Maybe 160 meter AM net? I tested the electrolytic and paper caps with a Fluke DVM in resistance mode for obvious shorts or low impedance. Very, very well done! endobj 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 audio amp tube socket is a problem. 48 0 obj It operated in the 33.8-38MHz frequency range. By Ernie Smith Aug 17, 2017 Filed under: cell phones, kiddie talkie, , push-to-talk, radio technology, two-way radio, walkie talkie, wireless spectrum, world war ii Occasionally the shorted Fu designation were used and there were exceptions to both these systems. Used by the infantry. endobj endobj Various radios were used for clandestine communications by resistance groups in WWII, including the Norwegian OLGA and the British Paraset, which was supplied to resistance groups in France, Belgium, and the Netherlands. 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. I built capacitor packs that fit in the space and attached to the chassis with a solder lug. Formed the base design of other units. FuG 11: A medium-wave transceiver (receiver/transmitter) used in command tanks. 9 0 obj endobj Infantry. 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). It is a carefully balanced chassis/radio design for weight minimization (these were installed in aircraft after all) while also remaining rugged and able to provide stable operation across MIL-SPEC temperature ranges and intense vibration. It operated in the 3-5MHz frequency range. Its a real shame it cant communicate anymore because it uses megacycles. Depending on the set a range of communication facilities were available consisting of voice and/or teletype and Hellscriber. There seemed to b warehouses full of them up into the 80s along with a lot of other WWII stuff still around. When they did not have enough time to gain altitude they had catastrophic losses. 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. Usually they used 30.xx MHz area frequencies (low band, radios close to 10 meters) AM mode usually. Press question mark to learn the rest of the keyboard shortcuts. << /S /GoTo /D (section.3) >> 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. In 1931 land was bought in Lualualei Valley for the purpose of constructing a new transmitter facility. DMG 3 K: Truck-mounted. Sets employing frequency modulation and carrier techniques were developed and used, as were also radio relay sets that used radar pulse transmission and reception techniques and multiplex time-division methods for obtaining many voice channels from one radio carrier. have extremely high DC impedance) at high voltages. Sadly, it disappeared in one of my folks moves. << /S /GoTo /D (section.1) >> The BBC says its shortwave broadcasts will be available on frequencies of 15735 kHz from 4PM to 6PM and 5875 kHz from 10PM to midnight, Ukraine time. Depends on the service. Dynamotor worked perfectly, just like new again! BBC revives shortwave radio dispatches in Ukraine, and draws ire of Russia. (Hops \046 Skip Zones) 72 0 obj Very cool! Look . I wonder if the Nazi's used Hertz? Instead of replacing the caps I opted to do a cursory check of the caps and try powering the unit up for an assessment. noun. It is a measure of the effectiveness of a filter capacitor. 41 0 obj This radio transmitter was 25 watts and had a range of 7 miles moving, and 10 to 15 while stopped. 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. Channel 1, voice or 2400 CPS teletype. It operated in the 23-28MHz frequency range. It was used with the same antenna as the Fug 8. Range up to 100km. The date of manufacture was early-war, February 1942. I was also surprised by the quality of the caps in my WS19. DVM testing only reveals the short-circuited caps, this is a necessary first step. No holes can be drilled, either on the chassis or on the plug-in. endobj 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 results were actually quite nice. The K series were truck mobile units using a range of masts up to approximately 11 m tall. Next I had to locate documentation. Remarkably enough, the vast majority of these Feb 1942 capacitors tested good.

The project was one of hundreds that were completed under the coordination and leadership of the Pacific Naval Air Base (PNAB). In the hearings of 1939 were stated several points that convinced skeptics of the decision to use this system of CPNAB. Test those capacitors before throwing them in the garbage and keep those filaments lit! Unit must be made fully operational to original specification. Anyone have some cool facts to share? Fug 18: Group of radios covering 25 - 77.1 Mhz Fug 19: A transceiver operating in the range 3 - 7.5 Mhz. 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. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 30 Watts. << /S /GoTo /D (section.6) >> With good resistors, good caps, a working dynamotor I then moved onto the tuning mechanism. Within the VHF aviation communication frequency range, the most commonly used frequencies and their corresponding allocations include: Frequency. But if you have an old frequency generator also marked in cps, Feldfu f: 28.0 - 33.0MHz Panzergrenadier. There is a Museum ships radio contest once per year, ships will operate CW and AM with the old gear and plug in a modern transceiver to operate SSB. 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. 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. Not both. After the war the codes were declassified and Ka band and millimeter (mm) were added. Some command and reconnaissance units had this infantry transceiver to allow then to talk to Panzergrenadier units.[2]. 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. 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). I can do 36-inch wide scans and prints from a plotter if needed. On this Wikipedia the language links are at the top of the page across from the article title. https://en.m.wikipedia.org/wiki/Paraset. ( Critical frequency, LUF/MUF, Hops e Multipath) Like weather frequencies, the Ham net frequencies also vary from state to state. There would be no bidding on the island contracts. 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. Power 220 V AC 50Hz 680 VA. Stuttgart - FuG D 3: Development item, possible none deployed. Radio Communications in World War II Naval radio communication played a vital role in World War II efforts and Hawaii's defensive installation. The Role of Radio in Wartime France. The museum ships often have fully operational radio rooms wherein folks make the old radio gear work again. The model is 1/48 scale and the frequencies used are 48 times higher than actual. No, X86 Single-Board Computer! 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. and deployed operationally in 1941 in the "Great Patriotic . Nicely done. Oh BTW I think reforming is only a thing since ITT came out with the first thin foil caps, such that the conductive layer was thin enough to burn out around a short. 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. endobj 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? endobj Operating on the 500 - 560MHz band, two channels. It wont be factory original but will represent the era. Reddit and its partners use cookies and similar technologies to provide you with a better experience. I have a BC-348/Q5er (BC453 w/ front-end mods to tune to the 915 KHz I.F. EDIT: forgot to add that nearly all transmitters employed crystal-oscillators (wartime demands actually drove research to make leaps in radio crystal quality). I used to be all about modding things to unrecognizability but that was when new gear was so much more expensive. He also had a BC-459 that he used on 40 meters. Transmitters utilize a MOPA (Master Oscillator Power Amplifier) architecture supporting AM phone and CW (aka Morse code) transmission. I used to have a transceiver built in the U.S. for use in Russian tanks, during WWII. Transmission power 0.15 watt.

Sadly this is no longer the case. Great write up. RFID - Radio-Frequency Identification - uses electromagnetic fields to identify and track objects which carry either a passive or active tag. Learn how your comment data is processed. Could this unit have seen some action in the south Pacific? FuG 7: A VHF transceiver (receiver/transmitter) used in command tanks. 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. endobj (Very Low Frequency band, VLF). Operating on the 600 - 650MHz band, two channels. The contract for this run was #74812 dated June 29, 1940, demonstrating the ramp-up in war materiel purchasing/production in advance of Pearl Harbor. Unfortunately some leaky capacitors will measure to their specified value, so this test is not definitive. endobj News will be read in English, which the BBC. 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. Fug 18: Group of radios covering 25 - 77.1 Mhz. 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. of the 348) that my Dad used in the late 40s. Feldfu c: 130 - 160MHz infantry. Radio during WWI At the onset of World War I, radio was still in its infancy. Macona: Sadly, it disappeared in one of my folks moves., Did it occur to you, that is maybe why they moved as often as they did? (LUF \046 MUF) The whrrrr was smoother than ever. Come on, there are a gazillion of those out there. FuG 8: A medium-wave transceiver (receiver/transmitter) used in command tanks. There are also other frequencies allowed based on location (Hawaii, Los Angeles, and the Grand Canyon). endobj WW2 Marconi ATR5 Radio Transmitter-Receiver Vintage WWII RCAF CMC Ham Tube Comm. Which one was this radio used it? SCR-536 This device was used by the U.S. Army during World War II. All receiver dials, prior to WWII, were vague in accuracy and didn't provide . It operated in the 2.5-3.5MHz frequency range. Eric Steven Raymond So rule 1 fails immediately. Looking back at my own history, its clear that the kids toys were always the last priority in a move. 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. Its just too bad that theres not as much to listen to in HF these days, unless one jumps into amateur radio. 56 0 obj Olek has updated the project titled RelAC - Relay module for smart home appliances. The new receiving station at Wahiawa amply met these requirements but the main Navy transmitter at Lualualei was not powerful enough for an all-ocean war. It operated in the 4247.8MHz range. It operated in the 4.5-6.67MHz frequency range. Erythrocyte Sedimentation Rate. A compromise has to be made you can either leave a radio totally original, OR you can have it working to its original specification. At this point in time the proposal for the Pacific Naval Air Bases was being limited to defensive measures. Naturally their foray into military-technology innovation affects the way defense satellites are designed in the next half-century. England. First Responders Interoperable Radio System Team (FIRST) Trunking System Profile. The ghostly radio station that no one claims to run - BBC . The Admiral proposed: . I then moved onto cleaning the Dynamotor. 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. No replacement of any components whatsoever. The Wildcat was completely outclassed by the Zero, which enjoyed a 12:1 kill ratio over American planes at the beginning of the war; with the exception that the Wildcat was amazingly durable. Besides if you really want the original experience.. it didnt have 70 year old caps in it 70 years ago! Radio helped entertain and inform the population, encouraging citizens to join in the war effort. Pomeroy and Company, Inc. On July 11th, 1940, a new bill was approved (Woodbury, 1946:140). M. Bindhammer has updated the log for Enhancer mask. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 80 Watts. 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. Of course I am not proud of that today. I opted to remove the dead electrolytics and keep the old parts in a little paper bag. FuG 4: A medium-wave receiver used in command tanks. /Filter /FlateDecode 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). I measured <1 uV on AM at 2 MHz, more than good enough for me and easily exceeding the original factory spec. The station would be able to obtain long range signals because it would use a very low frequency. These were usually early-model tanks with some of their armament removed and replaced by equipment for artillery observers. That increased both the gain and the selectivity of the radio. endobj One exception I removed the flower pot caps carefully with a soldering iron and dental pick/solder sucker to unwind the wires. Officially the only people who were allowed to listen to foreign broadcasts were the SS and Abwehr (army intelligence) for intelligence purposes and members of the Nazi Party who were given special permission to use more powerful radios to listen out for and disown Allied propaganda. Im surprised. 17 0 obj Mine came out of a old sheriffs car. I think you did a great restoration just a pity about nonsensical rules! Range up to 100km. It operated in the 27,000 to 33,300kHz (27-33.3MHz) range. At least replacement capacitors can be hidden on the underside of the chassis. Bravo! Create an account to follow your favorite communities and start taking part in conversations. Operating on the 475 - 525MHz band, two channels. Otherwise identical to Torn.Fu.b. endobj Long-distance ham radio communications began in the 1920s. (Comment Policy). The problem with these crystals was, that frequencies of the radio nets were planned frequencies for day and night time, just for all the 24 hour. If a capacitor failed, then it must be re-stuffed. Fug 25: A 2.5 - 27.5MHz receiver paired with a 3 - 16.6MHz transmitter. Radio. The instrument could be . It was based on the British TR1143 and was used by the RAF as the TR5043. I have one receiver with the dyno I run stock and the caps appear fine so I left them in. Fug 19: A transceiver operating in the range 3 - 7.5 Mhz. 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. 52 0 obj Now that everything was in order it was time to try the radio in its final configuration. 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. As with every other aspect of the entertainment industry, the government had a firm grip on radio stations, which led to censoring many of their programs.

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. Of course, they called them megacycles, rather than MHz. Im also in agreement to not drill holes or modify per the surplus conversion handbooks Reconnaissance units later in the war. P-47s and all other USAAF fighters operating from the UK would have been fitted with the SCR-522-A VHF radio operating between 100-156 Mcs. Not reversible. A projectile hit the . There were different systems for each specialized task: Somewhere in this menagerie of radio systems, you would find a CBY-46104 receiver. I found mine at the Dayton Hamvention many years ago for $10. In 1920 a receiver station was constructed at Wailupe. Replacement for Torn.Fu.f. << /S /GoTo /D (section.5) >> Hung-Yu David Yang, in The Electrical Engineering Handbook, 2005. Next I checked all of the resistors with my Fluke DVM. Great project! The Hellcat was of course better but that is only to be expected. 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. Chapter 10 discusses the principle of both pulsed and CW radar systems and radar parameters. Tower up to 50 m.

(The \215Special Messages\216 \(Coded Messages\)) Sadly the impact of this (significantly improved Command and Control of forces at the tactical level) gets virtually no 'airtime'. Frequencies around the 13-18 GHz band is where precipitation radars generally operate. 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). I tweaked the antenna coupling control, they were louder still. endobj 2. 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. Now there are so many easily modifiable kits and open source designs the remaining historical items are better off as museum pieces. High voltage was generated from the Dynamotor. That connector full of separate banana jacks is just screaming for a 3D printed jig to hold them all together. 29 0 obj Sound torture is nothing new. It was used by armoured observation posts. The frequency range was (Mc) 20 to 27.9. 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. This test will show if a cap is functioning as a cap and as specified. << /S /GoTo /D (subsubsection.2.2.1) >> During this hearing Admiral Moreell laid out the exact method that would be used in building the bases. First Responders Interoperable Radio System Team (FIRST) Trunking System Profile . 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. magopeter liked Flipper Zero Multi-tool Device for Hackers. I saw one for sale in an antique shop in Amsterdam once. And I used an external home brew power supply and soldered directly to pins. Old radios are like old cars, they could use an alignment from time to time. Thereafter version b1 was used by the Pioneers. Ground. Remarkably enough, the vast majority of these Feb 1942 capacitors tested good. 1. 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. 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 . It operated in the 32-38MHz frequency range. There are plenty. 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. It operated in the 23.11 to 24.01 MHz (24100 to 25000kHz) frequency range with a transmission power of 5 Watts. Panzergrenadier units. I figured out the problem after about five minutes of reverse polarity operation. How the lineage of the walkie-talkie reaches from World War II to the modern cell phone. It could receive its output. FuSpr.a: A mid-band HF transceiver. 24 0 obj Military radar band nomenclature is widely used today in radar . I never played with the transmitters very much. It was a fine radio for use on cw. Of course, it had a dynamotor power supply, which we used to (only half jokingly) refer to as a rotating short. I did that once with a couple of books and used OCR software on the images to create a searchable PDF. Power battery. I wonder if the Nazi's used Hertz? 77 0 obj In my experience, the dynamotors were often the first thing to be discarded on those sets. This radio came in at 181 pounds. Range 2 km AM voice to 4 km CW. << And of course lets not forget the legendary Collins ART-13 with auto-tune. I was a bit surprised at how the caps actually tested. During night time contacts the lower frequency crystals should be used. Feldfu.a1: 120-156MHz infantry, a VHF transceiver. It is a criminal offensive to hike the Stairs, and you could be fined a minimum of $1000 if you are caught. Section 2.104 provides information about the International Table while Section 2.105 contains information regarding the US Table of Frequency Allocations. endobj Used by artillery forward observers. But now with what you have done, I will go thru the receiver completely. The list of radio systems installed into WW2 aircraft goes on and on, even more so for special aircraft like night fighters which depended entirely on radio navigation and radar systems to fly their missions and jamming aircraft whos purpose was to hide fleets of bombing aircraft or invasions of coastal territories. Was present in almost all German tanks and some other vehicles. 25 0 obj 33 0 obj Logistics were quickly decided upon and offices began to function. 53 0 obj Now *that* is how you do a restoration! Fug 24: A 0.1 - 7.1MHz receiver paired with a 3 - 7.5MHz transmitter. Nice work. It drives me nuts to see someone take something that should be in a museum and butcher it. (Air Drops) The dynamotor roared into life but the radio never produced audio. 21 0 obj Identical to Torn.Fu.b with exception of frequency range. Clandestine Radios of WWII - EEWeb Community Still others operated radio frequency heaters and sealers being used in an expanding number of industries using technology developed during World War II. 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). Frequencies from 1-11 GHz are frequency bands where SAR imaging radars operate. Allocation. Range up to 50km. Then noise came out of the speaker. Today surplus stores only have contemporary Chinese-made boots, camping gear, and flashlights. The "Backpack" or Torn series and the field or Feld series. Low as 50v on the plates but diminished audio a.m. at frequencies within the 1-10 MHz range . 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. It was used with various antenna ranging from 1.8 to 9-metre antenna. Used at the battalion to company level of the Panzergrenadier. endobj I agree with the sentiment about not hacking, but restoring these venerable veterans.

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. Torn.Fu.b: A HF transceiver. A cable linked the two men together. 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. the vital issue of using private contractors to do the work in the pacific. At that time, the mood of America was one of caution. 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. [3], Torn.Fu.k: A HF transceiver. Im totally on your side generally; but its really not a crime to play around with gear like that and drill some holes.
