I wasn’t challenging you specifically but the notion in general.

What would allow an RF signal travel further if it’s AM rather than FM?

And any traffic on those eight repeater pairs also causes congestion on the eight 462 MHz main channels which are the also the fifty-watt simplex channels because they share the same frequencies.
-
@Linuxnut79 - the FCC actually was looking for suggestions for how to simplify regulations. You might want to look into that. Also, having linked repeaters causes congestion locally whilst relying on the internet for greater distances. What happens when the ISPs go down? If you’re truly interested in SHTF long distance radio communications that is designed to survive loss of local services (and overuse of the internet backbone) you should investigate HF.

And people mention Simplex Repeaters, but the official Personal Radio Services definition of a Repeater Station doesn’t support store and forward, which is what a Simplex Repeater does. To add to that the only channels Repeater Stations are allowed to transmit on are the 462 MHz main channels and the only channels that radios may transmit to a repeater are the 467 main, repeater communications are clearly duplex.
-
No, you’re correct, one of the radios would be transmitting on 462, but the other would be transmitting on 467 and not through the repeater.
-
If you read the regulations strictly it’s not allowed. When you’re talking directly to the little lady are you talking through the repeater? When you’re talking to the little lady are you both using Fixed Stations? You might be able to claim that you’re briefly testing… But I don’t think anyone cares. I know I don’t.
-
I don’t think it was an omission. Fixed Stations may only communicate with other Fixed Stations so they cannot communicate through a repeater anyway. Also Fixed Stations are limited to 15 watts. It’s easy for me to imagine a set of Fixed Stations being used as for dedicated family communications between buildings, such as farmhouses and outbuildings on a farm or for irrigation control using DTMF controlled relays.
-
There’s nothing in the regulations that prohibits simplex use on the 467 MHz main channels. They are limited to use for either repeater input, short term testing, OR Fixed Stations, with no mention of simplex or duplex. Others have already posted the regulation, but here it is anyway:
-
Search for threads with Fixed Station in the title. There are a couple and they are multiple pages trying to address this.
-
Tthe Line A restriction no longer exists. I agree with everything else you said.
-
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.
-
15-22 are the simplex channels. 23-30 are repeater channels, but some manufacturers call them RP15-RP22 because the simplex channels receive the same frequencies as the repeater channels. Only the repeater input frequencies (called 467 MHz Main Channels by the regulations) are different because of the offset needed for full duplex.
-
I agree, now that the Line A restrictions have been removed. Marc referred to Randy, of Notarubicon fame, when he used his online name here, @OffRoaderX. Channel 19 is not a repeater channel though.
-
Well, not officially, although tradition probably makes it a more prevalently used tone. it used to be when there was a travel channel, but there no longer is. Here’s Marc Spaz’s far better explanation:
