The problem with this is you can have two people with different codes talking over the top of the other person because he didn't know the other guy was there. FM radio uses what's called "capture effect". The strongest signal captures the receiver and the coded station won't even be heard. How about 19 for TJ Fest, 21 for Team Coco, and 22 for Team LJ, 16 for Group A, 17 for group B, etc. We would all use the same DCS code for ease of memory and just use the "trucker channel" when the group gets back into town etc?
For those who don't know, the DCS (digital coded squelch) code will only allow you to hear other people who are transmitting that code, even if they are on the same frequency. Motorola called it "Private Line" (hence PL Tone) back in the day when they used analog tones instead of digital codes. Your radios will be programmed with the normal uncoded GMRS channels, and then special channels named Coco or LJ or TJFEST with the proper code preprogrammed in with the channel of choice. People without the tones will still be able to hear you, they just can't talk back to you.
I hope our groups don't get much larger than 10 rigs each or its going to be a LONG DAY on the trail! Are there other Moab veterans willing to step up and lead groups? I've been finalizing draft #1 of the 16 trails Team LJ will be running from Saturday to Friday. It may need whittling down; we'll see!
That makes sense, since @bobthetj03 is right, let’s do this:
Group | GMRS Ch (freq) | DCS | CB Channel |
TJFest | 16 (462.575) | D223N | |
Hyphens (CO) | 17 (462.600) | D223N | 30 |
LJs | 18 (462.625) | D223N | |
... | 19 (462.650) | D223N | |
... | 21 (462.700) | D223N |
Here's a good list of how to configure radios to use DCS: https://www.sfarc.org/dcs-instructions.html
Here is my CHIRP settings that you can upload to a Baofeng UV-5r (this will be continuously updated): https://drive.google.com/drive/u/0/folders/1l00DDHX-qdFv1AxD4U65lTMwfU148OdC
Unless there’s any reason that doesn’t work, I’ll bug Chris to get it in the main TJ Fest post.
