Understanding the FCC'S Website

[cookiend15]

Hello fellow scanners. Today I learned that on the FCC's website if there is the term FB2 next to a frequency under Station Class it means that that frequency is the repeater frequency. Could someone please help understand what the other terms mean under Station Class such as FB, MO, FX1, ETC. If you can identify for me what these terms mean that would be great, and also if you could let me know if you know the meaning on any other Station Class identifiers I might find on the FCC's website.

Also 1 more question. With the fact in mind that FB2 under Station Class means repeater, how would you figure out the following for callsign KZB383 Montgomery County Sheriff.

39.460 FB
154.710 MO
154.785 FB
154.785 FB2
154.785 MO
155.370 FB
155.370 MO
155.625 MO
155.670 FB
155.670 FB2
156.090 MO

Now I know that 154.785 FB2 and 155.670 FB2 are repeaters, but how do you know what there are repeaters for meaning how do you know which of the above frequencies is there input frequency. What I'am trying to do is understand more about repeaters since a repeater is all that you will need to program into your scanner and you will not miss any of the action. So looking at this and knowing 154.785 and 155.670 are repeaters how would you figure out what there respective input frequencies are.

Thank you for any help to my question.

The only way you find out what input goes with what repeater is to listen and find out. The FCC records don't show that.

FB is Fixed Base, MO is Mobile.

Sometimes, you can make a guess based on number of mobile units on a channel, when the system has different numbers of them set up on different channels, but this particular system doesn't.

You can't even always assume that the input can be ignored in listening, since some systems use the input as a simplex channel, by turning off the CTCSS so it doesn't trigger the repeater.

Remember that from 450-470 MHz, inputs are 5 MHz up from the output. From 470-512 MHz, inputs are 3 MHz up from the output. There's no standard for VHF, sadly.

The input will be one of the MO frequencies.

Try the General Menu Cue Cards, they explain every code you will find in the database. You would be amazed at the wealth of knowledge you will find in the help files!
