FuG 7: A VHF transceiver (receiver/transmitter) used in command tanks. endobj Ground-to-air range 60km AM voice to 80km CW. June 1940. Amazing for resistors built before February of 42. I was a bit surprised at how the caps actually tested. We are now at a point where the surplus WW2 electronics should no longer be hacked to bits. In comparison, there's a morning Ohio rag chew net that operates on 28.337 MHz, Monday-Friday at 8:30 am. VHF frequency is widely used in analog TV broadcasting since it started a few decades back. 28 0 obj Come on, there are a gazillion of those out there. The CPNAB had an interest in Haik Valley as soon as the war broke out. Learn how your comment data is processed. Range approximately 10km with Cw and 3km with voice. The BC-604 has a drawer with room for all the crystals for its frequency range. It was used with antenna of either 1.4 to 2.0 metres antenna. That radio has an acceptance stencil from Alameda Naval Air Station At this point in time the proposal for the Pacific Naval Air Bases was being limited to defensive measures. Used by artillery observers. Im totally on your side generally; but its really not a crime to play around with gear like that and drill some holes. The B-17 was the work horse of high altitude heavy bombers when the United States entered World War II. Single-unit "walkie-talkie" system. Yes, its good to get a radio operational to its original specification. It was usually used for communication with a Fug 8 in the same installation. After much deliberation and intensive screening three companies were determined to be the strongest competitors having knowledge, experience, and imagination. 88 0 obj Later a simplified version (b2), of lower power (.12w), was used by the Panzergrenadiers.[3]. I agree with the sentiment about not hacking, but restoring these venerable veterans. This wasnt restoration though, it was trying to get the last few cents worth of service out of ancient crap for as little additional investment possible. [3], Torn.Fu.k: A HF transceiver. endobj Receiver probes are inserted from a room underneath the model while test signals are transmitted from the gantry. Leakage testing is absolutely critical and must be done for each and every cap. 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. This article is a list and a description of the radio equipment. . (Introduction) There are plenty. (Acronyms) It could be powered by 12 or 24v dynamotors. 20 0 obj Over one hundred firms applied to be the Contractors used for the Pacific Naval Bases. This radio came in at 181 pounds. I did make one modification to it: I added a pot to dial in some positive feedback around 2 of the IF stages. << /S /GoTo /D [90 0 R /Fit] >> << /S /GoTo /D (subsubsection.4.4.1) >> I saw one for sale in an antique shop in Amsterdam once. https://en.m.wikipedia.org/wiki/Paraset.

Nice work on the restoration. I was one of the youngsters who got an ARC-5 receiver in the mid 50s. In Hawaii,Navy communications began in September, 1916, at Hospital Point, Pearl Harbor. A radio user who intentionally transmits communications on unauthorized spectrum outside the limits of a normal channel frequency or band. I re-connected it the correct way and it worked just as well as it did before. FuG 6: A high-band HF/low-band VHF transceiver. Dynamotor worked perfectly, just like new again! (Very Low Frequency band, VLF). Very cool! Operating on the 1250 - 1390MHz band, two channels. The parasets the British SOE sent to operatives in occupied Europe used low HF, 3-7 MHz. If a capacitor failed, then it must be re-stuffed. Infantry. It was first used in combat early in 1944 on the Anzio beachhead in Italy. 57 0 obj Feldfu b: 90-110MHz Used by the infantry used in two versions. Range 2km AM voice to 4km CW. I remember visiting a couple of friends (G4EYL and G8LUV) in the 80s, and they noticed some CBers on a ham band. 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. endobj 0.7 Watt output AM voice and CW. endobj Air to ground radio communication equipment. To prevent enemies from noticing it, most fighters hide the device in a sock. A leaky cap will act like a high value resistor, in the many-multi-mega ohm range thereby reverse-biasing the grids of tubes or discharging itself causing it to not function like a capacitor at all. 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. The Aztec "Death Whistle" served a variety of purposes from human sacrifice rituals to warfare. It needs some work too. A true restoration, not a replace old carcass with modern guts restoration like weve been so used to seeing. That would be a good station to calibrate his dial on. These things are built like tanks! 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). Those old caps still working is amazing, and a testament to just how terrible the knockoff electrolytic caps are. It was used for communication back to the regimental command post. This office would be responsible for coordinating all of the purchasing and shipping of supplies (Woodbury, 1946:68). 2. SO glad that the seller didnt touch it and you kept it as stock as possible! During night time contacts the lower frequency crystals should be used. A Medium-wave receiver it operated in the 0,1 to 7,095kHz frequency range. All paper/wax capacitors were fine. It is a measure of the effectiveness of a filter capacitor. I found a video on servicing a similar motorand proceeded to strip mine down, clean out the old grease in the bearings, put new grease into the bearings, clean the armatures, and re-assemble. This test will show if a cap is functioning as a cap and as specified. It operated in the 24.1 to 25MHz (24100 to 25000kHz) frequency range with a transmission power of 5 Watts. R1155 frequency range: 75 kHz to 18.5 MHz depending on the model variant. WW2 Marconi ATR5 Radio Transmitter-Receiver Vintage WWII RCAF CMC Ham Tube Comm. Production on the SCR-536 radio began in July of 1941, and approximately 130,000 of them were built by Galvin Manufacturing Co./Motorola of Chicago, Illinois. Like weather frequencies, the Ham net frequencies also vary from state to state. Unit must run off of its dynamotor, as it was intended. With all of this I made a neat wire harness to tie it all together. And I used an external home brew power supply and soldered directly to pins. It operated in the 32-38MHz frequency range. At that time, the mood of America was one of caution. 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. 17 0 obj I hooked up my 20m dipole and to my amazement I was tuning in AM broadcast stations at around 1500 Kc. So rule 1 fails immediately. 52 0 obj This unit was also used by motorcycle troops in the first half of the war. Cheers, W7PYX, Please be kind and respectful to help make the comments section excellent. 25 0 obj The station would be able to obtain long range signals because it would use a very low frequency. The museum ships often have fully operational radio rooms wherein folks make the old radio gear work again. How to make this low frequency radio system become reality was one of the most complicated jobs in the Pacific during the war. There seemed to b warehouses full of them up into the 80s along with a lot of other WWII stuff still around. Of course I am not proud of that today. It consists of a few dials and a very sensitive Magic Eye tube which will deflect leakage is detected. << /S /GoTo /D (subsubsection.2.2.1) >> Along with the previously erected Naval station at Lualualei Valley was a naval communications station at Wahiawa, near Schofield Barracks. People were very hesitant to become involved in another war, particularly if America was not directly involved. Most radios need every paper capacitor replacing, otherwise the leakage in them just destroys the resistor droppers, or blows up something else. FuG 8: A medium-wave transceiver (receiver/transmitter) used in command tanks. A system was needed that could send messages to the bottom of Tokyo harbor. More to the point, how might the workers themselves reach the top of the ridge (Wainwright, 1997). . 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. Big dynamotors explode in total awesomeness if you apply mains voltage to them. In some command units. 89 0 obj Old resistors tend to increase in value over time. Aviation Distress (VHF Guard) 118.000 - 121.950 MHz. On May 25th, 1939 Congress passed an appropriation bill providing 63 million dollars for Naval Air Bases. Channel 1 control channel voice, Channel 2 nine voice channels or p x 3 Teletype. << By 1940, the Naval communication system included technology capable of high, medium, and low frequencies that could send signals out to all corners of the globe (U.S. Dept. 73, gary/NJ8BB. and deployed operationally in 1941 in the "Great Patriotic . (Tactical Information \(non-coded\)) 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 . Channel 1, voice or 2400 CPS teletype. The SCR-584 operated in the frequency range from 2.7 to 2.9 GHz (known as the S band) and had a parabolic reflector antenna with a diameter of nearly 6.6 feet (2 metres). The whrrrr was smoother than ever. In the World War II context, HF/DF applied to direction-finding of radio communications transmitters, typically operating at high frequency (HF). Remarkably enough, the vast majority of these Feb 1942 capacitors tested good. When they did not have enough time to gain altitude they had catastrophic losses. Long-distance ham radio communications began in the 1920s. It was usually used with a 1.4 metre antenna. I know ATA ferry pilots had no radio, even on repaired planes, and was wondering how that was accomplished. FuG 13: A Fug 6 with two receivers rather than one. ( Critical frequency, LUF/MUF, Hops e Multipath) Aircraft used a variety of frequencies. Used by the infantry. The first decade of FM broadcasting, starting in 1936 to 1946, occurred in the 42 - 50 MHz band. Comparable to the American SCR-508 tank radio, which covered a similar frequency range (20-27.9MHz) at 25 watts. endobj One minor nitpick from the writeup F4F refers to a Wildcat, whereas a Hellcat uses the F6F designator. No replacement of any components whatsoever. endobj It operated in the 27,000 to 33,300kHz (27-33.3MHz) range. It was usually used with a two-metre antenna. stream DMG 3 K: Truck-mounted. It was used with the same antenna as the Fug 8. In the hearings of 1939 were stated several points that convinced skeptics of the decision to use this system of CPNAB. endobj /Filter /FlateDecode 81 0 obj magopeter liked Flipper Zero Multi-tool Device for Hackers. Looking back at my own history, its clear that the kids toys were always the last priority in a move. Range 70km AM voice to 200km CW. Imagine the stories it could tell! 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. << /S /GoTo /D (subsubsection.4.4.4) >> The ghostly radio station that no one claims to run - BBC . How the lineage of the walkie-talkie reaches from World War II to the modern cell phone. 41 0 obj It is probably more authentic after a good re-capping and re-alignment. Formed the base design of other units. The Navys radio station installations grew rapidly. Repackaged for use in several other receivers and transceivers. 3. A 1913 aircraft with a radio, at the time considered cutting-edge equipment, had a maximum range of 2,000 yards. (LUF \046 MUF) No replacement of any components whatsoever. Post-WWII use continued for quite some time with AR-8510s showing up on old oil tankers as late as the 1980s. 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. ahh jeez, that was meant at top level, idk how it ended up as a comment 3 levels down. 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. 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. At this point I had two toggle switches and a pot with a mess of wire shoved into the rear panel connector pins. (BBC Medium Wave and Short Wave Broadcasting) It operated in the 23.11 to 24.01 MHz (24100 to 25000kHz) frequency range with a transmission power of 5 Watts. It drives me nuts to see someone take something that should be in a museum and butcher it. 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. endobj It operated in the 3-5MHz frequency range. Unfortunately, I did modify the chassis to accommodate some kind of tuning knob and vernier in an attempt to slow down the tuning rate for cw. One of the forerunners for this technology was the revolutionary electrical musical instrument developed by Leon Theremin. Olek has updated the project titled Fan Controller. Power 220 V AC 50Hz. FuSpr.d: A mid-band HF transceiver. The radio could have been used in both. 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. Additional information about the FCC's table of frequency allocation is available in the Commission's rules. xUMs6W`zgLO4Q*LhV1#.EN}H^bdC8O30D(fz SyN@UM_ci'v~:~fCa0$,DZVln?T oznbw>_P%\LxJ1n$IqTrh#yk(?,{9(43IzcC/pyhs90+1s4 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. U-Boats were cramped and had limited power. 0uXA{z2{w Im surprised. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 100 Watts. I like old military shortwave radios. It spun up like a 1950s jet engine! 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. Very, very well done! Transmission power 0.15 watt. The F4F was the Wildcat the F6F was the Hellcat. A projectile hit the . I think its laudable that he kept the mods and replacements to a minimum. Over the next three years the contracts given the CPNAB grew to be the largest contractual award in history. I measured <1 uV on AM at 2 MHz, more than good enough for me and easily exceeding the original factory spec. FuG 12: A medium-wave transceiver (receiver/transmitter) used in command tanks. It was usually used with a two-metre antenna. $79.99 When we were young; in the 70s; we destroyed literally tons of stuff like that just for fun. B^). FuSpr.f: A mid-band HF transceiver. 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. Rule 3. is generally totally incompatible with rule 1. But one might ask, with 28VDC input, how do we get high voltage for the vacuum tube plates? Here is how they did it in WW2: This unit has what is known as a Dynamotor. qk|UbVE4k%3DsRaEAYsombT_FG46m,@0E/N7U. %PDF-1.5 Torn.Fu.a: A HF transceiver. .15 Watt output AM voice and CW. 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. On this Wikipedia the language links are at the top of the page across from the article title. In 1920 a receiver station was constructed at Wailupe. I tested the electrolytic and paper caps with a Fluke DVM in resistance mode for obvious shorts or low impedance. endobj I used to have a transceiver built in the U.S. for use in Russian tanks, during WWII. Today the . FuG 11: A medium-wave transceiver (receiver/transmitter) used in command tanks. I used to be all about modding things to unrecognizability but that was when new gear was so much more expensive. FuG 5: A high-band HF/low-band VHF transceiver. It operated in the 23,000 to 24,950 kHz (23-24.95 MHz) frequency range with a transmission power of 10 Watts. A compromise has to be made you can either leave a radio totally original, OR you can have it working to its original specification. I built capacitor packs that fit in the space and attached to the chassis with a solder lug. 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.

(Critical frequency) Power 220 V AC 50Hz 680 VA. Stuttgart - FuG D 3: Development item, possible none deployed. The Army had three major and several minor radio installations. Specialized Mobile Radio (SMR): Also see Enhanced Specialized Mobile Radio ( ESMR ). The chances of doing that without replacing any components is probably around 1% for radios of this vintage and I have done dozens of them over some 26 years. Also known a USW receiver c1. FuG 10: A medium-wave transceiver (receiver/transmitter) used in command tanks. BETWEEN WW1 AND WW2 After the WW1 scientists continued researching of underwater radio communication. I wonder if the Nazi's used Hertz? << /S /GoTo /D (section.1) >> And yes, Ive restored many WWII radios, and the peanut gallery is always annoying. Radio was the cheapest form of entertainment, and it was the most popular medium during World War II. endobj 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. Otherwise, you should probably ask around in the area in which you plan to operate. endobj So, I suppose in WWII it would have been Baker!) Sadly the impact of this (significantly improved Command and Control of forces at the tactical level) gets virtually no 'airtime'. Range 1.5km. 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. Nice! 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. Otherwise identical to Torn.Fu.b. These were usually early-model tanks with some of their armament removed and replaced by equipment for artillery observers. It operated in the 1.87 - 3MHz frequency range. One exception I removed the flower pot caps carefully with a soldering iron and dental pick/solder sucker to unwind the wires. of the 348) that my Dad used in the late 40s. Long range radio systems to communicate back to base, typically consisting of an ART-13 transmitter and a BC-348 receiver. Thereafter version b1 was used by the Pioneers. It was usually used with a two-metre antenna. 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. It operated in the 2.5-3.5MHz frequency range. 73 K9LJB. << /S /GoTo /D (section.6) >> It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 30 Watts.
