Setting up a DXE NCC-1 noise/phasing unit with my K-line and a simple amplified receive (noise) antenna and need to confirm the right delays for the various parts of the system.
Here are the typical delay times indicated for the DXE TVSU-1 sequencer for solid-state gear:
PTT: 10ms (VOX will never be used as per the DXE manual)
CW: 10ms (won't be using CW mode except for tuning up) I operate SSB only.
AUX: 0 ms (T/R switching)
PREAMP: 20ms (using a DXE RPA-1 with 102" vertical wire)
LINEAR: 16ms (is this fine for the KPA500?)
The receive (noise pickup) antenna will be more than 1/10th wavelength from my closest xmit antenna and actually close to 1/4 wavelength away but I often run 600 watts to both of my HF verticals.
If anyone knows the best or recommended delay times for Elecraft gear I'm all ears---hope to get this up and running before the CQ WW this weekend.
