I had a leather case speciality made by Leathersmith and I bolted the case on top of the switch panel. You might be able to see it if you expand on the attached picture of the inside. Depending on where I was racing, I used either VHF of UHF in the Astro 25 Digital mode with an XTS portable. I used a Racing Electronics Harness with a PT-T on the steering wheel and Racing Electronics Helmet Kit with their custom molded ear inserts. Since, the body panels were composite I ran with a non-groundplane Antenex NMO mount antenna on the roof. I never had any coverage problems and my crew were using the Otto Behind-the-head headsets with the remote antenna attached to the headset and a XTS portable. I thought about going with a mobile, but I never saw the need. Although, I have been a GMRS licensees since the mid-90s, I never used any GMRS freqs. I used Part 90 freqs I was licensed for in both the VHF and UHF bands.

Shaw Butte and the two Towers repeaters are still down this morning.

You asked for 95E radios. At one time or still do Motorola did/do offer a FRS radio that had a removable antenna, thus has to be a 95E type-accepted. Those radios were only 2 watts. Some of the Cobra radios have removable antennae and have to be 95E Type-Accepted. I'm not sure if those radios are only 2 watts or 5 watt radios. Just because a radio is made in China doesn't make them a China radio. Midland, Cobra, and Motorola are an American Owned Company and they design/engineer the radios right here in the United States and outsource the building of those radios to a company in China and have them built to those specifications.

Midland, Cobra, and Motorola.

18-10 could either be either 462.625 MHz/94.8 Hz or 462.625 MHz/D065N. That will depend on if the tone/code setting is either set for analog or digital. You would need to enter in the menu in order to determine the setting. Also, there is a menu procedure to toggle between the actual tone freq and DCS binary code, and the radio tone/code programming code settings. Don't expect this radio to work optimum from inside the vehicle with a range of no more than a quarter to half mile. For decent trail comm on GMRS freqs, it would be best to install something at least a Midland MXT500 or MXT575 with a Midland NMO mount MXTA25 (Phantom) or MXTA26 6 dB antenna.

Thank God that the closest affected repeater is 425 air miles, twice the distance of his 200 mile range capability from Phelan, I would think we would be well out of range especially with a hill or two in between the two points. Although, the two Crown King repeaters are at 7,800 feet in elevation, I guess there may be a slight possibility only for his radio.

You will need to use two antennae, one for the 70cm freqs and one for GMRS. You should mount each antenna on the side of each cowl near the "A" Pillar using the Rugged Radios mounting brackets and NMO mounts. Don't use the cheap stuff get the Laird Mount and Cable from a reputable Radio Electronics Dealer. As for the GMRS antenna since it appears you are only concerned with GMRS for the trail, you should get thd Midland MXTA25 or the MXTA26. Attached is a picture of my Highband VHF antenna on the side near the cowl and "A" Pillar. Also attached is a Laird Lip Mount NMO mount I use for my UHF DMR freqs. The Phantom antenna is a Laird. Just make sure that the mounts have chassis ground continuity without the coax cable connected to the radio.

I would say that the radio took a dump. The radio should not be 200 degrees unless you kept it keyed for an extremely long time.

For citizens using radios in a foreign country, you should contact the United States Embassy and ask them that question. In some countries, Personal and Business Radio Services freqs may not be used for the same radio services in the other countries. The Amateur Radio freqs might be a different story. I'm not as smart as an Amateur Radio Operator, so I don't how that works in other countries regarding HAM freqs. For governments visiting and using radios in foreign countries, I had to contact the United States Embassy Regional Security Officer (RSO) in that respective country and get a channel assignment from the ITAC800 Channel pool.

That is not unusual for Pandaland radios to sound like a popcorn popper. Real non-Pandaland radios don't have that problem.

At the moment, I can only hit 550 Alpha and Sun City West 625. I usually have no problem hitting Shaw Butte, Towers 575 & 600, but not today. I suspect the problem child is back at it since Shaw Butte, and the two Towers repeaters are down.

The original post said you want to find a way to edit the firmware so your MXT500 can transmit on 463.200 Megs and receive on 462.700 Megs as a channel pair. 463.200 is a Business Radio Service freq in the Part 90.35 subpart C in the Business/Industrial Pool. You can not do that legally with that radio and you need a Radio Station Authorization to transmit on 463.200 Megs

I don't believe anyone has edited the firmware to push beyond the GMRS operating band range of the MXT500 radio. In most cases, It would be easier and cheaper just to acquire a Part 90 radio such as a Kenwood TK880 or TK8180 radio.

When it comes to radio electronics nothing is impossible as long as you have the funds and the know how. It is really basically manipulating electrons and passing audio from one device to another device. Crossbanding in-band and out-of-band multiple radio devices can be accomplished in several ways, audio tie with a logic controller, voting comparator using COR, console patch, or an interoperability gateway. I've designed several crossband package configurations back in the 70s, 80s, and early 90s and some of them have been written up in various trade magazines. Back in the early 80s, I designed an airborne repeater package using a GE Porta-Mobile II Low-Band Radio and a GE MPD Portable with a Sweet Electronics Logic Controller and put it in an Airplane so two vehicles (car on a VHF Highband Channel and a motorcycle on a Lowband VHF) can directly communicate over 15-20 miles apart in hilly terrain while in motion traveling across the State for a special event. "Some People" not in the know couldn't figure how in the hell I was able to make a Lowband radio talk directly to a Highband radio. My answer to them was "I used the "PFM" technology method. I truly missed those days creating solutions like this to make the impossible possible.

The MXT500 programming software requires Windows 10 or 11 OS.

I actually have been in that station a few times.

I drove by the Station in Carson everyday I was working that was used as Station 51 in both the pilot and the weekly episodes. I don't remember the actual Station Number.

I'm sure the Danish Pebbles guy won't get it! He probably doesn't watch reruns on ME TV

You mean like the cool people that sign-off with "KMG365"?

I believe the Rasberry Pi thing was also used back in the linking days to interface with the Internet.

Emergency Maritime Channel in the Maritime VHF Band is channel 16, also used for safety and common calling, per Part 80 Rules & Regs. The use of channel 16 is regulated by rule and does not require a station or individual license while operating on-board a vessel or in port. No, the use of the Part 80 freqs cannot be used on hiking trails and even for your land yachts.

Huh, is there any possibility that you can explain what you are trying to convey? I'm kinda less than a bright person and I am not a college boy and I barely got my high school diploma and I had to go to summer school to get the diploma. So, what the hell are you trying to say? What regulation are you referring to?

I knew that when I wrote my response, I just didn't convey it correctly. In a rush while I was waiting for my last Physical Therapy session, I counted my multiplication factor of the 4 watts as the number of dBs with my fingers rather than the total dBs. That is what I get for rushing myself and using an android device.

....penetration....penetration with or without lubrication, it won't change the price of noodles in Pandaland

It really makes no difference if the tests are done in the car or building or outside the car of the building insofar as testing the differences. The signal level differences between the two test sample power levels won't be changed by any measurable amount between the two signals. Yes, outside will get you more farz for both power levels. In my case with a difference of between 4 watts and 60 watts, it is still a tad less than 4 dBs and that difference of less than 4 dBs of signal level won't change rather if you are outside or inside. You still need to deal with the signal-to-noise ratio.
