[GreenKeys] Dovetron TUs

[Duncan M. Brown]

The AWA Museum has a Tempest Dovetron  MPC-1000T II, sn CRT607 with the SDS
switch, haven't figured out what it does, either.
 
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". 

I though it might be for autostart, but then realized there is no AC
(motor) connector like the ham units!
