Secret Communications 3
My wife
Karin
has designed an invitation
for our
Secret Communication 3
event
which, Deo volente,
has been scheduled for autumn
this year.
It may be duplicated for private use only.
The bulk of the shown displays aren't ours, but owned by the Crypto museum in Eindhoven
Though, the German set in the centre with
Achtung!
Feind Hört Mit
Is our second
German
Speech inverter (Invertierer)
which will arrive tomorrow
My aim is to build up a two-way communications by two sets each one at one end of our Museum premises; on both ends communicating through genuine field-telephone type FF 33
I would like to attach a loudspeaker and de-tuned de-scrambler as to so the weakness of such system (generally)
However, the bulk of shown devices aren't ours, but in the possession of the
Crypto Museum Eindhoven
