Repeater Number Question

[WRKY933]

When making a channel chart there are some repeaters that have numbers such as Repeater 1 thru 7. What differentiates these repeaters. Are certain frequency range blocks assigned to certain repeater numbers? Does a number 3 repeater get a certain frequency range compared to a number 7 repeater? How does that work?

I just saw a video on the Youtube that explains this exact question:

Eight frequencies have been designated in regulations for repeaters to transmit upon.  They are the same eight frequencies used by both FRS and GMRS for simplex communications and they are numbers 15-22 in the FRS regulations:

(a) 462 MHz main channels. Only mobile, hand-held portable, repeater, base and fixed stations may transmit on these 8 channels. The channel center frequencies are: 462.5500, 462.5750, 462.6000, 462.6250, 462.6500, 462.6750, 462.7000, and 462.7250 MHz.

Eight other frequencies, 5 MHz higher in frequency, have been designated by regulation for transmission by stations wishing to transmit to a repeater for relay by the repeater:

(c) 467 MHz main channels. Only mobile, hand-held portable, control and fixed stations may transmit on these 8 channels. Mobile, hand-held portable and control stations may transmit on these channels only when communicating through a repeater station or making brief test transmissions in accordance with § 95.319(c). The channel center frequencies are: 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750, 467.7000, and 467.7250 MHz.

All GMRS certified radios pair the eight channels in those two groups into repeater pairs.  Thus, a radio transmitting to a repeater on 467.5500 MHz receives from that same repeater on 462.5500 MHz.

The FCC did not assign channel numbers to the repeater pairs in the GMRS regulations, but they did assign numbers to the first 22 channels in the FRS regulations https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-B

Because channels 15-22 (462 MHz main channels) are dual purpose, as shared simplex channels for FRS and GMRS and as repeater output channels, some manufacturers refer to the repeater pairs as RP15 - RP22.  Others simply continue the numbering sequence by referring to the repeater pairs as channels 23-30.  Other call them repeater channels 1-8.  The best thing to do is to be aware of the frequencies allocated in regulation and learn what your radio manufacturer calls them.

Much simpler than my explanation.  Good job!

Thanks Steve, that info helps.

Meaning they are there, as part of the frequency allocation, but are NOT to be used for general simplex communications without communicating through a repeater.

So they are extra channels how?  Regulations say they can't be used for simplex operation, so they really aren't for general use.

Non-boolickers say they don't care what regulations say.

OK, so yet another video about nothing,,, getting posted on here to get clicks and get you paid. 

Of course, content of the video.  Especially one that is controversial, gets you more clicks and therefore more paid.  Never mind that the regulations specify you can't use the channels.  Rules are for bootlickers right?  Nevermind that your efforts and video's were quite possibly a part of what got the FCC to do an about face on linking and shut all that down.  So the rules only apply when they make YOU money.  Maybe someone at the FCC needs to look into how you are cashing in on spreading misinformation.  Maybe they will come down on you like they did the guy from Info Wars.  Hard to tell.  

 

How's that AI chat bot working out for you?

I was going to respond, but its starting to feel like i'm bullying the kid in the wheelchair at school.

WTF??? My sons confined to a wheelchair... you asshole, what kind of bullshit is that?  You implying something here? 

Keep running your mouth about my kid.  I knew you were a jackass, but now your bringing my son into this.  Who the hell do you think you are?

it wasn't about your kid, it was about you. It was about me starting to feel bad about arguing with you because all you do is make yourself look like a fool, and it's too easy to make fun of you.

At least you didn't start a fight with your response.
