VOLUME SEVENTEEN - NUMBER THREE
May 17th 1998
Hello DXers and Radio Friends.
Last week we said we were goung to test the KIWI Transmitter with a five
minute voice test at 08.00 UTC on 7475 KHz USB.
It should heve read That the test was for the 16th of May, Not the 10th.
Please accept our opologies, and hopefully things will go alright this
time.
These tests were good, with reports from Australia "Recieved Loud &
Clear", so we may hear from the USA ??
Due to this mix up we WILL DO another 5 minute ( approx ) voice test on
7475 KHz USB at 08.00 UTC on Saturday May 23rd 1998.
Our Legal operation SOUNDWAVE FM has a new Show hosted by
Ian Brown of Whakatane's 1XX Radio, called "REMEMBER WHEN"
For more info please look at:

LA NUEVA RADIO MUSICALE:
Congresswoman Rosa DeLauro (D-New Haven) is standing up for the FCC in
the ongoing fight over unlicensed "La Nueva Radio Musicale."
In an op-ed piece in the New Haven Register this week, DeLauro said she
understands the need for a station like the 104.5 pirate, but she says
the FCC's duty to keep the spectrum well-policed for legal stations
takes priority. The 104.5 folks (who are back on the air after a
third FCC visit last week) had presented DeLauro with a petition
supporting their cause.

JAPANESE HRO TYPE RADIO RECEIVERS;
By: LTC William L. Howard
[ originally published in: MILITARY COLLECTOR GROUP POST, May
9/98 ]
In 1934 the National Company came out with a new radio designated as
the HRO, supposedly for "Hurried Rush Order".
This set was a 9 tube superhetrodyne set that used plug-in coils in the
front panel, and an unusual four gang tuning condensor that was mounted
at right angles to the worm gear attached to the tuning control. The
tuning dial also had windows that revealed dial graduations.
This set was copied by many nations, if not directly, then in a similar
style, plug-in rectangular coils, four gang tuning condensor.
Figure 1 Schematic of Type HRO receiver.
By the late 1930s the Japanese realized that new radios were
needed and by 1943 these sets began to appear in the field. For the
most part, Aircraft radios began to be made using octal base tubes.
Examples include a radio direction finder that was copied from a pre-war
Bendix Aviation set.
Other aircraft radios began to use octal base tubes.
The first of the Japanese HRO sets was an exact copy of the HRO
with some minor changes. Once the factories were tooled to produce
parts for this set, it would appear that radio engineers were instructed
to design furure radios making use of the components that were made for
the HRO. Principaly these were the plug in coil forms and the four gang
tuning condensor.
The first set of the HRO copies was designated as the Mark 1 Ground
Wireless Receiver. It came in a large wooden chest that housed the
receiver, a power supply, two drawers of plug-in coils and a drawer of
accessories. These accessories included the headphones and another set
of IF transformers as well as other items. The power supply contained
two switches and a meter.
This set was followed by a Mark 2 Wireless Ground receiver. I
have not seen any of these so am unable to comment in detail on this
set. This set seems to have been issued with a companion transmitter. It
used eight tubes, a UZ6D6, a Ut 6l7G,another UZ6D6, two UY 76s,two
Ut6B7/2 and a UZ 41 as the final audio amplifier. This set seems to have
followed the schematic of the HRO but with out the amplifier tube for a
speaker.
Figure 2 Block Diagram of Mark 2 Wireless Set Receiver.
The Type 99 series of aircraft radios had progressed from the
Mark 1 to the Mark 4. The Mark 5 series had a receiver that appears to
have been strongly influenced by the HRO design. This set made use of
five tubes while the National HRO had 9 tubes. A 6F7 and four UZ 78s
were mounted behind the ganged tuning condensor, and behind the row of
tubes were the interstage transformers. Since the aircraft did not need
a speaker, the last tube in the HRO schematic could easily be
eliminated. Other modifications could have been the elimination of one
of the IF stages and possibly one stage of RF amplification, although
the four gang condensor would indicate two stages of RF amplification.
The next set in the HRO series that I have encountered was called
the Mark 3 Ground Receiver. Little information on this set exists.
Someone sent me a polaroid photo of this set. By checking in a post war
Japanese book on radios, it was identified as the Mark 3 Ground set. It
appears to have been developed by the same group that developed the Type
99 Mark 5 receiver. The set was mounted in a metal case that had two
elements below the receiver. What these were is not certain but was
probably the power supply. It appears to have been the same power supply
as used in the Mark 1 set but without the meter. By 1943 the Germans had
begun to eliminate meters from their sets as parts were in short supply
and it can be assumed that the Japanese experience was similar. Meters
were needed for transmitter and not for power supplies.
The Mark 3 set used the four gang tuning capacitor and a plug in coil.
It however used only five tubes. A UZ 6D6, a Ut 6A7, and three more
tubes, UZ 78 or UZ 6D6 which appear to have been interchangeable.
Figure 3 Block Diagram of Mark 3 Wireless Receiver.
There was also a companion transmitter with this set. It had
three meters across the top, three vernier tuning dials, a plug in
crystal socket and other controls. This transmitter appears to have been
a four tube transmitter. The Japanese text refers to an 807A so it is
assumed that all the tubes were 807As. Probably some sort of MOPA
circuit. I have never seen one of these transmitters so the information
is limited.
The Mark 3 Wireless set set seems to have been superceded by a
new ground radio designated WIRELESS STATION MARK 4 GROUND.
Exactly what this set was designed for is uncertain, but the data plates
on both the transmitter and the receiver had been stamped with a star
emblem that was usually associated with civilians attached to the army.
It is possible that this set was designed for use by homeland defense
forces. The data plates were made to have the date of manufacture
stamped on them but on the examples
I saw, this date stamping was missing.
This set had a receiver that resembled the HRO. It used a rectangular
plug in coil on the front panel. According to information supplied by
Takashi Doi, there was an early model and a later model of the Mark 3
sets.
In addition a photograph in a post war Japanese book identifies the
receiver and transmitter as the MU 23 set. MU is the Japanese
abbreviation for MUSEN which means radio or wireless. Photographs on the
next few pages show the Mark 3 and Mark 4 sets.
The Mark 4 set probably was closer to the National HRO as it had
9 tubes, however the tuning capacitor only had three gangs and the coil
box had three coil units. The IF transformer was mounted in a plug-in
container so it is assumed that the requirement to change IF
transformers when switching bands still existed. It can be assumed that
there was also an accessory container for this set which housed the
other coils, headphones, keys, cables etc. This set used UZ 6D6 tubes
throughout.
The 6D6 tube is a 6 pin tube with a grid cap. The five tubes mounted
directly behind the tuning capacitor were protected by tube shields,
the
three tubes in the rear and one on the side were not encased in tube
shields.
The example that I saw had three plug-in coils. Coil Number 1
covered 4 MC to 6 MC, Coil Number 2 covered 6 MC to 9 MC and coil Number
3 covered 9 MC to 133 MC, a considerably wider range than the
frequencies marked on the companion transmitter. Controls on the front
panel of course were in Japanese but some one had penciled in BFO,
Volume Control, Main tuning, Wave Tuning, High Cycle, and Antenna
Decrease. Two other items were binding posts for Antenna and Ground
connections.
This receiver was designed to be connected to the companion
transmitter. When removed from the case, there are two power ports, one
four pin and one six pin. When I slid the receiver back into the case,
the four pin
socket was not exposed! It is therefore assumed that the four pin
socket was to provide power when the set was out of the case and being
worked on.
Once back in the case, the set must be connected to the transmitter for
power.
The transmitter also has two power ports, both of which can be seen when
the unit is in the case. The Six pin plug from the power source went to
the transmitter and then a connecting cable transferred power to the
receiver. The power port on the transmitter was marked with a red dot
and the number 1 while the transfer ports on the transmitter and
receiver were marked with a yellow dot and the number 2. While this set
is easy to transport, it takes time to set the staion up and place it in
operation.
The transmitter for the Mark 4 Wireless set is shown on the pages
following the photographs of the receiver. The entire station was
designed to be carried in a canvas pack which is also shown.
The example shown had two packs, presumably one for transmitter and
receiver and one for the power supply and accessories. What sort of
power supply was used with this station is unknown. Presumably a
dynamotor or battery pack and generator were employed although it is
possible that an AC Main line power supply was provided.
As with other Japanese sets, all the parts are numbered and in the
receiver, part number 1 is the antenna connector and the last numbered
part is the headphone socket. In the transmitter, the reverse is
usually the
case with the key being number 1 and the higest number is the antenna
connector. Part numbering facilitates following a schematic during
repairs.
While most tactical ground Japanese sets have a schematic mounted
somewhere in the set, these sets had none.
The HRO copy, Mark 1 set was also powered by a dynamotor. The
dynamotor for use with this set is shown in the pages following the
transmitter and receiver. In addition to the dynamotor, detailed photos
of the power supply are shown. This power supply had provisions for
input voltages as high as 500 Volts.
By late 1943 or early 1944 the Japanese began to use octal tubes
in the HRO sets. The set owned by Ken Lakin had what appeared to be
factory installed octal tube sockets except for the oscillators.
Changing these tubes to octal tubes would have required other major
changes.
Not being able to test these receivers and transmitters limits ones
observations to the manufacturing process and to speculation on the
reason for the design changes. Since the National HRO did not come out
until 1934 it can be assumed that the Japanese did not get any samples
until 1935 or 1936. As the Japanese Empire began to expand, especially
to the far away islands, reliable long range communication was needed
and the HRO was probably the best receiver of the time. Work was begun
to copy the set and once tooling was made, there was a reluctance to
re-tool, hence later versions tended to make use of parts that were
already in production. As the war went on and the Japanese suffered
defeats as well as a shortage of raw materials, manufacturing short-cuts
were taken. This was most apparent in their rifles. Radios, on the
other hand, were not something that readily led to manufacturing short
cuts. The lack of a meter on the Mark 3 set's power supply was not a
major change but rather an economy measure. The transition from a four
gang tuning condensor to a three gang with a resultant shift from four
coils to three coils, probably was a manufacturing short cut. It also
shows that as the empire was collapsing, the range of communication
decreased and perhaps one stage of RF was enough for the Japanese.
Reducing the number of coils needed from the original 9 with the Mark 1
set to 3 coils for the Mark 4 set also reduced the amount of metal
needed.
The receivers turn up now and then but transmitters are rare items and
the dynamotors are extremly scarce items as are the power supplies.
Connecting cables and plugs are virtually non existant. Any effort to
power up these receivers will require fabrication of plugs and cables. A
power supply should also be built, if the original can not be found.
Personally, I would not want to use the original power supply as too
many things can go wrong. U.S. transformers, rectifiers and capacitors
can be used to make a power supply that will work with out taking any
chances on destroying the original power supply.
