Member Benefits

#1 • CAVERN Member Benefits Package

As the 2020 fire season draws to a (hopefully quick) close, it gives us all time to participate in a discussion about public safety and radios around Cobb Mountain. Especially relevant —while things are fresh in our minds after a few nearby fires recently grew into the first “gigafire”— is what have we all learned we still need to do?

An idea has been floated on the CAVERN Talk list to bundle different PDF information sheets together into a CAVERN Member… Booklet? …Package? As a benefit of being a CAVERN volunteer/member, you get the collected wisdom of the Community assembled in one convenient PDF package that you can print pages from for your refrigerator or bulletin board.

What pages/chapters/sections/etc do you members of the CAVERN community think the Member materials package should contain? Is a PDF file enough? Should we also organize things like bumper-stickers, tee shirts, lawn signs, etc?

Here are a few Example Ideas:
 + CAVERN Channel Guide (1pg Guide/128 channels/Printable)
 + CAVERN Member DB (Members’ firstname+callsign/all 6 Groups)
 + User Guide for <my radio model> (1pg/Printable)
 + GMRS Licensing Guide (upgrade FRS/listen to GMRS/talk)
 + Emergency Radio Instructions (what to do/emergency radio stuff)
 + Pandemic Radio Guide (radios & public health)
 + Network Control Script (what I read if I need to lead)
 — Anything else to add, Cobblers?

Please make your suggestions in a Comment (below).

#2HELP

PLEASE, WILL YOU HELP assemble any of these 1-page documents, using information already available on the https://CAVERN.mobi website?

#3 • PARTICIPATE

CAVERN has three low-volume mailing lists at lists.CAVERN.mobi

(1) The most basic is “Announcements” which sends out general CAVERN info (meetings, news, etc) 1-3 times a month.

(2) Next is “Alerts” which ONLY broadcasts urgent emergency info like evacuations, ongoing fire threats, power outages, sudden lightning storms, etc. If things are going well, you’ll almost never get anything from Alerts, but you have to be subscribed to get the important stuff!

(3) Last but not least is “Talk“, the general conversation list to which any subscriber can post their information, questions or advice. If you have a CAVERN radio, but you’re NOT on the “Talk” mailing list yet,
just click here to become part of the conversation.

Q: What is GMRS?

A: GMRS stands for General Mobile Radio Service, and is a medium-power 22 + 8 (repeater) channel two-way radio service in the UHF 462/467 MHz range. Shares same frequencies with FRS.


Q: Is CAVERN Channel 8 or 9, 15, 23 or what?

A: All of the above! CAVERN is heard on 462.550 MHz which is GMRS/FRS Channel 15, however different radios access this channel via different channel locations. CAVERN-programmed RETEVIS RT22 hear.

Q: Why can’t people hear me?

CAVERN Channels

CAVERN’s preprogrammed Retevis RT 22 radios channels match the way most FRS/GMRS radios are programmed, but only for the first few channels. This is because the RT22 only has 16 channels and cannot transmit at the legally required 0.5 Watts for FRS channels 8-14 (so we left those out for now).

What this means in practical terms is that on CAVERN pre–programmed FRS radios (e.g. the “Retevis RT22”), Channels 1-7 correspond to most off-the-shelf FRS radios, HOWEVER: CAVERN’s Channels 8-16 are NOT programmed to the standard frequencies and tones.

This table below shows: pre-programmed CAVERN channel locations (in the first column); the corresponding normal “Standard” FRS and GMRS channel location for most non-CAVERN radios (i.e. the “factory settings”) and; additional CAVERN frequency & tone settings for radios (i.e. to help limit Main Repeater access to Cobb Area volunteers):
