Dual Band VHF-UHF Radio Recommendation

I'm hoping someone can help me with selecting a mobile 2 way radio for my jeep. I already have a good CB as well as a Garmin inReach. What I need to do is to be able to talk to my Rugged Radio VHF buddies and my UHF GMRS buddies in a single mounted dual band radio. I already have a handheld.

Here are my requirements:
• Under $400
• True dual band operation
• Screen that displays the A and B frequencies
• Can receive and transmit on VHF-FM Hi band (150-174 MHz)
• Can receive and transmit on UHF GMRS frequencies (462-467) MHz)
• Decent speaker audio

Nice to have but not a requirement:
• Capable of operating in the UHF and/or VHF amateur bands
• Invertable faceplate capability
• Adjustable transmit power levels

I did a quick key forum search on WF before posting this but didn’t find anything with specific requirements.

Yes, I will get the necessary licenses to operate legally. Thank you.

The radio you describe would not meet FCC regulations because ham operators cannot legally use radios capable of transmitting on both the ham and non-ham frequencies such as 70cm ham (420-450 MHz) plus GMRS (462-467 MHz) or 2 meter ham (144-148 MHz) plus the UHF frequencies utilized by "race radios" (150-174 MHz).

I'm sure someone can help you, which will likely involve modification of a standard 2m/70cm dual band amateur radio, but it won't be a ham who believes in compliance with the rules.


My usual advice is to stick to one of the three major brands: Yaesu, Kenwood or Icom

It can be done, it's not legal though.

Google Mars-Cap and look at the Kenwood TMV-71a and Gigaparts. You will also need to factor in about $100 for a decent dual band antenna.

Again, this is information only, I don't condone violating the rules established for the airwaves.

Dedicated ham radios from the major manufacturers are locked on the ham frequencies. Some can be opened up by taking them apart and removing resistors/diodes etc. It's that not easy to do if you aren't familiar with electronic soldering.

You can pick up a cheap dual band Chinese radio.. They aren't high quality, but they'll do the job. They're sold as amateur or ham radios because they're only legal to use by licensed hams on ham frequencies, but they are wide open on the VHF and UHF bands.

Here's one: https://www.amazon.com/TYT-Waterproo...ds=TYT+TH-8600 It's just as good as any of the other Chinese fare out there.

As mentioned in the other posts, this radio isn't legal to use on FRS/GMRS/MURS. I'm not condoning it either, but if you use one and keep on the designated FRS/GMRS/MURS frequencies you should get away with it. (You can look the frequencies up on Google). Tuning the radio to ham or commercial frequencies can get you noticed.

Oh, and you need a license for GMRS. There's no test, you just pay a fee and it's good for 10 years.

So the Powerwerx BD-750 seems to be the radio that can meet all of my requirements and the nice to have features I listed in my original post. It's also FCC Part 90 certified. Guess I'll pay for my GMRS license/permit and go study for the ham test.

Study and you can get your Tech license easily. I studied the question pool and used the on-line tests. Aced the Tech exam with about 4hrs of study time. Missed the General test by 3 question even though I had not studied for that at all. Studied and passed the General test about two weeks later. Hope this encourages you to GO FOR IT!

I'll concur on getting a ham license isn't too bad. There's a number of sites with flashcard style study section and practice tests for all 3 classes. I spent about 3-4 weeks of study for the Tech and General tests and managed to pass those and sit for the Extra test and scored 50% on it though I never looked at the data. General will grant access to additional bands which can reach further which could be helpful to have.

I encourage all those interested to get their license, but rather than learn the questions and answers, learn the material itself. It's not difficult and you will be surprised how useful it can be.

My goal was to learn and be able to pass the test. In the process I learned a lot about propagation, antenna types/function, and the rule around use of public airwaves that I did not know. Since getting my general ticket I discovered I am interested digital radio. I bought a sound card kit and built it to use with winlink. Still have a lot to learn. My point is that having a goal to pass the test was a great for me. With what I learned studying for the test it has spark a greater interest go learn more.

Very good, that's a big part of getting a ticket, learning about radio. As you found a lot more involved than CB or FRS.

Re: Winlink, it can be done with a soundcard using Winmor its the slowest flavor and a rather specialized mode.

If you want to do digital on HF get a copy of FLDIGI, it's free.

https://sourceforge.net/projects/fldigi/

FLDIGI supports a lot of the digital modes in use like PSK and Olivia. It will even do CW.
Digital can be fun. Much more efficient than voice and lets a very modest setup work the world.

You can PM me with questions or we can continue here.

Icom, Kenwood, Yeasu, all have dual band mobiles in the $300 range with removable faceplates.

None of these tx outside of ham bands without mods that void warranty.

More importantly, Kenwood, Yaesu and Icom are all well-respected companies that do not market ham radios in the U.S. capable of transmitting outside authorized bands because such such radios would violate FCC regulations. These companies have far too much to lose by ignoring the law.

If you want a non-compliant radio that can transmit on ham bands and FRS/GMRS frequencies then buy a cheap Chinese Baofeng. Apparently Baofeng doesn't take the FCC seriously, nor does Amazon which is Baofeng's primary conduit to the U.S. market.

Every time a noob asks about a radio he gets educated about rules and regulations but he barely gets his answers. What he does with the radio is his business, how he does it is also his responsibility.
Let's clarify :
"Radios do not transmit out of band. People transmit out of band."

The responses to OP's original query were direct and to the point:

(1) There is no single radio that can legally transmit in the U.S. on all of the frequencies specified by OP;

(2) None of the major manufacturers of ham radios, VHF business band radios or FRS/GMRS radios market such a radio in the U.S.; and

(3) if one wants such a radio one must resort to cheap Chinese imports that do not comply with FCC regulations such as Baofeng, TYT, the re-badged Chinese radio sold by Powerwerx, and Zastone.

Simply because one doesn't like the answers doesn't make them any less complete or any less accurate.

There are two kinds of radio manufactured in China:
1. Overpriced (Yaesu, icom, Kenwood, etc)
2. Reasonably priced (the rest)
They all do the basically the same thing - facilitate communications. Some have more features than the others. Some are poor copies of properly designed radios and some are improved copies or new products.
The Zastone D9000 I refferenced is a succesfuly improved copy of the now defunct icom 2820 that people raved about in its time. It's not baofeng cheap and performs as good or better than the original.
Before we start arguing about copying and improving technology by the Asian manufacturers, let's remember the Japanese got were they are today by copying and improving American technology starting in the 70s. They were bashed at the time but in time they gave us Yaesu, icom, Kenwood and the likes that we use as refferences today.
In terms of legality and user responsibility, all the major auto manufacturers make cars that can drive above the posted speed limits. People drive them regularly above the posted speed limits. They are still legally sold and driven in US. The drivers drive them illegaly at high speeds, get caught, and fined.
The FCC rules about the radio transmissions in discussion are questionable and limit the progress of technology as well as freedom of communication. Ie.Why can one tx in gmrs freqs with crappy (but grossly overpriced) walmart bubble pack radios but cannot do it with high quality radios like Yaesu, icom, Kenwood?

No need to buy a beofeng. If I was looking for an amateur radio that would be usable where I want I would look up the radio of interest at mods.dk to see if a mod exists that will open up the frequencies of interest.

I agree that the FCC's rules about hams not being able to transmit on CB and FRS frequencies are dumb. One would think that a ham should be able to transmit on any frequency that a non-licensed person can, using his equipment in an identical fashion (limiting power, for example).

But them's the rules. *shrug*
