Ok, so what is between 450.0 MHz (end of 70cm) and 462.5625 (beginning of GMRS) or between (top of GMRS) 467.7125 and 902.0 (bottom of 33cm) Kinda new to alot of this and I have nothing to scan these frequencies with. But they are NOT in the Ham spectrum, so what are they used for? And could GMRS expand into them?
Ok so the existing GMRS would not be able to use them, but the FCC recently authorized FM to the CB world..Thanks to Cobra electronics. how many old CBs have FM? We started with 23 channels AM & SSB, then 40 AM & SSB now with FM

What happens when a soldier speaks to a truck driver? Both have special acronyms and codes, Then a LEO gets involved, again different codes. So, a lawyer who speaks in circles and is incapable of answering a simple question gets involved with alot of leagaleese and double speak so it's nearly impossible to get a clear message. The FCC does not understand or really care so the OK it and there we have it..Everything should be in clear and concise English. And Alice Cooper says "mixerthingwhaynowbatcrapwhatdaywasitbefore." and we are all confused.

I have an older ICOM IC-731 that I still like, goes from 0.100.0 to 29.999.9 and everything in between. My BAUFENG will get me into the 2M and up, just no FM or SSB. About the only thing I can't get to is the 60M 50MHz band...Maybe not the newest whizbang equipment, but it works

I dont usually travel in a group, but when if/when I do its with a CB. It still has way more users and gets better range. I have a Nagoya Model NMO 200C antenna with NAGOYA GPK ground plane sitting at 35 ft and usually don't pick up anything. I push 47W and can't talk to repeaters 20 miles away. So far GMRS has been a big waste of money. I left it on scan from near Austin TX to Shreveport LA and didn't get a peep. Travel channel? Pick any of them nobody uses them anyway.

I picked up an ICOM IC731 but can't find any manuals or information on it. 19.76.5-29.976.5 I don't have the right antenna set up yet. Is the ATU 100 EXT a good antenna tuner 18-50MHz? Just kinda waiting to buy a tower/antenna and all the bells & whistles.

I'm hearing a repeater Loud and Clear, it says "welcome to the military repeater", I should be able to reach it as I'm less than 5 miles from FT Hood. But so far nothing..It transmits the same message about every 30 minutes or so...Is there any way to find out if it uses input or output tones? Or any information? Its on 462.550 Ch15
Also while scanning this morning I spoke with a ham operator about 12 miles away, who was just playing on the GMRS band...

If I only wanted to talk to my wife I would have got a MURS 900MHZ radio. or simply walk into the other room. I got into GMRS to talk to other people. Not chatter away for hours but check on road conditions or events. There is only one repeater that I should be able to use, but so far nothing..don't know if I'm doing something wrong or just can't reach the distance. I've put it on scan and pick up NOTHING ever. Very disappointed by the whole deal. At least with the little CB in my truck I can hear the gravel haulers and a few other trucks that come thru daily. But no locals.. I've scanned the 10M band, the 12M band, 2M and 6M bands and only thing I pick up is a religious station in Nashville. So, I see no reason no get a ham license. Granted I don't have the right antenna for Ham bands.
I've put quite a bit of $$ into the GMRS just to hear static. Radioddity DB20G on a Nagoya NMO200c high gain antenna with Nagoya GPK-01 ground plane, sitting 25ft high. A Wouxun KG 805G and Baofeng UV 9G handhelds, and the Midland MXT500 in my truck. And all I get is static.

You have confused frequency band (CB) with channel bandwidth (GMRS). GMRS operates on 462/467MHz (approximately 60cm). CB is ~17 times longer in wavelength, and with only 4W output, probably won't be seen by a GMRS antenna. Conversely, even with a 50W transmitter, the CB antenna is unlikely to capture too much of a signal. (The mag-mounts on my rust bucket are only about 18" apart)
thank you I've edited the question. I was reading it wrong.

Some fantastic info on coax, very informative. But why when you buy a GMRS radio that comes with and antenna is the coax so tiny?
OK, On to my question, how far apart should the base antennas be for CB 27Mhz 11 M and Gmrs 462--467 MHz both are vertical with ground plane. Both will be around 60 ft. I will probably never transmit on both at the same time but I don't want bleed over. I know the coax used will have alot to do with that too.

There is one in Troy TX I'll have to find his info

Open up the Ham 2 meter and 70 cm bands to transmit on the USA version (also available in the provided software under Model):
1) Turn off the power.
2) While holding down the V/M button, turn on the power. Use the Up and Down arrow keys to change from the GMRS setting on the display to 136-174 MHz; 400-470 MHz and now power down.
3) When you power back up licensed operators can now transmit on the GMRS channels and the 2 meter and 70 cm Ham bands.
OK please explain how to go back to GMRS. Was fun for a minute. Never mind I got it:)

One downside to "opening" this radio is it takes forever to scan It goes past the 450.0 MhZ on 70cm 420MHz and below and over the 144.-148.0 mhz on 2 M 144 MHz. of course it does NOT have side band so your not going to hear alot of conversations. You will get the noise from what I assume is data, loud static.

The Radioddity DB25-G is CHIRP compatible according to the website, kinda wish I'ld gotten that rather than the DB20_G
Multi Band? JMHO if your licensed for GMRS and Ham why not? Unless your running too much power, how does the FCC know what radio your transmitting on? A "modified" GMRS or an unmodified ham radio? As long as your legally licensed to operate those frequencies.
Power? go to CB ch6 27.025 any evening. Sitting in central Texas with 1 ft of coax on a 100W dummy load I can hear Orlando FL, Lansing MI, a Few way up in the NE Main, CT NY NJ Them boys are putting out some power. ch 17 and 28 are just about as bad. I know some of you would rather take a butt whopping than mess around on 11M 27mhz but its alive and well LOL

I'll be doing 100% coax I have a Surecom SW 102and Surecom SW 33 mark II. to check SWR and power. I was certainly disappointed to learn all my CB test equipment SWR/Power wouldn't work on GMRS. I do have dedicated GMRS antennas but they look just like the ones that come with the little CBs that are on the market. Fit in the palm of your hand, some dead key around 6 Watts and swing 10-15Watts I run a President Bill in my Ford Ranger but have it on a 5 Ft firestick, SWR is 1.5/1 to 2.1/1 from 25.615 to 29.205. If I'm on a longer trip I'll put in a RM AM/SSB KL23P 100W linear. On a good day it will talk across the grass median.
Ran a Midland MXT500 for awhile, with the included antenna, I was not at all impressed. Nobody out there. Of course alot of places I go there is NO cell service, NO FM radio, and AM is the boarder blaster Mexican stations.
So, I was thinking of running the Midland as a base station, and as long as I have the pole down put up a good CB Base as well. That's another story on a different forum..
Guess I'll go looking for an antenna analyzer. And see if I can figure out how to use it.
Rules can be broken, Laws cannot (should not). So don't lecture me on power and frequencies, I know the rules.

Over the years I have acquired a few antennas, Is there any way to identify which would do UHF Gmrs, which are 10/11 meter, which are 2M ? I was goofing around on a Ham equipment site last night after a few adult beverages. I saw a antenna matcher, supposedly whatever freq you transmit on it matches it for optimum SWR and impedance. It wasn't cheap, but with all the multi band, or any band radios, with on heck of a frequency range... I guess you could do it all with one antenna?
If I used the wrong terminology or misspelled anything, I'm not a Ham operator. I spent years OTR using CB everything from "converted 10M" to Pres. Bill, alot of Cobra and Unidens. Yes I've played in the "prepper bands" or "free bands" Retired now with too much free time on my hands. LOL

I have a Cobra Micro talk (bubble pack) FRS with 22 channels, each channel has 38 sub channels. My Wouxun KG 80G has 30 channels but I cant find the sub channels. I'm not sure if this is what the OP was referencing, If the Cobra is on CH 4.25 the Wouxun won't pick it up, If the Cobra is on 4.00 the Wouxun will pick it up loud and clear out 1/4 mile away.

That's a nice pole, but with the guy wires has a pretty big footprint. Do you encounter any issues with no ground plane, except the ground of course. While the hunting tower has the expanded metal..Here, where I am, the ground has very little reflective properties. Mostly limestone and sand. I see people using aluminum pipe from the top of a wire fence, or a few sticks of PVC, and all sorts of redneck engineering. For your heavy rotor and a set of moon rakers, you could remove the seat and use the pedestal.
I'm just kicking around ideas right now.

Saw this earlier today and thought HMM a 20 foot tower! I'm thinking even multiple antennas for different radios or frequencies

Yeah I guess I need a label maker, I have CRS real bad these days.

The "chip" shortage for new cars is a good example. There are no American made CBs either, I have an old Lafayette 23 channel that was made in America...maybe. The crystals were probably not. Like it or not, its a global economy
-
If the cig lighter plug is a problem, why not change the connection to a two wire plug, think 110V home plug with one wide one thin so you cant plug it in backwards. Or the push to connect like the front of a power supply.
-
Thanks for the info. I'll see if I can find it. WRPC505, i'm just off FM 2657 probably not too far away

Most oil and gas workers are outside contractors, and don't have the capital or want the exclusive systems as they work for many different companies. I've worked for as many as 10 different companies in a week. Out there where there is NO cell service, No road signs (or no roads) and No directions. Many times I've put Long/Lat in my GPS and hoped for the best.
A "BIG" repeater? maybe one that works for more than 2 miles? or one that works 10-15 miles compared to one that works for 70 miles.
I was kinda thinking the 102 for base operations, not so much mobile. But thanks y'all for the input. I'm coming from the CB side of this, so alot of it is still fuzzy math and voodoo science.

I use a Nagoya NMO-200c with GPK-01ground plain. on a 45 ft. pole it does OK
