Hey everyone, need your thoughts on the CB subject. I have been out of it for awhile cbs. Not sure if people still use them to chatter.
I would like to get one, but not sure if really needed, living in the modern world of cell phone, on star etc.
your thoughts.Thanks

If you are going to go wheelin with a group it is nice for inter Hummer communication.

I just swooped up a cobra handheld off of ebay for 25 buck, and paired it up with an external antenna. It's a pretty solid set up for a little over $50.

I will also say that it does come in handy for on the minute weather...

Besides CB radio and the low-power FRS handhelds
that are so common today, there are also
very cool and flexible radios in Amateur Radio
i.e. Ham Radio. I have an Amateur Radio license
(very easy and free to get) and the H3 looks
great with nice dual-band antennas on top.
Lots of mounting room up there on the roof.
See for yourself:



There are lots of cool-looking 50-watt mobile transceivers to choose from,
and mountaintop repeaters and GPS beaconing and voice Internet linking and such to play with.

Good for those with at least some interest
in RF engineering and transmitter details, anyway.

Thanks for Sharing, Im going to do some homework and go for it Boys and there toys!!!!

Hey gc2488 .. are you running 2-meter and 440? .. why didn't you just go with one dual band antenna? I'm getting ready to put my yeasu 857 in my H3 if I can make it fit somewhere .. any problems with your computer or onstar when "keying" up? my ft-857 will put out 100 watts so I'm a little worried about interference .. my 2001 GMC would shut off every time I keyed the mike when transmitting in the HF bands with over 50 watts of power "73's"

Hey h3humvee! Yes, 2-meter and 440, with two radios --
One for voice (Yaesu FT-8500 with microphone with many buttons)
and the other antenna for data (Kenwood D7 with built-in
computer interface, like for APRS position beaconing and messaging).

No, I haven't noticed any RF interference problems with the H3
although one 80-watt 2-meter amplifier I used in my Volkswagen
did mess up the car's ECU causing the check engine light to
come on while transmitting. Funny on the interference with the GMC too.


I would like to do other fun radio and mobile Internet related things
like mounting a laptop on a nice adjustable arm holder,
and installing a Wi-Fi access point that would get to the Internet
through a cell phone. Cell phones fail in remote mountain areas,
of course, and that's where the high-power Amateur Radio equipment
is really fun to use.

It's also pretty cool to see mobile satellite internet systems becoming
available (but still very expensive, like over $5000 for installation).
I heard of one guy installing one of these motorized satellite dishes
on an H2. Wonder if anyone has put one on an H3 yet...

I am running 100watts (HF) in my H3. Using a IC706 mk2 and have no problems at all.
Remote mounting was cake, using a trunk lip mount on the bumper for my quad band antenna.

Nice to see another radio op here, and greetings to everyone else! Name is Tim

We use FRS at Paragon, jkH1. CB's in Moab.

Out here Cb's are a mandatory requirement for trail use. FRS is for intercommunications between friends but with the maountains and sometimes the range needed they(FRS) dont work so well. i run the Uniden 510XL in my Jeep and a Midland in the H3.

Got the 40channel cb tonight ready to fire it up tomorrow, let you know what happens. Thanks again for everyones advise. Very cool.

be sure to post pics of the install

Hi Tim and everyone, thanks for the note about seeing
no interference with the H3 when using 100 watts of power
on HF. Sounds good, maybe shielding is done well
like many things in the H3. My license is KK7DV,
in northern Utah most of the time and sometimes in
Bear Lake county Idaho.

Any ideas for routing coax from roof antennas is of interest.
I just used temporary magnetic mounts stuck to the roof
and closing the door on the coax cable.
Of course many permanent installations involve drilling holes
through the roof and routing cable after removing "headliner" cloth.
For temporary, changing antenna requirements I wonder if
it would work well to have a special larger hole with waterproof
fixture, and a cable routing tray. Fun.

Can't you run the cable through a marker light?

stupid question, frs hand radios, do they communicate with CBs or is that a different frequency... Thanks for the help.

They have their own frequencies

Talking about broadcasting... Do you really feel that it's a necessity to let everyone know your sexual orientation? Maybe you just crave attention.

You can run it down the A-pillar molding and in through the grommet in the DS door.

the pillar idea sounds good to me. I absolutely hate to drill into a new vehicle- inside or out!
Any installs I have done in the past years have nearly all been "no-drill".
The radio itself is under the drivers seat. I sealed off the heat duct with aluminum duct tape (real metal duct tape, not the fix-all stuff) and to keep the radio from sliding I popped a piece of velcro on the bottom. Used the harder loop side of the velcro.

For a mic hangar I used one of the command adhesive hooks from 3m. Radio head mount was done with a special swivel bracket I picked up at HRO.

This H3 is actually the first vehicle I have been able to NOT install a line filter on. I have had no alternator whine or ground loops at all....

I can post a pic if you want to peek sometime.
