John,
That (GMRS License) would be a bit difficult for Mattos – he’s in Brazil… Mark – N9WYS From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Maire-Radios Sent: Saturday, November 15, 2008 2:57 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] 900mhz , DTR, 906 to 923.75 MHz FHSS ? 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.

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 (RF) 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. Technical Specifications Smartamp Features: 10 Watt Operating Range: 902 - 928 MHz Operating Mode: Bi-directional, TDD Transmit Gain: 28 dB (can be customized to 33dB) Frequency Response: ± 0.75 dB over operating range Output Power: 10 Watt (+40 dBm) nominal TX Input Power: 500mW Receiver Gain: 12 dB typical ±1 dB Noise Figure: 3.5 dB typical Connectors: N-type, female, 50 Ohm Lightning Protection: Quarter Wave Technology DC Surge Protection: Available Power Consumption: <2A @ 12-15 VDC (100% duty cycle) Operating Temperature: Amplifier: -30 °C to + 70 °C 15V DC injector: -30 °C to + 70 °C will work in this way? or anyone knows a repeater for this digital radios(cheap please) Thanks Mattos No virus found in this incoming message.
