It operated in the 23,000 to 24,950kHz (23-24.95MHz) frequency range. endobj As long as they dont affect my person, family, friends, or our property, I dont care what others do with their property. FuG 16: A HF transceiver (receiver/transmitter) used in the command vehicles of Sturmartillerie units. The accessibility and availability meant it fueled propaganda and could reach a large number of citizens. 4 0 obj Power battery. Later a simplified version (b2), of lower power (.12w), was used by the Panzergrenadiers.[3]. endobj Tower up to 50 m. Transmission power 3.5 watts. The BC-604 has a drawer with room for all the crystals for its frequency range. I hooked up my 20m dipole and to my amazement I was tuning in AM broadcast stations at around 1500 Kc. By 1936, 4 million French citizens possessed a radio in their homes, with a choice of three main stations (Tour-Eiffel, Paris-PTT and Radio-Paris) as well as smaller private and provincial stations. 16 0 obj Or both? If a capacitor failed, then it must be re-stuffed. Torn.Fu.d2: A VHF transceiver. 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. endobj In the hearings of 1939 were stated several points that convinced skeptics of the decision to use this system of CPNAB. (Introduction) Fug 24: A 0.1 - 7.1MHz receiver paired with a 3 - 7.5MHz transmitter. Looking back at my own history, its clear that the kids toys were always the last priority in a move. The b version was used by the infantry until they changed to the 'c' model radio in another band. I was one of the youngsters who got an ARC-5 receiver in the mid 50s. EDIT: forgot to add that nearly all transmitters employed crystal-oscillators (wartime demands actually drove research to make leaps in radio crystal quality). There I found a unicorn of historical significance; an un-modified-since-WW2 surplus CBY-46104 receiver with dynamotor. These individuals, including Charles Edison as the Assistant Secretary of the Navy and Rear Admiral Ben Moreell, the head of the Bureau of Yards and Docks, met with President Roosevelt. 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. 2. 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. Number ranges were not unique across the services so sometimes different equipment used by different services had the same FuG prefix. sorry guys. Transmitters utilize a MOPA (Master Oscillator Power Amplifier) architecture supporting AM phone and CW (aka Morse code) transmission. FuG 13: A Fug 6 with two receivers rather than one. FuG 2: A high-band HF/low-band VHF receiver. It was matched with transceiver Fug 16 for use with Sturmartillerie (self-propelled artillery). It operated in the 23-28MHz frequency range. Fug 19: A transceiver operating in the range 3 - 7.5 Mhz. One of the tags has Signal Corps U.S. Army , can e-mail me for phone #. He taught me all about the command rx and tx. The FuG 2 was never used on its own but as an additional receiver in command tanks and relay devices. Big dynamotors explode in total awesomeness if you apply mains voltage to them. A typical practice of the post-WW2 era was for the Elmer hams to gift an ARC-5 receiver to a young ham working to earn their license. There seemed to b warehouses full of them up into the 80s along with a lot of other WWII stuff still around. 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. If a capacitor failed, then it must be re-stuffed. 41 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. News will be read in English, which the BBC. The Hellcat was of course better but that is only to be expected. Which Gen Set Manual do you have? Free shipping for many products! It operated in the 42,000 to 48,300kHz (42-48.3MHz) frequency range with a transmission power of 20 Watts. endobj Range up to 50km. I opted to remove the dead electrolytics and keep the old parts in a little paper bag. This office would be responsible for coordinating all of the purchasing and shipping of supplies (Woodbury, 1946:68).

How to make this low frequency radio system become reality was one of the most complicated jobs in the Pacific during the war. The Navy quickly decided to build a long range low frequency radio station in Hawaii using this type of natural resource. The wireless was invented by Marconi in the late nineteenth century and the Navy was quick to make use of the new technology. FuG 9: A transceiver, operated in the 0.1 - 7.1MHz (100kHz - 7100kHz) range. BETWEEN WW1 AND WW2 After the WW1 scientists continued researching of underwater radio communication. Torn.Fu.h: A HF transceiver. Used by anti-tank units. I applied 28V and, carefully with my finger, pushed the armature on the 28V side of the dynamotor to coax it into operation. 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. Later, I built some crystal controlled converters and use the BC-453 as a tuneable IF. FWIW according to the Tarrant ORB , 116.1mhz was the guard freq worldwide in 1946(That was DSB-AM- Amplitude Modulation). 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. Walkie-talkies even inspired a major cell phone network. 73 Mike AA9IL. They're all over the place. Test those capacitors before throwing them in the garbage and keep those filaments lit!

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 remember visiting a couple of friends (G4EYL and G8LUV) in the 80s, and they noticed some CBers on a ham band. Working towards the same goal, they slowly and stubbornly inched towards a proposal for Pacific Naval Bases (Woodbury, 1946: 65). The time station is WWV on 2.5 MHz exactly. 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. 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. M. Bindhammer has updated the log for Enhancer mask. Navy, 1947:401). 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. 0.7 Watt output AM voice and CW.

From this information shown on the navigators screen, a course to the target or as home run could be plotted. From 1936 the German forces started deploying a range of communication links using UHF frequencies to form a point-to-point mesh communication network. Learn how your comment data is processed. Low as 50v on the plates but diminished audio 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 is a measure of the effectiveness of a filter capacitor. During the war this was extended to cover the majority of the occupied areas or Europe and North Africa. 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. There are plenty. endobj Goebbels also used radio broadcasts to spread the word of Nazism abroad. Air to ground radio communication equipment. 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 could receive its output. . The Admiral proposed: . However, The radios would probably be near identical to CBs in their function, key differences being Freq Range, power- ect. Fug 20: A 0.1 - 7.1MHz receiver paired with a 1.1 - 3MHz transmitter. Thats a good suggestion and ive never thought of it before. I tend to have such a bad opinion of caps made since the mid 90s though, that I figure if I leave something in that seems marginal it still might last 5 years whereas a replacement might last 3. The station was highly experimental and also highly classified. So rule 1 fails immediately. Instead of replacing the caps I opted to do a cursory check of the caps and try powering the unit up for an assessment. 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. << /S /GoTo /D (subsection.2.2) >> endobj 65 0 obj Range approximately 10km with Cw and 3km with voice. endobj Could be used on the move with one man carrying the transmitter/receiver and the other the battery/power supply and handset.

Today surplus stores only have contemporary Chinese-made boots, camping gear, and flashlights. This test will show if a cap is functioning as a cap and as specified. It was running but not well. Occasionally the shorted Fu designation were used and there were exceptions to both these systems. 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. Great write up. It was used with a two-metre antenna. https://en.m.wikipedia.org/wiki/Paraset. Post-WWII use continued for quite some time with AR-8510s showing up on old oil tankers as late as the 1980s. First Responders Interoperable Radio System Team (FIRST) Trunking System Profile. To check each cap I had to remove each of them from circuit, one at a time. 3. 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. Unfortunately some leaky capacitors will measure to their specified value, so this test is not definitive. Very nice restoration! 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). Stephen Chasey liked LIDL PARKSIDE Battery hacks.

Endnotes: Chapter 3. Second, the contracts were awarded to large firms because small ones did not have the experience or talent for this large scale operation. Its a real shame it cant communicate anymore because it uses megacycles. 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. Near exclusively AM mode. Usually they used 30.xx MHz area frequencies (low band, radios close to 10 meters) AM mode usually. When they did not have enough time to gain altitude they had catastrophic losses. He also had a BC-459 that he used on 40 meters. Replacement for Torn.Fu.g.[3]. They are bitterly disappointing except for one surplus store that I found while on vacation in the Adirondacks: Patriot of Lake George. It was first used in combat early in 1944 on the Anzio beachhead in Italy. (Episodes of Nazi-fascist violence) Its just too bad that theres not as much to listen to in HF these days, unless one jumps into amateur radio. Took first prize in my category! Nice work on the restoration. << /S /GoTo /D (subsection.4.4) >> (Fug 8 + Fug 4). Ive become a believer in testing all the caps now. Sound torture is nothing new. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 30 Watts. In particular they questioned how the wires would be brought to the top of the ridge from the Valley side. These were usually early-model tanks with some of their armament removed and replaced by equipment for artillery observers. All receiver dials, prior to WWII, were vague in accuracy and didn't provide . The electrolyics, however, were extremely leaky and did not reform. In modern low-voltage electronics the key metric to capacitor goodness is ESR. In fact, using sound to psychologically attack an enemy has roots in the ancient Aztec culture. The first decade of FM broadcasting, starting in 1936 to 1946, occurred in the 42 - 50 MHz band. Nice work. Torn.Fu.c: A HF transceiver.

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. Very nice rebuild, a lot of patience to test each capacitor multiple ways. 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. A radio user who intentionally transmits communications on unauthorized spectrum outside the limits of a normal channel frequency or band. Used by the infantry.
