The Universal M7000 Decoder is a vintage decoder used in the 80's and 90s
to decode digital modes that are commercial, amat or covert. It is a nice
piece of vintage gear for the utility monitor but may people still find
these units quite useful as general demodulators. The headers and routing
of most crypto is still viewable. The B/W monitor is included if you pay
the additional shipping. $250 Unit ships when moneyorder or cashier's
check clear the bank. USA and CA only.
