General Repeater Question

[zerowatts]

I don't where to post this question so for the sake of simplicity I will say I am talking about GMRS frequencies.

If I have 3 people on a GMRS frequency, and I want all 3 radios to be on the primary frequency with the same CTCSS, each radio scan a secondary channel (same frequency different CTCSS codes) this in lay terms would give all three radios a private line so to say. In a simplex operation this is no issue at all but in a repeater style setup, ideally each CTCSS 'talkgroup' would have to have their own TX/RX radios (on the repeater end) in order to not get frequency busy signals back correct?

In simpler terms does a repeater need to have one radio per CTCSS talkgroup?

If you're only using one frequency pair for the repeater, then you're going to run into problems, i.e., users transmitting at the same time as another because they didn't unmute their radio to make sure that frequency was clear.

You can buy repeater controllers that will do multiple CTCSS tones, so there is no need for three repeaters. Plus if you put three repeaters all on the same frequency pair, you would just hear a lot of garbled crap.

So that's what the controllers are for!!! Thank you! How many can these controllers handle? Is this how so many companies can share the same frequencies in bigger cities?
