MORE RS-1/RT-3 MWO DATA; Pete McCollum MEMBERS WRITE; More AM-26/AIC & Interphone Amps, Radiac-PDR-18 & Others, NEW MEMBER; Roy Morgan HUMOR; *********************************************** ANNOUNCEMENTS; New Regular Column? I have an idea for a new regular column to be titled "Eat Our Hearts Out; John Doe's Collection". Here members might list all the items they currently have in their collections, along with a legend that will indicate the status of that item, and further your efforts to supply it's support. Additionally it is hoped that some cross modulation might occur between members with like equipment, and needs both data, and material. It is understood that some members may not wish everyone to know what's in their posession, nor their address. It will be a simple mater for me maintained your anonymity, and allow your screening of any possible correspondence that might result. The size of your submission does not matter, but it will only be posted once unless there is a significant change in it's status. This column might follow a format such as below: EAT OUR HEARTS OUT; Dennis Starks' Collection Legend: [@] need historical info [#] second unit wanted [+] need manual [*] need accessories [&] need parts BC-222,*+ BC-620,* BC-728,Italian BC-1000,French BC-322,*+ BC-654,#&*+ BC-745,#&*+ BC-1306,#&*+ BC-348 BC-659,* BC-778,+ BC-1335,* BC-474,@#*&+ BC-721,#&*+ BC-1000,U.S. BC-669, * BC-611,* BC-728,U.S.* BC-1000,Navy ATC,*+ MAB,@ RCB,@* TBX-8,&*+# DAV-2,@# MAR,+ ART-13,*+ RBZ,@# TBY-2, TCS MAY-1,@+ What do you think? Any ideas? Maybe include the state that your in so that possible future meets with other members might be speculated on? Thanks, Dennis *********************************************** MORE RS-1/RT-3 MWO DATA; Pete McCollum Here's some more tedious details related to "MWO 39": I remembered that a couple of my RT-3's came with a wire jumper installed between the 'Rcvr Ant' post and ground (the jumper is a piece of tinned #14 wire, bent into a "U" shape so that it will go through both binding posts). It occurred to me that this must have the same effect as the diodes. So, I re-read the RS-1 manual, and sure enough, it says that the jumper must be there when you don't have the rcvr connected: "Failure to do this, reduces the effectiveness of the key click filter". The next paragraph goes on to say that you should NOT use an external key if the rcvr is connected to the Rcvr Ant post on the xmtr, because: "The loop impedance of the leads to the key may allow enough RF voltage into the receiver to cause damage to the first tube and antenna coil. An external key is not recommended if maximum freedom from key clicks is important." So, adding the diodes (MWO 39) would have two purposes: - Avoid a key-click problem when a rcvr is NOT connected (and no need for the external wire jumper); - Avoid damaging the rcvr when an external key is used. For us collector-types that worry about making everything look "correct": If your RT-3 does not have the "MWO 39" marking, then it should have the jumper installed. BTW, the difference between a PRC-64 and PRC-64A is to add about 5 components (including two diodes, I think), to improve the keying. Pete *********************************************** MEMBERS WRITE; More AM-26/AIC & Interphone Amps > ed) The AIC-2 is listed as a "high altitude"(40,000ft) system used by > interceptor-fighters and light-medium bombers. As of 1958 it was listed > only as a "Limited Standard" in use by the Air Force so it would appear > its postwar replacement was fairly quick (possibly by the Magnavox > AIC-4). Right on, Dennis. Part of the rig here is a growing collection of airborne interphone sets to go with the equipment they served. The AIC-2 was a transition piece to replace the RC-34/35/36/51/175 set, which used the BC-347 as its main amplifier. Introduced in late 1944, it looks like it was quickly overtaken by the AIC-4, which had a smaller footprint and was apparently more reliable. Both the AM-26/AIC-2 and AM-40/AIC-4 had altitude compensation, which raised the volume level as altitude was increased - the AM-26 being manually adjusted, the AM-40 automatic through a barometric switch. The Navy skipped over the AIC-2 to the AIC-4 as a replacement for their venerable RL-* amps, so only the AAF appear to have been (brief) users of the AIC-2 (not to be confused with the AIA-2, which *was* a contemporary Navy interphone system.) The AM-40 amp, which incidentally is listed as part of the 1945 and later ARC-5 set, seems quite rare today - though it went through a long career of several versions, including a small transistorized -B model housed in a BC-1366 sized box. I've been afraid to hook that version up, concerned about the ionic contempt effects from all the toob equipment nearby... The AM-26 looks more command set-like than the AM-40, though, and would be entirely appropriate for an SCR-274N set. Lots of the AM-26s were surplussed at the end of the war, which explains the conversion articles to turn them into "hi-fi" amplifiers (which they were not!) A variety of jack boxes (another part of the collection) were shared between the RC-**, AIC-2, AIC-4, etc., depending on the Service involved, so you'll see the BC-366 and 1366 paired with interphone amps up through AIC-5 and beyond. BTW, the AIC-5 is a real beast with five independent channels, having two command receiver dynamotors on the back, in a full B1-D1 ATC enclosure. It appears to have been physically the largest of the airborne amps. If anyone runs into a manual for it, I'd appreciate a copy. The amazing thing about the interphone sets is their diversity! Sorry - digression is my strong suit... :-) 73, Mike Hanz KC4TOS ---------------------------------------------------------------------------------- Radiac-PDR-18, Bill, I used to have a PDR-18, which is a SS unit with a high scale that goes up to 500 Roentgens/hour !! That's serious radiation! It's most-sensitive scale was way more rads than I would ever run into (I was interested in measuring output from radio dial markings, etc.). As I recall, it ran from "D" batteries. Pete ed) Here are a few as listed in PAM-310-4 1973. PDR-T1B, PDR-27, 27-C, -27E, -27G, -27J, -27L, -27M, -27P, -27Q, -27R PDR-39, -39A PDR-53 PDR-54 PDR-60 T-290A NAVSHIPS 900,177(A) 1856, Field Change Index List: PDR-5 PDR-8 PDR-18 PDR-27 I'm sure Fed Log would turn up more, but my CD drive is still down. *********************************************** NEW MEMBER; Roy Morgan Dennis, I'd like to participate in your radio, etc. activity. #1. I accept the contitions you sent in your e-mail. #2. ( ... yourself, your current interest): I'm a graduate electrical engineer (Tufts, 1966), former Navy helicopter Pilot (ASW, Atlantic), and active ham (K1LKY since 1959). My interests are in military communication receivers, toobe type mostly, and transmitters of the tube era. My collection includes R-390A's, National, TMC and Hammarlund receivers, a Johnson Valiant and Ranger. My second major hobby is photography, and the house is equipped with a darkroom. I own two military transmitters of interest: a PRC-2(?) 243 mc survival beacon transmitter, and a clandestine RT-1B transmitter (1950). I'm currently gathering information about the RT-1B. I also have a 1944 Navy GO-9 aircraft HF transmitter. Wanted: A Collins PTO for the R-390 VLF receiver, model 70-H1. I offer as a finders fee to repair and align any R-39X receiver. I also want to find an inverter for the GO-9 (28 volts to 115vac 800 cycles). Trade: I have two ARN-6 ADF receivers. Will trade one for a rack or rear connector and conrol box with cable to get the other one running. Assistance: I have lots of test gear and experience for alignment/repair of equipment. Can also do high quality photography of equipment. I am in the Washington DC area, near the Historical Electronics Museum and the Crypto Museum, and would be able to do a limited amount of research for someone who can't get to those places. ---Roy Morgan K1LKY since 1959 Hydrodynamics/Hydroacoustics Technology Center Naval Surface Warfare Center, Carderock Division ed) It would appear you might have the only surviving example of a PRC-2. We're gonna hafta do some serious hagglin over it, as I ain't got one, and that's not acceptable. *********************************************** HUMOR; Military differences An Army grunt stands in the rain with a 35 lb. pack on his back, 15 lb weapon in hand, after having marched 12 miles, and says, "This is shit." An Army Airborne Ranger stands in the rain with a 45 lb. pack on his back, weapon in hand, after having jumped from an airplane and marched 18 miles, and says with a smile, "This is good shit!" A Navy Seal lies in the mud, 55 lb. pack on his back, weapon in hand, after swimming 10 miles to shore, crawling through a swamp and marching 25 miles at night past the enemy positions, says with a grin, "This really is great shit." A Marine, up to his nose in the stinking, bug-infested mud of a swamp with a 65 lb. pack on his back and a weapon in both hands after jumping from an aircraft at high altitude, into the ocean, swimming 12 miles to the shore killing several alligators to enter the swamp, then crawling 30 miles through the brush to assault an enemy camp, says, "I love this shit." The Air Force NCO sits in an easy chair in an air conditioned, carpeted office and says, "My e-mail's out? What kind of shit is this?" ---------------------------------------------------------------------------------- In an effort to ensure proper training and readiness among the military services, Congress has approved the following changes to basic principles of recruit training: HAIRCUTS: Marines-heads will be shaved. Army-flat-tops for all recruits. Navy-no haircut standard. Air Force-complete makeovers as seen on the Jenny Jones show. TRAINING HOURS: Marines-rise at 0500, train until 2000. Army-rise at 0600, train until 1900. Navy-rise at 0900, train until 1100, lunch till 1300, train until 1600. Air Force-rise at 1000, breakfast in bed,lunch at 1200, nap at 1400, training ceases at 1500. MEALS: Marines-Meals-Ready-to-Eat 3 times a day. Army-one hot meal, 2 MRE's. Navy-3 hot meals. Air Force-catered meals prepared by the Galloping Gourmet, Julia Childs and Wolfgang Puck. All you can eat. LEAVE and LIBERTY: Marines-none. Army-4 hours a week. Navy-2 days a week. Air Force-for every four hours of training, recruits will receive eight hours of leave and liberty. PROTOCOL: Marines-will address all officers as "Sir" and refer to the rank of all enlisted members when speaking to them (i.e. Sgt Smith). Army-will address all officers as "Sir", unless they are friends, and will call all enlisted personnel "Sarge." Navy-will address all officers as Skipper, and all enlisted personnel as Chief. Air Force-all Air Force personnel shall be on a first name basis with all other personnel. DECORATIONS/AWARDS: Marines-medals and badges are awarded for acts of gallantry and bravery. Army-medals and badges are awarded for every bullet fired, hand grenade thrown, fitness test passed, and bed made. Navy-will have ships' engineers make medals for them as needed. Air Force-will be issued all medals as they will most likely be awarded them at some point early in their careers. CAMOUFLAGE UNIFORMS: Marines-work uniform, to be worn only during training and in field situations. Army-will wear it anytime, anywhere. Navy-will not wear cammies, they do not camouflage you on a ship. Captains will make every effort to TRY to explain this to your sailors. Air Force-will defeat the purpose of camouflage by putting blue and grey service chevrons and name tapes on them. CAREER FIELDS: Marines-all Marines shall be considered riflemen first and foremost. Army-doesn't matter, all career fields promote to E-8 in first enlistment. Navy-nobody knows. Navy still trying figure out what all the SMC, BNC, BSN, and all the other ratings things are. Air Force-every recruit will be trained in a manner that will allow them to leave the service early to go on to higher paying civilian jobs. ---------------------------------------------------------------------------------- An Arab has spent many days crossing the desert without finding a source of water. It gets so bad that his camel dies of thirst. He's crawling through the sands, certain that he has breathed his last, when all of a sudden he sees a shiny object sticking out of the sand several yards ahead of him. He crawls to the object, pulls it out of the sand, and discovers that he has a Manischevitz wine bottle. It appears that there may be a drop or two left in the bottle, so he unscrews the top and out pops a genie. But this is no ordinary genie. This genie appears to be a Hassidic rabbi, complete with black alpaca coat, black hat, side curls, etc. "Well, kid," says the genie. "You know how it works. You have three wishes." "I'm not going to trust you," says the Arab. "I'm not going to trust a Jewish genie!" "What do you have to lose? It looks like you're a goner anyway!" The Arab thinks about this for a minute, and decides that the genie is right. "OK, I wish I were in a lush oasis with plentiful food and drink." ***POOF*** The Arab finds himself in the most beautiful oasis he has ever seen. And he is surrounded with jugs of wine and platters of delicacies. "OK, kid, what's your second wish." "My second wish is that I were rich beyond my wildest dreams." ***POOF*** The Arab finds himself surrounded by treasure chests filled with rare gold coins and precious gems. "OK, kid, you have just one more wish. Better make it a good one!"After thinking for a few minutes, the Arab says: "I wish I were white and surrounded by beautiful women." ***POOF*** The Arab is turned into a Tampax. The moral of the story is: Be careful of what you wish for. There may be astring attached. ---------------------------------------------------------------------------------- A three-year-old went with his dad to see a litter of kittens. On returning home, he breathlessly informed his mother there were two boy kittens and two girl kittens. "How did you know?" his mother asked. "Daddy picked them up and looked underneath," he replied. "I think it's printed on the bottom." *********************************************** (The preceding was a product of the"Military Collector Group Post", an international email magazine dedicated to the preservation of history and the equipment that made it.
