8 GMRS Repeater Channels

 I get what you’re saying but it is fairly common (really common) for people who are new to GMRS to not realize they are in fact different and try and change all their settings to make the simplex channels talk to a repeaters when they’re not grasping the concept. I think @SteveShannon is just trying to avoid putting out info that is confusing and point out what may be obvious to some to those that don’t know.

It might seem pedantic, but if you’re on channel 19 on a 95E certified radios, you can’t transmit to the repeater.  If you can’t transmit to the repeater it’s not a repeater channel. 

Okay, I can see why using channel 19 and the repeater channel (however the manufacturer has labeled it) interchangeably could be confusing to some people.

What?  It's a simplex channel because transmit and receive are the same frequency (no offset). Normal repeaters require the offset but there is a thing called simplex repeater too.  And there's nothing in the regs that prevents fixed stations from transmitting on 467 simplex if your radio lets you.

That's interesting. It doesn't mention fixed stations. Not that it means anything for most of us, because we're unlikely to be operating a station that communicates only with other fixed stations.

§ 95.1763 GMRS channels.

The GMRS is allotted 30 channels—16 main channels and 14 interstitial channels. GMRS stations may transmit on any of the channels as indicated below.

(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.

Out of curiosity, has anyone here seen a true fixed station in operation? What was its purpose?

Nope!  This is what my copy says:

(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.

 

Notice that fixed is not included in the restriction to repeater use.  (Fixed stations aren't allowed to use repeaters so that makes sense.)

You're right. I skipped right over the part where you were only talking about fixed stations.

Search for threads with Fixed Station in the title.  There are a couple and they are multiple pages trying to address this.

Read section C. These are the repeater main 467 channels. Fixed stations I believe are primarily for equipment control and not for normal  communications. This would make sense since the 467 main channel frequencies are the repeater inputs, which can also receive control commands from a fixed station.
