Motorola SECTEL 3500 Phone #2
Motorola 3500 SECTEL Model 5DGT3506XA STU-III (Secure Telephone Unit) phone for secure voice/data/video transmission.
Operates in clear (analog) or secure mode over standard "home" telco lines. Requires power supply (left). New price was around $3,500.00... hence, SECTEL 3500? For encrypted mode two sets are required. Will go secure without the key... press the secure button and handshaking starts. Very simple to deploy and use.
Still used for government communications, very effective for protecting sensitive conversations.
