MASON Mod. A2
Spy Radio Receiver with Spectrum Analyzer
Year 1965
Manufacturer MASON ENGR. CONN. USA
I m interest to find the manual.
The Mason
Engineering A-2 Receiver System was designed primarily to answer the need
for a truly portable, wide range, communications receive.
Because it consist of a basic unit wit small plug-in tuning modules, many
special types of tuning heads can be designed, such as wide range tuning,
crystal- controlled fixed frequency, or crystal-controlled discreet channels.
Also any type of power supply battery, AC/DC converter, or DC/DC inverter,
can be used and can be easily changed in the field. It s light weight and
small size make it ideal for use in remote areas, aircraft, vehicles, and
ships.
Many special features were incorporated without increasing the size or
weight to unreasonable proportions.
The unit was engineered with versatility being one of the prime objects thus
allowing many users to benefit. The MODEL S-1 attachment to the A-2 RECEIVER
provides a swept visual display of the signal received, in a small battery
operated package.
Lightweight headset are supplied for normal listening to AM, FM, and CW
signals. A signal strength meter is included for visual indication of
relative strength of the signals being monitored.
A unique visual monitor aids greatly in signal searching applications.
The tuned frequency and adjacent spectra are scanned and presented on the
display tube.
Signals thus monitored can be analyzed for relative signal strength, type of
modulation, and other technical information.
Each turner unit has a direct frequency-reading tape dial.
The dial are individually calibrated.
A total of eleven turner units cover a frequency range from 2-kc to 1200-mc.
Each turner unit has its own tuning element, specialized circuitry, and
calibrated dial.
This permit maximum sensitivity and selectivity without compromise.
Having separate tuning, control, power and output units allows for simple,
in- the-field changes for repair, special setups and future replacement or
additional units. As an added feature, antennas are interchangeable and can
be plugged into the turner receptacle. |
