The field station FS 5000M (also known as "HARPOON")
was developed in the 80s by AEG-Telefunken © in Germany.
It was meant for "stay-behind-organisations".
In case of an invasion, military groups stay in the country, they report the goings-on, do reconnaisance or sabotage.
The complete system together with the base station BS-5000, is called SY-5000.
The field station FS 5000M is the portable part of the telecommunication equipment, here with batteries BA 5001 M.
Encrypted signals can be received from or sent to the base station BS 7010.
All modules are connected by spezial connectors, then they are locked mechanically, forming a solid unit.
When locked, the following operational elements are accessible:
Connectors for long wire antenna
Connector fpr counterweight
Display and keyboard of the memory
Connector for the ear plug
Sealed frequency normal (for servicing)
The station FS-5000 is a modular radio, and consists of the following modules:
Transmitter S 5000M Transmitter unit (lower module) and ATU (upper module) ;
are coupled by connectors , and screwed together.
Receiver E 5000M (receiver part and synthesizer); is powered from the transmitter.
Double module OSU (up) and battery charger (down)
Memory unit SR 5000M: usually powered from the station. When disconnected from the station,
built in (not rechargeable) Lithiumbatteries take over . So the unconnected memory unit can be used to enter or issue
Up to 10 texts can be entered, encrypted and stored. Received texts
are decrypted and issued.
Connecting cable VK 5000M (1200 mm long). Is used to operate the memory unit outside the radio set.
Station battery BA 5001M with 12 NiCad- batteries, and fuse 10A, slow.
Instead of the the Staizon battery BA 5001M, a battery BPU 7000/1 (non rechargeable primary battery
with adapter cable and strap) may be used (not in the collection).
1 test adapter, used for:
testing the interface to the memory unit;
testing transmitter and ATU;
at emergency ioeration replacement of the ATU.
2 dechargeing flaps; needed for slowly dechargeing the battery:
dechargeing current 25 mA,
displayed by green LED,
low dechargeing voltage 12V.
1 adjusting pen
2 banana plugs
2 lithium batteries for memory unit SR 5000M
3 spare fuses for the station battery
3 spare fuses for the PSU
1 extendable rod antenna
accessories outside the accessory box:
Dechargeing adapter : used for quick dechargeing of the battery:
dechargeing current 1.2 A,
starts when plugged onto the battery,
displayed by green LED,
dechargeing time abt. 1 hour.
The H- adapter
is used to charge the batteries BA 5001M from the PSU
The TM also mentiones as accessories:
Long wire antenna LWA 7000, 15m wire as antenna, 2 x 10m wire as counterpoise (not present).
