I simply put a momentary switch in a mini box wired across the key line.
Hold it down as long as you need.The max key down time at max power on
the 811h is 7 seconds per the manual. Was LOL at the send dits at 35
WPM. Try dipping the 811h to resonance while bringing up the drive with
one hand in 7 seconds. The 811h doesn't peak resonance at low drive
then just turn the exciter drive up. It must be 'tweeked' at full drive
as per the manual. Lots of work with just one hand in 7 seconds. LOL.
That's why my 811h is on the XYLs desk where she mostly contests single
band SSB & I use a KPA500.
With the auto set on the KPA500 I still tap it for an instant to
see the LEDs light correctly. Just in case I am on the wrong antenna or
some other problem.
Parts are under $10 & it makes using an 811h a lot easier
