I recently installed an AT-778 in my FJ Cruiser, as you can see, it has all of the controls on the mic.

Here's a few to scan through. https://www.theantennafarm.com/catalog/index.php?main_page=index&cPath=191_193_258_977_978

Not the same Midland as in grandpas' day.

I was at my Ham Radio coffee break last night. One of the topics for discussion concerned a local CB operator running hugely excessive power. The interference was so bad that a nearby hospital had the FCC track down the source because it was buggering up some of the heart monitors they used on patients causing them to malfunction.

I just wanted to add to the conversation a little nugget. We talk about the need for type certified radios and what that means for manufacturers. Some figure that if a manufacturer allows, through official software or other means, a radio to do something outside its certification then that’s ok. What is not talked about is one’s obligation, per the rules, as a GMRS licensee. This obligation is to operate fully within the rules. Much like an amateur license where the burden is placed on the amateur to make user they operate with power and frequency limits, so too does the GMRS licensee assume a similar burden. If the FCC were to get pissy, and decided to make an example of someone, they could not only go after a manufacturer for some form of non-compliance, but also licensee for knowingly using hardware in a manner inconsistent with the rules. Even something as simple as operating at more then 1/2w ERP on the 467 interstitials, operating simplex on 467 main channels, or using a non-certified radio in GMRS. While some might argue “the manufacturer’s product allowed me to do it” so it must be ok. But ultimately responsibility exists on both sides. The licensee agreed to the rules when then they applied for and where granted their license. Just like the FCC appears to be unwilling and powerless to go after the manufacturers for skirting the rules, so too are they not likely to come down on the user. My point being, licensee responsibility is equally as important as manufacturer responsibility. Worth mentioning. Michael WRHS965 KE8PLM

Your interpretation is in error. If a radio is type accepted to operate under one section of the regulations then modifying the radio to operate under a different section of the regulations invalidates the original type acceptance because the radio was not tested under the second set of requirements. It doesn't matter if the modification involved hardware and/or software. Any modification that causes the unit to operate outside its accepted parameters requires the radio to be resubmitted for type acceptance. The FCC Rules and Regulations require 7 volumes to contain them all. Reading one portion of one paragraph under one section does not negate the information or requirements found in the entire body of Title 47 of the US Code.

Any change to operation mode invalidates its type acceptance. Same goes for part 90 radios. Doesn't keep people from doing it.

Thank you for that well-designed chart!
