Military Radio Frequencies
2. The Hungarian Army uses the radio frequency spectrum of 3,000 Kc/s to 7.000 Kffi.
The most popular frequencies used are selected between 3,000 Kc/s and 5,000 Ke s..
The radio frequency band from 5,000 Kc/s to 5,500 Ke/s is not popular and
is very seldom used.
3. Specific frequencies most used are the following: 3,200 Kc/s, 3,400 Kc/s,
3,500 Kc/s, and 3,800 Kc/s. Frequencies and call letters are changed every
24 hours for security purposes. Each station has a secondary frequency assigned
to be used only when the original frequency is jammed or blanketed by atmospherics,
High Echelon Signal Regiments
4. There are three high echelon signal regiments directly supporting the Ministry
of Defense. These are located in Budapest, in Vat and in the vicinit.7 of
Gyongyos. The one in Budapest is the 43d signal regiment located in the
"Petofi" military camp at Budaorsi St. 49538 in the 11th District. Tha 25X1
commanding officer of this regiment is It Col Moriez Fereao
5. In time of war, these three regiments can take.command of all arty cam-
cations, receiving their orders directly from the Ministry of Defense. These
regiments serve also as a liaison between armies and the Ministry of Defense.
Each of these signal regiments has approximately 800 men in time of peace,
which can be raised to 3,000 men in time of war. In 1955 the regiment stationed
in Vac had been subject to a big reorganization due mainly to disciplinary
measures.
6. Each regiment has a radio operators baatalion a teletype battalion and line-
men and telephone operators battalionZ t4 V. The following is a brew-
down of each of these three battalions:
a. Radio operators battalion: Approximately g00 to 1000 men in time of war.,
and 250 enlisted men and 25 officers during peace time. It is composed
of a hea radio company, a medium radio company and a light radio company.
[~ rat
(1) The heavy radio company is subdivided into three radio platoons.,
with two sections in the first two platoons, and four sections
in the third platoon. There are two Rff50 radio sets in the first
two platoons, and four R#40's in the third platoon. Each section
of a platoon has approximately six to eight men. These are:
the section chief, a commissioned officer.. the assistant section
chief,, a non-commissioned officer, a radio mechanic, three radio
operators, a powerman and a driver.
(2) The medium radio company has two radio platoons and a filler
platoon to back up the first two in case of necessity. Each
platoon is composed of three sections with one RI? type radio
in each. The personnel includes a section chief who is a non-
commissioned officer, two radio operators and a driver.

The light radio company has three platoons: the radio trans-
mitting platoon, the radio receiving platoon and the linemen
platoon. The latter is responsible for laying underground
cables and field telephone lines between the. transmitter and the
receiver sites. There are eight to ten R#20 and R#10 trans-
mitters in the first platoon with a commissioned Officer in
charge of 20 to 30 men, The receiving platoon has 4 receivers,
of modified Soviet type, made in Hungary, with a frequency cover-
age of about 100 Ke/s to 30,000 is/s. These receivers are in-
stalled in two trucks (seven in each) operating in conjunction
with R#50, R#40 and R`7 transmitters located at a distance of
about three to five. Km from the receiving site (truck). Under-
ground cables connect each transmitter to a receiver in the
truck. Every one of the radio operators can contact his counter-
part at the transmitting site by telephone through a 25 circuit
telephone switchboard. This switchboard has also many circuit
connections with the regimental headquarters to receive and
relay messages. ,[S tW The receiving station (truck) as
well as the transmitters are always installed in ditches as a
protective measure. Approximately, 150 cubic meters of dirt must
be moved in order to completely camouflage the truck. It takes
usually 15 hours for the radio operators to do it. There is a
crew of six to eight men at each transmitting site and ten to
eleven men at the receiving site. (truck) A radio operator at
at the transmitting site monitors continuously his counterpart
at the receiving station to enable continued communications
without interruption just in case the receiving station breaks
down. S ZeiC u
b. Teletype Battalion: Approximately 200 to 225 enlisted men and offiee~
in peace time. The battalion has three companies, each company having
three platoons and each platoon composed of three sections. In each sec-
tion there is an officer a non-commissioned officer, three teletype oper-
ators, and one driver. The teletype sets are "Siemens":tppe one in each
section. This battalion can operate independently from. the radio or wire
battalions. It has is own repair and maintenance personnel, drivers and
operators. 3J
~Skefic~ (Source was not well acquainted with additional
details of this battalion.)
o. Linemen and Telephone Operators Battalion: Composed of a light ;Line ccmapany,
a permanent line company, a heavy line company, and a switchboard telephone
operators platoon directly attached to the battalion. Each ceompany.is.
subdivided into three platoons and each platoons into three sections, ,SKe`4]
Each section has a comissioned officer in charge of the. operations, a non-
commissioned officer as an assistant, and five to seven linemen and Oils-
phone operators. Each of the above mentioned companies has the following
responsibilities.,
(1) The light line company is responsible for fast temporary wire
installations using short portable telephone poles, about two
to three meters high and five to eight Om in diameter.
(2) The heavy line company is responsible for laying underground cables
between companies, battalions, regimental headquarters, etc.
(3) The permanent line company has the responsibility of the fixed over-
head wire installations by using standard telephone poles between
battalions, regiments, divisions,, etc.
(4) The switchboard telephone operators platoon, which is attached
directly to the linemen battalion, supplies all of the switchboard
telephone operators to the signal regiment.
