Repeater Question

[cohenner5377]

Is it possible to have more than one frequency on a repeater? I know they have to be on the same band. We are looking at putting a second frequency on the repeater that we already have, however, the radios that are being used will have a frequency on a second repeater as well.

To answer your question, Yes and No.

By that I mean the radio can have multiple frequencies, but the repeater system
won't work very well with a second channel. Reason for this is that most repeaters
have a duplexer or filter system to keep the transmitter from causing interference
to the receiver. This filter system is very frequency sensitive. Moving just a
channel or so each side of where they are tuned will cause problems.

The 2nd frequency need not be on the same band, if you are talking about a ham repeater. It's done very frequently - numerous systems have links on 2, 220 450 even the 6 and 10 meter band. The BRATS repeater system in our area is a case in point. It has a 450 system which is linked to 147.03

Two frequencies, two repeaters. You need a reciever on the new channel (your current one is busy listening to the original channel), and you need a transmitter for the new channel (your old transmitter is busy transmitting on the old channel).

Oh, if you want to junk the entire system, radios, repeater, and all, you could get a new system with multiple 'channels' on one actual rf channel, CDMA/TDMA style, but I don't think you want to do that. <grin>

You can have one repeater linked to multiple transmitters and receivers, yes, but you don't get seperate channels that way. You get everything mashed onto one channel. What do you actually want to do?

David if you don't mind me butting in here....

He already has one frequency on one repeater. He has that freq split into two channel using two different Pl Tones. This is all off of the same repeater. He wants to know if it would be possible to add another frequency and have that repeaterized (Is that a word?lol) as well using the same repeater/equipment.

Thanks all for your answers. Mo is familiar with the question, and summed it up properly...

With the right setup, the antenna(s) can be shared, but everything else will need to be duplicated.

One possible way to do it is to use the Motorola F1/F2 scheme. This is assuming, of course, that your console supports this. If you don't have duplexers or combiners on the repeater, this might work for you.
The advantage of this is cost. The disadvantage is if the repeater is in F2 mode, you can't hear calls on F1 and visa versa.
