>> As an aside, this included radio-controlled tanks. The F4F is often underrated today because its performance numbers look so bad on paper but it had a very good kill ratio and it was the main US fighter at Midway. Next I checked all of the resistors with my Fluke DVM. Range up to 100km. 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. Radio: Long haul communication was primarily HF (High Frequency) radio 4,000 to 30,000 kHz giving ranges up to 3,000 or more miles. Consisting of an RFID reader and transponder, RFID systems can include multiple tags (antennae paired with a microchip) that can send out . Channel 2 6000 CPS teletype. (Multipath) 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. endobj I was a bit surprised at how the caps actually tested. I figured out the problem after about five minutes of reverse polarity operation. It operated in the 33.8-38MHz frequency range. More to the point, how might the workers themselves reach the top of the ridge (Wainwright, 1997). After the war the codes were declassified and Ka band and millimeter (mm) were added. 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 1930s. For B+ I went to the dollar store and bought 20 9v batteries and snapped them together into a B+ strip If one fails and the failure results in burning up some much harder to replace part was it worth it? It operated in the 3-5MHz frequency range. Channel 2 8000 CPS teletype. << /S /GoTo /D (subsection.5.2) >> It was usually used with a two-metre antenna. Over one hundred firms applied to be the Contractors used for the Pacific Naval Bases. 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. The GEE MkII was the main navigation system used throughout WW2 in Europe. Those old radios are fun. I removed the bells (end caps) from both sides of the motor. Radio during WWI At the onset of World War I, radio was still in its infancy. 29 0 obj SO glad that the seller didnt touch it and you kept it as stock as possible! Of course, they called them megacycles, rather than MHz. 73 Mike AA9IL. Free shipping for many products! Tripod mast or 11 m mast. Come on, there are a gazillion of those out there. For high voltage capacitors, the key metric of goodness is leakage. It wont be factory original but will represent the era. In other words, they were planning ahead for this conflict (an interesting book on this topic, how war production in the US was set up in advance by an executive from General Motors who established GMs global supply chain in the 20s and 30s). It is not easy hooking-up military surplus radios because they typically use multi-pin multi-use connectors for power and other controls. I tweaked the antenna coupling control, they were louder still. Next I had to locate documentation. Infantry. 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. How the lineage of the walkie-talkie reaches from World War II to the modern cell phone. 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). It was usually used with a two-metre antenna. 73, gary/NJ8BB. Frequencies around the 13-18 GHz band is where precipitation radars generally operate. It was running but not well. EDIT: forgot to add that nearly all transmitters employed crystal-oscillators (wartime demands actually drove research to make leaps in radio crystal quality). It operated in the 23-28MHz frequency range. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 30 Watts. It was usually used with a two-metre antenna. Now that everything was in order it was time to try the radio in its final configuration. More information including downloadable manuals here; http://radionerds.com/index.php/SCR-522 Anne Member for 14 years 3 months During night time contacts the lower frequency crystals should be used. This mine was first developed in 1929 (90 years ago!) It operated in the 4.5-6.67MHz frequency range. It could receive its output. I found mine at the Dayton Hamvention many years ago for $10. I did that once with a couple of books and used OCR software on the images to create a searchable PDF. He wanted to convey to the world the idea that Nazism was an acceptable political idea and his first radio broadcasts were performances by some of Germany's top orchestras and opera singers.Once this approach had bedded down, he introduced a system whereby little messages were broadcast piece by piece - spreading the . But now with what you have done, I will go thru the receiver completely. 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. endobj It operated in the 4247.8MHz range. One of the forerunners for this technology was the revolutionary electrical musical instrument developed by Leon Theremin. The result was an overseas radio facility program that was advanced in proportion and technology above other area installations. Sadly this is no longer the case. (BBC Messages) Otherwise, you should probably ask around in the area in which you plan to operate. I remember visiting a couple of friends (G4EYL and G8LUV) in the 80s, and they noticed some CBers on a ham band. endobj These things are built like tanks! Power battery. endobj If small amounts of current (on the order of single-digit uA) leak through then that capacitor is bad. B^), Great job! This unit switches-on every time without fail, whrring away for innumerable demos for friends and family. (Comment Policy). It operated in the 1,130 to 3,000kHz frequency range. 28 0 obj 73 0 obj As it operated on the same band as the FuG 5 it allowed them, for example, to listen to the regimental command net while talking to the subordinate units at the same time. Most places cant scan books without destroying the original unless you pay a fortune. Anyone have some cool facts to share? Also known a USW receiver c1. The communication on these frequencies was by either hand keyed Morse code or radio teletype. Could be used on the move with one man carrying the transmitter/receiver and the other the battery/power supply and handset. The radio could have been used in both. In Hawaii,Navy communications began in September, 1916, at Hospital Point, Pearl Harbor. When we were young; in the 70s; we destroyed literally tons of stuff like that just for fun. Radio Saigon was designated to carry anti-British broadcasts to India, backed up by similar programs emanating from transmitters in Singapore and Bangkok. 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. Of course, it had a dynamotor power supply, which we used to (only half jokingly) refer to as a rotating short. 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. Within the VHF aviation communication frequency range, the most commonly used frequencies and their corresponding allocations include: Frequency. 72 0 obj In the 1920's and 1930's the Russians developed a number of radio-controlled systems. endobj It needs some work too. It spun up like a 1950s jet engine! FuG 17: Designation for a Torn Fu H transceiver. One of them went under the stairs and there was the characteristic sound of a dynamotor spinning up they blasted out Morse at (I think they said) 2kW for a few seconds and then G4EYL used her best local-radio announcers voice to tell them they werent welcome. endobj [2], Torn.Fu.f: A HF transceiver. << /S /GoTo /D (subsubsection.2.2.2) >> Everything from receivers to transmitters that ran on low voltage DC busses used dynamotors to generate the 200-1000V, or more, needed for operation. noun. ahh jeez, that was meant at top level, idk how it ended up as a comment 3 levels down. To check for value and leakage with one test device you must resurrect an old piece of test gear known as the capacitor checker. I think you did a great restoration just a pity about nonsensical rules! It tuned the 40 meter ham band, and I spent many an evening with it. Number ranges were not unique across the services so sometimes different equipment used by different services had the same FuG prefix. 2.2. FuSpr.a: A mid-band HF transceiver. The museum ships often have fully operational radio rooms wherein folks make the old radio gear work again. Power 22 V AC 50Hz 300 VA. Rudolf - DMG 3 G: 'Heavy' link. Just curious. Fortunately these are easy to service, they are designed so that anyone with a flat-head screwdriver can fix them. Something was not right with it, the plates on the large variable tuning cap were literally grinding against each other. It was usually used with a two-metre antenna. These radios were designed in the mid 1930s. I used to have a transceiver built in the U.S. for use in Russian tanks, during WWII. endobj In 1931 land was bought in Lualualei Valley for the purpose of constructing a new transmitter facility. (Tactical Information \(non-coded\)) endobj 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. Testing capacitors with a DVM in resistance mode will show which are short-circuited but it will not reveal the leaking capacitors that are only leaking ever so slightly (e.g. Over the next three years the contracts given the CPNAB grew to be the largest contractual award in history. 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. That radio has an acceptance stencil from Alameda Naval Air Station Channel 2 8000 CPS teletype. It operated in the 24.1 to 25MHz (24100 to 25000kHz) frequency range with a transmission power of 5 Watts. The only exception for me is that historical books and papers should be preserve, so we can know what has preceded us. By 1943 Japan controlled about forty broadcasting stations and was able to have programmes going out on shortwave around the clock on more than fifty frequencies. In comparison, there's a morning Ohio rag chew net that operates on 28.337 MHz, Monday-Friday at 8:30 am. The G series were still mobile but were intended to form more of a backbone for communications and were intended to remain in place for longer periods than the K. They again used a series of masts up to 50 m high. Specialized Mobile Radio (SMR): Also see Enhanced Specialized Mobile Radio ( ESMR ). 17 0 obj So, I suppose in WWII it would have been Baker!) Its very rare that resistors are all in tolerance (as here), but it could happen (German resistors are excellent in this regard). It operated in the 23,000 to 24,950 kHz (23-24.95 MHz) frequency range with a transmission power of 10 Watts. Tower up to 50 m. Transmission power 0.4 Watts. I wish I still had it, but the car it was in was stolen from me, and when I got the car back, the radio was no longer in it. Nice work. Feldfu.a1: 120-156MHz infantry, a VHF transceiver. Allocation. 1 Watt output AM voice and CW. Section 2.104 provides information about the International Table while Section 2.105 contains information regarding the US Table of Frequency Allocations. I have a Book Scanner that can do bound books. FuG 2: A high-band HF/low-band VHF receiver. If I have to restuff a capacitor because its failed, in my book that means I am fitting a new component. B^). I can do 36-inch wide scans and prints from a plotter if needed. VHF frequency is widely used in analog TV broadcasting since it started a few decades back. Anyone, anywhere in the world can listen in, simply by tuning a radio to the frequency 4625 kHz. The wireless was invented by Marconi in the late nineteenth century and the Navy was quick to make use of the new technology. Range approximately 10km with Cw and 3km with voice. 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. Join the movement, there are many others who restore WW2 and other vintage gear to be original as possible. England. endobj endobj ( VoACAP's Parameters) It was first used in combat early in 1944 on the Anzio beachhead in Italy. The 1940s also came to be known as the Age of Golden Programming for radio shows. << /S /GoTo /D (subsection.2.1) >> The electrolyics, however, were extremely leaky and did not reform. It was used for by observation teams of the Sturmartillerie to communicate with artillery units. endobj The units of the T series were "backpack"-style mobile equipment. Range 2 km AM voice to 4 km CW. Those old caps still working is amazing, and a testament to just how terrible the knockoff electrolytic caps are. No, X86 Single-Board Computer! Torn.Fu.h: A HF transceiver. First Responders Interoperable Radio System Team (FIRST) Trunking System Profile. I just helped a friend get one working last week. This would be the first time that the Government had ever used this method on a big job (Woodbury, 1946: 52). From the documentation I figured out what had to plug into the multi-pin connector on the back; +28 VDC, an external CW/AM toggle switch, RF gain control pot, 600 ohm speaker (I used an 8 ohm speaker and impedance matching transformer). endobj I am familiar with these radios and have had a few of them in the past, but dont have any now. 30Mhz+ is used by the government to this day, along with other PMR Licensees. 16 0 obj FuG 13: A Fug 6 with two receivers rather than one. I opted to remove the dead electrolytics and keep the old parts in a little paper bag. Short-range radio systems designed for aircraft-to-aircraft communication, known as command sets subdivided into a multitude of bands. It is a measure of the effectiveness of a filter capacitor. I hooked up my 20m dipole and to my amazement I was tuning in AM broadcast stations at around 1500 Kc. endobj endobj (on the work youve done and the article) Power 220 V AC 50Hz. Used by anti-tank units. 65 0 obj There I found a unicorn of historical significance; an un-modified-since-WW2 surplus CBY-46104 receiver with dynamotor. We are now at a point where the surplus WW2 electronics should no longer be hacked to bits. photo right . << You might enjoy this video on reconditioning a WW2 aircraft radio that was converted to civilian use. << /S /GoTo /D (subsubsection.4.4.3) >> endobj I kept the flower pots to reverse the mod. 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. Given the changes to the tuning unit I realized that I had to do a full alignment. https://mapsairmuseum.org/what-constitutes-a-radio-on-a-wwii-era-bomber/#:~:text=The%20predominate%20command%20installation%20during,5%20command%20series%20was%20used.

By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 21 0 obj A technician who modifies or hacks a radio to transmit on frequencies beyond its usual design parameters. What an incredible receiver, it was wide awake and operating to its original specifications once more! 77 0 obj In January of 1939 the Naval Affairs Committee opened hearings on the specifics of the proposed new Naval Bases. 45 0 obj I know ATA ferry pilots had no radio, even on repaired planes, and was wondering how that was accomplished. Today surplus stores only have contemporary Chinese-made boots, camping gear, and flashlights. At the time it was considered one of the largest radio receivers in the world and could receive six messages simultaneously. It was used with a two-metre antenna. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 80 Watts. 8 0 obj Pomeroy and Company, Inc. On July 11th, 1940, a new bill was approved (Woodbury, 1946:140). On August 9th the contract (No y-3550) was approved and the Contractors began work. Anthony Rabine has added a new log for OpenStoryTeller. The K series were truck mobile units using a range of masts up to approximately 11 m tall. endobj Now *that* is how you do a restoration! It could be powered by 12 or 24v dynamotors. Electromagnetic radiation falls . 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. Miraculously it came to life when powered. 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. stream It operated in the 23,000 to 24,950kHz (23-24.95MHz) frequency range. I think its output is 3k. 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. Shorter range communication was on 500 kHz almost entirely hand keyed Morse with a range of up to 500 miles. My elmer was a B17 radio op. Spaceborne altimeters generally use frequencies in the 2-18 GHz band while scatterometers generally use frequencies between 5-36 GHz.

Transmission power 3.5 watts. 68 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. A capacitor must operate to its specified value so it is good to test to see if the cap is functioning as a cap. SCR-536 This device was used by the U.S. Army during World War II. << /S /GoTo /D (section.5) >> This innovation constituted the Contractors, Pacific Naval Air Base (CPNAB). Copyright 2022 Friends of Ha'ik Stairs. I wonder if the Nazi's used Hertz? Usually they used 30.xx MHz area frequencies (low band, radios close to 10 meters) AM mode usually. (Hops \046 Skip Zones) Army equipment was primitive, had a very short range, and often negotiated atmospheric interference. Radio frequency radiation is a type of electromagnetic radiation, which is a combination of electric and magnetic fields that move through space together as waves. DMG 2 T: Pack unit, operating on the 475 - 525MHz band, single channel voice or 800 character-per-second teletype. It was matched with the Luftwaffe transceiver Fug 17 in ground support operations. Electronic warfare receivers to detect enemy radar signals. It is probably more authentic after a good re-capping and re-alignment. Ground-to-air range 60km AM voice to 80km CW. The parasets the British SOE sent to operatives in occupied Europe used low HF, 3-7 MHz. 81 0 obj I was one of the youngsters who got an ARC-5 receiver in the mid 50s. So my unit has some historical meaning and context. Most times a good proportion of resistors have to be replaced..with modern parts, because if you find old parts of the same type they are all out of tolerance too. The receiver was not too sensitive, and tuning was jammed up at the higher frequency ranges on the dial. With the receiver aligned I tested its sensitivity. They used radio frequencies from 15 kHz to 33,3 kHz. When they did not have enough time to gain altitude they had catastrophic losses. Besides if you really want the original experience.. it didnt have 70 year old caps in it 70 years ago! Operating on the 1250 - 1390MHz band, two channels. Usually they used 30.xx MHz area frequencies (low band, radios close to 10 meters) AM mode usually. << /S /GoTo /D (subsection.6.1) >> The wireless was invented by Marconi in the late nineteenth century and the Navy was quick to make use of the new technology.

The BC-604 has a drawer with room for all the crystals for its 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. The men that reached the ridgeline were pondering the possibilities and problems of construction at the site. Dynamotors are motor-generators; in my case one end is a spinning motor at 28VDC motor and the other end is a 250VDC generator. At this point I had two toggle switches and a pot with a mess of wire shoved into the rear panel connector pins. One more item was needed to give the Pacific fleet full striking power: absolute certain means of radio communications with headquarters at Pearl. Its just too bad that theres not as much to listen to in HF these days, unless one jumps into amateur radio. In particular they questioned how the wires would be brought to the top of the ridge from the Valley side. Michael 2 B - DMG 4a K: Truck-mounted. Both the army and the air force made use of the same equipment. In 1936 the Lualualei Valley transmitter was activated (HABS, 1997:6). (Tactical Information) I have a 7mhz version of this receiver (black navy) that I used in my novice days in 1976. 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. 88 0 obj Feldfu h: 23.1 - 28.0MHz Assault Guns and Sturmartillerie. Navy, 1946:139). Air to ground radio communication equipment. Later a simplified version (b2), of lower power (.12w), was used by the Panzergrenadiers.[3]. Torn.Fu.b: A HF transceiver. This thing was preserved as good as the day it was removed from its F4F Hellcat. endobj One minor nitpick from the writeup F4F refers to a Wildcat, whereas a Hellcat uses the F6F designator. ( Critical frequency, LUF/MUF, Hops e Multipath) I think its laudable that he kept the mods and replacements to a minimum. It is a criminal offensive to hike the Stairs, and you could be fined a minimum of $1000 if you are caught. Receivers use a single-conversion heterodyne architecture similar to that of big wood console radios of the era. 2 Watt output AM voice and CW. I opted to re-stuff the defective caps by opening the metal cans, extracting the guts, and putting in a modern replacement, then gluing the cans back together. Found this today, while researching how to fix up my CCT-46192 (roughly like the AN/ARC-5 R23) that hasnt seen power since probably 1985. 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. As much as Ive read about Dynamotors, Ive never seen on in action. 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. Which Gen Set Manual do you have? It was used by armoured observation posts. Olek has updated the project titled Fan Controller. No replacement of any components whatsoever. Yes, the rolled paper/wax seem to hold up forever unless electrically or physically abused. Born in Maine, Gillars was a. It operated in the 23,000 to 24,950kHz (23-24.95MHz) frequency range with a transmission power of 10 Watts. Big dynamotors explode in total awesomeness if you apply mains voltage to them. Single-unit "walkie-talkie" system. 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). How the Nazi army communicated wirelessly, Wireless Communications of the German Army in World War II, "Technical Manual: Handbook on German Military Forces", "Summary of Characteristics of German Decimetre Communications Equipments", https://www.dropbox.com/s/ht7s2xjb8vovnbn/article-German-Communication-UHF-DMGmichael.pdf?dl=0, https://en.wikipedia.org/w/index.php?title=Wireless_Communications_of_the_German_Army_in_World_War_II&oldid=1077340533, All Wikipedia articles written in American English, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 15 March 2022, at 20:35.
