HamRadioNow: MotoTRBOStar

Last night I uploaded HamRadioNow Episode 138. I’m calling it MotoTRBOStar because it’s about a newly announced handheld radio that will claim some firsts: it’s the first “dual-digital” mode radio (D-STAR; and MOTOTRBO, or generically DMR – Digital Mobile Radio); and it’s the first non-ICOM off-the-shelf radio to do D-STAR.* The episode is an interview with the CEO of Connect Systems, Inc., Jerry Wanger (rhymes with Ranger). CSI (isn’t that a TV show?) has been selling analog, trunked and DMR digital handheld radios in the commercial service. Recently, Jerry learned that a lot of hams have latched onto his radios for use on the ham-band MOTOTRBO repeaters. The radios are quite inexpensive, and apparently pretty high quality.

Jerry had a novice license long ago, but never mastered the code to upgrade. Side note: back in the 60’s, a Novice license ran one year and couldn’t be renewed.  And Novices had voice privileges on only one band: two meters. So Novices who spent too much time on two-meter AM (there was almost no FM then) and didn’t get their code speed up to 13 wpm for a General could get a Tech, but then they were confined to VHF/UHF. Again, repeaters were just barely getting started and were mostly unknown, so Techs were in a kind of Purgatory. But it was a way to keep licensed. Evidently Jerry didn’t choose that route. But he’s about to get re-licensed now.

So Jerry appreciates ham radio, and decided to make a model radio (CS700) that was more “ham-friendly,” with features like DTMF and the ability to program frequencies and parameters directly from the keypad. Then he decided to add D-STAR. That model, the CS7000, is planned for Fall release. He’ll be at Dayton to show it off.

Jerry does the software and designs the hardware specs himself, and has the radios manufactured in China. As he says, he can buy the finished radios cheaper than he can buy the parts.

So that’s all in the interview. Now I’ll wax a bit philosophical on the topic.

I’ve been a ham since 1965, WN9NSO, in the Chicago suburbs. And while I did play on two meter AM with a Heathkit Twoer (to the displeasure of my mentors, who warned sternly about neglecting the code), I also spent enough time in the 40 and 15 meter Novice cw bands to wick the speed up and pass my General after just a few months. And while I have almost always had a presence on HF, I’ve felt more at home on VHF/UHF. I was introduced to FM almost immediately. I had a Motorola 30D base station in my shack, and 80D mobile in my Dad’s car by 1967 (these were ancient, all-tube radios. The 80D even had a Dynamotor to power the transmitter). There were only two or three repeaters on the air in Chicago at the time. I was too young (and never an engineer) to be much of a leader at the time, but I watched the FM boom from a front row seat.

Fast forward to the early 2000’s. I’m editor of the SERA Repeater Journal, the magazine published by the SouthEastern Repeater Association, the group that does frequency coordination for 8 states. I come across a reference to D-STAR, and while I didn’t think much about it at the time, I did ponder a digital future in my column. But D-STAR wasn’t one of those flights of fancy that came and went. With ICOM behind it, D-STAR grew beyond it’s original 1200 MHz system as ICOM added radios for 144 and 440 MHz. Meanwhile, I had moved from editing the magazine to producing ham radio video on DVD as ARVN:Amateur Radio//Video News. I bought ICOM’s first D-STAR dual-band mobile, the ID-800, and handheld, the IC-91, and soon after produced a documentary titled Digital Voice for Amateur Radio. The DVD also featured a segment on HF digital voice, and a little on APCO-25, another VHF/UHF digital mode being adapted from Public Safety radio to Amateur Radio. I’ve written a few articles and reviews in QST on D-STAR and ICOM radios. I’m not the foremost authority on it by any means – I consider myself a journalist (with a side of pundit these days), not an expert – but I’ve learned a lot. And ham radio doesn’t have many pure journalists. Everybody’s involved.

D-STAR was met by hams with sharply divided reaction (and more than a few yawns). A few embraced it immediately (best thing ever). A few more were rigidly opposed (End Of Amateur Radio As We Know It). Most, if they were even aware of it in the early years, were more wait-and-see. Not gonna sink a lot of money into a radio that might not go anywhere. All the D-STAR radios were good Analog radios, too, but they were a few hundred bucks more expensive, so while the radio wouldn’t be useless, it would have been a costly experiment.

Turns out D-STAR has hung around and grown fairly quickly. It’s in most major and medium metro areas, and even some rural areas, of the US and many countries around the world. But there’s still plenty of territory that has had analog FM for decades but no D-STAR at all yet. Any long road trip will quickly bear that out. You’ll drive a long way between “islands” of D-STAR coverage. It’s very much like FM was in 1970 – available mostly in the larger cities. I remember being excited when driving toward Denver way back then. A mountainside repeater on 146.94 broke my squelch about 100 miles out after hours and hours of radio silence.

D-STAR proponents, and even us “objective journalists” (OK, I’m not objective on this) point out how much technology is going digital (TV, cell phones, a fair amount of two-way business and Public Safety radio) while hams have barely moved the needle, except for the all-text modes. Yeah, we led the way with Packet Radio in the 80’s (a few did, anyway… not most of us). But for a group that likes to talk more than anything else, our voices have remained mostly analog, right up to today. Digital has some advantages (signal to noise, voice+data, and spectrum efficiency), but they haven’t been compelling enough yet to get wholesale adoption. Except for D-STAR, they mostly haven’t been built-in to radios. And on HF especially, we don’t know how we’d use them for some of the core activities like contests and DX.

As we gaze outside of our pasture to that real world that’s growing increasingly digital, there’s another issue to note. Digital doesn’t stand still very long. Upgrades happen fast, and sometimes older stuff becomes obsolete – even unusable – pretty quickly. Analog TV made it about 60 years. Vinyl records a little longer. CDs aren’t dead, but sales went to nearly zilch, after about 20 years. On the Internet, where software and apps can be easily upgraded or replaced, we’re talking a few years or even months. Remember “RealTV”? And you know that 70″ 1080p High-Def TV you just got. Obsloete. Here comes 4k. Then 8k. Broadcast TV stations are going nuts trying to figure out to squeeze that into their “Advanced” television system. **

I’m about to edit my next HamRadioNow that I recorded yesterday with Bruce Perens K6BP. Bruce is a serious open-source guy, so he never had a great love for D-STAR. Bear that in mind when he declares it obsolete. Objectively, things in ham radio move slower. Whenever there’s fixed hardware involved, upgrades can’t happen that fast – it costs too much. But D-STAR is 15 years old, and better technology is available. Yaesu claims their new C4FM “System Fusion” is “better.” Bruce disputes that, and I don’t have the background to determine it for myself. But I can say that if Yaesu is correct now, what can they say in 5 years (0r 5 months) when the next something better comes along?

Bruce is involved in a couple of projects. For HF, there’s FreeDV, and for VHF/UHF, it’s the “HT of the Future.” Both are based on the open-source CODEC2, which is still very much under development, and always will be, at least for the foreseeable future. Today, FreeDV is a sound-card mode that you can run much like PSK-31. Tomorrow, you might punch it up on the mode switch (Flex will probably be the first radio to have that option). FreeDV – and probably a lot of new modes – will be upgradable by downloading software. I won’t say it will never be obsolete, but it’s the kind of thing that will move us from being slow-moving dinosaurs tied to our fixed-technology hardware, into a more nimble future where we are not walled off from each other by incompatible modes. All this stuff is coming up in HamRadioNow Episode 139, as soon as I can stop typing here and get back to editing it (maybe tomorrow or Monday).

Ya know… I’ve never operated FreeDV or it’s predecessors (FDMDV, WinDRM) that I featured in Digital Voice for Amateur Radio. I don’t have a computer sitting next to my HF rig… at least not yet. All my computers are busy doing something else. But I’ll find one soon, and give it a try.

* Devices like the DVDongle are cool, but they’re not standalone radios. There are a few modules that you can use to turn an analog radio into a D-STAR radio using its 9600 packet port, but that’s not off-the-shelf. The NW Digital radio might lay claim to being the first non-ICOM commercial D-STAR capable radio if it reaches production before the CS-7000 does, and right now it’s a race. But while it will do D-STAR’s DV voice mode, it’s really designed as a multi-mode platform for medium-speed data, using D-STAR’s DD mode and many others. It will have exciting uses, but it’s not your grab-and-go handheld or mobile radio.

** My career has been in the audio/video production business, mostly making commercials. I quickly learned a lesson: never stick a label on anything that calls it “new.” And never call anything “final.” OK, sort of two lessons.

The “new” lesson came from a reel of alignment videotape that we used at a TV station I worked for. You had to run that through the old 2″ “Quad” videotape machines to align the heads before making a recording, so the reel got used several times a day. It started life as a 5-minute piece of tape, but every time you used it, you’d then rewind it and thread a piece of blank tape for recording onto the machine. That rewind was high-speed, and if you didn’t catch it fast enough, the end of the tape would flap like crazy, and get frayed. You had to cut the frayed piece off lest it get caught in the high-speed spinning video heads next time, clogging the hell out of them and maybe ruining a head assembly that cost tens of thousands of dollars to replace. The boss would be very angry.

When I started working at the station, that alignment reel had about 45 seconds of tape left on it, having had a half-inch of frayed end cut off many, many times. And the flange was grimey from all the hands that had loaded it on the machines over the years. But there beneath the grime, just barely readable in faded Sharpie, were the words that some engineer wrote just after he took that reel out of the box for the first time: Alignment Tape. 5 min. NEW.

    “The radios are quite inexpensive, and apparently pretty high quality.”

    And where do we find the prices for the “quite inexpensive” radios? I’ve been to the linked site in this post and I can’t find pricing. And who says these radios are “apparently pretty high quality”? Reviews, posts, threads – links please?

  • Rob AA6RA:

    Here is a link to another interview with a little more information regarding price and availability. It seems he wants to keep the price under $250.00 but does not have firm figures because he is still ironing out manufacturing. He is hoping to have a prototype available at Dayton 2014 so you won’t find any reviews as of yet. Hope this helps.

    “And where do we find the prices for the “quite inexpensive” radios?” Jerry gave the price of the CS700 as $180, if I recall correctly. That’s his wholesale price that he’s selling the radio for to hams. Retail is $280. That’s not the CS7000 – he didn’t give a price for that, but you can see the previous response give the $250 ballpark. As for quality, I’m roughly quoting from an Charlotte area D-STAR/DMR mailing list where several members were raving about the CS700. In the program, Jerry claims very high quality, and I note that when the radio is produced, it will be reviewed by many hams on many sites, and we’ll really know only then what the build quality is. Jerry also lists a couple of independent Yahoo groups that have commented on the CS700. I’d love to have time to do a ton of independent research and pull out links to everything, but I don’t. I encourage viewers to add that value to the programs. I have a “HamRadioNow” Yahoo group that would be a good place for that, but you’re welcome to do it here if you prefer.
