MILITARY COLLECTORGROUP POST, JAN.23/98 INDEX; WHAT TEST EUIPMENT TO GET? MORE FROM RUSSIA; OUR NEWEST GROUP MEMBER; BILL'S WHATSIT'S, NOW WE KNOW; HUMOR; **************************************** WHAT TEST EUIPMENT TO GET? Dennis, Please put this question to the group. I have been collecting radio test equipment from the 1950's with the intention of making a display that would represent the radio test equipment used by Signal Technical Intelligence to evaluate captured enemy radios. Thus far I have collected the following items: Tube tester I-177-B Tube socket adapter Volt - Ohm meter I-166 44-52 Resistance Bridge ZM-48 Freq Meter Set I-129 (B) [plug in coil/capacitor set]Coils/cap box only, thus far. Multimeter ME-77 C/U Grid Dip Meter Test Oscillator TS-47A/APR (ORDER 28780-PHILA- 55) Now what other equipment could be used for this type of work. Remember the time frame is 1950-1960. Any suggestions, comments, recommended additions, deletions would be appreciated. Anybody who has anything that would fit in this type of display that is excess to their needs, let me know. Thanks, Bill Howard THE WILLIAM L. HOWARD ORDNANCE TECHNICAL INTELLIGENCE MUSEUM e-mail wlhoward@gte.net Telephone AC 813 585-7756 ------------------------------------------------------- ed) you'll need a couple signal generators, one for LF-low VHF, another for VHF, my personal choice would be the URM-25 & 26 respective. The most used multi meter from WW-II till the early 80's would be the ME-6. The most representative scope would be an OS-8 & wont take up much room in the display. Two frequency meters, one for HF, the other VHF, a BC-221 would be fine for the HF. A test receiver was also very common in this role, the Hallicrafters S-36/27 family which includes several variants having both commercial & military data plates were available, and recommended by name in vintage manuals. I missed one of these last weekend at the St. Joe hamfest. The above items would be the most common, and recognized by any museum patron, or veteran, also they'd all be space, and price conservative in the event you have these problems as most of us do.You can look in any vintage radio service manual for more ideas, they all have a recommended service equipment list. **************************************** MORE FROM RUSSIA; Dennis, Please put this in the next group posting. My Russian HAM contact has two more Russian Radios and he sent line drawing pictures of the sets. They are: R 143 "BAGULNIK' CW/SSB/RTTY 1.5 to 20 Mhz, size 105mm x 310mm x 350 mm, 7kg in weight and has headset, mike, whip antenna, key and technical manual. VRP 60 Political Commissars Agitation Receiver of the Red Army. Made in the 1950's, it looks to be a sort of troop entertainment radio that doubles as a public address system. Powered by AC or DC batteries.. Has a built in speaker. He says that it works. I assume that you just plug it in and turn it on. It weighs 8 kilograms. If anyone is interested, please have them get in touch with me. I will send copies of the drawings and get any follow up information that I can. ------------------------------------------------------------ My Russian friend has offered to trade tubes, He can offer 4CX800(GU74B)power tetrodes for Alpha Beta-91 ham power amplifiers, NIB, as a swap against new Eimac/French/Svetlana 3-500G/Z/ZG power triodes; one 4CX800 for two 3-500 tubes.He said "I stand behind my tube and give a warranty. 3-500 with carbon round turned plates preferred."

Theodore Benjamin (no callsign yet) was born at 8:55 AM Wed. 21 Jan. Mom and baby are doing well. My thanks to all of you who have expressed warmest wishes while we awaited his arrival.

And that yer success in other endeavors can be manifest in such a manner. So wheres the cigar!!?? Dennis **************************************** BILL'S WHATSIT'S, NOW WE KNOW; > I was rearranging a closet and ran across a black box special. > Some one has filed away the nomenclature. It is black wrinkle finish, > about 10" x 6" x 6 1/2". Has a switch on top marked on/off which has a > red data plate around it. Above the switch is what appears to be an > antenna connector. Front and back covers have 2 twist off screws which > allow the covers to be removed. One one side must be the battery > compartment. Has four plugs, two 2 pin plugs and two 3 pin plugs. > I suspect it is some sort of frequency generating device for > calibrating something. It is Serial No 8100:CPY. It has an Order No of > 9245WF43 which I assume means Wright Field 1943. > Do you have any idea what it is? Does anybody need one of these? > I would put it in the for trade list but do not know what to call it. This is the TS-1/ARR-1. Used to calibrate the ZB-3, ARR-1 and ARR-2 homing receivers up in the 200+MHz range. Normally comes with a white canvas cover like the one on the ZB/ARR-1 (it was "secret", don't ya know...couldn't have the unwashed masses seeing its complex design!) :-) Most of the ones I've seen have the nomenclature ground off - must have happened when they surplussed them. Has two 955 triodes in a modulated oscillator. 73, Mike H. AAFRadio@erols.com What Bill describes matches the TS-1/ARR-1 that I have. It's a test oscillator that produces a VHF (around 300 mhz) signal that is modulated with a broadcast-band signal. This "double-modulated" signal can be detected by the ARR-1 and ARR-2 receivers, etc. Here's a description of mine, which has a complete ID plate and schematic: It's metal with a black krinkle finish, the two opposite sides are removable via dzus fasteners. Under one side is the battery compartment (about 1/2 of the total space). Runs on 90V and 6V. Contains two acorn triodes - one is a VHF osc that uses a tunable cavity (?). The cavity is about 2" dia by 10" long, made of copper or brass. The other acorn seems to be an HF osc (BC band?), using a tank circuit inside an aluminum can - looks like a large IF can. There's a handle on the top of the box, and tied to the handle is a little cloth bag than contains a wrench for adjusting the two tuned circuits (one end adjusts the screw on the cavity, the other end is for the HF coil). There's a schematic on the inside of the lid, with the title: "PORTABALE TEST OSCILLATOR" - notice the spelling of the word 'portable'! The ID plate on the top of the box says "*TS-1/ARR-1" (the * is a star), serial # 7566 :CPY, order # 9245-WF-43. Inside the lid is a holder for a whip antenna (about 6" long), which connects to the RF connector on the top. The only other external control is the power switch. I would be interested in trading for another one, if I have something that you want... Pete -------------------------------------------------------------------- Do you have any information on a test oscillator: > Test Oscillator TS 47A/APR (ORDER 28780-PHILA- 55) > I just got one, would like to get some background/details on it. Assume > the Order No places it about 1955 vintage. > > Bill Howard This oscillator is used on the AN/APR-4 countermeasures RX for calibrating the tuning units. Was originally introduced in WWII, but the APR-4 had such a long life, I'm not surprised at such a contract date. 73, Mike H. AAFRadio@erols.com I saw you were looking for info about the TS-47A/APR. The TS-47/APR is class A general radar test equipment. It's a test oscillator designed for testing of search receivers. Checks frequency operation and alignment. Used to test AN/APQ-14, AN/APR-1, -2, -4, and -5, AN/ARC-1, AN/ARQ-5, -8, -9, and -10, AN/ARR-5 and -8, SCR-587-A. Freq range is 40 to 115 mc and 115 to 500 mc, with usable output up to sixth harmonic (3000 mc). I don't know how much the A version is different from the original. I have manuals for the TS-47/APR, but not the equipment. Regards, Mike B. mblom@mail04.mitre.org **************************************** HUMOR; A small town prosecuting attorney called his first witness to the stand in a trial--a grandmotherly, elderly woman. He approached her and asked, "Mrs. Jones, do you know me?" She responded, "Why, yes, I do know you Mr. Williams. I've known you since you were a young boy. And frankly, you've been a big disappointment to me. You lie, you cheat on your wife, you manipulate people and talk about them behind their backs. You think you're a rising big shot when you haven't the brains to realize you never will amount to anything more than a two-bit paper pusher. Yes, I know you." The lawyer was stunned. Not knowing what else to do he pointed across the room and asked, "Mrs. Williams, do you know the defense attorney?" She again replied, "Why, yes I do. I've known Mr. Bradley since he was a youngster, too. I used to babysit him for his parents. And he, too, has been a real disappointment to me. He's lazy, bigoted, he has a drinking problem. The man can't build a normal relationship with anyone and his law practice is one of the shoddiest in the entire state. Yes, I know him." At this point, the judge rapped the courtroom to silence and called both counselors to the bench. In a very quiet voice, he said with menace, "If either of you asks her if she knows me, you'll be jailed for contempt!" ------------------------------------------------------------ This is from an actual trial in the UK. A young woman who was several months pregnant boarded a bus. Then she noticed a young man smiling at her she began feeling humiliated on account of her condition. She changed her seat and he seemed more amused. She moved again and then on her fourth move he burst out laughing. She had him arrested. Then the case came before the court, the young man was asked why he acted in such a manner. His reply was: When the lady boarded the bus I couldn't help noticing she was pregnant. She sat under an advertisement which read "Coming Soon: The Gold Dust Twins", then she moved under one that read "Sloans Liniments remove swelling". I was even more amused when she sat under a shaving advertisement which read "William's Stick Did The Trick". Then I could not control myself any longer when on the fourth move she sat under an advertisement which read "Dunlop Rubber would have prevented this accident." The case was dismissed. > ----------------------------------------------------------- **************************************** EDITOR; Dennis Starks; MILITARY RADIO COLLECTOR/HISTORIAN military-radio-guy@juno.com
