He's in Brazil. I don't think they have GMRS there.

Get yourself a GMRS license and put up a small
462.5 75 to 462.725 repeater and all of your family could use it.

Subject: [Repeater-Builder] 900mhz , DTR, 906 to 923.75 MHz FHSS
Hi all,
I have 2 motorola DTR FHSS 900mhz, and i want to
bild a repeater for use in my farm thats near my store , 5miles.
I know the max watts DTR are 1W, and i didnt find any Repeater or amp for it.
I found 900MHz Smartamp, 10W amp that works on FHSS, so i was wondering,
Can i use a DTR + simplex 40second rec + smartamp + antenna?
Will this amp (its for data) - 12-103 SmartAmp
Bi-Directional 900 MHz: 10 Watt Designed for
extending the range of 900 MHz wireless radio devices, this is particularly
effective when used with Direct Sequence or
Frequency Hopping Spread Spectrum. Full output
power of 10 W is achieved with only 16 mW input to the
amplifier. Above 16 mW input, the SmartAmp
attenuates the input signal power and maintains
the output power typically at 10W. The built-in
dynamic power sensor in SmartAmp adjusts the
Radio Frequency (RFF) power output level by
reading the input signal power. This Automatic
Gain Control (AGC) Technology, Teletronics'
patented technology effectively making the RF
amplifiers "Plug & Play" delivers the maximum
output power at various input levels while keeping the
distortion at a minimum.
