[GreenKeys] Any ST-8000 helpers around?

[William Wuttke]

Kevin,
The regen feature works on mine - tested with 45 baud baudot in and 110
baud ascii out. The fast/slow tuning rate via the missing front panel
switch is available only with version 2.0 of the firmware. My units both
have 8 memory positions marked on the front panel, however an old data
sheet with a picture of a front panel with 3 memory positions marked
describes 8 memory positions in the specifications.
