I'm getting ready to add a RX array which includes remote preamps and an
NCC-1 phasing unit.
I'm planning on sending PTT to the NCC-1 which will in turn kill power to
the preamps. As I understand the manual upon key down the PTT line goes
active immediately followed by a default 8ms delay before R

Make sure your preamp(s) do not have internal electrolytic power
filtering caps. If they do, there is a fair chance the caps may hold
the preamp on long enough for it to suffer damage. But, I am wondering
why you are using preamps at HF at all? Unless the feedlines are
extraordinari
These are short verticals. HI-Z AL24.
I'll ask about turnoff delay when I call DXE tomorrow.

Should have clarified: the preamps just match the short high impedence
verticals to 75 ohms. Voltage gain is unity but obviously power gain.
