Transportkasten FU

Introduction

Radio accessories were often stored and transported in the so called “Transportkasten

Fu” transport cases. These cases were numbers, eg. Fu 1. These numbers are not to be

confused with the equipment set numbers.

To date about 30 different FU transport cases have been identified, there are probably

more but examples or descriptions have not yet been found. For a limited number the

actual content list is known, most need more research.

The first digit of the Fu Nr usually indicates the size of the transport case.

The first two types are suitable for carrying on back; they have connections for

carrying straps and a lumbar support can be fitted:

Fu x: Large case 47,5cm high x 41cm wide x 18 or 20 cm deep

Fu 2x: Medium case 44 cm high x 34cm wide x 20cm deep

All other types lack the connections for straps and lumbar support and are designed to

be hand carried only:

Fu 3x: Medium case 44 cm high x 34cm wide x 20cm deep

Fu 5x: Small case 37cm high x 30cm wide x 15cm deep

Fu 7x: Large case for mule transport 56,5cm high x 35cm wide x 21cm deep

Fu 8x: Large packing crate 68 x 34 x 42 cm

Fu9x: Specialised equipment boxes of various sizes

Four Transportkasten Fu can be recognized (top to

bottom): Fu 1, Fu 2, Fu 6, Fu 5. The markings appear

to be hand painted

Fu 1 (Zubehör)

The “Transportkasten Fu 1” was used

with the 100 W.S. transmitter. It

contained accessories for the 100

W.S.It would by carried in larger

radio vehicles like the Kfz 61.

The Transportkasten Fu 1 contained

items like the microphone, Morse

key, remote keying equipment and

interconnection cables for antenna

and counterpoise.

Figure 4: Transportkasten Fu 1

Figure 5: Transportkasten Fu 1 external

markings

Figure 6: Transportkasten Fu 1 internals

Fu 2 (Vorrat)

The “Transportkasten Fu 2”

contained spares and equipment

for the 100 W.S and

accompanying receiver. It

contained spare valves and

measuring equipment so that

small field repairs could be

undertaken. Some slight

variations of content can be

spotted in the photographs.

The Fu 2 would have been

carried in larger radio vehicles

like the Kfz 61.

From the examples from two

different D-manuals in figures 4

and 5 it can be seen that some

slightly different contents could

apply.

contained spares and extra

materials so that items in

the Fu 5 set could be

replaced and its

possibilities could be

extended. There is no

evidence that any dividers

have ever been fitted to box

so the materials were

packed loosely in the box.

Although typically the

“Transportkasten Fu 6”

would contain antenna

material, some sources state

that the box could also be

used to store an Enigma

coding machine. The

possibility of this option is

demonstrated in figure 15.

Fu 21 (Zubehör S –E) The Transportkasten Fu 21 contained the

accessories of the Fu 9 SE 5 set

comprising of the 5 W.S. and the

Tornister Empfänger. Before 1937 the E

445bs receiver was used in this set, after

1937 the Torn.E.b receiver was used.

The contents of the Fu 21 varied

accordingly. Early versions of the 5

W.S. use a separate dummyload (Kunst

Antenne) K.A.5; on later versions the

dummy load was incorporated in the

transmitter set so the K.A. 5 was no

longer carried in the Fu 21. The box

contained microphone and morse key,

various interconnection cables.

Measuring equipment and spare valves

for the receiver and the transmitter were

carried so that small field repairs could

be done.

Fu 22 (Zubehör E)

No references have

yet been found

describing the exact

use and content of the

“Transportkasten Fu

22”. It contained

accessories for a

receiver, but which

type is unknown. The

partly preserved

interior allows for the

identification of some

components such as a

cable tester but more

information is

required.

The larger compartments to the side could have contained anode batteries or lead acid

batteries, but it is not a perfect fit.

Fu 23 Anodenbatterien

The “Transportkasten Fu 23” contains spare anode batteries a used in portable

receivers. Either seven anode batteries, or a mixture of five anode batteries and 2 lead

acid batteries could be carried.


Fu 24 (Schreibgerät)

The name “Schreibgerät” is a bit misleading, as it suggests some sort of equipment

but the “Gerät” in this case consists of various writing utensils and paperwork.

Several sizes of “Schreibgerät” boxes were available (Fu 24, Fu 52, Fu 83) so that

smaller and larger radio crews could be supplied.

Radio direction

finders have direction

sensitive antennas

which allow the

direction of a received

signal to be

established. The exact

position of the

antenna needs to be

calibrated to the true

north in order to plot

these directions on a

map. Several

direction finders in

different positions are

used to pinpoint the

location of a

transmitter.

The Fu 30 was made by the “Ertel” company, the equipment was also known as the

“Ertel Gerät”. The Fu 30 was later replaced by the smaller Fu 30a. The Fu 30 was

used with the EP2, P57N and other direction finder receivers.

Figure 27: One of the optical instruments of the Fu 30 used to

align the EP2 DF antenna


The Fu 30 contained two optical instruments (one with a compass), cables for lighting

and cleaning equipment.


Fu 30(a) (Richtgerät)

At some point, the

the exception to the

rule that the size of

the box can be

determined from the

first digit of the

number as it is

significantly smaller.

Fu 53 (Eisenportion)

The “Transportkasten Fu 53” demonstrates that not all Fu boxes had to do with radio

equipment, as the “Eisen Portion” contained emergency rations, so called “Iron

Rations”. Interestingly it is one of the few Fu boxes provided with a lock. Emergency

rations could only be consumed on the order of an officer, so the “Funktrupp”

commander probably kept the key to the ration box.



Fu 71 (Vorrat)

The “Transportkasten Fu 71” was

a special box used by the mule

carried version of the “Tornister

Funktrupp d” as used by the

German mountain troops. As

mountain troops tend to face

longer periods of isolation, they

carried extra batteries and

equipment. The picture beside

shows a “Gebirgjäger” leading

his mule. The Torn.Fu.d2

tranceiver and it’s battery box

wre carried on either side of the

packframe, while the

“Transportkasten Fu 71” was

carried on top.

It appears that the “Transportkasten Fu 83” was a larger packing box containing three

“Transportkasten Fu 52” writing utensil sets. These larger boxes were probably

carried in the packing train of the unit so that the individual Fu 52 boxes could be

issüd as required.

Station clocks (Funkeruhren)

Introduction

Correct timekeeping is an essential part of smooth communication. Timing of

transmissions, identification of messages by time stamping, switching of cyphers all

depended on proper synchronization of communication stations.

Figure 64: A selection of station clocks from various manufacturers

In 1934 the Reichheer contracted Junghans based in Schramberg to produce the first

duty clocks for use in radio stations, they are known as “Betreibsuhren”,

“Stationsuhren” or by current collectors as “Funkeruhren”. As the army grew, around

1937 other manufacturers became involved in the production of Funkeruhren:

Kienzle, Tobias Beaurle & Söhne, both based in Schwenningen and Köhler & Co.

based in Laufamholz. Funkeruhren were produced for the Heer, Luftwaffe and

Kriegsmarine. This mix of clients and manufacturers led to the existence of many

different variations of the Funkeruhr.

Basic description of the Funkeruhr

The Funkeruhr is a mechanical timepiece with a 8 day winding mechanism. The clock

has a 6 cm diameter face with centrally placed hour and minute hand. A separate

second hand is placed at the 6 o’clock position, one centimeter from the centre. The

hours are marked in Arabic numerals.

Figure 65: Basic layout of the Funkeruhr face

The clock is placed in a hinged housing which in turn is screwed into a wooden base

measuring 105 x 40 x 130 mm. The clock can be swung out of the housing, revealing

the back of the clock giving access to the winding and time adjustment wheels and in

some cases the speed adjustment.

Figure 66: Clock opened for winding or time adjustment. Various markings can be seen on the

inside casing

The inside of the housing usually contains maker marks, ownership and serial number

of the clock. The wooden base has two metal strips screwed to the underside which

can be swung out to increase the stability of the clock.

Figure 67: The two metal feet that could be extended to add stability

A round metal plate is screwed to the back of the base which allows the clock to be

hung on a screw on a wall.

Figure 68: Metal plate on the back of the clock. The slotted hole allowed the clock to be hung on a

wall

On early clocks the wooden housing was lacqöred in natural colour, at the outbreak of

war the base was often painted grey.

Figure 69: Comparison of an pre-war (l) and late war (r) Junghans Funkeruhr.

Variations by Junghans

Junghans was the earliest manufacturer of the Funkeruhr and produced a number of

variations from 1934 until the end of the war. Junghans produced for the Heer,

Luftwaffe and Kreigsmarine. Early clocks used chromed or nickel plated housing and

metal components while on later clocks the metal was painted grey. Junghans clocks

do not have an accessible speed adjustment, the clock has to be removed from it’s

housing if the speed needs to be adjusted.

The first Junghans example is a 1936 example made for the Luftwaffe. On the face it

is marked “Junghans” as well as “Fl 25591”.

Figure 70: Pre-war Luftwaffe Junghans marked Fl. 25591

The rim of the clock, as well as the metal components on the base are chromed.

Figure 71: The inside housing revealing a 1936 date and serial number 77

The inside of the housing is marked with “Eigentum der Luftwaffe”, the Junghans

logo and “1936”, “FL 25591” and the serial number 77. The housing of the movement

is made of more substantially made then on later clocks. The wooden base is lacqöred

natural wood.

Figure 72: Chromed metal backplate and clear laqöred housing

The second Junghans example is a 1939 example made for the Heer. The highly

polished chrome finish of the metal components has given way to a matt finish. The

housing of the movement has become less substantial.

Figure 73: Pre-war army Junghans Funnkeruhr

The face of the clock is still signed “Junghans”, but this being a Heer clock, the FL

number has been omitted. In all other aspects the face is the same as the earlier

example. The inside of the housing is marked with “Heereseigentum”, 1939, the

Junghans logo and the serial number “1563”.

Figure 74: The inside casing revealing the 1939 date and 1563 serial number

The wooden base is lacqöred natural wood, the bottom is marked with a Waffenambt

stamp.

Figure 75: Clearly laqöred housing and duller metal parts

The third Junghans example is a mid war example made for the Luftwaffe. The face

and the hands of the clock have become less ornate and clearer. The Arabic numbers

are slightly smaller than on earlier clocks.

Figure 76: Mid to late war Luftwaffe Junghans Funkeruhr

The housing of the movement is made of a inferior alloy with the back of the housing

being made out of Bakelite. The rim of the housing is now painted grey. The inside of

the housing is marked “Eigentum der Luftwaffe”, “Betriebsuhr bauart Junghans”,

“Gerät nr 127 – 558A”, “Werk nr 51258” (serial number), “Anforderzahl FL 25591”

and “Herst. Gebr. Junghans Schramberg”. On top of all this a BAL stamp has been

placed.

Figure 77: Inside bakelite casing revealing full Luftwaffe numbering information

The wooden base and all metal components have been spayed Luftwaffe grey.

Figure 78: Back of the clock showing the grey paintend housing and metal parts

Variations by Kienzle

Kienzle seems to have exclusively produced clocks for the Heer. The first example

has all the hallmarks of a pre-war clock, yet bears a 1944 date on the outer casing.

Figure 79: Early model army Kienzle Funkeruhr

The rim of the movement housing and the back of the housing are made of a zinc

alloy. The rim seems to have been covered in clear lacqör making it look slightly

yellowish. This inner housing is marked on the ring with “Heereseigentum”,

“Kienzle”, serial number “2407” and the year “1944”. The movement of the Kienzle

clocks is more substantial than contemporary Junghans clocks. The speed adjustment

is accessible on the side of the movement housing near the swivel.

Figure 80: Inner casing revealing the 1944 date and serial number and the army property

statement

The bottom of the clock is marked with a Waffenamt stamp, the matel parts appear to

be parkerised.

The second example follows the clockface design of the late war Junghans clocks but

the movement is identical to the clock shown previously

Figure 81: Late model army Kienzly Funkeruhr

This inner housing is marked on the ring with “Heereseigentum”, “Kienzle”, serial

number “529” and the year “1944”. The housing is largely identical to the Junghans

examples, painted grey (Heer clocks had a slightly more green grey colour than the

Luftwaffe examples). The metal parts are painted black. The bottom of the base is

marked with a Waffenamt stamp.

Figure 82: Late model Kienzly revealing serial number and army property statement

Variations Tobias Bäurle & Söhne

Tobias Bäurle & Söhne (TBS) is one of the rarer of the manufacturers and the

construction of the movement and the housing differs significantly from the others.

Interestingly, TBS gained the contract for manufacturing station clocks for the

Bundeswehr after the war, so caution is required by the collector when purchasing a

TBS Funkeruhr.

The first TBS example described here is an early model from 1940. The numberals on

the face are a squarer font, together with the substantial hands give the TBS a

distinctive, chunky look. (In practice this makes the TBS the easiest to read type from

a distance). The numerals are painted over with luminous paint. The movement

housing is made from pressed sheet metal, painted black.

Figure 83: Early TBS Funkeruhr

The movement is connected to a bakelite ring (rather than a cup shaped housing as

with the other manufacturers) screwed to the wooden base. Since there is no inner

housing, the manufacturing logo, year “1940” and serial number “134” are marked on

the winding wheel. The bakelite ring is marked with “Heereseigentum” and

“T.B.&S”. All metal parts of are painted gloss black. The housing is lacqöred in

natural wood. The housing differs from that of other manufacturers in that a recess

has been carved on the left side to enable the clock to swing open. This was

necessitated dö to the housing to be slightly larger in diameter.

Figure 84: Opened clock revealing the bakelite ring contaning serial number and army property

statement. Note the time adjusting wheel on the side of the clock facing the viewer.

The second TBS is a later 1943 dated example. Production had been improved

slightly. Even though the clockface is the same, luminous paint has been applied to

dots next to the numerals, speeding up production somewhat. The movement housing

is no longer painted black, but galvenised.

Figure 85: Late model TBS Funkeruhr

The bakelite inner ring found on earlier models must have been a weak point (it was

broken and repaired on the earlier model shown above) and this was replaced by an

alloy casting. The time adjustment moved from the side to the back of the clock. This

necessitated a redesigned inner metal housing.

Figure 86: Opened clock revealing the metal ring containing serial number, year and army

property statement. A Waffenamt stamp can be seen on the inner housing

The housing is now painted grey with galvanized metal parts.

Variations by Köhler & Co

The Köhler & Co example described here is from 1940. The face and hands are

similar to early Junghans clocks, but with larger round Arabic numbering. The bezel

is also similar to Junghans, but the housing of the movement is made out of stamped

sheet metal.

Figure 87: Köhler & Co Funkeruhr

The housing has a dull silver surface treatment. The back of the housing is marked

with “Heereseigentum”, “1940” and serial number “3736”.

Figure 88: Opened clock reveal the serial number and Army property statement

An ink waffenambt stamp has been placed centrally in the back of the housing. The

clock is also marked on the outer rim of the back of the movement. The stamp

consists of another Waffenambt stamp, “L – KU” and the date “9 / 40”.

Figure 89: Additional markings found on the back of the movement

The wooden base is lacqöred natural wood, the metal parts have a dull silver finish.

Figure 90: Back of the clock showing the clear laqöred wood and galvanised metal parts

Other timepieces used by communication troops

Other timepieces, particularly the “Dienstuhr” were also used by the communication

troops. The Dienstuhr, available as pocket- or wrist watch would be issöd to e.g.

Tornister Funktrupps. Some early receivers like the EP 2 had a specific hook and

padded backing to mount a Dienstuhr. This type of mounting is not widespread and is

not seen on later radios.

Figure 91: EP2 radio direction finder with hook and cushion for an Army "Dienstuhr"

Funkeruhr accessories

The Funkeruhr, being a relatively delicate piece of equipment, had to be handled with

care during transport and use. A leather carrying case was manufactured to transport

the Funkeruhr. The carrying case was purely a protective casing, with a single closing

strap on the side and felt padding to on the base firmly holding the clock in place

while in the closed container.

Figure 92: Leather Funkeruhr carrying pouch

A 1937 example of the first type case is marked with “Göttcher & Renner”,

“Nörnberg – O.”, “1937 and Waffenambt stamp. A slightly later example is marked

“dla”, “40” and a Waffenambt stamp. The second type example is marked “Karl F.

Hartmann”, “Berlin” without date or Waffenambt marking (most likely this was a

Luftwaffe example).

Figure 93: Carrying pouch showing the snug fit of the Funkeruhr

A second type, made from a converted pouch for a pre war field telephone dialer

pouch has also been encountered. This pouch has a belt loop stitched to the back

allowing the clock to be carried on the belt. It is not clear if this was an official or a

field expedient modification.

Figure 94: Dialling unit pouch modified to carry a Funkeruhr

This type example is marked “Karl F. Hartmann”, “Berlin” without date or

Waffenambt marking.

Some larger radio installations, such as the FU 9 SE 5 (Torn. E and 5 W.S.) would

transport the clock in a special slot in the Zubehör box Fu 21. The clock would slide

into a felt covered slot, firmly held in place by the closed lid of the box.

Figure 95: Storage of the Funkeruhr in the Transportkasten Fu 21 box

In vehicles, the clock was held in place by a special mounting. The mounting could be

screwed to the wall or radio frame, a screwed clamp could be tightened to hold the

clock securely in the mounting. It is shaped so that the clock can be opened without

the need to remove the clock from the vehicle mount.

Figure 96: Station clock in vehicle mount. The clock can be secured by tightening the wingnut

Synchronisation of time

Radio played a role in the synchronization of clocks on different locations. The

Kriegsmarine was transmitting a specific timing pulses on set freqöncies at 01:00 and

13:00 Middle European Time. Ships clocks, but also Funkeruhren of all stations

listening in could be synchronized to this signal.

Figure 97: Radio freqöncies and signals used for time synchronisation

As an alternative, the time could be synchronised through a manual signal. The timer

would start transmitting at 09:24 and would call all stations with “cq cq cq” followed

by “bt” (separation sign), “qtr 0925” and “eb” (waiting sign). At exactly 0925 he

would signal “bt” followed by “sk” (close transmission).
