radio frequencies used in ww2

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. FuG 5: A high-band HF/low-band VHF transceiver. Long range radio systems to communicate back to base, typically consisting of an ART-13 transmitter and a BC-348 receiver. << /S /GoTo /D (subsubsection.4.4.3) >> Thereafter version b1 was used by the Pioneers. endobj Im surprised. It was used for by observation teams of the Sturmartillerie to communicate with artillery units. (Multipath) The communication on these frequencies was by either hand keyed Morse code or radio teletype. When the contract was finally terminated, December 31, 1943, the total construction and cost amount of their contracts was over $692,000,000 (U.S. Dept. This radio transmitter was 25 watts and had a range of 7 miles moving, and 10 to 15 while stopped. The time station is WWV on 2.5 MHz exactly. Matching the transmitters that operated in this frequency range, this receiver provided for 50kHz channel steps in the 27.0 to 33.3MHz range for a total of 125 available channels. I made a lot of contacts on it. The Navy would choose the contractors it believed competent to do pioneering work under stress of emergency, then pay them on a cost-plus-fixed fee basis. Ideally, capacitors should present no resistance whatsoever, but practical capacitors do present some low resistance and bad capacitors present a lot more than some resistance. The ghostly radio station that no one claims to run - BBC . 44 0 obj Besides if you really want the original experience.. it didnt have 70 year old caps in it 70 years ago! With such a receiver the young ham would be able to tune in radio traffic from all over the world and practice listening to Morse code (CW) transmissions. From 1936 the German forces started deploying a range of communication links using UHF frequencies to form a point-to-point mesh communication network. To check each cap I had to remove each of them from circuit, one at a time.

I can confirm 30ish mhz, as I used them in training. endobj It is a criminal offensive to hike the Stairs, and you could be fined a minimum of $1000 if you are caught. I figured out the problem after about five minutes of reverse polarity operation. Those old caps still working is amazing, and a testament to just how terrible the knockoff electrolytic caps are. a.m. at frequencies within the 1-10 MHz range . (Tactical Information \(non-coded\)) (Very Low Frequency band, VLF). Fug 21: A 0.1 - 10MHz receiver paired with a 2.5 - 7.5MHz transmitter. During World War II, the radio became a tool of immense political power. << /S /GoTo /D (section.6) >> The Navy believed it possible to use the natural geography to create the necessary height. Formed the base design of other units. Channel 2 8000 CPS teletype. 0.7 Watt output AM voice and CW. << When we were young; in the 70s; we destroyed literally tons of stuff like that just for fun. It was usually used with a two-metre antenna. The ART-13 is one of the most popular WW2 high frequency radio . On May 25th, 1939 Congress passed an appropriation bill providing 63 million dollars for Naval Air Bases. Replacement for Torn.Fu.f. Erythrocyte Sedimentation Rate. 4 LiamCH91 2 yr. ago The basic wireless invention went through a rapid evolution between the first and second World Wars. FuSpr.d: A mid-band HF transceiver. 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. FuSpr.a: A mid-band HF transceiver. Mr Carlsons Lab has a great video on how to use one. There is something I dont get though: I found that all but three of the metal-can-sealed wax and paper caps () and the electrolytic caps needed to be replaced. >> Radio helped entertain and inform the population, encouraging citizens to join in the war effort. Nice! I dont think you kept your own rules here because you replaced some capacitor with new parts. 28 secup 2 yr. ago I can confirm 30ish mhz, as I used them in "training" 16 NeuroG 2 yr. ago Of course, they called them megacycles, rather than MHz. It was first used in combat early in 1944 on the Anzio beachhead in Italy. ( Critical frequency, LUF/MUF, Hops e Multipath) Very cool job! The wireless was invented by Marconi in the late nineteenth century and the Navy was quick to make use of the new technology. 0.7 Watt output AM voice and CW. I left the original rear power plug in place and found out that miniature banana plugs fit perfectly into the WW2 socketed pins. Most of the community orbits around Electric Radio Magazine. Shorter range communication was on 500 kHz almost entirely hand keyed Morse with a range of up to 500 miles. Operating on the 600 - 650MHz band, two channels. FuSpr.f: A mid-band HF transceiver. Its definitely going the extra mile to do this and if you can keep it going a little longer than 20 years that will make it a hundred years old and possibly the future generations will see it as value and keep the restoration going. 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. Second, the contracts were awarded to large firms because small ones did not have the experience or talent for this large scale operation. I think its output is 3k. Just one thing about caps: ESR is not Electrostatic Resistance, its the Equivalent Series Resistance, Excellent posting and thanks for the dynamotor rebuild info. At one time (1976) I had it mounted in my 65 Datsun (named Ziggy), and used to work CW on 40 meters with headphones on and a key strapped to my leg. DMG 3 K: Truck-mounted. magopeter liked Flipper Zero Multi-tool Device for Hackers. It was used with antenna of either 1.4 to 2.0 metres antenna.

Radio during WWI At the onset of World War I, radio was still in its infancy. ahh jeez, that was meant at top level, idk how it ended up as a comment 3 levels down. 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. The major difference between German Army tank sets and US Army tank sets was the American use of FM for the high-HF/low-VHF bands. 64 0 obj The British broadcaster is turning to frequencies that still work during a communications blackout. This is a testament to not replacing all the caps if you dont have to. Range up to 50km. WWII Before the dawn of the Second World War, radio has become a common means of entertainment and information. The SCR-536 was a two-way, portable radio used extensively by United States armed forces during World War II. Short-range radio systems designed for aircraft-to-aircraft communication, known as command sets subdivided into a multitude of bands. Otherwise identical to Torn.Fu.b. Im totally on your side generally; but its really not a crime to play around with gear like that and drill some holes. 73, gary/NJ8BB. FuG 6: A high-band HF/low-band VHF transceiver. It was deemed that the 600 foot tower at Lualualei was not powerful enough to send radio waves of the length necessary for communication in the Pacific. I bought it from a fellow in a wheel chair who had a shed full of surplus electronics. .15 Watt-output AM voice and CW. Actually, the 3D printing would solve a nasty problem in making WW2 gear operate again; finding the connectors! Tripod mast or 11 m mast. endobj 30Mhz+ is used by the government to this day, along with other PMR Licensees. People were very hesitant to become involved in another war, particularly if America was not directly involved. Air Traffic Control (Towers and ARTCC's) 121.3 MHz. Power battery. Repackaged as FuG 3 neu for use with motorcycle troops. This equipment provided for 125 radio channels at 50kHz channel spacing. In Hawaii,Navy communications began in September, 1916, at Hospital Point, Pearl Harbor. No holes can be drilled, either on the chassis or on the plug-in. Repackaged for use in several other receivers and transceivers. Additional information about the FCC's table of frequency allocation is available in the Commission's rules. . << /S /GoTo /D (subsubsection.2.2.1) >> .15 Watt output AM voice and CW. I love seeing the WWII equipment properly restored. It tuned the 40 meter ham band, and I spent many an evening with it. 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. Later a simplified version (b2), of lower power (.12w), was used by the Panzergrenadiers.[3]. I can do 36-inch wide scans and prints from a plotter if needed. 17 0 obj There would be no bidding on the island contracts. Another system, and the subject of this blog piece, was the F-10 radio-controlled mine. Naturally their foray into military-technology innovation affects the way defense satellites are designed in the next half-century. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 100 Watts. I used these banana plugs to connect up the control panel and a 600 ohms speaker. 84 0 obj I was a bit surprised at how the caps actually tested. Olek has updated the project titled Fan Controller. Feldfu b2: Panzergrenadier only two tubes, no AF tube Rv2,4P700. If a capacitor failed, then it must be re-stuffed. Nicely done. << /S /GoTo /D (section.3) >> It was usually used with a two-metre antenna. Fortunately for me, and unlike solid state equipment, no damage was done. A cable linked the two men together. Early in 1945, in the Northern Appenine mountains of Italy, T/5 Harvey, a radioman with the 10th Mountain Division, is carrying his WW2 . It was matched with the Luftwaffe transceiver Fug 17 in ground support operations. 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. FuG 15: A HF receiver. It was used on most of the larger aircraft in the war. Particularly the higher valued ones in the 100s of K or M ohm range. That radio has an acceptance stencil from Alameda Naval Air Station Ive been told all my life about old-timey Army/Navy surplus stores where you could buy buckets of FT-243 crystals, radio gear, gas masks, and even a Jeep boxed-up in a big wooden crate. Could be used on the move with one man carrying the transmitter/receiver and the other the battery/power supply and handset. There I found a unicorn of historical significance; an un-modified-since-WW2 surplus CBY-46104 receiver with dynamotor. If run out of trim, I might do a little naughty and just strap a little booster cap across it. For example, according to the ARRL Ham net's directory, there's a Bartlesville, Oklahoma rag chew net that operates on 444.775 MHz on Wednesdays at 8:30 pm. Could interwork with the Fug 5 of the armour. In the hearings of 1939 were stated several points that convinced skeptics of the decision to use this system of CPNAB. Very nice rebuild, a lot of patience to test each capacitor multiple ways. So, I suppose in WWII it would have been Baker!) Remarkably enough, the vast majority of these Feb 1942 capacitors tested good. This radio gear was light-weight for WW2 standards, the CBY-46104 weighs only 6 lbs and is made entirely from aluminum. Next I had to locate documentation. Near exclusively AM mode. 56 0 obj Lets see how I did. How to make this low frequency radio system become reality was one of the most complicated jobs in the Pacific during the war. I was one of the youngsters who got an ARC-5 receiver in the mid 50s. 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. Range up to 50km. 65 0 obj . Isnt ESR short for Equivalent Series Resistance? Torn.Fu.d2: A VHF transceiver. USING THE RADIO ON MAIN STREET. FuG 16: A HF transceiver (receiver/transmitter) used in the command vehicles of Sturmartillerie units. 1 Watt output AM voice and CW. L.I.N.Y. High voltage was generated from the Dynamotor. Rather than having two motors with two shafts tied together (larger units on ships actually used such configurations) this motor is built into one compact unit with two armatures and two sets of brushes. Ground. The Admiral proposed: . Original vintage : 1941 Primary mains power: 12 or 24 VDC Variants :R1155A, B, C, D, E, F, L, M, and N.

My grandmother was a ham during WW2, my grandfather was in the signal corps. Everything from receivers to transmitters that ran on low voltage DC busses used dynamotors to generate the 200-1000V, or more, needed for operation. 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. I have been binge watching WWII movies lately and it got me wondering about what kind of radio frequencies where they broadcasting on back then. My unconventional restoration of this radio followed strict rules so as to minimize the evidence of repair both inside and out yet make this radio perform again as though it came fresh off the assembly line. This would be the first time that the Government had ever used this method on a big job (Woodbury, 1946: 52). 12 0 obj Later, I built some crystal controlled converters and use the BC-453 as a tuneable IF. 4 0 obj (Introduction) Sound torture is nothing new. Usually they used 30.xx MHz area frequencies (low band, radios close to 10 meters) AM mode usually. The initial problem was how to build a tower higher than 600 feet. All receiver dials, prior to WWII, were vague in accuracy and didn't provide . The Navy quickly decided to build a long range low frequency radio station in Hawaii using this type of natural resource. 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 . The station was commissioned on December 21, 1941, and grew to be one of the largest Naval radio stations in the world at that time (Allen, 1950: 226). Through the use of coastal spotters, advanced radar and early warning, they were able to gain an advantage by gaining altitude and make high speed diving attacks shooting in a high pass. Low as 50v on the plates but diminished audio I used to be all about modding things to unrecognizability but that was when new gear was so much more expensive. Radios in 1942 were large, power hungry, and expensive. Operating on the 1250 - 1390MHz band, two channels. FM stations operating in the old frequency band were required to move to the higher frequencies and most did so before 1948. This article is a list and a description of the radio equipment. FuG 9: A transceiver, operated in the 0.1 - 7.1MHz (100kHz - 7100kHz) range. Big dynamotors explode in total awesomeness if you apply mains voltage to them. 1940-1949 IT'S THE OLD STORY: A glamorous movie actress and a brash avant-garde composer get together to invent and patent a device that controls torpedoes by radio. Then noise came out of the speaker. Free shipping for many products! By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. The Aztec "Death Whistle" served a variety of purposes from human sacrifice rituals to warfare. Excellent project. 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). and deployed operationally in 1941 in the "Great Patriotic . It was running but not well. It was used with antenna of either 1.4 to 2.0 metres antenna. The FuG 2 was never used on its own but as an additional receiver in command tanks and relay devices.

The instrument could be . I then moved onto cleaning the Dynamotor. ( Voice of America Coverage Analysis Program \(VoACAP\)) The only exception for me is that historical books and papers should be preserve, so we can know what has preceded us. It operated in the 4.5-6.67MHz frequency range. 2.2. 0.6 Watt output AM voice. endobj I opted to remove the dead electrolytics and keep the old parts in a little paper bag. For general aviation, 122.75 is the official fixed wing air-to-air frequency designated by the FCC and FAA (and 123.025 is for helicopters). A system was needed that could send messages to the bottom of Tokyo harbor. Its just too bad that theres not as much to listen to in HF these days, unless one jumps into amateur radio. endobj stream Sadly, it disappeared in one of my folks moves. The Role of Radio in Wartime France. John in Texas. Workers hiked up the back side of the cliffs, from the Red Hill side, soon after the attack on Pearl Harbor. 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. Short wave was available on many, but by no means all, pre-war consumer radios. endobj By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies. Very, very well done! But now with what you have done, I will go thru the receiver completely. First Responders Interoperable Radio System Team (FIRST) Trunking System Profile . << /S /GoTo /D (subsection.4.4) >> Its very rare that resistors are all in tolerance (as here), but it could happen (German resistors are excellent in this regard). It was usually used with a 1.4 metre antenna. All paper/wax capacitors were fine. For this radio not one resistor was out of tolerance! B^), Great job! endobj U.S. amateur radio frequency bands and short comments about the frequency allocation models are presented in Picture 1. Channel 1 control channel voice, Channel 2 nine voice channels or p x 3 Teletype. It was used by armoured observation posts. 21 0 obj This office would be responsible for coordinating all of the purchasing and shipping of supplies (Woodbury, 1946:68). Nice work. A true restoration, not a replace old carcass with modern guts restoration like weve been so used to seeing. FuG 10: A medium-wave transceiver (receiver/transmitter) used in command tanks. EDIT: forgot to add that nearly all transmitters employed crystal-oscillators (wartime demands actually drove research to make leaps in radio crystal quality). Reconnaissance units later in the war. One of the first tasks was building the Operation Office in Alameda. It was usually used with a two-metre antenna. Today we use Mega Hertz which are totally incompatible.. just kidding. Some command and reconnaissance units had this infantry transceiver to allow then to talk to Panzergrenadier units.[2]. There were different systems for each specialized task: Somewhere in this menagerie of radio systems, you would find a CBY-46104 receiver. It had the rare 12 Volt dynamotor so I could use it as part of a mobile setup in the car. End of problem. ( VoACAP's Parameters) Looking back at my own history, its clear that the kids toys were always the last priority in a move. It was usually used with a two-metre antenna. Nice work on the restoration. In 1920 a receiver station was constructed at Wailupe. 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. How much current leaks through an old capacitor? 37 0 obj 41 0 obj FuG 17: Designation for a Torn Fu H transceiver.

Fortunately these are easy to service, they are designed so that anyone with a flat-head screwdriver can fix them. ( Introduction) 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. But a question: why go to all of the work to restuff caps and things, all hidden deep inside, but then have all that modern bright plastic wire, tie-wraps, psychedelic banana plugs and a modern speak hanging on the outside, its kind of trashing it up, like someone painting graffiti on it? Range 5km AM voice.[1]. (Fug 8 + Fug 4). It is a measure of the effectiveness of a filter capacitor. On August 9th the contract (No y-3550) was approved and the Contractors began work. If a capacitor failed, then it must be re-stuffed. But American pilots still avoided dog fighting and utilized the dominant characteristics of the Hellcat to inflict heavy losses. Along with the previously erected Naval station at Lualualei Valley was a naval communications station at Wahiawa, near Schofield Barracks. It operated in the 1.87 - 3MHz frequency range. The model is 1/48 scale and the frequencies used are 48 times higher than actual. The whrrrr was smoother than ever.
