A simple field expedient technique to overcome the  heater warmup delay for 
fast break in voice operation is to put the mode  switch in the MCW position 
adjacent to the VOICE high power position prior to  transmitting, then put it to 
VOICE high just as you key the mic. The heaters  run full time in MCW as well 
as CW.  Just need to repeat the drill prior  to every transmission, or once 
you are in a QSO, just wait for the output to  come up in voice after telling 
people yuo will have a slight delay each  time.  On my set you can hear the 
dyno slow a little and see the power  output come up on the neon bulb as a cue to 
start talking.

Gene any more input on the AS-2259.?
I've worked  up several matching schemes but the best is just a simple  
T-match.
Variable cap on the input to an adjustable roller inductor and  then a fixed 
cap on the output.
Most of the equipment out there that is  commercial and  has an autotune 
feature use some version of the  T-match.

The antenna works but as I mentioned before I think it would  be easier to 
make the elements longer for 75/80 meters and thus make it  easier to match.

I will add the comments on water sneaking into the  mast connections, and the 
guy lines are very old on these antenna and  not  really suitable for 
extended outdoor use.

I have  taken  several photos and designed a "plumbers delight" connector for 

the bottom mast and will try and put  the photos and connector  details on my 
little web page.  Any input from your end would be  appreciated.
