info, accessories for TR-711 DEI receiver
 

I still have a DEI TR-711 telemetry receiver. Apparently these have
been popular so I hope someone has a tech manual or some additional
plug ins. It has some nice features (say for radio astronomy) like
bandwidth controls and plug in IF filters, AM and FM demod,
etc. My unit has a front
end for 50-200MHz for instance. Anyone have anything else on or for
this 1970's receiver?
