Connect a VHF to a UHF?

Is it possible to connect a VHF radio to a UHF Radio, if so how, I have a Motorola gp68 VHF. If not can you connect a Motorola gp68 (VHF) to a regular walkie talkie, how. Thanks

Hi jj, Danny answered your question yesterday in the other thread. VHF and UHF radios operate on different frequencies and cannot connect or talk with each other. For more in-depth discussion on the difference between UHF and VHF radios, listen to The Two Way Radio Show TWRS-02 - An Introduction to Business Radios and for a quick, clear explanation on the differences between UHF and VHF in less than two minutes, watch the video Radio 101 - The difference between UHF and VHF radios. Also, in the future please try not to double post. Thanks!

Ok, Thank you. can you recommend a UHF radio with a Motorola 2 pin radio (two way). Please keep it cheap as possible ($70 under)

Unfortunately I don’t know of any Motorola UHF radios that sell for under $70 and have a 2 pin. The CLS1110 is as close as we can get, and they’re $139. They’re also not fully programmable, so that may be an issue depending on what other radios you’re trying to match.

Would a GMRS radio work for your needs? There are none that have the two pin Motorola connector, but they are less expensive. look for the Baofeng UV5RE, around 44 bucks. YOu will also need to order the programing cord if you want to have full programming access although you can program most of it by hand. The radio is UHF and VHF with 128 channels. The bad news is, that it is not waterproof so it won’t like rain.

You can buy microphones and it has the cheapest batteries I’ve seen and they are good batteries.

Also, anyone using these radios needs an appropriate license to use these radios. In the USA, any legal use requires either a business license, or amateur radio license. FRS,GMRS, MURS are not able to be legally used with these radios.

Go to the yahoo groups Baofeng forum and there is a thread there on the VHF/UHF hookup. The guy found a webpage that has pictures and instructions on how to modify the radio.

The problem with Modifying the radio is - that in the first place, if it can operate on both the GMRS / FRS and the amateur radio portion of the bands - it CANNOT be part type acceptable.

This is Verboten in the Part 97. - due to the fact that the public FRS only allows 1/2 of 1 watt and the GMRS only allows 1 watt.

The GMRS still requires a $80 license - good for 5 years - I think.

The Amateur Radio requires you to pass a 35 question multiple guess test given by other amateurs - not a easy test unless you already work in two way communications , are a trained electronic’s technician, or studied the Technician License manual.

It took me 7 days to read the license manual and 4 hours of studying to pass the test - and I already knew a thing or two about radio, and I barely passed.

There is no rank in amateur radio, the person that got every question right on the test is no better then the person who missed 9 and passed by the skin of their teeth.

The problem is - most people do not understand that amateur radio is not designed to be used as personal communications… The Part 97 and the ARRL says that anything that can be done by telephone - should.
And that you have to be willing to give something back to amateur radio to justify your license… Belonging to an active club, joining RACES / ARES and participating 75% of the time, doing community service, becoming a Volunteer Examiner - is a good start.

Most people do not have the time or the money to invest into amateur radio until after they are retired, which is one reason why so many of them only has a Technician class license and why so many of the active hams are over the age of 65 years.


Motorola have XTN line. They little cheaper then CLS but bigger and heavier.
I would recommend XTN XU2100 or XU2600

lol its unfortunate that i dont know much about UHF radios of motorola. and i am looking for those things desperately, anyone could help here???

A VHF radio operates in the range of 130 - 170 Megacycles - as a comparison - commercial FM radio operates somewhere between 88 and 108 Megacycles.

A wavelength - usually described in
Kilocycles - ( KC or KHz) 10^3 hertz
Megacycles (Mc or MHz ) - 1 to 1000 10^6
Gigahertz ( GHZ)- frequencies above 1000 MHZ or 1 billion hertz…

UHF takes place somewhere between 400 and 500 MHz in most radio systems

Microwaves - 800 - 900 Mhz…

If you have a VHF radio - you need a VHF radio to communicate with it, or a multi band radio that does both - license necessary - of course.

The same is true of a UHF radio - you either need another UHF radio or a radio that does multi bands simultaneously.

Find yourself a 2 way radio dealer or contact the owners of this web site.
They should be able to sell you what you need and get it licensed properly so you are not operating illegally.

All radio services (other then MURS and FRS - operating with less then one half of one watt) requires a license of some sorts.
