Military Collector Group Post, No.14/97 Index; Basic Collection of Japanese Radios, Part VII Bill J. Needs a Hickok; HUMOR; *********************************************** Basic Collection of Japanese Radios, Part VII ed) I don't know if this part of the series has been posted yet or not as the Group Post have not as yet all been recovered for Nov.7-10. So here it is, maybe for the second time. If you have already read this part, please send me backthe group post it was contained in. Thanks, Dennis WW II JAPANESE TYPE 94 - 3 A WIRELESS STATION By: LTC William L. Howard A reasonably rare Japanese Wireless set is the Type 94 - 3 A Wireless Station. There are three known examples in the United States and one in England. While there may be others, they have not surfaced. I was fortunate to obtain a complete set, in the transport case as well as an accessory chest. Of the known sets, mine is probably the most complete. Several of the WW II Japanese sets became the subject of Technical Bulletins designed to show the American troops how to use the set if captured. Unfortunately the Type 94-3 A set was not one of them so there is very little known about this set. The set was first written about in the WW II TM 11-227 A on Japanese Radios. This was a cursory description, designed more as an identification guide than a technical study. It is officially designated as the Type 94 - 3 A Wireless set, Mark 36 Transmitter, Mark 36 Receiver and another set is identified as having a Mark 36 Type D Transmitter and a Mark 36 Type D Receiver. The Data Plate also has the designation SP 3 in English and the set is sometimes called the SP 3. The Type 94-3 A set with the Mark 36 Transmitter and Receiver is listed as CW only. The set with the Mark 36 D Transmitter and receiver is listed as Voice and CW. The set is transportable by pack animal, being loaded on two pack horses or on a Class C transport wagon. The set, at wars end came in three transport chests, although the Army TM indicates two chests.. Chest No2, which I have never actually seen, must be the chest shown in TM -E-30-480" Handbook on Japanese Military Forces@ and contained the Model 29 E hand cranked generator, power cables, a pull out drawer which contained the transmitter coils, a compartment with spare tubes and a compartment which probably contained headsets and keys as well as antenna wires.. Chest No 1, which is shown in the photograph housed the transmitter, the receiver and the receiver battery box on the left side. On the right side was a drawer which when pulled out revealed three compartments. Four of the receiver coils were stored in two green felt padded spaces. The center compartment contained other accessories. Above the drawer was a small area which was probably used to store the technical manual and possibly message pads. Above this space was a compartment with a removable front panel. The set shown in the book, APearl Harbor and the War in the Pacific@ shows spare tubes in this compartment. The inventory chart inside the chest cover was for the No. 2 chest so it was of no help in identifying what was supposed to be in there. The compartment was probably designed to hold the key, and the headset. It may have housed the remote control unit for remote keying. The Army TM on Japanese Communication Equipment shows a small chest housing the four transmitter coils, with an empty center compartment. This small chest was the drawer from Chest No. 2. The contents list for Chest No 2 indicates four coils which were the transmitter coils. Chest number 3 which is designated as the Accessory Chest, It has an open space at the top and three drawers which pull out. The bottom right drawer was designed to hold spare batteries for the receiver and for the flashlight. The center drawer was for a variety of small parts such as resistors, capacitors and screws as well as oil can, cleaning cloths , spare bulbs and neon indicator bulbs. The drawer on the left was to hold solder, wire, friction tape and hemp yarn. The open upper compartment was to hold a No 7 repair kit, more batteries, a Type 92 flashlight, although this is not confirmed and more receiver filament batteries. It also held an item that was translated by Mr. Takashi Doi as ACANDOL@ which I originally assumed was a holder for a candle or perhaps an alcohol burner used to heat the soldering iron in the tool kit. Later information was that a blow torch was used to heat the soldering iron. The candle container was most probably the leather case that contained a candle lamp that was collapsible. The tool kit held a soldering iron, a screwdriver, a pair of tweezers, a pair of pliers and a combination wrench set of three wrenches joined at the center. I was able to come up with this repair kit but it was missing the screwdriver The soldering iron cleaned up nicely but the other tools were so badly pitted that I had them re-chromed.. In addition to the items in the chest, the inventory list also had a note that the antenna pole sections were to be in a canvas case fastened to the chest. The antenna was a flexible, single strand wire, 66 feet long, light yellow in color suspended between two jointed poles of alloy pipe that were 23 feet high. There must have been 16 of these poles. In addition, there were also two ground wires, a black one 33 feet long and a brown one 66 feet long. The radio proper is housed in a metal case inside the No 1 transport chest. The front cover has three catches which must be released to allow removal of the cover. Inside the cover are the schematic diagrams protected by an isenglass cover. There are also two calibration charts which can be removed, from the metal frame holder. The radio set with the Mark 36 Transmitter and receiver is a 15 watt transmitter capable of CW used for medium range communication. The Army TM states that it is ideally suited for guerilla warfare, since it can be used for months without replacements or battery charging. Chromium plated surfaces make it suitable for use in the tropics. It was used between divisions and regiments. The No 3 platoon of the Division signal company was issued ten of these sets. Each section consisted of one NCO and 6 men. These sections were then dispatched to the various regiments and division troops as needed. In the same fashion, the regimental signal company sent sections down to the battalions and to regimental gun battalions. It uses a UZ 510 B tube in the transmitter which can be replaced by a US 807. The transmitter requires 500 volts for the plate supply and 7 volts for the filament supply . This is provided by a hand cranked generator. The army TM shows a power cable with a solid plug that plugs into a socket. The actual power connection strip is capable of accepting both a plug and a cable with spade lugs. This may have been done so the set could be powered by both the hand cranked generator and a power supply run from an AC line. One would assume that a division headquarters would have a large generator producing AC to operate all the devices that would have been there. The transmitter covers 0.4 MC to 5.7 MC. There are 5 transmitter coils, 1 through 4 are simple plug in coils. Number 5 coil has a switch marked 1 or 2. Four coils stored in a chest and the fifth was plugged in to the set. The transmitter has a built in key and provision for connecting an external key, as well as connecting to a remote control. Keying is in the negative high voltage lead, which with 500 volts can lead to a nasty shock if using the front panel key. The transmitter is crystal controlled and by removing the crystal, the master oscillator is connected and tuning is accomplished manually. To the best of my knowledge, no examples of the remote control box exist. The schematic diagram shows a patch cord with plugs on both ends. I have the patch cord but not the remote control. Maybe some day a sample of this device will surface. The receiver is a five tube six stage superheterodyne. Rf circuits are trimmed by adjusting circuit inductances and capacitance. Inductances can be reached from the top when the set is removed from the case. The detector has a Rheinartz type regeneration controlled from the front panel. The receiver covers 0.35 MC to 6.0 MC and is capable of voice and CW reception. The receiver is powered by four Mark 18 B dry cells, 22.5 volts each and One Mark 3 square model dry cell for the filaments and a Mark 129 C cell for bias supply. The batteries are kept in a drawer at the bottom of the set and wired to a socket that mates with a plug on the back wall of the case. The battery compartment has a cover, probably fibre board with a wiring diagram for the batteries, which was missing from the set which I obtained. In this article I have given only superficial coverage to the transmitter and receiver because Ken Lakin has one of these sets, has it operational and is writing a more detailed article on the set, its circuitry and its performance. Since he is better qualified to discuss the electronics than I am, I leave the readers to await his article. As a collectors item this set is very desirable and scarce. This set had serial number 3524 The date of manufacture in Japanese is shown as 2 1 and 6 1, which means the set was made in December 1941. Ken Lakin has the set with the transmitter serial number 3984 which was made in October of 1937. so it can be inferred that there must have been at least 3984 sets made prior to 1938. This however is doubtful as these sets were issued on the basis of 10 per Division Signal company. I suspect that it is more likely that serial number blocks were assigned to an assembly point and they used them as they put these sets together. In the No. 1 transport chest and with the No 2 Chest and the No 3 Accessory Chest this is a very rare set. I have hopes that some day the No 2 chest will turn up, maybe even with a generator! And maybe I will find the correct front cover for the NO. 1 Chest! In the meantime, I am looking for a Number 3 receiver coil and the Number 3 and 4 transmitter coils. If anyone has additional information on the set and would like to share it, contact me by mail or e-mail at wlhoward@gte.net . Japanese Type 94 - 3 A Wireless Set, Contents of Chest No 1 This chest housed the Transmitter, receiver, battery drawer and the receiver coils. I have the set in the chest but somewhere the covers of the No 1 and No 2 chests were switched.. The following accessories have not been listed in some other chest so it can be assumed that they were kept in this chest. They include: Key for transmitter ( Chest No 1) Remote cable to connect transmitter to remote control box Antenna wire 66? yellow, rubber covered wire ( Chest No 1). Headset with cable, possibly 1 set.(Believe one set was in Chest No 2) Remote Control Box(Model, make, etc unknown) There is a remote control box for this set that consist as a minimum a battery, a jack for the plug and line terminals. This could have been made small enough to be stored in the top open compartment. Thus far, this item has never been seen or photographed so do not have any information on it. I received a letter from Mr. Takashi Doi, who has been in contact with a former member of the Japanese Army who used this set in China. The old soldier said he only used the remote control unit, once in China on a large military exercise. For the most part, the remote unit was used with larger high power ground transmitters. In another letter discussing the candle, the old soldier said they never used the lamp as it was hard to clean. They just stuck the candle on a small plate or even stuck it on the radio set! Typical of a soldier, not going to make any extra work for himself. Japanese Type 94-3 A Wireless Station Accessory Chest No 2 contents Contents of the No 2 Chest of the Type 94-3 A Wireless Station This is based upon a translation of the contents list inside the front cover It is also based upon an examination of several pictures. The chest appears to be the same size as the No 1 Chest which contains the receiver, transmitter, battery box and receiver coils. The approximate dimensions are 24 ? wide, 20 ? high and 8 ? deep. (The front cover of the No 2 chest fits the No. 1 Chest so they must both be the same size. The chest is divided into two halfs. Presumably each is about 11 ? wide. The right side is open. At the bottom the Type 29 E hand cranked generator is stored. In the upper compartment spare tubes were shown in a picture. Japanese tube boxes are 2 1/4 inches square on the end and there were three rows. The compartment must have been at least 7 inches high. The compartment for the generator must have been 12 ? high, as the generator dimensions are given as 9 by 5 by 10 ins.. The compartment on the left had three sections. The top section was a pull out drawer and I assume the others were also pull out drawers. The top drawer was used to store the four transmitter coils that were not in use.There were two coils on each side in their own compartment. The coils are 2 1/2 ? in diameter and are 3 1/2 ? high when stored. By default the center section was 7 ? wide and was divided into two smaller compartments. The drawer then must have been 6? to 8? deep. 11 + ? wide and 3 1/2 ? high. The remaining two drawers then would have been 16 ? high or 8? high per drawer. Accessories that were listed on the contents list Transmitter Coils (4) Headset with cable, possibly 2 sets. Transmitter crystals ( Two Type 3 stored in the drawer with transmitter coils) Voltage Meter Chart Sling (For the radio set) Connection Codes for Test Type 3 Antenna Retriever, Rope (2) Generator Accessory Bag, with Power cable and sling Antenna Retrievers ( 2 ) Type 3 -B Wooden reels(Like a kite or fishing line with the Counterpoise wires of 33 ? and 66 ? black and brown Type 2 B Spare Antenna Wire---Inverted L use-- Generator, Model Number Type 29 E (With 2 hand cranks and 1 small bulb) Japanese Type 94-3A Wireless Station Accessory Chest No 3 contents. Translated by: T. Doi The chest has three drawers and an open upper space divided in to two compartments.

Type 92 Battery powered light (Some form of flashlight)(Not confirmed ) Item translated as ?Candle container? ( Have found a candle container that is part of the candle lamp, so assume the candle lamp?s leather container which housed a collapsible lamp and two spare candle containers must be what is referred to as Candle container ) The bottom left drawer contained the following items: 100 grams of solder 30 meters of rubber covered insulated wire 2 rolls of rubber cotton tape ( assume it is electrical tape) 1 roll of Cotton tape (This is a fabric tape used to repair book covers, etc.) 20 grams of 1 mm Hemp yarn The right side upper drawer contained the following items: 1 brush 1 Lube oil (Assume this is the Generator Maintenance Kit with an oil can & Brushes) 2 small blubs (Assume for the Type 92 Flashlight but could be for the generator) 2 cloths (probably for cleaning) 2 neon tubes (Replacement for tuning indicator in transmitter) Assorted screws in the following sizes 2.6 mm x 15mm 3mm x 15 mm 4mm x 18mm 4 ??? 10 2.6mm x 3mm ?

Then he decided to write a letter to the Lord requesting the $100. When the postal authorities received the letter addressed to the Lord, USA, they decided to send it to President Clinton. The President was so impressed, touched, and amused that he instructed his secretary to send the little boy a $5 bill. President Clinton thought this would appear to be a lot of money to a little boy. The little boy was delighted with the $5 and sat down to write a thank you note to the Lord, which read: Dear Lord, Thank you very much for sending me the money. However, I noticed that for some reason you had to send it through Washington, DC and as usual, those jerks deducted $95.
