That’s the correct screen. Now just change the mode. I think it’s the up and down arrows but I don’t remember for sure. 

@WRQC527 Is that the Mystery Machine? 

@WRQC527 Is that the Mystery Machine? 

I got to do a range test today and I am very impressed. In an area I typically get about 5 miles of simplex range with a 50w VHF or UHF radio (Ham and GMRS) I was able to have a conversation at 14 miles apart, while moving. 
 
One of my friends who also has a good AM/FM CB and a good antenna setup were able to run a test while driving in Norther Virginia. I have to say, 14 miles for both AM and FM is fantastic around hear.
 
The furthest I have ever talked on a CB on the local level was 26 miles, using a 104" (1/4 wave) steel whip antenna and 12.5w peak. 
 
This 14 mile contact was using 3.5w and a 86" Diamond HF10CL antenna, which isn't as good of a performer as a 1/4 wave would be... but it's pretty darn good. Much better than if I tried a 3 foot or 4 foot Firestik, I'm sure.
 
This radio seems like a win for a compact FM CB. 

Are you using a repeater channel or are you on a simplex channel? Repeater channels usually have a R after the number,

Ohh yeah, I forgot to mention that.  I agree with WRQG411 on the Midland PL259 mount / cable.  I was able hide the cable in the gap between the frame and the fender cover fabric.  Just loosen the bolts holding the top on and shove the cable behind them.  From there you can run the same line down until you reach the rear floor mat.  

One thing I like about the Midland mount/cables is that the PL259 connector unscrews from the cable and is much smaller, allowing a smaller hole for bringing the cable into the cab of the vehicle.  The 400 is popular as I understand that there is CPS available to program it, while the 275 and 575 are programmed from the hand mic.

Just so you know, the MXTA26 antenna does not include a mount. You’ll still need to get some kind of NMO mount to attach to your jeep and accept the antenna. Many mounts include the coax cable as well. 

First, you must select a repeater channel.  Repeater channels and simplex channels will both receive the repeater transmissions, but only repeater channels transmit on the correct frequencies for the repeater.
Second, you must transmit on the repeater channel using either the CTCSS or DCS tone that the repeater requires as its “Input” tone.  Transmissions received by the repeater that don’t include the correct tone are ignored.
For instructions on how to set your CTCSS or DCS tones, your instruction manual is your best reference.  I don’t have an MXT400. Maybe someone who has one can answer more specific questions.

I think you two missed the point of what I was saying. But that's ok. People miss points all the time. The idea is that FRS radios are supposed to be low power with no license required, but with removable antennas, that purpose would effectively be defeated. Carry on. 

Part of the issue I think is because FRS radios are low power and short range and are required to have a fixed antenna, likely to keep people from using bigger antennas and amplifiers to increase what is supposed to be low power and short range. Lots of GMRS and amateur radios have removable antennas specifically to enable users to increase range and power using upgraded antennas and amplifiers. Imagine a world where someone could jack up the power and coverage of FRS that way. That's one reason for a rule not allowing multi-service radios.

I'm going out on a limb here that the FCC puts a very low priority on anything to do with GMRS, MURS, FRS, CB and amateur radio. I keep thinking they're saying "Look. We finally dropped your license fee to under a penny a day. Heck, we don't even charge you for some of the services. Now stop bothering us and go outside and play with your radios." 

Well, after 3 years without a CB radio, I bought a new unit. It's a Cobra 75 All Road.
 
I haven't been following CB, but i do know the FCC rule changes about a year ago now allow FM use. I have been curious about it, especially knowing how well FM works on 29 MHz. I had a customer tell me they were interested in this radio, asked if I had an opinion about it and asked if I would install it for them. So, I bought one to check it out.
 
I have to say, it's a little weird running a "stock" CB... but so far, I like it. It's just AM/FM with weather channels, but the transceiver is remote and the controls are in the mic (a familiar setup). BUT, the mic and all the controls are done wirelessly. The mic plugs into any USB port you have, or comes with a power outlet adapter. The mic works over Bluetooth so well, that I had the transceiver in my Jeep, but tested the mic range in my son's Jeep. It works about 30 feet away, which was awesome. 
 
I haven't chatted with anyone yet, but I was listening to AM Skip from all over the country. The receiver sensitivity seems real good so far.  I am going to ask a friend of mine with an FM CB to help me do some range testing. I'll follow up soon and share the results. 
 

 

Actually, @OffRoaderX is a Time Lord.  He does what he wants when he wants.

It was in “humorous” tense.

The principal is based on generating a high frequency AC current in a copper “coil”, for lack of a better term, in close proximity to the surface that’s to be heated. The high frequency magnetic field induces a current flow in the surface of the metal. The depth the current penetrates depends on the frequency. The higher the frequency the closer the current remains to the surface, skin effect. Since the metal has resistance heat is generated from P=R*I^2 effect.

In about 2 weeks ago.

Transmitting with one radio and listeniing with another radio right next to the transmitting radio is not a reliable way to determine that you're not transmitting.  The listening radio may desense and become deaf because of the proximity of the transmitting radio.

Poorly maintained transmitters can transmit on secondary frequencies or spill over widely around their primary frequency.
Poor quality receivers can receive nearby frequencies.

Several UHF TV channels exist in the 470-490 MHz range. You may just be hearing one of them.

What type of antenna connector does it have? For that age, likely a BNC. Pretty much ANY 2m/70cm BNC antenna should be compatible.

Good luck in your quest.  I read the title and thought it was about the new Kenwood handheld which has a very similar name TH D75A:
