If you look at the FCC license, you will often see a number of frequencies listed.

You will see one, or more marked as FBx, where x = a number. That is the repeater output.
You will likely see another frequency marked as MO, which is usually the mobile transmit frequency, or the repeater input.
Sometimes there may be more than one MO frequency, sometimes for talk around, sometimes for simplex use, but usually there will be one for the repeater input.
Sometimes the MO frequencies can be under a different license.

UHF band plan is often 5 MHz offset. 800MHz is often 45MHz offset.
VHF, all bets are off, usually. There was never really any standard for the LMR users on VHF.

And don't miss this "sneaky" UHF offset change when you go above 470 mHz.
Buried in the middle of that list is the UHF T-band offset of 3Mhz, which you'll find operating only in a few metro areas between 470 and 512 mHz.
