[Repeater-Builder] Re: GMRS Repeater Project Progress
I now have a Pass/Reject Duplexer Coming To me for my GMRS Project. A nice guy from the forums here is swapping one to me for my LPB 8ch mono broadcast board. but due to the fact i may be moving to alabama soon, it will be official on dec. 1st. the repeater obviously will not be in the hunterdon county area now. I will be going to City of Tuscaloosa in alabama so i will be searching for a free host in that area. Guess having a Pass/Reject Duplexer will now allow me to colo the repeater on a tower site.

Re: [Repeater-Builder] Re: Gmrs Repeater
The GMRS full power channels are 462.550, 462.575, 462.600, 462.625, 462.650, 462.675, 462.700, 462.725. Deviation is +\- 5KHz. Power output 50 watts + antenna gain, if any. The interstitle channels like 462.5625 are used by the FRS kiddie-talkies. 500mW power, +\- 2.5KHz deviation, no external antennas. Whoever thought that arrangement up had no comprehension of how a radio works. If I were going to try to use GMRS today with the prolifiration of kiddie-talkies out there I would limit my receive radio bandwidth to the 12.5K setting to cut down on the adjacent channel junk, but that means that any radio normally set for GMRS at 25KHz bandwidth will sound crappy.

Re: [Repeater-Builder] Re: Gmrs Repeater
Gary, A mobile relay station is defined as a device that relays mobile traffic (i.e., a repeater). A fixed station is simply a base station, at a fixed location, manually controlled by an operator. This is standard across FCC controlled communications and is not GMRS specific. LMR repeaters are commonly licensed with a station class of FB2, which the FCC designates as mobile relay. A fixed base station would be classified as FB under an FCC license. When a system will have a fixed base operating through a repeater you'll have both FB and FB2 on the license.

Re: [Repeater-Builder] Re: Gmrs Repeater
I wrote NARROWER GMRS SPECS. I did not write narrowband.

Re: [Repeater-Builder] Re: Gmrs Repeater
Thanks for that background info. I suppose that's one way to look at it but in my experience a mobile relay station now carries a different definition from the FCC as shown in Part 90.7 for example. They also define a fixed relay station so while at one time the term 'mobile relay station' may have passed as any repeater I wonder if they take a different position today.

Re: [Repeater-Builder] Re: Gmrs Repeater
Narrow band is only required on the interstitial channels (those that fall between the repeater pairs) along with the reduced power requirements, but I don't believe the FCC would have any problem if were were to narrow band a repeater. However transient users and other may have a problem ,radio wise, in using it unless it is a private or closed system. -- Doug N3DAB/WPRX486/WPJL709 [EMAIL PROTECTED] wrote: = Good idea Richard especially since Mitreks are wideband radios so making them meet the narrower GMRS specs is probably a monumental task. I wonder if a Mitrek can even meet the required frequency tolerance. Gary Richard Bessey [EMAIL PROTECTED] wrote: Hello, I just wanted to add my 2 cents here. I have been working the last ... 2 years on building a GMRS repeater out of two Motorola Mitrek's and a single M controller. If I had one word of advice, buy a commercial one! Save yourself alot of frustration and money on the tools needed to build it.

[Repeater-Builder] Re: Gmrs Repeater
This in response to shady1070's original question and Gary's reponse. Unless I've been misinformed for the past 30+ years the maximum autorized output power for GMRS is 50 watts from the Xmtr.(Base, Mobile and Repeater). There are power limitations on the interstitial freqs. but Repeaters are only permitted on the 8 designated pair $62/467.550 thu .725 in 25 KHz steps. Re: the original question about the rptr./controller set up I would suggest the Kenwood TKR-850 which has everything in one package Contoller, CWid, ctcss/dcs, computer programable, etc. and the Kenwood can be reprogammed down to the 440 band. GMRS rptrs. are not REQUIRED to ID, the GMRS user is, however if the all users operate under a single authorization/call sign CWid is allowed.

A repeater is a mobile relay station, not a fixed station as defined in the rules. 50 watts is the limit. thp Gary wrote: CFR title 47 is available on the FCC's website for all to view. 95.135(a) reads No station may transmit with more than 50 watts output power.
