GMRS regulations spreadsheet

[davidotoole]

While reviewing the GMRS and FRS rules for my project I made a spreadsheet with all the relevant regulations so that I can see everything at a glance. I thought I would post it here in case anyone finds it useful, although I cannot promise that there are no errors. Perhaps someone knowledgeable could look it over and correct me! If you have time.

Here is an ODS version of the document.

Two things, came up my mind, you want to add to list

- Channels 8-14 to hand-held radios only

- Digital/data transmission is limited to 1 seconds not frequent than 30 seconds

Thank you so much! I have added them I'll post a final version a bit later if anyone else has suggestions or corrections.

There are few things related with antenna height at https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-A/section-95.317

Hi everyone, I've updated the spreadsheet (see attachment) with just about everything I've been able to find. I hope you find it useful.

You’ve obviously gone to a lot of effort.  I commend you for that.

Personally, though, I just refer to the actual regulations here: https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95

Or for just GMRS: https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95#subpart-E

Thank you. I dunno I just like having all the operational regulations on one easy to read (sort of) page.

This is super-useful!  Do you mind if folks distribute it?

I'm trying to set up a local group too....

Sure, go ahead. I'd like to give you Excel, ODF, and CSV formats as well so that you can modify or convert it.

@Blaise I wish you the best for your group. I have put up our new web page here: Trails Adventure Team perhaps there will be useful information and ideas.

I don’t have an aversion to diving into the actual regs but this is very clear, basic and well laid out and I feel this would be great to hand to someone with no knowledge of the service as well as great reference material. Nice job and thanks for the download.

I agree. I must have been feeling churlish the other day. The document is an excellent and concise reference to the regulations. I apologize for not being more positive.

A lot of radio manufacturers have made small errors on channel spacing especially on the BTECH GMRS PRO. It's impossible to get Channels 1 through 7 and 15 through 22 on 20.0khz. They will only do 25.0khz. which technically is off by 5khz from what I see in the FCC Part 95E. Channels 8 through 14 are the ones that meet FCC requirements for narrow band.

small errors on channel spacing

Channel spacing and occupied bandwidth are different things. On narrowband channels, spacing is 12.5 KHz, while occupied bandwidth is usually 11 KHz and even less on some chinese radios. On wideband channels spacing is 25 kHz, while bandwidth is 20 kHz, and on many radios is actually 16 kHz. This is how interstitial channels fit (barely).
