Two week excursion

Going on a two week excursion, off road mostly the whole time with camping on the way.

I've always been curious as to when a cb radio is useful and when a ham radio is more conducive. So what is the right solution for what situations? We will be driving with two other jeeps and we all lack any type of radio system to communicate and are looking for the best solution. For safety, to be able to communicate if we get separated etc

If all you are doing is talking to each other the CB will work fine and requires no license. The range is not great, but the 2 meter / 70 cm Ham units are not significantly better since they are line of sight. My wife and I are both licensed so we tend to use the Ham since the FM signal on 2 meter / 70 cm is nice and clear. Oh, and the Ham stuff costs a lot more. We used to just use FRS radios. They will get you to the next Jeep and it is nice to be outside directing someone and be able to talk to them. Sometimes the hand signals just don’t say it all.

We will be off road for two weeks in September in the boonies of Utah. Right now I have a CB and a VHF Ham rig. Trying to decide if I should put in an HF Ham rig to get to the outside world. VHF repeaters are few and far between in south eastern Utah. I have a General license, but my wife does not. I guess I will have to do all the talking on HF.

OP, I think the simplest solution for your trip would be to use CB. They are pretty much plug and play and you don't have to worry about everybody getting a license.

Ham radio can be fun, but the equipment is more expensive and you have to learn how to operate the radio's. They generally are a bit more involved.

New - Don't forget techs have 10M voice privledges, and third party communication is allowed.

Thank you for the replies guys!

So cb is good for vehicle to vehicle, which should be fine for this trip.

You guys have peaked my interest in ham however. If I wanted a ham radio, what kind would I be looking for to reach out farther than line of sight?

Beyond line of sight requires a VHF to bounce off a repeater. And you need to be line of sight to a repeater (they are usually on high points, so that makes it easier). In developed area you will find lots of repeaters. There are repeaters from Corona to Banning and Crestline to Temecula, so the Inland Empire is covered pretty well. But for instance there are no repeaters in Death Valley National Park, so you better be on Telescope Peak or Dante’s View if you want to have a chance of hitting a repeater. That is not to say that you might not reach another ham in the general area. A lot of offroaders seem to run 2 meter VHF radios.

HF can bounce off the ionosphere (VHF generally goes right through it into space) and therefore can get you a lot further out. Like to other countries further out. Operating in the HF bands that will be the most useful in getting long distance require a General license. Technician is the first level of license now and General is the next level. The tests are not too bad if you are a techie, but if you are non technical they can be hard. My wife the accountant passed her test the first time after she took a "ham cram" class, but just barely. She just memorized enough to pass. She still can’t tell a resister from a capacitor. But then you really don’t need to know that to operate a radio these days. Check the band plan for what frequencies you can use, dial up a frequency, push to talk, use your call sign every 10 minutes and be polite. Most VHF radios won’t let you talk where you are not allowed to be. For the General test I had to remember a lot of college physics. It was actually fun to relearn that stuff.

It sounds like we might be covering some of the same ground on our trips. I am just coming out of the Bay Area and will end up in southeastern Utah and southwestern Colorado. Have fun and pack a cell phone.

OP take a good look around here. Home They have training materials, information on amateur radio clubs near you, and testing sessions.

This site has practice exams you can try to see if you are ready for the real thing. Callsign Database by QRZ.COM

Feel free to PM me if you want to discuss in depth.

It's a lot of fun and there is much more you can do besides talking Jeep to Jeep.

So is CB line of sight?

Because let's say I've been separated from the other jeep and there is no cell service.. Can I use CB radio for this? How far out does CB work?

Line of sight refers to visual horizon. Two objects that are not hidden from each other by the curve of the earth. (or a mountain)

General figure for CB, 5 miles in relativity flat terrain. If you get down in a valley you are going to be limited.
