To establish communications under conditions, where VHF frequencies as
used for military communications are not suitable (too long distances, no
direct sight distance), the Swiss Army does still rely on shortwave communications
for ionospheric long distance connections: The Racal Syncal with the Swiss
designation SE-226 has been acquired in the early eighties.
The transceiver can be used as portable backpack set powered from internal
accumulators and a telescopid antenna, or it can be used as a vehicle based
mobile transceiver or feed an inverted V dipole antenna for longer distances.
There is the possibility to control the SE-226 from the remote control
set Fernbetriebsgerät FBA-227/412.
The operation scheme is very straightforward:
Attach a charged NiCd accumulator to the bottom face of the set; the accumulator
charger can be fed from 12 or 24 Volts DC from a car battery or from 220 V mains.
The "Mikrotel", the telephone - like handset wit ha speaker and a microphone
and the push-to-talk button is plugged in at the left side of the set, the whip
or the dipole antenna connected to the corresponding sockets.
Use the modes switch to select AM VOICE for AM mode, or VOICE LSB or VOICE USB
for single sideband or telegraphy operation, the same switch acts as main switch.
Use the four decadic knobs to select the operation frequency.
The volume is changed with the GAIN gain control, in transmit mode, You can
select from HIGH or LOW POWER. Use the TUNE position of the modes switch to
regulator for maximum antenna current with the TUNE control and then change
over to VOICE AM or VOICE LSB/USB for a connection trial. With a sufficient
signal strength, You might to try reduced power (LOW POWER), to save
accumulator power and limit the range for reception and interception...
No, I do not yet possede a SE-226, just in case, You have an unused one, drop
me a note...
