Please ignore post.

I finally found it on page 12.5 of the FULL User Manual.
It can be set to off (which is disastrous), and then 10 to 30mS in
increments of 5 mS.

For Ameritron Amplifiers without the QSK-5, it should be set to 25mS.

Sorry I Spammed the group.

Hi guys and gals,


A friend of mine (also OM6 user) just purchased an IC-7300 and wants to run
it with his AL-80A (slow open-frame relay).

He asked me if the 7300 can be adjusted for proper CW amp keying timing.


I know that he will need:

..> About 25mS TXD (delay of RF after keying the Amp Key line)

..> About 200mS hang delay


I found in the manual how to adjust the hang delay but I can't find any
description of the default RF delay or TXD adjustment.


Anyone here been down that road yet?
