    This is where I mounted my Cobra 25 LTD Classic AM/FM CB Radio in my 23 Wrangler Rubi 2 Dr.

    Thank you. I just had to feed my addiction. I won't have many freqs program except for the Part 90 Business Radio Service freqs I'm licensed for, and the MURS channels for receive only since I can't get radio powered down to 2 watts so I can listen in my travels. The CPS will only allow me to take it to 10 watts.

    I'm just finishing up with a third radio in my 23 Wrangler Rubi 2 Dr. to complement my Motorola XTL5000 High Powered Remote Mount UHF radio and my Cobra 25 LTD Classic AM/FM CB Radio. My third radio is a Motorola XTL2500 Remote Mount 840 Channel VHF radio. I 'm going to use a Laird TE Connectivity B1442 Base Load Non-Groundplane antenna hanging on the driver's side at the cowl with a Rugged Radio mount. I have the radio installed and the electrical connected however, I am waiting on a Powerwerx Anderson Power Pole Distribution Block. I had to remove my CB, Garmin Navigation Systems from the existing distribution block in order to power the newly installed radio. Essentially, all I have left to do, is finished up on the antenna mount grounding system, running the NMO antenna mount cable, install the Mini UHF connector on the cable, and tune the antenna. I intend to do that tomorrow. I called it a day at 3PM Arizona time. I've been out in the garage since 8AM and it was 113 degrees. Then, I will need to program the radio.

    That was it. I never had to do that before but it has been packed up in a house move. Must be out of practice. Thanks!

    I may want to forego this trail so I can keep my fenders on.

  7. There are a lot of different threads with a lot of posts and for the past several months the whole linking subject has been discussed a lot. It’s just impossible to see them all.

    @nokones i have said many times that there is a huge advantage with CB over FRS or GMRS, because HF has LOS propagation, like GMRS, but also has the advantage of Ground Wave and Sky Wave propagation as well. However, very few people I have met in my entire life, have a properly installed CB. Even fewer have SSB to take advantage of the extra power and sideband performance characteristics. I only know one person (personally) that has an FM CB. Bad performance of poorly installed factory stock AM radios that only put out 1 or 2 watts and 75%-80% modulation on a good day, and the lack of operators with compatible gear for SSB led me to recommend the much more powerful and installation forgiving GMRS. I have an AM / FM CB. Ive done a test similar to what you mentioned, comparing AM CB to FM VHF and UHF. While I didn't compare CB AM to CB FM, my results showed a dramatic range improvement with a 50w GMRS radio compared to my well performing AM CB. Living here in VA, I should try to find some time to duplicate your test, to see how terrain and woods impact performance. I'll have to see if I can get the one person I know with an FM CB to run some tests with me.

  9. What is it that you think people should be saying on the air? What is it that you say on the repeater? Maybe you could be the one to start the ball rolling. GMRS is not ham radio, where people actively seek out people to strike up conversations on the radio just because the radio is there. GMRS is more designed to be a utility for two people or an entire family who wish to communicate, generally while doing something else, possibly recreational like hiking, biking, etc., or possibly as a business, like farming or ranching.

  10. The more I learn about the FCC's General Mobile Radio Service (GMRS), the more I am fascinated by RF in general. It touches everyone's lives every second of every day, yet few people pay much attention. How cool is it that after 42 years and 14 billion miles away, the 22-Watt radio on Voyager 1 is still sending data back to earth every day (how important is that antenna?). So why aren't more people interested in GMRS or RF in general? There's no test to get a license like amateur (ham) radio. It's $70 for a 10-year license, and is really easy to get started. So here are some theories. People don't know: GMRS exists Why GMRS exists Why they'd want to use GMRS How to envision themselves participating in GMRS What it takes to get started with GMRS What it takes to continue and improve with GMRS Technical information they should know about GMRS Etiquette when transmitting (TX) on GMRS What a GMRS "Net" is and why Most people within the GMRS community are helpful once you're in, but the community is very inviting in a go-figure-it-out-yourself way, and no one has assembled everything you need to know about GMRS all in one place. We GMRS people are putting the onus on outsiders to sift through thousands of painfully esoteric webpages with a winnowing fork, separating useful info from useless, poorly written, or incomplete info. When I first heard about GMRS on a 4x4 trip, I arrived home and Googled around and settled on a Midland MXT-275 because it seemed perfect for mounting on my truck dashboard. At the time, I had no idea that Midland doesn't manufacture a GMRS radio capable of operating on split-tone repeaters (Dear Midland, I know you're reading this: why do you squander so much potential?). Edit 6/28/2021: Midland heard our cry! They just updated the MXT-275 to include split-tone programming on repeater channels. So for example, now this radio is able to reach a repeater that receives (RX) incoming transmissions on 467.550 with a PL tone of 103.5 and repeats the transmission (TX) at 462.550 with a PL tone of 88.5. I didn't even know what "split tone" was or even what "tone" meant, or carrier or squelch or hundreds of other little things you all take for granted. Since then, I realized that if the big, bad manufacturers like Midland, Kenwood, Motorola, and iCom can't even invite the public to learn more and provide useful content for each stage of the customer journey—Awareness, Consideration, Purchase, and Loyalty—the 2-way radio industry has much deeper problems and aren't there to help guys like me. As we get involved deeper into GMRS, there's little-to-no hand-holding going on at each level of knowledge. I ending up relying on the Ham community here and there and a guy who is basically a saint at a little radio shop in Phoenix, Arizona (hope Tim over at Procomm and the others at the nonprofit AZGMRS.org don't mind me giving them a shout-out). Edit 4/14/2020: By the way, AZGMRS made this awesome list of FCC-approved GMRS radios that they recommend. If you live anywhere near Arizona and are reading this, now would be a great time to become a member. Their repeater network covers some 100 miles around Phoenix with more and more repeaters joining the network (check out their sweet coverage map). But it's still frustrating. I wish a GMRS expert—presumably a manufacturer—would just come out and say exactly what a total newbie needs at each stage of their involvement or level of need. Two-way radio manufacturers should stop wasting time trying to sell, and start marketing and branding, which means educating the public about the 5 W's (Who, What, Where, When, Why [+how, +how much]) without trying to sell to them. Most new users don't know what they need because they don't know what's possible. For example, I wish I knew that manufacturers don't typically include the best antenna on their radios right out of the box. It took me over a year to realize that the best bang for the buck for a portable base antenna to include in my go bag is N9TAX's Slimjim and that Smiley Antenna makes the best bang for the buck antennas for hand-held radios (which by the way, everyone just assumes newbies are supposed to know that hand-held walkie-talkie radios are called "HT" for "Handy-talkie" and what a "QSO" is). How would a newbie know that the cheap Nagoya 771 "upgrade" antenna for Baofengs that everyone talks about actually isn't the best bang for the buck for the GMRS frequency band of 462–467? How would a newbie know that antennas work best when tuned exactly to what they call a "center" frequency that accommodates 5 Megahertz in each direction (+5 and -5 Megahertz) at the expense of hearing other frequencies? I learned the hard way that in order to properly install an NMO antenna mount on the roof of my truck, I would need a drill bit specifically made for drilling NMO antenna mount holes, and that yes, it is worth the money to do it right the first time. I'm still in the middle of learning how a "quarter-wave" or "5/8 wave" antenna works, the difference between dB gain vs. dBi gain, mic gain, antenna gain, because again, everyone seems to just assume I already know what all this means. I still don't understand what antenna "tuning" means and why you have to "cut" an antenna to "tune" it. Can I make my own antenna right now in a pinch with a copper wire in my garage? Ok, show me! How do I measure it or test it? What is SWR? Can I measure it myself? What do I need in order to measure it? Is one SWR meter better than another for my level as a newbie? Is there something I should learn to make it worth buying the better meter that opens up a whole new world of capability? Is it worth learning all that? This graphic did a great job beginning to explain what dBd gain means for those of us who know next to nothing about it, but now I need to go find out on my own and sift through a thousand webpages to find out if dBd is something new I need to know. Speaking of dB, I know that "dB" is a decibel, but is it the same as my stereo volume? Why do I see manufacturers saying that the microphone and cable have a dB rating? What is going on here? This is madness! We can Google things all day, but which info is true and correct and the most helpful? I think that the entire industry is sitting on a Gold Mine of consumers sitting at home for weeks on end who would love to buy GMRS equipment and communicate via GMRS to friends, family, neighbors, and other GMRS users. Whoever provides the most useful, relevant, and engaging content that stops making assumptions about what people know or don't know will win. STOP ASSUMING. START EDUCATING.
