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. 33 0 obj She would also listen for my grandfather just to be able to hear his voice. To check for value and leakage with one test device you must resurrect an old piece of test gear known as the capacitor checker. 20 0 obj A capacitor must operate to its specified value so it is good to test to see if the cap is functioning as a cap. I figured out the problem after about five minutes of reverse polarity operation. endobj I hooked up my 20m dipole and to my amazement I was tuning in AM broadcast stations at around 1500 Kc. It was used for by observation teams of the Sturmartillerie to communicate with artillery units. 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. Frequencies from 1-11 GHz are frequency bands where SAR imaging radars operate. Range was line-or-sight so the ranges reported here were assuming the antenna could "see" one another.[4][5]. Used by the infantry at the regimental and battalion level. Most likely Im the odd person put on the topic. Channel 1, voice or 2400 CPS teletype. Radio during WWI At the onset of World War I, radio was still in its infancy. Fug 21: A 0.1 - 10MHz receiver paired with a 2.5 - 7.5MHz transmitter. In the near future the unique and innovative organization of the CPNAB set forth by Admiral Moreell would prove indispensable for expeditious construction in Hawaii after the 1941 bombing of Pearl Harbor (Woodbury, 1946:55). MUF: Maximum Usable Frequency MW: Medium-wave SW: Short-wave VoACAP: Voice of America Coverage Analysis Program 4.2 Overview Radio propagation is the mechanism by which the EM waves (also known as radio waves) are transmitted, or propagated, from a point on the earth to another directly or through various layers of the atmosphere. Fortunately these are easy to service, they are designed so that anyone with a flat-head screwdriver can fix them. 17 0 obj Feldfu b1: Pioniere 90-110Mhz range 1.5km. 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). Old radios are like old cars, they could use an alignment from time to time. Range 5km AM voice.[1]. 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). 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. 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. endobj It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 30 Watts. 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. FuG 5: A high-band HF/low-band VHF transceiver. endobj It was used for communication back to the regimental command post. I think its laudable that he kept the mods and replacements to a minimum. Very impressive! photo right . By accident I even connected the DC input backwards, reverse polarity. [3], Torn.Fu.k: A HF transceiver. John in Texas. Identical to Torn.Fu.b with exception of frequency range. This thing was preserved as good as the day it was removed from its F4F Hellcat. Transmission power 0.15 watt. (LUF \046 MUF) The units of the T series were "backpack"-style mobile equipment. Next I had to locate documentation. FuG 17: Designation for a Torn Fu H transceiver. The time station is WWV on 2.5 MHz exactly. If small amounts of current (on the order of single-digit uA) leak through then that capacitor is bad. qk|UbVE4k%3DsRaEAYsombT_FG46m,@0E/N7U.

Fug 18: Group of radios covering 25 - 77.1 Mhz Fug 19: A transceiver operating in the range 3 - 7.5 Mhz. endobj I wonder if the Nazi's used Hertz? In fact, using sound to psychologically attack an enemy has roots in the ancient Aztec culture. 1. It was matched with transceiver Fug 16 for use with Sturmartillerie (self-propelled artillery). It was used by the observers to communicate with the armoured unit leaders via their Fug 5 radios. The Role of Radio in Wartime France. It was used with a frame antenna on various reconnaissance units. 5 0 obj The dynamotor roared into life but the radio never produced audio. 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. FWIW according to the Tarrant ORB , 116.1mhz was the guard freq worldwide in 1946(That was DSB-AM- Amplitude Modulation). In an effort to take some of the fight to the enemy Winston . Torn.Fu.c: A HF transceiver. How to make this low frequency radio system become reality was one of the most complicated jobs in the Pacific during the war. I was a bit surprised at how the caps actually tested. 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). Torn.Fu.d2: A VHF transceiver. the vital issue of using private contractors to do the work in the pacific. Power output: 40 to 70 watts on CW and 10 to 17.5 Watts on speech or MCW endobj This office would be responsible for coordinating all of the purchasing and shipping of supplies (Woodbury, 1946:68). Leakage testing is absolutely critical and must be done for each and every cap. In 1920 a receiver station was constructed at Wailupe. 80 0 obj It was used for by reconnaissance elements for intercommunication. (Tactical Information \(non-coded\)) It was used with various antenna ranging from 1.8 to 9-metre antenna. Dynamotors are motor-generators; in my case one end is a spinning motor at 28VDC motor and the other end is a 250VDC generator. Stephen Chasey liked LIDL PARKSIDE Battery hacks. endobj Feldfu c: 130 - 160MHz infantry. This site uses Akismet to reduce spam. And at the other end, the magnetron was developed allowing high power microwaves, mostly for radar.

A true restoration, not a replace old carcass with modern guts restoration like weve been so used to seeing. Channel 1, one voice channel or one 800 CPS teletype. The electrolyics, however, were extremely leaky and did not reform. A cable linked the two men together. The Navys radio station installations grew rapidly. Used by anti-tank units. >> (BBC Radio Signal Prediction) As an aside, this included radio-controlled tanks. 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. (Fug 8 + Fug 4). Theres no getting around this, otherwise you might miss-read the cap value or leakage test. Its tedious, but even photographing each page with a digital camera is better than nothing. Which Gen Set Manual do you have? At Midway Wildcats, like Devastators, took very heavy losses. In modern low-voltage electronics the key metric to capacitor goodness is ESR. endobj One more item was needed to give the Pacific fleet full striking power: absolute certain means of radio communications with headquarters at Pearl. Great write up. 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 tweaked the antenna coupling control, they were louder still. endobj Eric Steven Raymond (Multipath) Consisting of an RFID reader and transponder, RFID systems can include multiple tags (antennae paired with a microchip) that can send out . One of them went under the stairs and there was the characteristic sound of a dynamotor spinning up they blasted out Morse at (I think they said) 2kW for a few seconds and then G4EYL used her best local-radio announcers voice to tell them they werent welcome. Erythrocyte Sedimentation Rate. When we were young; in the 70s; we destroyed literally tons of stuff like that just for fun.

It was used with the same antenna as the Fug 8. Please note: the Haik Stairs are currently closed and illegal to access. Rule 3. is generally totally incompatible with rule 1. Of course, they called them megacycles, rather than MHz. I just helped a friend get one working last week. (Introduction) First order of business was to accurately test the capacitors because it was obvious that some were not functioning to spec. Feldfu b2: Panzergrenadier only two tubes, no AF tube Rv2,4P700. 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. FuG 14: Multi-radio setup consisting of several separate radios. Free shipping for many products! By the end of the war, the Hellcat had a 19:1 kill ratio over Japanese aircraft. The frequency range was (Mc) 20 to 27.9. As long as they dont affect my person, family, friends, or our property, I dont care what others do with their property. 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. I can confirm 30ish mhz, as I used them in training. Sound torture is nothing new. Channel 1 control channel voice, Channel 2 nine voice channels or p x 3 Teletype. Remarkably enough, the vast majority of these Feb 1942 capacitors tested good. Feldfu d: 32 - 38MHz Artillery Observers. Range 1.5km. At the time it was considered one of the largest radio receivers in the world and could receive six messages simultaneously. Given the changes to the tuning unit I realized that I had to do a full alignment. 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. Feldfu b: 90-110MHz Used by the infantry used in two versions. I put them back into place and the tuning unit was good as new. Army equipment was primitive, had a very short range, and often negotiated atmospheric interference. endobj have extremely high DC impedance) at high voltages. There are plenty. 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. Nice! During the war this was extended to cover the majority of the occupied areas or Europe and North Africa. The later was tricky, with some high, medium, and low-band-specific alignments required. 1940-1949 IT'S THE OLD STORY: A glamorous movie actress and a brash avant-garde composer get together to invent and patent a device that controls torpedoes by radio. Electromagnetic radiation falls . This mine was first developed in 1929 (90 years ago!) I opted to re-stuff the defective caps by opening the metal cans, extracting the guts, and putting in a modern replacement, then gluing the cans back together. /Length 783 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.

They are bitterly disappointing except for one surplus store that I found while on vacation in the Adirondacks: Patriot of Lake George. Torn.Fu.h: A HF transceiver. ESR is Equivalent Series Resistance and NOT Electrostatic Resistance as you said. For example In regards to this topic any service manual or schematics, hopefully that have been hopefully digitized along the way. Dynamotor worked perfectly, just like new again! The wireless was invented by Marconi in the late nineteenth century and the Navy was quick to make use of the new technology. Isnt ESR short for Equivalent Series Resistance? Range 10km AM voice to 40km CW. Radio was the cheapest form of entertainment, and it was the most popular medium during World War II. Occasionally the shorted Fu designation were used and there were exceptions to both these systems. One of the forerunners for this technology was the revolutionary electrical musical instrument developed by Leon Theremin.

Hung-Yu David Yang, in The Electrical Engineering Handbook, 2005. 48 0 obj Im also in agreement to not drill holes or modify per the surplus conversion handbooks The British broadcaster is turning to frequencies that still work during a communications blackout. How the lineage of the walkie-talkie reaches from World War II to the modern cell phone. Imagine the stories it could tell! This would be the first time that the Government had ever used this method on a big job (Woodbury, 1946: 52). Both the army and the air force made use of the same equipment. Great project! Power 22 V AC 50Hz 300 VA. Rudolf - DMG 3 G: 'Heavy' link. In 1923, the first transatlantic contact between amateurs in England and Connecticut occurred, opening up the world to long-distance communications. A life on the line - SOE radio operators in the Second World War. Used at the regimental command post. .15 Watt output AM voice and CW. Early in 1945, in the Northern Appenine mountains of Italy, T/5 Harvey, a radioman with the 10th Mountain Division, is carrying his WW2 . To check each cap I had to remove each of them from circuit, one at a time. Create an account to follow your favorite communities and start taking part in conversations. 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 communication on these frequencies was by either hand keyed Morse code or radio teletype. (Even if it was just the dial lights in some!). In my experience, the dynamotors were often the first thing to be discarded on those sets. Depending on the set a range of communication facilities were available consisting of voice and/or teletype and Hellscriber. Operating on the 502 - 555MHz band, two channels. Join the movement, there are many others who restore WW2 and other vintage gear to be original as possible. Could interwork with the Fug 5 of the armour. Was the standard kit for tank-to-tank communication within platoons and companies. It led to my career in electronics. << /S /GoTo /D (subsection.4.4) >> (Looking at you, [MisterM]!). Besides if you really want the original experience.. it didnt have 70 year old caps in it 70 years ago! The contractors did not reach any definitive conclusions but very quickly the prospects of a radio station in Haik Valley took on a demanding nature and immediate decisions began to be made about the construction as the plans for the Pacific Naval Air Bases took on an offensive position. I was one of the youngsters who got an ARC-5 receiver in the mid 50s. It operated in the 2.5-3.5MHz frequency range. Some command and reconnaissance units had this infantry transceiver to allow then to talk to Panzergrenadier units.[2]. The Hellcat was of course better but that is only to be expected. 73, gary/NJ8BB. End of problem. This unit was also used by motorcycle troops in the first half of the war. Generally speaking much lower than common use bands today. 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. The PNAB was initiated in the 1930s as turmoil was mounting in the Pacific. Range up to 50km. Long-distance ham radio communications began in the 1920s. The audio amp tube socket is a problem. Not reversible. These were usually early-model tanks with some of their armament removed and replaced by equipment for artillery observers. 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. After the war the codes were declassified and Ka band and millimeter (mm) were added. Then noise came out of the speaker. 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). The date of manufacture was early-war, February 1942. L.I.N.Y. I love seeing the WWII equipment properly restored. and deployed operationally in 1941 in the "Great Patriotic . It operated in the 23,000 to 24,950kHz (23-24.95MHz) frequency range with a transmission power of 10 Watts. I never played with the transmitters very much. The receiver was not too sensitive, and tuning was jammed up at the higher frequency ranges on the dial. It operated in the 1.5-2.6MHz frequency range. In has been reported that the 7055 kHz LSB amateur radio frequency has been used by Ukrainian and Russian amateur radio operators for some time now to insult each other in a 'radio war', and recently activity has significantly increased. Range 25km AM voice to 140km CW using the nine-metre antenna, the station had to be stopped to use this antenna. /Filter /FlateDecode 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. Most places cant scan books without destroying the original unless you pay a fortune. 53 0 obj Finally someone restoring something instead of shoving in a raspberry pi. 12 0 obj It operated in the 1,130 to 3,000kHz frequency range with a transmission power of 100 Watts.

It was used with antenna of either 1.4 to 2.0 metres antenna. Not intended to be used on the move. The SCR-536 was a two-way, portable radio used extensively by United States armed forces during World War II. Testing capacitors with a DVM in resistance mode will show which are short-circuited but it will not reveal the leaking capacitors that are only leaking ever so slightly (e.g. I removed the bells (end caps) from both sides of the motor. ( Introduction) If run out of trim, I might do a little naughty and just strap a little booster cap across it. I tested the electrolytic and paper caps with a Fluke DVM in resistance mode for obvious shorts or low impedance. magopeter liked Water Meter Monitor with Raspberry Pi Pico W. itproducties.nl liked Global radiation monitoring network. 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. I left the original rear power plug in place and found out that miniature banana plugs fit perfectly into the WW2 socketed pins. Range 1.5km. That increased both the gain and the selectivity of the radio. of the 348) that my Dad used in the late 40s. Actually, the 3D printing would solve a nasty problem in making WW2 gear operate again; finding the connectors! FuG 8: A medium-wave transceiver (receiver/transmitter) used in command tanks. I even used the receiver as a tunable IF in a science fair project experimenting with mixers/converter for 10mhz WWV. To preserve this historic treasure my rules of restoration were: These were not easy rules to follow because, as we know, the first step to antique radio restoration is to replace all of the paper and electrolytic capacitors, saving a lot of headache and time. The instrument could be . England. are control channel capable frequencies RFSS Site Name County Freqs; 1 (1) 001 (1) Baltimore Simulcast: Baltimore: 769.18125: 769.45625: 769.48125 : 769.71875: 770.23125: 770. . It was usually used with a 1.4 metre antenna. Flavio Moreira has added a new log for Radio Feather X. Keri Szafir liked Resurrecting Old Computer Hardware And Software. Admittedly, OCR isnt going to be useful for photos, diagrams, and symbols, but in most cases even raw camera images will be far more useful than not having the data at all. Next I checked all of the resistors with my Fluke DVM. Along with the previously erected Naval station at Lualualei Valley was a naval communications station at Wahiawa, near Schofield Barracks. (Critical frequency) They used radio frequencies from 15 kHz to 33,3 kHz. (Episodes of Nazi-fascist violence) Nice restoration. 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. Big dynamotors explode in total awesomeness if you apply mains voltage to them. It drives me nuts to see someone take something that should be in a museum and butcher it. It was usually used with a two-metre antenna. Will have to replace it. 28 0 obj It was used with antenna of either 1.4 to 2.0 metres antenna. endobj Very nice rebuild, a lot of patience to test each capacitor multiple ways. Like weather frequencies, the Ham net frequencies also vary from state to state. As much as Ive read about Dynamotors, Ive never seen on in action. 60 0 obj Range up to 50km.

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. Most of the community orbits around Electric Radio Magazine. Radio Saigon was designated to carry anti-British broadcasts to India, backed up by similar programs emanating from transmitters in Singapore and Bangkok. Another system, and the subject of this blog piece, was the F-10 radio-controlled mine. 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. Macona: The one-way voice link (OWVL) described a covert communications system that transmitted messages to an agent's unmodified shortwave radio using the high-frequency shortwave bands between 3 and 30 . This equipment provided for 125 radio channels at 50kHz channel spacing. Olek has updated the project titled RelAC - Relay module for smart home appliances. It was used with a two-metre antenna. The radio could have been used in both. Single-unit "walkie-talkie" system. One of the first tasks was building the Operation Office in Alameda.
