Amazing for resistors built before February of 42. For example In regards to this topic any service manual or schematics, hopefully that have been hopefully digitized along the way. Feldfu d: 32 - 38MHz Artillery Observers. 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. By accident I even connected the DC input backwards, reverse polarity. And yes, Ive restored many WWII radios, and the peanut gallery is always annoying. In 1936 the Lualualei Valley transmitter was activated (HABS, 1997:6). /Filter /FlateDecode The station would be able to obtain long range signals because it would use a very low frequency. It drives me nuts to see someone take something that should be in a museum and butcher it. Channel 2 6000 CPS teletype. Another system, and the subject of this blog piece, was the F-10 radio-controlled mine. Used by anti-tank units. 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. The K series were truck mobile units using a range of masts up to approximately 11 m tall. It operated in the 4247.8MHz range. Channel 2 8000 CPS teletype. They're all over the place.

Consisting of an RFID reader and transponder, RFID systems can include multiple tags (antennae paired with a microchip) that can send out . 45 0 obj FuG 10: A medium-wave transceiver (receiver/transmitter) used in command tanks. 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 . Range 70km AM voice to 200km CW. endobj In 1920 a receiver station was constructed at Wailupe. Later a simplified version (b2), of lower power (.12w), was used by the Panzergrenadiers.[3]. 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). Range up to 100km. $79.99 A common infantry set. I have a Book Scanner that can do bound books. .15 Watt output AM voice and CW. A technician who modifies or hacks a radio to transmit on frequencies beyond its usual design parameters. Number ranges were not unique across the services so sometimes different equipment used by different services had the same FuG prefix. It was matched with transceiver Fug 16 for use with Sturmartillerie (self-propelled artillery). Its just too bad that theres not as much to listen to in HF these days, unless one jumps into amateur radio. << /S /GoTo /D (subsection.6.1) >> (on the work youve done and the article) Thereafter version b1 was used by the Pioneers. This office would be responsible for coordinating all of the purchasing and shipping of supplies (Woodbury, 1946:68). The later was tricky, with some high, medium, and low-band-specific alignments required. In fact, using sound to psychologically attack an enemy has roots in the ancient Aztec culture. 80 0 obj ( Critical frequency, LUF/MUF, Hops e Multipath) Some radios are pre-programmed to repeater channel frequencies, and some will need to be . 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. Fug 1: Also known as Torn.E.b And Pack Receiver b. I connected up my 20 m external dipole and powered up the radio.

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. Something was not right with it, the plates on the large variable tuning cap were literally grinding against each other. When we were young; in the 70s; we destroyed literally tons of stuff like that just for fun. If run out of trim, I might do a little naughty and just strap a little booster cap across it. Low as 50v on the plates but diminished audio I measured <1 uV on AM at 2 MHz, more than good enough for me and easily exceeding the original factory spec. Power 220 V AC 50Hz 680 VA. Stuttgart - FuG D 3: Development item, possible none deployed. endobj Im surprised. It is a criminal offensive to hike the Stairs, and you could be fined a minimum of $1000 if you are caught. But American pilots still avoided dog fighting and utilized the dominant characteristics of the Hellcat to inflict heavy losses. The Hellcat was superior to the Zero in every way except in a slow turn. It operated in the 24.1 to 25MHz (24100 to 25000kHz) frequency range with a transmission power of 5 Watts. Particularly the higher valued ones in the 100s of K or M ohm range. Power output: 40 to 70 watts on CW and 10 to 17.5 Watts on speech or MCW I had about 25+ years ago picked up this old WW2 4 cyl generator a PU-35/U , remember it had about 8 hours on the hour meter, it might have about 9 when I got it I fired it up, had it outside in a box, would like to get rid of it if anyone would be interested, can send some pictures. I got good use of a BC-455, the one that covers 6.0 to 9.1 Mc. 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. Olek has updated the project titled Fan Controller. That radio has an acceptance stencil from Alameda Naval Air Station The "Backpack" or Torn series and the field or Feld series. Range was approx 23km when using AM voice and 34km when using CW. Torn.Fu.a: A HF transceiver. Axis Sally (Mildred Gillars) Several American Nazi sympathizers worked as broadcasters for German state radio, but perhaps none was as famous as Mildred Gillars.

I have a couple stock R-2x series receivers (navy version) and BC series (Army version). endobj A capacitor must operate to its specified value so it is good to test to see if the cap is functioning as a cap. Known for being one of the first hand-held models, over 130,000 SCR-536 units were used to help conduct many important missions, including the famous invasion of Omaha Beach in Normandy. 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. It was used with a frame antenna on various reconnaissance units. I built capacitor packs that fit in the space and attached to the chassis with a solder lug. M. Bindhammer has updated the log for Enhancer mask. 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. Was present in almost all German tanks and some other vehicles. Now that everything was in order it was time to try the radio in its final configuration. Air Traffic Control (Towers and ARTCC's) 121.3 MHz. Receivers use a single-conversion heterodyne architecture similar to that of big wood console radios of the era. This thing was preserved as good as the day it was removed from its F4F Hellcat. Next I checked all of the resistors with my Fluke DVM. It was used by the observers to communicate with the armoured unit leaders via their Fug 5 radios. My grandmother was a ham during WW2, my grandfather was in the signal corps. Electronic warfare receivers to detect enemy radar signals. If one fails and the failure results in burning up some much harder to replace part was it worth it? 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? << /S /GoTo /D (subsection.5.2) >> The frequency range was (Mc) 20 to 27.9. 21 0 obj First order of business was to accurately test the capacitors because it was obvious that some were not functioning to spec.

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. 3. endobj 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. 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. It was used for communication back to the regimental command post. It was usually used with a 1.4 metre antenna. Depends on the service. It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 30 Watts. Could interwork with the Fug 5 of the armour. Naturally their foray into military-technology innovation affects the way defense satellites are designed in the next half-century. In 1923, the first transatlantic contact between amateurs in England and Connecticut occurred, opening up the world to long-distance communications. It was used on most of the larger aircraft in the war. I bought it from a fellow in a wheel chair who had a shed full of surplus electronics. 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. Today surplus stores only have contemporary Chinese-made boots, camping gear, and flashlights. There I found a unicorn of historical significance; an un-modified-since-WW2 surplus CBY-46104 receiver with dynamotor. During this hearing Admiral Moreell laid out the exact method that would be used in building the bases. 81 0 obj 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. DMG 2 T: Pack unit, operating on the 475 - 525MHz band, single channel voice or 800 character-per-second teletype. Excellent project. endobj endobj 0.7 Watt output AM voice and CW.
