HAM Radio -- Off Roaders Dream


Several members of my club, the Motherlode Rockcrawlers, just passed our HAM license test (yesterday). That's Stacie and me in the middle. Yea, I know, I have on the wrong hat. :)
HAM is THE way to go in radio communications if you want to be prepared for an emergency, or just ensure you have good commo over long distance where your CB just won't cut it.
Now don't get me wrong, I'll still have a CB because I believe they are better suited for convoys and bs sessions. I'll run both in my rigs. CB's have no rules, so yea, that is a drawback when an idiot gets on line. But for the most part, the CB is a good tool for 4x4 rides and club events. However, if you want to up it a notch, take the time to study for the test, ensure you can have emergency commuications (enough to bring in a medivac helicopter), then HAM is the way to go. Add it to your inventory.
HAM radios can hit repeaters that allow you to literally talk all over the world pretty much.
You can get a dual-band handheld guy for a couple hundred bucks and do most everything you need to do. There are plenty of websites to help you choose equipment. And a good place to start studying for the test is http://www.qrz.com/. We spent about a week studying, a couple hours a day.
Del -- the new HAM (my call sign will be issued in a few days).

CB Radio and/or HAM?

Every four-wheeler should have a CB radio, especially for organized runs and events. A HAM radio is even better for long-range commo and emergencies.

But I get asked often about CB, so here’s the deal. Get a good one and an even BETTER antenna. Cobra is tops for circuitry and long-lasting use. Radio Shack makes a pretty good cheaper one. But if you want the best , and the one with the most gadgets, get a Cobra. $150 – $200 range. A Radio Shack (RS) simple one that will last a while and do pretty good is about $80. And the RS version is pretty gadget free (if you don’t need buttons like RF gain and built-in SWR, and mic volume.

I’ve had good luck with both. But whatever you do, get a good antenna. That is where most CB’s fall apart. Spend the money on a good one and mount it RIGHT (proper ground). Have it calibrated with a SWR meter. You will not be sorry. K40 is a great antenna, but even a good fire stick that is SWR calibrated will do the trick just fine.

If you find you can receive but not transmit; you have antenna problems. If people tell you your CB is garbled and squeaking, you have antenna problems. It’s nearly never the CB itself. Keep that in mind.

AVOID one-hander CB’s – the kind with everything in the microphone. If one thing goes bad; the whole thing is kaput. Also, in ALL my off-roading experience, I’ve never met anyone who could use a one-hander without inadvertently changing channels and losing touch with everyone in the middle of convoy ride. Get a real CB with a real microphone (that you can replace if needed). And yes, mics do go out and can easily be replaced (especially if you do Cobra or Radio Shack where they are easy to find.)

Here is some more info on my website if you’re interested.
