None of these were intended for field use up to about 1980 or so, therefore they would not have undergone full environmental testing. Consider them "COTS" (Commercial Off-The- Shelf) equipments as described by Hans. Let me put it this way. If you are going to design a product for the military, (And you must admit military contracts are the "800 pound gorillas" in the business). Since I've actually designed military equipment, last one being the AN/ASM-416, a test set, I just don't see that "gorilla" label. Specifications are sometimes tough to meet and nobody can talk their way out of it (as salesmen or executives do) to project overseers. You either meet specifications or you get fired. I always met spec. I don't think I could define military contract work because so many hams just haven't done it and they are all full of misconceptions. It is just WORK. If you like it you get paid for the fun. If you don't like it then you probably wouldn't have gotten high enough on the totem to be in a design position. And by simply tweaking a tuning slug it will work as well on the ham bands.. and the device is not "Classified" in and of itself. The MAJORITY of military contract work is NOT classified. Hasn't been for decades. The major 'classified' category is "company private" which is common, very common to all corporations, amounting to not jabbering company stuff to workers in other companies. Yes, I've been vetted by the FBI and a bunch of other alphabet soup agencies up to Secret with a background check (actual interviews in-person) for Top Secret. Missed a "Q" clearance completion because my work assignment change to another group. ['Q' was a classification involving nuclear things] Forget the Hollywood BS about security clearances, drama, and that phony baloney. I live near "Hollywood" and very, very few of those were actually involved in such national secrets. The only ACTUAL encounter close to me was the Lockheed "Skunk Works" at Burbank airport (now renamed "Bob Hope"), at Building 82 just off the Hollywood Way and Winona intersection in Burbank, CA. Drove past it for years and years without knowing it was THERE all the time since WWII days. A mile and a half from my house of 37 years, I had to find out its location from a book, a biography of Ben Rich, successor to legendary Kelly Johnson, read several years after Lockheed pulled out of Burbank. Why not market to hams as well? Ahem...Collins Radio tried that but it wasn't profitable. Hallicrafters went bust long ago. National Radio quit the ham market long ago. SGC in Washington state markets HF SSB transceivers mainly to private boat owners but isn't pushing for the ham market. Face it, HF radios are NOT in the market spotlight anywhere except to hams and the Big 3 in Japan have that tied up nice and tight. The market for NEW radios is at VHF - UHF - Microwave, strong emphasis being at 1 GHz for cellular telephony...both cell sites and mobliles. Its been that way for over two decades. Now, I do admit that the military has some classified stuff that I'll likely never set eyes on.. Not that much. When I was stationed in Japan my battalion had full run of everything but the Crypto room in the sub-basement of the Far East Command Hq building...and guys who manned that were battalion personnel. The reason so few see things is because it isn't publicized and it has no "action" by itself. To see a 1962 booklet produced by the Army on one big station: http://sujan.hallikainen.org/Broadca...phabetSoup.pdf http://sujan.hallikainen.org/Broadca...s/My3Years.pdf Both are about 6 MB file size and the second one is my photo essay of a 3-year assignment at the same station 1953-1956. Good contrast between essentially WWII gear and better stuff working 15 years after WWII was over. [on KWM-2s] Perfectly good ham radios were being totaly reduced to their atoms because they were part,, Mind you just part, of a classified communications system. No, no, no...MARS wasn't used for "classified" comms in Vietnam. I can assemble a list of what was used - there's plenty of sources of history on that other than ARRL publications. BTW, the KWM-2 came in two flavors: Full-frequency range for maritime market, limited range for the ham market. AN/FRC-93 designation was for the maritime market KWM-2. Never mind that they were a part you could buy over the counter at Ham Radio Outlet.. they were still part of a classified system so they were blown up, drilled, shot, flamed, run over with tanks and otherwise redced to powder. Then visit Davis-Monthan AFB (?) to see square miles of "perfectly good aircraft" that haven't been recycled for their aluminum, outdated engines or outdated internal mechanical, hydraulic, electrical systems. A total waste of thousands of dollars worth of hardware that could have been sold, without danger of compromising the classified system at all since this was just a part. WAR by itself is a TOTAL waste of lives and property. What else is new? Regardless of the tales from over 35 years ago, MARS was NOT handling "classified" material into/out-of Vietnam. The classified material was encrypted by a small group of personnel and could be sent over very ordinary radio circuits using very ordinary radios. First operational in 1989, the AN/PRC-119 (manpack version SINCGARS) can be captured and reverse-engineered to try to find its built-in encryption system for decoding intercepts. Won't help anyone. The digital voice and data modulation uses a long long key and the carrier hops at a 10 frequencies per second rate over a 30 to 88 MHz span. "Hopsets" (colloquial) are generated at battalion Hq level for all that encryption-hopping key information. It is difficult as heck to INTERCEPT enough message data to attempt a decrypt attack on it. ITT Fort Wayne, IN, has manufactured over 300,000 SINCGARS radios since 1989 (ITT press release some years ago). What are you going to do with a VHF radio that doesn't even have a tuning knob on it? 73, Len K6LHA |
