I squeeze or stretch the coil in the MOPA to change frequency.  Sometimes 
when the wind gets to blowing and the antenna is swaying all over, the 
frequency goes up and down with the change in plate load.

You have to be sure not to grab the coil with the plate supply battery 
hooked up, though.  73

: No, my contest transmitter, a quarter kW arc transmitter  doesn't use
: crystals.  Too modern.  And what is an xtal anyway?

Small fry...  I Just dug up a 1 KW and 42 KW rotary spark gap while cleaning
the shop.
