[GreenKeys] Re: Tempest Dovetron

Don, Larry & Jack - Thanks for your comments. We have an UGC-74, so maybe
we will connect it up to the this Dovetron.

As for the model details on this unit (which I forgot to mention in the
original post), it is a MPC-1000T II, sn CRT607 (date codes: 1985). It
includes the Solid State Display, Binary Bit Processor, TSR-200S
Regenerator board and diversity & scope connectors.

Besides the SDS switch on the front panel, the TSR-200S board has a "SDS
CONTROL" switch labeled "ON/OFF/TEST". Near the switch are two PCB pots
labeled "TURN OFF" and "TIME OUT".  On either side of each pot there is a
label "SLOW" & "FAST".   Any idea what "SDS" is??

Thanks & 73,
