( Introduction) Radios in 1942 were large, power hungry, and expensive. FuG 3: A low-band VHF receiver. (BBC Medium Wave and Short Wave Broadcasting) By accident I even connected the DC input backwards, reverse polarity. Torn.Fu.c: A HF transceiver. 2. (Air Drops) 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 . Formed the base design of other units. endobj Fug 18: Group of radios covering 25 - 77.1 Mhz Fug 19: A transceiver operating in the range 3 - 7.5 Mhz. Within seconds stations starting coming in strong, much louder than before. Whrrrrrrrrrrr.. After about 30 seconds the Whrrr sounded slightly bogged down, loaded down actually, by the vacuum tubes warming up and drawing current from the 250VDC output of the dynamotor. In the hearings of 1939 were stated several points that convinced skeptics of the decision to use this system of CPNAB. 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). It takes a lot I tested the electrolytic and paper caps with a Fluke DVM in resistance mode for obvious shorts or low impedance. Spaceborne altimeters generally use frequencies in the 2-18 GHz band while scatterometers generally use frequencies between 5-36 GHz. Mast or tower. Some radios are pre-programmed to repeater channel frequencies, and some will need to be . It was usually used with a two-metre antenna. I did make one modification to it: I added a pot to dial in some positive feedback around 2 of the IF stages. endobj 30Mhz+ is used by the government to this day, along with other PMR Licensees. It operated in the 2.5-3.5MHz frequency range. Transmitter power 1 watt. In 1936 the Lualualei Valley transmitter was activated (HABS, 1997:6). << /S /GoTo /D (subsection.4.1) >> Most of this equipment received the generic prefix FuG for Funkgert, meaning "radio device". have extremely high DC impedance) at high voltages. It was used by the observers to communicate with the armoured unit leaders via their Fug 5 radios. Everyone is thrilled and amazed to see a dynamotor-powered receiver that is running almost entirely on its original parts and as it was originally built. 49 0 obj Range 1.5km. 81 0 obj endobj It was running but not well. 44 0 obj This mine was first developed in 1929 (90 years ago!) R1155 frequency range: 75 kHz to 18.5 MHz depending on the model variant. Radio Communications in World War II Naval radio communication played a vital role in World War II efforts and Hawaii's defensive installation. I tweaked the antenna coupling control, they were louder still. It was used on most of the larger aircraft in the war. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 100 Watts. .15 Watt output AM voice and CW. By the winter of 1940 Congress began to understand the full impact of the Pacific turmoil and approved a bill that included $31 million specifically for the Pacific island bases. stream These radios were designed in the mid 1930s. Power 220 V AC 50Hz 250 VA. Michael 2 R - DMG 5 K: Truck-mounted. A giant sending station must be built that would reach not only to the waters of Australia and the Indian Ocean but also to every Allied submarine-submerged-especially if she were on the bottom of Tokyo harbor (Woodbury, 1946:349). I used to be all about modding things to unrecognizability but that was when new gear was so much more expensive. Look . Today we use Mega Hertz which are totally incompatible.. just kidding. FuG 17: Designation for a Torn Fu H transceiver. qk|UbVE4k%3DsRaEAYsombT_FG46m,@0E/N7U. Great project! 68 0 obj One of the tags has Signal Corps U.S. Army , can e-mail me for phone #. With good resistors, good caps, a working dynamotor I then moved onto the tuning mechanism. 41 0 obj I like old military shortwave radios. It operated in the 23,000 to 24,950kHz (23-24.95MHz) frequency range with a transmission power of 10 Watts. .5 Watt output AM voice and CW. 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. 4 0 obj It operated in the 4.5-6.67MHz frequency range. Working towards the same goal, they slowly and stubbornly inched towards a proposal for Pacific Naval Bases (Woodbury, 1946: 65). Axis Sally (Mildred Gillars) Several American Nazi sympathizers worked as broadcasters for German state radio, but perhaps none was as famous as Mildred Gillars. Laptop Motherboard? A cable linked the two men together. And of course lets not forget the legendary Collins ART-13 with auto-tune. I used to have a transceiver built in the U.S. for use in Russian tanks, during WWII. Frequency Meters provided a method of accurately measuring either a transmitted frequency or a received frequency of operating radio equipment. Comparable to the American SCR-508 tank radio, which covered a similar frequency range (20-27.9MHz) at 25 watts. I saw one for sale in an antique shop in Amsterdam once. 5 0 obj Main advantage over the FuG 5 was greater range. These things are built like tanks! << /S /GoTo /D (subsection.6.1) >> FuG 5: A high-band HF/low-band VHF transceiver. 80 0 obj It was usually used with a 1.4 metre antenna. During a siege on enemy territory, the Aztecs warriors would sound the "Death Whistle" in an effort to cause their . 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. It is a criminal offensive to hike the Stairs, and you could be fined a minimum of $1000 if you are caught. endobj On this Wikipedia the language links are at the top of the page across from the article title. Come on, there are a gazillion of those out there. 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. magopeter liked Water Meter Monitor with Raspberry Pi Pico W. itproducties.nl liked Global radiation monitoring network. I made a lot of contacts on it. 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. This office would be responsible for coordinating all of the purchasing and shipping of supplies (Woodbury, 1946:68). The FuG 2 was never used on its own but as an additional receiver in command tanks and relay devices. Olek has updated the project titled RelAC - Relay module for smart home appliances. One exception I removed the flower pot caps carefully with a soldering iron and dental pick/solder sucker to unwind the wires. And at the other end, the magnetron was developed allowing high power microwaves, mostly for radar. The project was one of hundreds that were completed under the coordination and leadership of the Pacific Naval Air Base (PNAB). ESR is an abbreviation for Equivalent Series Resistance, not Electrostatic Series Resistance. Excellent project. In 1923, the first transatlantic contact between amateurs in England and Connecticut occurred, opening up the world to long-distance communications. endobj 45 0 obj 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. 73 K9LJB. I connected up my 20 m external dipole and powered up the radio. I wonder if the Nazi's used Hertz? During the war this was extended to cover the majority of the occupied areas or Europe and North Africa. Radio-frequency identification ( RFID) has been around for over 80 years and has evolved into one of the most powerful technologies available for sample tracking and asset management. /Length 783 Just one thing about caps: ESR is not Electrostatic Resistance, its the Equivalent Series Resistance, Excellent posting and thanks for the dynamotor rebuild info. Fug 24: A 0.1 - 7.1MHz receiver paired with a 3 - 7.5MHz transmitter. Most places cant scan books without destroying the original unless you pay a fortune. I measured <1 uV on AM at 2 MHz, more than good enough for me and easily exceeding the original factory spec. WW2 Marconi ATR5 Radio Transmitter-Receiver Vintage WWII RCAF CMC Ham Tube Comm. Isnt ESR short for Equivalent Series Resistance? At this point I had two toggle switches and a pot with a mess of wire shoved into the rear panel connector pins. For example In regards to this topic any service manual or schematics, hopefully that have been hopefully digitized along the way. I know ATA ferry pilots had no radio, even on repaired planes, and was wondering how that was accomplished.

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. The receiver was not too sensitive, and tuning was jammed up at the higher frequency ranges on the dial. The radio could have been used in both. However, in 1938, there were also many officers and political leaders that sensed the seriousness of the rising turmoil in China and the growing interest of the Japanese in the Pacific, including Hawaii. If a capacitor failed, then it must be re-stuffed. Ground-to-air range 60km AM voice to 80km CW. 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. I then moved onto cleaning the Dynamotor. 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. No ham has ever laid a soldering iron or a drill bit to it. 9 0 obj I remember visiting a couple of friends (G4EYL and G8LUV) in the 80s, and they noticed some CBers on a ham band. 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. At this point in time the proposal for the Pacific Naval Air Bases was being limited to defensive measures. Crystals for daytime were the higher frequency ones. Very, very well done! Torn.Fu.h: A HF transceiver. In January of 1939 the Naval Affairs Committee opened hearings on the specifics of the proposed new Naval Bases. Range up to 100km. Hung-Yu David Yang, in The Electrical Engineering Handbook, 2005. That radio has an acceptance stencil from Alameda Naval Air Station endobj 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. Frequencies from 1-11 GHz are frequency bands where SAR imaging radars operate. Receivers use a single-conversion heterodyne architecture similar to that of big wood console radios of the era. At least replacement capacitors can be hidden on the underside of the chassis. Channel 2 8000 CPS teletype. Range 2km AM voice to 4km CW. Long range radio systems to communicate back to base, typically consisting of an ART-13 transmitter and a BC-348 receiver. https://mapsairmuseum.org/what-constitutes-a-radio-on-a-wwii-era-bomber/#:~:text=The%20predominate%20command%20installation%20during,5%20command%20series%20was%20used. Which one was this radio used it? Transmitters utilize a MOPA (Master Oscillator Power Amplifier) architecture supporting AM phone and CW (aka Morse code) transmission. A technician who modifies or hacks a radio to transmit on frequencies beyond its usual design parameters. One minor nitpick from the writeup F4F refers to a Wildcat, whereas a Hellcat uses the F6F designator. Along with the previously erected Naval station at Lualualei Valley was a naval communications station at Wahiawa, near Schofield Barracks. This is a testament to not replacing all the caps if you dont have to. There would be no bidding on the island contracts. Yes, its good to get a radio operational to its original specification. Channel 1 Voice or 5500 CPS teletype or three channels teletype. Ground. The basic wireless invention went through a rapid evolution between the first and second World Wars. Could interwork with the Fug 5 of the armour. 73 0 obj They are bitterly disappointing except for one surplus store that I found while on vacation in the Adirondacks: Patriot of Lake George. I applied 28V and, carefully with my finger, pushed the armature on the 28V side of the dynamotor to coax it into operation. .15 Watt output AM voice and CW. I have a 7mhz version of this receiver (black navy) that I used in my novice days in 1976. 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. 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. There were different systems for each specialized task: Somewhere in this menagerie of radio systems, you would find a CBY-46104 receiver. 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. He also had a BC-459 that he used on 40 meters. Used by the infantry. endobj It operated in the 42,000 to 48,300kHz (42-48.3MHz) frequency range with a transmission power of 20 Watts. Range approximately 10km with Cw and 3km with voice. (BBC Radio Signal Prediction) This was helped by the increasingly short supply of qualified Japanese pilots as well as the Zeros lack of performance compared to the Hellcat. I used these banana plugs to connect up the control panel and a 600 ohms speaker. Range up to 100km. Particularly the higher valued ones in the 100s of K or M ohm range. 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. In the 1920's and 1930's the Russians developed a number of radio-controlled systems. FuG 4: A medium-wave receiver used in command tanks. The US was the first to large scale field FM radios, as well as FM radio relay sets. This test will show if a cap is functioning as a cap and as specified. Frequency License Type Tone Alpha Tag Description Mode Tag; 143.700: M: USAF TB CC/Fuel: Cross Country/Refueling/Delta: AM: Military: 139.225: M: USAF TB Diamond: Diamond Formation 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. 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. This radio gear was light-weight for WW2 standards, the CBY-46104 weighs only 6 lbs and is made entirely from aluminum. It operated in the 27,000 to 33,300kHz (27-33.3MHz) range. Range 5km AM voice.[1]. I am familiar with these radios and have had a few of them in the past, but dont have any now. 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. 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. Tower up to 50 m. DM 43: Development item, possible none deployed. 13 0 obj There was a lot of noise coming through the speaker likely due to failed decoupling caps that would otherwise quiet the dynamotors hum. Mine came out of a old sheriffs car. Its just too bad that theres not as much to listen to in HF these days, unless one jumps into amateur radio. 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). Not intended to be used on the move. Could be used on the move with one man carrying the transmitter/receiver and the other the battery/power supply and handset. SO glad that the seller didnt touch it and you kept it as stock as possible! Short-range radio systems designed for aircraft-to-aircraft communication, known as command sets subdivided into a multitude of bands. FuG 13: A Fug 6 with two receivers rather than one. 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. DMG 3 K: Truck-mounted. Infantry. It was matched with the Luftwaffe transceiver Fug 17 in ground support operations. Instead of replacing the caps I opted to do a cursory check of the caps and try powering the unit up for an assessment.

Which Gen Set Manual do you have? Feldfu b: 90-110MHz Used by the infantry used in two versions. https://en.m.wikipedia.org/wiki/Paraset. Now there are so many easily modifiable kits and open source designs the remaining historical items are better off as museum pieces. And yes, Ive restored many WWII radios, and the peanut gallery is always annoying. Later, I built some crystal controlled converters and use the BC-453 as a tuneable IF. He taught me all about the command rx and tx. % Tower up to 50 m. Transmission power 0.4 Watts. More information including downloadable manuals here; http://radionerds.com/index.php/SCR-522 Anne Member for 14 years 3 months Imagine the stories it could tell! The BC-604 has a drawer with room for all the crystals for its frequency range. The huge, high powered antennas would send out stable, long waves that were able to travel long distances and penetrate intrusions, such as mountains and water. endobj During night time contacts the lower frequency crystals should be used. It was based on the British TR1143 and was used by the RAF as the TR5043. 89 0 obj Press J to jump to the feed. Channel 1, voice or 2400 CPS teletype. 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. After the war the codes were declassified and Ka band and millimeter (mm) were added. Also known a USW receiver c1. 2. A 1913 aircraft with a radio, at the time considered cutting-edge equipment, had a maximum range of 2,000 yards. 72 0 obj First Responders Interoperable Radio System Team (FIRST) Trunking System Profile. Post-WWII use continued for quite some time with AR-8510s showing up on old oil tankers as late as the 1980s. [2], Torn.Fu.f: A HF transceiver. With that said, ESR testing is useful for testing the electrolytic power supply capacitors in tube equipment. Big dynamotors explode in total awesomeness if you apply mains voltage to them. 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. Unfortunately some leaky capacitors will measure to their specified value, so this test is not definitive. Old resistors tend to increase in value over time. It's so enigmatic, it's as if it was designed with conspiracy theorists in mind. Nice job on the restoration. Workers hiked up the back side of the cliffs, from the Red Hill side, soon after the attack on Pearl Harbor. Cheers, W7PYX, Please be kind and respectful to help make the comments section excellent. These long-haul contacts led to 1927-1928 international conferences that resulted in the designation of what essentially are today's 80 . The Hellcat was of course better but that is only to be expected. It was usually used with a two-metre antenna. Its a long story, but an abused ARC5 dynamotor adapted for use powering an autopilot got me an interesting gig on a sailing yacht back in the 60s. The whrrrr was smoother than ever. FuSpr.f: A mid-band HF transceiver. Radio navigation receivers of various types from, glide slope receivers for landing purposes, and, TDOA radio navigation systems akin to modern GPS (except that you had to manually measure the time difference of arrival with an oscilloscope and line it up on special charts), such as. << /S /GoTo /D (section.4) >> 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. High voltage was generated from the Dynamotor. Learn how your comment data is processed. Ive become a believer in testing all the caps now. Electronic warfare receivers to detect enemy radar signals. << /S /GoTo /D (subsection.2.2) >> Used at the battalion to company level of the Panzergrenadier. endobj I bought it from a fellow in a wheel chair who had a shed full of surplus electronics. L.I.N.Y. The date of manufacture was early-war, February 1942. << /S /GoTo /D (section.2) >> 28VDC in, 250VDC out all the while spinning like a whirly-bird. U-Boats were cramped and had limited power. Fug 1: Also known as Torn.E.b And Pack Receiver b. I built capacitor packs that fit in the space and attached to the chassis with a solder lug. 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. Used by anti-tank units. England. Great write up. During this hearing Admiral Moreell laid out the exact method that would be used in building the bases. endobj Leakage testing is absolutely critical and must be done for each and every cap. 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. In modern low-voltage electronics the key metric to capacitor goodness is ESR. A Medium-wave receiver it operated in the 0,1 to 7,095kHz frequency range. That would be a good station to calibrate his dial on. It led to my career in electronics. Lastly, contracts should be paid a fixed fee instead of the conventional percentage of cost because it does not benefit the contractor to spend money but instead rewards him for not spending money (Woodbury, 1946:59). It was a fine radio for use on cw. https://www.youtube.com/channel/UCYQXlaLJRzzW9TYSynzOAvg. 36 0 obj Sadly the impact of this (significantly improved Command and Control of forces at the tactical level) gets virtually no 'airtime'. Most radios need every paper capacitor replacing, otherwise the leakage in them just destroys the resistor droppers, or blows up something else. 16 0 obj I dont know if they finally all sold out, or everything just got sent for scrap when Soviet surplus and post Soviet cheap optics and gear filled out the surplus pages during the 90s. To check each cap I had to remove each of them from circuit, one at a time. June 1940. of the 348) that my Dad used in the late 40s. 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. (Hops \046 Skip Zones) Shipboard antenna modeling uses brass models in a lead "sea". endobj FuG 9: A transceiver, operated in the 0.1 - 7.1MHz (100kHz - 7100kHz) range. 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.
