I had about 25+ years ago picked up this old WW2 4 cyl generator a PU-35/U , remember it had about 8 hours on the hour meter, it might have about 9 when I got it I fired it up, had it outside in a box, would like to get rid of it if anyone would be interested, can send some pictures. Im also in agreement to not drill holes or modify per the surplus conversion handbooks radio was using frequencies up to 450 MHz, and radar was using frequencies of 1 GHz . Most places cant scan books without destroying the original unless you pay a fortune. It could receive its output. [3], Torn.Fu.k: A HF transceiver. There are also other frequencies allowed based on location (Hawaii, Los Angeles, and the Grand Canyon). This receiver is part of a series of radio gear known as ARC-5 command sets, which describes an entire class of WW2 transmitting and receiving equipment for aircraft-to-aircraft communication. Amazing for resistors built before February of 42. Or both? Lots of good DX. The first decade of FM broadcasting, starting in 1936 to 1946, occurred in the 42 - 50 MHz band. << /S /GoTo /D (subsection.5.2) >> You might enjoy this video on reconditioning a WW2 aircraft radio that was converted to civilian use. It led to my career in electronics. Anyone, anywhere in the world can listen in, simply by tuning a radio to the frequency 4625 kHz. I used to be all about modding things to unrecognizability but that was when new gear was so much more expensive. magopeter liked Flipper Zero Multi-tool Device for Hackers. At this point I had two toggle switches and a pot with a mess of wire shoved into the rear panel connector pins. I made the necessary repairs; it appears that this unit was dropped at some point and the fixed plates, which were normally electrically isolated from ground, had popped off of their plastic insulators. No replacement of any components whatsoever. First order of business was to accurately test the capacitors because it was obvious that some were not functioning to spec. It was usually used with a two-metre antenna. Radios in 1942 were large, power hungry, and expensive. Of course, they called them megacycles, rather than MHz. June 1940. It is tough to test capacitors correctly, it requires multiple tests to troubleshoot for bad capacitors: Given all of that, the keys to troubleshooting tube equipment are to test the capacitance of each cap to verify that it is functioning and test the leakage to make sure it is not leaking current between circuits. Admittedly, OCR isnt going to be useful for photos, diagrams, and symbols, but in most cases even raw camera images will be far more useful than not having the data at all. (Tactical Information \(non-coded\)) Something was not right with it, the plates on the large variable tuning cap were literally grinding against each other. My elmer was a B17 radio op. If I have to restuff a capacitor because its failed, in my book that means I am fitting a new component. (LUF \046 MUF) 33 0 obj Which one was this radio used it? To check for value and leakage with one test device you must resurrect an old piece of test gear known as the capacitor checker. On this Wikipedia the language links are at the top of the page across from the article title. Over the next three years the contracts given the CPNAB grew to be the largest contractual award in history. Navy, 1946:139). (Very Low Frequency band, VLF). American ingenuity in developing strategies that maximized the impact of their planes strengths and minimized the consequences of their weaknesses was a key factor in stopping Japanese expansion in 1941. sorry guys. In order to begin the easter egg walkthrough, you need to first get a message from the Russian Army by setting the radio on Main Street to the right frequency. During night time contacts the lower frequency crystals should be used. WWII WW2 BC 611 HANDIE WALKIE TALKIE US Army Radio Reciever Top plate $79.99 $11.99 shipping Pre-WW2 US Army Military Signal Corps Field Phone Radio Telephone Type EE-3-B $429.99 $42.00 shipping or Best Offer Vintage WWII Army Signal Corps BC-603-D Field Radio Receiver Western Electric $199.99 $53.79 shipping I tend to have such a bad opinion of caps made since the mid 90s though, that I figure if I leave something in that seems marginal it still might last 5 years whereas a replacement might last 3. The time station is WWV on 2.5 MHz exactly. The system would also require a transmitter building at the bottom of the valley, placement of anchors at the ridge of the cliffs, wires running from the anchors to the transmitter, and a copper grid system in the valley to assist in conducting the signals. << /S /GoTo /D (subsubsection.4.4.1) >> Thereafter version b1 was used by the Pioneers. SO glad that the seller didnt touch it and you kept it as stock as possible! There are plenty. The basic wireless invention went through a rapid evolution between the first and second World Wars. First Responders Interoperable Radio System Team (FIRST) Trunking System Profile .

FuG 9: A transceiver, operated in the 0.1 - 7.1MHz (100kHz - 7100kHz) range. << /S /GoTo /D (subsection.4.4) >> One of the forerunners for this technology was the revolutionary electrical musical instrument developed by Leon Theremin. In other words, how much series DC resistance does a capacitor present when it is measured at a relatively high frequency. The Beginning of a Legend, Collins Radio and the ART-13. Fug 18: Group of radios covering 25 - 77.1 Mhz Fug 19: A transceiver operating in the range 3 - 7.5 Mhz. With the outbreak of World War II, radio communication stations in Hawaii were built as rapidly as all other military operations that combined to make the Pacific offensive. It was used for communication back to the regimental command post. Torn.Fu.i: A HF transceiver. It operated in the 19,990 to 21,470kHz (19.99-21.47MHz) frequency range with a transmission power of 5 Watts. B^), Great job! << The nice thing about tube gear is that when the power is turned off the tubes present an open-circuit and therefore you can test resistors reliably in-circuit without removing them. (Introduction) (BBC Radio Signal Prediction) endobj Two weeks ago I was at the Communications Museum in Seattle, and they had a Command Set just like yours, tuned to the Boeing Tower frequency. The British broadcaster is turning to frequencies that still work during a communications blackout. If only more kit of that vintage was restored and demonstrated, then some of the static aircraft exhibits would at least sound like they were still usable. I made a lot of contacts on it. . Tripod mast or 11 m mast. Aviation Distress (VHF Guard) 118.000 - 121.950 MHz. Depends on the service. By 1940, the Naval communication system included technology capable of high, medium, and low frequencies that could send signals out to all corners of the globe (U.S. Dept. If a capacitor failed, then it must be re-stuffed. 69 0 obj 65 0 obj This unit switches-on every time without fail, whrring away for innumerable demos for friends and family. I found that all but three of the metal-can-sealed wax and paper caps (special to ARC-5 and other WW2 radio equipment, otherwise known as flower pot capacitors due to the shape of their metal cans) and the electrolytic caps needed to be replaced. Mast or tower. Fug 19: A transceiver operating in the range 3 - 7.5 Mhz. Operating on the 1250 - 1390MHz band, two channels. Within the VHF aviation communication frequency range, the most commonly used frequencies and their corresponding allocations include: Frequency. The original contractors were Turner Construction Company of New York, the Raymond Pile Company of New York, and the Hawaiian Dredging Company. It wont be factory original but will represent the era. Very nice restoration! Newer computer modeling is also used. The Hellcat was of course better but that is only to be expected. Very impressive! This office would be responsible for coordinating all of the purchasing and shipping of supplies (Woodbury, 1946:68). Just curious. Naturally their foray into military-technology innovation affects the way defense satellites are designed in the next half-century. The Paraset was a small, low-power, thermionic valve CW morse code-only radio transmitter-receiver supplied to the resistance groups in France, Belgium and the Netherlands during World War II. Yeah, I try to scan whatever manuals I can but I have yet to figure out how to scan the manual for my old military generator since it is bound. Nice! An early application of electromagnetics is on radio detection and ranging known as radar, which is an interdisciplinary subject involving communications, signal processing, and propagation. the vital issue of using private contractors to do the work in the pacific. Generally speaking much lower than common use bands today. Derp, sorry only trawled the top layer of the grey matter there, been reading some vintage computer pages where they (mis)use reforming to mean blowing out the shorts, forgot the older process. endobj It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 30 Watts. To check each cap I had to remove each of them from circuit, one at a time. Press question mark to learn the rest of the keyboard shortcuts. BETWEEN WW1 AND WW2 After the WW1 scientists continued researching of underwater radio communication. Press J to jump to the feed. In comparison, there's a morning Ohio rag chew net that operates on 28.337 MHz, Monday-Friday at 8:30 am. 8 0 obj endobj In modern low-voltage electronics the key metric to capacitor goodness is ESR. 84 0 obj The Submarine Base at Pearl Harbor, established in 1919, found itself at the forefront of war operations for the Pacific during World War II. Fortunately, it is easy to find documentation for WW2 radio gear because it was ubiquitous in the late 40s through the early 70s in amateur radio stations across the world (here is a PDF link to the manual for all or most ARC-5 gear). A system was needed that could send messages to the bottom of Tokyo harbor. The GEE MkII was the main navigation system used throughout WW2 in Europe. Was present in almost all German tanks and some other vehicles. << /S /GoTo /D (subsubsection.2.2.1) >> I think its output is 3k. Macona: Low as 50v on the plates but diminished audio . Radio. They used radio frequencies from 15 kHz to 33,3 kHz. Number ranges were not unique across the services so sometimes different equipment used by different services had the same FuG prefix. Instead of replacing the caps I opted to do a cursory check of the caps and try powering the unit up for an assessment. Known for being one of the first hand-held models, over 130,000 SCR-536 units were used to help conduct many important missions, including the famous invasion of Omaha Beach in Normandy. Otherwise, you should probably ask around in the area in which you plan to operate. Sadly the impact of this (significantly improved Command and Control of forces at the tactical level) gets virtually no 'airtime'. She told me that during WW2 they were encouraged to listen to the common German frequencies, apparently they could usually hear the tank divisions pretty well. Power 220 V AC 50Hz. FuG 6: A high-band HF/low-band VHF transceiver. (Air Drops) Pomeroy and Company, Inc. On July 11th, 1940, a new bill was approved (Woodbury, 1946:140). Transmitters utilize a MOPA (Master Oscillator Power Amplifier) architecture supporting AM phone and CW (aka Morse code) transmission. Im totally on your side generally; but its really not a crime to play around with gear like that and drill some holes. It was usually installed in section leader and company commanders' vehicles, to allow them to listen on one frequency while transmitting and receiving on another. Anthony Rabine has added a new log for OpenStoryTeller. I found a video on servicing a similar motorand proceeded to strip mine down, clean out the old grease in the bearings, put new grease into the bearings, clean the armatures, and re-assemble. This class of equipment includes separate transmitters and receivers that can be controlled remotely by the pilots through a remote control head mounted somewhere in the flight deck. Theres no getting around this, otherwise you might miss-read the cap value or leakage test. This radio transmitter was 25 watts and had a range of 7 miles moving, and 10 to 15 while stopped. Torn.Fu.c: A HF transceiver. If a capacitor failed, then it must be re-stuffed. In some command units. VHF frequency is widely used in analog TV broadcasting since it started a few decades back. With this increase in appropriations the Contractors also needed to expand their resources and invited in two new private companies, the Morrison Knudsen Company, Inc. and the J.H. Used by the infantry at the regimental and battalion level. Radar beacons to identify the aircraft as a friendly (identify friend or foe, or IFF). Range up to 100km. But if you have an old frequency generator also marked in cps, One more item was needed to give the Pacific fleet full striking power: absolute certain means of radio communications with headquarters at Pearl. It drives me nuts to see someone take something that should be in a museum and butcher it. I also got a lot of use of the BC-453 low frequency version as an improvement to my Hallicrafters receiver connecting it to the 455 Kc IF to take advantage of the low IF (85 Kc) to give improved selectivity. KL.Fuspr.d: A VHF transceiver. All caps were open-circuit as far as my DVM was concerned (unfortunately DVMs are not sensitive enough for a proper leakage test, more on this later). With good resistors, good caps, a working dynamotor I then moved onto the tuning mechanism. The station was highly experimental and also highly classified. FuG 7: A VHF transceiver (receiver/transmitter) used in command tanks. I have a Book Scanner that can do bound books. << /S /GoTo /D (subsection.4.1) >> endobj It was at this point that I shut it down, this radio wanted to work and all I had to do now was clean her up and fix a few things. Copyright 2022 Friends of Ha'ik Stairs. After much deliberation and intensive screening three companies were determined to be the strongest competitors having knowledge, experience, and imagination. Single-unit "walkie-talkie" system. I measured <1 uV on AM at 2 MHz, more than good enough for me and easily exceeding the original factory spec. During the war this was extended to cover the majority of the occupied areas or Europe and North Africa. Octal tubes were used as the active devices and the operational frequencies did not exceed 20 MHz, which was considered a high frequency for the mid 1930's. This radio gear was light-weight for WW2. Range 1.5km. FM stations operating in the old frequency band were required to move to the higher frequencies and most did so before 1948. Crystals for daytime were the higher frequency ones. M. Bindhammer has updated the log for Enhancer mask. Learn how your comment data is processed. SCR-536 This device was used by the U.S. Army during World War II. FuG 11: A medium-wave transceiver (receiver/transmitter) used in command tanks. I think its laudable that he kept the mods and replacements to a minimum. 4 LiamCH91 2 yr. ago Channel 2 8000 CPS teletype. stream FuSpr.f: A mid-band HF transceiver. It operated in the 4247.8MHz range. The Shortwave Broadcast Bands During WW2 I've always been curious about what the short wave bands sounded like in the United States during World War II. It was used with a frame antenna on various reconnaissance units. John in Texas. 48 0 obj Next I had to locate documentation. If one fails and the failure results in burning up some much harder to replace part was it worth it? Old radios are like old cars, they could use an alignment from time to time. I hooked up my 20m dipole and to my amazement I was tuning in AM broadcast stations at around 1500 Kc. However, The radios would probably be near identical to CBs in their function, key differences being Freq Range, power- ect. Nice work on the restoration. Channel 2 8000 CPS teletype. With the strong powered radio signals they succeeded to communicate from a distance of 16 nautical miles, depth of submarine's antenna was 10 metres. At this point in time the proposal for the Pacific Naval Air Bases was being limited to defensive measures. .15 Watt output AM voice and CW. USING THE RADIO ON MAIN STREET. 73 Mike AA9IL. Now there are so many easily modifiable kits and open source designs the remaining historical items are better off as museum pieces. (BBC Signal and Sunspots) Given the changes to the tuning unit I realized that I had to do a full alignment. Aircraft used a variety of frequencies. 1.5 Watt output AM voice and CW. Actually, the 3D printing would solve a nasty problem in making WW2 gear operate again; finding the connectors! 53 0 obj This equipment provided for 125 radio channels at 50kHz channel spacing. In the 1920's and 1930's the Russians developed a number of radio-controlled systems. ESR is Equivalent Series Resistance and NOT Electrostatic Resistance as you said. Operating on the 600 - 650MHz band, two channels. 40 0 obj Occasionally the shorted Fu designation were used and there were exceptions to both these systems. No ham has ever laid a soldering iron or a drill bit to it. To preserve this historic treasure my rules of restoration were: These were not easy rules to follow because, as we know, the first step to antique radio restoration is to replace all of the paper and electrolytic capacitors, saving a lot of headache and time. endobj endobj Used by the infantry. (Sky-wave propagation) I found mine at the Dayton Hamvention many years ago for $10. Nice! It operated in the 2.5-3.5MHz frequency range. The Navy believed it possible to use the natural geography to create the necessary height. I listened to a basketball game from an AM broadcast station in Chicago, I tuned into WWV at 2.5 MHz, and tuned in an 80 m AM net. Join the movement, there are many others who restore WW2 and other vintage gear to be original as possible. The CBY-46104 covers 1.5-3 Mc either AM or CW (it can also tune in SSB in CW mode), made by the Aircraft Radio Corporation of Boonton N.J. in February 1942 with SN# 1777. Fug 20: A 0.1 - 7.1MHz receiver paired with a 1.1 - 3MHz transmitter. The station would be able to obtain long range signals because it would use a very low frequency. In 1920 a receiver station was constructed at Wailupe. 57 0 obj It operated in the 4.5-6.67MHz frequency range. The men that reached the ridgeline were pondering the possibilities and problems of construction at the site. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 80 Watts. It operated in the 1.87 - 3MHz frequency range. Your painstaking dedication to detail and historical accuracy means that the next caretaker of this radio will still have plenty of historical context surrounding each of the individual parts, construction, etc. 3. 37 0 obj Stephen Chasey liked LIDL PARKSIDE Battery hacks. Another system, and the subject of this blog piece, was the F-10 radio-controlled mine. Long range transmissions were done in Morse code to keep the radios as simple as possible and to maximize their effective transmission range; a series of beeps is much easier to understand than voice. It was used on most of the larger aircraft in the war. Receiver probes are inserted from a room underneath the model while test signals are transmitted from the gantry. From this information shown on the navigators screen, a course to the target or as home run could be plotted. << /S /GoTo /D (section.3) >> I figured out the problem after about five minutes of reverse polarity operation. 41 0 obj 5 0 obj It was used for CAS operations, though these became rare after late 1944 with the result that many command tanks with this equipment fitted were converted to other roles. It operated in the 1.5-2.6MHz frequency range. Tower up to 50 m. Transmission power 3.5 watts. Walkie-talkies even inspired a major cell phone network. I followed the instructions from the original service manual, aligning the IF first (using a modern synthesized signal generator to get it spot-on), then the front-end variable cap assembly that I had just repaired. endobj I like old military shortwave radios. Power 220 V AC 50Hz 680 VA. Stuttgart - FuG D 3: Development item, possible none deployed. endobj A compromise has to be made you can either leave a radio totally original, OR you can have it working to its original specification. It was matched with the Luftwaffe transceiver Fug 17 in ground support operations. When we were young; in the 70s; we destroyed literally tons of stuff like that just for fun. The communication on these frequencies was by either hand keyed Morse code or radio teletype. That would be a good station to calibrate his dial on. Dynamotor worked perfectly, just like new again! 1, dated 15 January 1943: "The designation of Radio Intelligence in these regulations is a general term for attacks on the communications and operations of enemy communications. This site uses Akismet to reduce spam. As much as Ive read about Dynamotors, Ive never seen on in action. Logistics were quickly decided upon and offices began to function. The audio amp tube socket is a problem. 1. It is not easy hooking-up military surplus radios because they typically use multi-pin multi-use connectors for power and other controls. Michael 2 B - DMG 4a K: Truck-mounted. Axis Sally (Mildred Gillars) Several American Nazi sympathizers worked as broadcasters for German state radio, but perhaps none was as famous as Mildred Gillars. [2], Torn.Fu.g: A HF transceiver. %PDF-1.5 The ghostly radio station that no one claims to run - BBC . During World War II, the German Army relied on an diverse array of communications to maintain contact with its mobile forces and in particular with its armoured forces. No, X86 Single-Board Computer! Radio during WWI At the onset of World War I, radio was still in its infancy. This radio came in at 181 pounds. I did have a BC-348 at one time, when I was in college and that was my receiver for the station I took to school paired with a home made CW transmitter using a 6L6 on 80 and 40 meters. Section 2.104 provides information about the International Table while Section 2.105 contains information regarding the US Table of Frequency Allocations. Very cool! It needs some work too. Today the . It operated in the 42,000 to 48,300kHz (42-48.3MHz) frequency range with a transmission power of 20 Watts. 60 0 obj endobj Small world. It operated in the 23.11 to 24.01 MHz (24100 to 25000kHz) frequency range with a transmission power of 5 Watts. He had built a little one tube power supply to replace the dynamotor. As others have mentioned; MW & lower HF frequencies being the most used for medium to long range, with high HF/low VHF for short range. Old resistors tend to increase in value over time. 64 0 obj It also seems from recently received info that in 1947 the World Radio Conference and ICAO adopted the basis of current system(118-132Mhz later expanded to 136, then 137mhz) for en route/ local traffic/Approach/Tower etc..while HF was retained for long distance comms (much . As the submarines left the harbor and ventured into Japanese waters there was an exigency for communication (Allen, 1950: 225). https://www.youtube.com/channel/UCYQXlaLJRzzW9TYSynzOAvg. 44 0 obj FuG 13: A Fug 6 with two receivers rather than one. The Role of Radio in Wartime France. More information including downloadable manuals here; http://radionerds.com/index.php/SCR-522 Anne Member for 14 years 3 months Military radar band nomenclature, L, S, C, X, Ku, and K bands originated during World War II as a secret code so scientists and engineers could talk about frequencies without divulging them. It was used for by observation teams of the Sturmartillerie to communicate with artillery units. endobj MUF: Maximum Usable Frequency MW: Medium-wave SW: Short-wave VoACAP: Voice of America Coverage Analysis Program 4.2 Overview Radio propagation is the mechanism by which the EM waves (also known as radio waves) are transmitted, or propagated, from a point on the earth to another directly or through various layers of the atmosphere. DMG 3 K: Truck-mounted. Military radar band nomenclature is widely used today in radar . endobj Dynamotors are motor-generators; in my case one end is a spinning motor at 28VDC motor and the other end is a 250VDC generator. 1 Watt output AM voice and CW. R1155 frequency range: 75 kHz to 18.5 MHz depending on the model variant. Unfortunately, I did modify the chassis to accommodate some kind of tuning knob and vernier in an attempt to slow down the tuning rate for cw. A true restoration, not a replace old carcass with modern guts restoration like weve been so used to seeing. Operating on the 475 - 525MHz band, two channels. It operated in the 23,000 to 24,950kHz (23-24.95MHz) frequency range with a transmission power of 10 Watts. I re-connected it the correct way and it worked just as well as it did before. 1 0 obj A 1913 aircraft with a radio, at the time considered cutting-edge equipment, had a maximum range of 2,000 yards. (Critical frequency) 49 0 obj endobj Within seconds stations starting coming in strong, much louder than before. Power output: 40 to 70 watts on CW and 10 to 17.5 Watts on speech or MCW I even used the receiver as a tunable IF in a science fair project experimenting with mixers/converter for 10mhz WWV. Took first prize in my category! I can confirm 30ish mhz, as I used them in training. A technician who modifies or hacks a radio to transmit on frequencies beyond its usual design parameters. Long range radio systems to communicate back to base, typically consisting of an ART-13 transmitter and a BC-348 receiver. Ive become a believer in testing all the caps now. The later was tricky, with some high, medium, and low-band-specific alignments required. Torn.Fu.h: A HF transceiver. The chances of doing that without replacing any components is probably around 1% for radios of this vintage and I have done dozens of them over some 26 years.
