CZK - SUD (spojovací uzol divízie)

Liaison node of the PRC division.

From 1976 onwards, Soviet-made divisional communications nodes were purchased and replaced with our inadequate SUD 1-1 nodes, which did not allow covert telephone or telegraph communications.
As a replacement, Tatra 805 (so-called "Kachena") units were used until this time, modified for a classified telephone connection with the possibility of connecting five subscribers.
Soviet P-240T and P-241T (GAZ-66) junctions were supplied with small trailers. Subsequently, they were modified in our country into the P-240T, P-241T (without trailers) and two P-V3S escort vehicles.
The modification of the coupling junction to the CSRL sub-units, was based on the comments of the commission at the military trials.



Removed from P-240T:
R-405MSP-R - radio relay dual band VHF station - semi-complete,
BUM-M - power amplifier of meter (60-70 MHz) band to R-405MSP-R,
BUM-D - decimetre (390-420 MHz) band power amplifier to R-405MSP-R,
PRK - antenna input/output mixer block for R-405MSP-R,



Supplied to P-240T:
R-138 - duplex VHF radio (76-94 MHz), for remote control of the R-140,
K-STT-1 - tone telegraphy set, with a keying allowance of 0.3-2.4-2.7 kHz,
JRV-1 - single radio transmitter and receiver of 2,1 kHz tone call,
SUR - central distribution terminal block - cross unclassified telephone connection and line dispatching.



P-241T remained unchanged:
Both vehicles underwent power and protection modifications.



Two P-V3S escort vehicles delivered:
The SU Chief's office with telegram dispatching office in the front and the Supervisor's office for communications in the other.



Workplace equipment:
TU-11, PA system, MB phone, battery charger and batteries.
In the back stored the node building materials, two each of power packs, cable spools, P-170E, TA-57 telephones, antenna accessories for radio stations, cable reels, masking nets and other miscellaneous auxiliary materials.
