Ham Radio Gear – Part 2

Here are some example mobile transceiver options. Each of these is a dual band radio (2m and 70cm). Also each of these has a detachable, or detached, control head. I’ll add a note next to each with additional features.

Kenwood, Icom, and Yaesu are regularly referred to as “The Big Three.” They are the ham radio equivalent of Ford, GM, and Chrysler. There are other brands, but if we’re focusing on high quality, reliable equipment, these are the brands that are going to receive all of my attention.


  • IC-2730a – Dual Receiver / Cross Band Repeater
  • IC-880H – D-Star Digital Mode Ready
  • IC-5100A – Dual Receiver / Cross Band Repeater / APRS capable / D-Star Digital


  • TM-V71A – Dual Receiver / Cross Band Repeater
  • TM-D710GA – Dual Receiver / Cross Band Repeater / APRS capable


  • FT-7900R – Dual Band
  • FT-8800R – Dual Receiver / Cross Band Repeater
  • FTM-100DR – Yaesu Fusion Digital / APRS Capable
  • FTM-400DR – Dual Receiver / Cross Band Repeater / APRS capable / Yaesu Fusion Digital

Digital Modes
On the topic of Digital Modes. There are currently three competing standards. (Think VHS vs Betamax) or for you youngsters (BluRay vs HD DVD)

Yaesu has developed and released a system called Fusion. It’s based on C4FM.
Icom has had a system called D-Star for the last 10 years.
Motorola Has a system referred to as DMR, or MotoTRBO.

If my Crystal Ball is tuned properly, I think Yaesu’s Fusion system is going to end up being the winning technology for most average hams. I make no promises that this is correct. However looking at how unsuccessful Icom has appeared to be with D-Star, I think it’s unlikely they’re going to win the battle.

I think the EMCOM (Emergency Communication) crowd is going to flock to MotoTRBO/DMR. In large part because many of the ARES/RACES Emergency Communications types also work with Police/Fire/Search & Rescue Teams and are carrying Motorola radios already.

I didn’t mention Motorola radios above in my list. Motorola builds some exceptionally high quality equipment. However it’s all designed for use as Business Band Radios. They work fine in the Amateur Radio Service, and it’s legal for a Ham to use them as such. However I think anyone leaning toward a Motorola, is already experienced enough that they’re not looking for any advice from me. 🙂

Ham Radio Gear – Part 1

Mobile Radio Gear: (VHF/UHF only in this segment)
Radios for Overlanding fall into two major categories. Handheld Transceivers (HTs) and Mobile Radios.

Handheld Transceivers are effectively “Walkie Talkies” and can run from as inexpensive as $35 per unit for a Baofeng UV-5R all the way up to several hundred dollars for a top of the line Yaesu/Icom/Kenwood digital HT, like this Yaesu FT2DR. HTs typically offer several power settings, with Low being ~ 0.5W, medium being 1-2W, and high being 5W. At 5W the radios tend to get hot while transmitting a lot, and the batteries don’t last long. (It’s worth noting a CB maxes out at 4W in the United States…)

Mobile Radios come in three major varieties, and then have a host of options. The three major types of mobile VHF/UHF rig are:
Single Band (usually 2M)
Dual Band (usually 2M/70CM)
Dual Band CrossBand Repeater (usually 2M/70CM)
The single band radios are exactly what they sound like. These radios operate within a single band, which usually means 2M, although they don’t have to. These usually, but not always, output between 5w on Low Power and upwards of 75W on High.

A dual band radio is virtually identical to the single band radio, except you can select between two bands. This means if you’re in a small group, and if everyone has dual band, you can select which band you want to use. The 2M band is the most popular band in the world. If you’re looking for a quiet place to talk within your caravan, you might choose as a group to move to 70CM for instance.

Finally we have CrossBand Repeaters. These are also dual band radios, but they have two receivers in them, rather than one. This means they act in many ways as if you have TWO radios at the same time in your vehicle. These include a special mode of operation though, that allow you to “connect” the 2M radio to the 70CM radio. Thus, anything received on the 70CM side will be instantly re-transmitted on the 2M side. And anything received on the 2M side, will be re-transmitted on the 70CM side. When coupled with an HT, this can allow you to use the HT on 0.5W on 70cm, but communicate with a remote station using the 50-75W 2M transmitter in your vehicle. (Ask me about “Red River Gorge” in Kentucky sometime.)

Digital Mobile Radios Another newer entry into the Mobile, and HT ham radio market is Digital radios. These all operate normal FM like the others listed, however they include some form of digital encoding. Right now there are no “standards” so each vendor has their own competing protocols. Yaesu appears to have the most widely adopted system with C4FM FDMA and their Fusion Repeaters. This is a fairly in depth discussion on its own, and I’d be happy to field questions to the best of my ability but won’t muddy the waters here.

Like everything else in life, in many ways you do get what you pay for. I personally intend to pick up a few (5?) UV-5R radios to keep in a Pelican case in the truck for dire emergencies but wouldn’t personally trust them as a primary radio. Ham radio is like a lot of hobbies. There are many different ways to participate and enjoy the hobby. I’ve hardly scratched the surface here. I, and I suspect the rest of the Hams on Overland Bound, would be happy to field any discussion on the hobby you might have.
