2 GRMS Repeaters on the Same Frequency.

[Mrsig]

I don't need to be told about the law with the FCC please.

Would 2 GRMS (RT97L)repeaters work if they where about 4 miles apart and both set on the same frequency like 462.6000 tone 100.0.

We are looking to extend our coverage in the dense woods and maybe our range.

Thanks for your help.

Would they "work"?: YES

Would they "work" the way you want/the way you are wishing they would to extend each other's coverage?: NO

A repeater can't "repeat" to another repeater, because the output frequency from one repeater (462) won't match the input frequency (467) of the other repeater.

Obviously, they need to be linked.

How would I link them?

Sorry, I was just joking around. The FCC recently made clear that linking GMRS stations over the Internet was against the regs.

And yet, there is a group near me that has almost 20 repeaters linked to the 'net...and even have a zello channel. I'm beginning to think that the FCC's doesn't really enforce anything.

Its cute that it's taken you this long to realize this fact.

They probably respond to complaints, and they aren't getting any.

Okay, they eventually sometimes maybe respond, but don't count on it.

[Mrsig]

Can any one tell me how to link them?

I don't know if you can still download GMRS Live or not. I know the website is still up but for information only. It is basically a GMRS version of Allstar Link.

GMRS Live pretty much shut everything down on their website when the FCC stated that linking GMRS repeaters was verboten.

IF it was me, I would run both repeaters on a different channel if you plan on linking them.

But really, you have two repeaters that are only 4 miles apart in the flattest state in the union and they’re on the same frequency.  They’re going to interfere with each other.  Use just one and get the antenna up another 40 feet.

[WRYZ926]

I have to agree with @SteveShannon on this. You would be better off with a single repeater and use a good quality commercial antenna. The trick is getting the antenna(s) up as high as you can. You should be able to get a 30-50 mile radius of coverage if you can get the antenna(s) up high enough and if the repeater is located on one of the highest points in your area. Hilly terrain and forested areas will cut down on the range if the antennas are not high enough.

I did a search and could not find anywhere to even download the GMRS Live software. So that looks like a bust. The only other option is finding someone that can rewrite the Allstar Link software to work on GMRS. Another issue is if the UHF SA818 module will work well enough on GMRS frequencies. I haven't looked into that myself. 

Again, best is to use a good quality commercial antenna up as high as you can get it with a single repeater.

They shut down.

We know, but you told us that you didn’t need to be told about the FCC rules.
