy station for the PGA and WE2XLC a experimental station for Georgia Tech.

That's good news...

Do you know if there are any specific Public Service Personel that are assigned to that spectrum? (470-477MHZ}

If they are, they are unlicensed. A lot of times if you hear anyone up on those frequencies, it's usually the IF of the radio causing it. i.e. If your radio has an IF of 10.7, double that number to 21.4 and subtract it from the frequency - 474.850 subtract 21.4 equals 453.450. Punch in 453.450 and you will most likely find the same transmission.
