A British voice encryption device used with (for example) Larkspur radio system sets.
BID means 'British Inter Departmental'. These systems or equipment types were generally used by more than one single governmental agency or department. The authority for BID's are the Communications-Electronics Security Group (CESG) who are part of Government Communications Headquarters (GCHQ).
The BID/150 speech encryption key generator is a single channel device for use with the British Army C42 and C45 Larkspur radio system. This was the first Combat Net secure speech system whose key was set through the use of punch cards within the device. Examples of the BID/150 are on display at the Royal Signals Museum, Blandford Forum.
It was first used operationally by the 15th Signal Regiment during the Aden crisis in the late 1960s and was widely used from Battalion level up to Corps Headquarters. It remained in use until the early 1980s.
In secure mode the analogue speech signal is digitized, then encrypted by combination with the digital key generated by the BID/150; the digital stream is then fed to the transmitter, to pulse modulate the carrier. On receive, the sequence is reversed.
I am a throwback to primeval age
I'm easy to anger I'm quick to enrage
Get in my way and you forfeit your life
I'll orphan your children and widow your wife
Fight now! Til' ther's only one left
Right now! I will lay you to rest
I am the bringer of of thunder and pain
My fists of lead fall upon you like rain
Resistence is futile your fate has been sealed
I will not stop until you have been killed
Fight now! Til' there's only one left
Right now! I will lay you to rest
Cry out! With your last dying breath
Die now! As I beat you to death
I need no weapon to bring you to heel
My fist in your face is the last thing you feel
Beg me for mercy and see what it gets you
My only real pleasure is getting to hit you
Fight now! Til' there's only one left
Right now! I will lay you to rest
Cry out! With your last dying breath
Die now! As I beat you to death
I have no room in my heart for compassion
If you piss me off I will simply start smashin'
Your pleas for reason are simply pathetic
Why waste my words when my fists are poetic
Beat you down
To the ground
Break your bones
Final blow
And blood will flow
It's clobberin' time!
I hate you I hit you [x7]
