dr om, thanks for your curiousity.
I have a "telemetry receiver" model TR-711 (#1234).
The receiver is made by "Defense Electrinics Inc." in
Rockville , Maryland, USA. Probably late 60's.
It consists of blueish-grey 19" frame with plug-in units.
At the left part of the front panel there are 4 meters : "deviation",
"tuning", "output dB" and "signal level dB above noise".
Each plug-in unit has a different serial number.
The main chassis has serial number #119 and all plug-ins have similar low
serial numbers so I suppose not many sets were produced.
Units comprise tuning, filtering, AM/FM demodulation and a panaramic display.
The tuner range is from 55 - 260 Mc/s, mechanically tuned coils (!).
The set has an audio and a video output connector.
Video filter bandwidth selectable from 6,25 kc/s - 20 Mc/s.
It is a nice set which has been slightly modified by a previous owner.
I would like to have information on this equipment.
Preferrably an operations manual and a circuit description / schematics.
If you can help me I would be very grateful for your cooperation.
Please contact me to make the necessary arrangements.
Thanks in advance.
73 de PE0WDM , Wim
