Retevis Repeater

[WRXP873]

Need help locating instructions on how to program my RT97S repeater. My searches haven't helped. I have the software but afraid to change anything without any instructions/how to's.

The channel I want to use is not  programmed in.  462.5625

Thanx, from a newbie+

The first thing you should do is familiarize yourself with the regulations. Repeaters may only transmit on eight frequencies and 462.5625 MHz is not one of them. 

(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.

I'm not understanding, the book says Channel 1 is 462.5625 , is that freq for simplex,  radio to radio or base only?  Only freq for repeaters is the 8 you mentioned?  Thanx for the help.

GMRS has 22 Simplex channels (Radio to Radio) 1-22. It has 8 repeater channels RP15-Rp22. The first repeater channel available is 462.5500.

This chart is helpful to be able to see it.

Got it, TY!  A friend says you can use repeaters on any channel. I'll take his advice & verify it from now on.

From the regulations:

(b) 462 MHz interstitial channels. Only mobile, hand-held portable and base stations may transmit on these 7 channels. The channel center frequencies are: 462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875, and 462.7125 MHz.

Not only that, but they are limited in power:

(b) 462 MHz interstitial channels. The effective radiated power (ERP) of mobile, hand-held portable and base stations transmitting on the 462 MHz interstitial channels must not exceed 5 Watts.

Also, for a repeater to function in fill duplex, they listen on one frequency and transmit on another. The offset is 5 MHz, so, your radio would have to transmit to the repeater on a 467 MHz channel. On 462.5625 MHz you’re only allowed half a watt:

(c) 467 MHz interstitial channels. The effective radiated power (ERP) of hand-held portable units transmitting on the 467 MHz interstitial channels must not exceed 0.5 Watt. Each GMRS transmitter type capable of transmitting on these channels must be designed such that the ERP does not exceed 0.5 Watt.

My suggestion again is to read and understand the regulations. The radio you have was programmed to follow the rules.
