RE: [Repeater-Builder] GMRS Repeater Info Wanted

I was simply stating that trying to use mobile gear is an inexpensive way to do it. It is NOT illegal as long as the radios are type accepted in the first place, whether mobile or base. If you want to spend a little more money, then buy a Micor or Mastr II base, drop the power level down to 50 watts, and use that instead. GMRS has been around for MANY years. It is NOT a new service. And back in the 80's and early 90's MANY people took regular land mobile bases and mobile units and converted them to GMRS use. It wasnt illegal then and is not now. That is the point I'm trying to make.

Keep in mind that it is your license that is on the line and quite possibly the lives of others who may be put at risk when your kludged up illegal GMRS abortion wipes out some public service station. These are the same kind of people you see driving cars held together with plastic and bailing wire that gets someone hurt or killed. Get the proper equipment to do the job! Please stop recommending this mobile solution,its a bad idea all the way around....

Also Matt, since GMRS is limited to 50 watts, you can use a mobile type duplexer, like a Celwave/RFS 633 series, which I've seen for less than $100 on ebay, and have even seen some around $50. If you can get the mobile radios cheap at a hamfest, and a mobile duplexer cheap, you could probably set up a GMRS machine for less than $200, including crystals, if you use a crystal type radio, since you already have an antenna and hardline.

There is nothing preventing you from using duplexed mobile gear like Micors or Mastr II's, or Motorola Maxtracs/Radius type radios as GMRS repeaters as long as the station ID'ing is handled properly.

Thanks Eric. License I Know is required.  Issue that is at hand, I think you answered, is type of equipment allowed.  I have read issues where guys are building them out of GE and Micor units, and that is what I want to know if this is allowed, or must it be certain types of equipment.  Antenna and cable is already there, 7/8" Andrews and DB 8 Bay antenna, duplexer is something I will purchase after I decide on the repeater.

Before you can put a GMRS repeater on the air, you must have a GMRS
license. You also need to read and understand the applicable FCC Rules
in Title 47 USC Part 95. The current edition of Part 95 is dated
October 1, 2003.

A GMRS repeater should be FCC Type-Accepted for Part 95 operation, but
you can use a repeater that is Type-Accepted for Part 90. This
requirement rules out any repeaters built from parts. Some repeaters
that are relatively inexpensive include the Yaesu VXR-7000, the Kenwood
TKR-850, and the Motorola GR1225 or RKR1225. The important features to
have are a built-in ID-er and the capability to decode CTCSS or CDCSS.
You will quickly learn that a good antenna, duplexer, and feedline cost
more than the repeater.

Although the Part 95 Rules limit GMRS power to 50 watts, there are some
high-powered "pirate" stations operated by unlicensed individuals who
ignore all of the rules. I suggest that you not seek advice from such
people!
