vfo-230 fine tune mod correction
 a note published in your t/k newsletter of january, 1983, issue no. 30, 
concerning a fine tuning mod for the vfo-230, impelledme to purchase a 
new vfo-230 for the sole purpose of obtaining a slower dial tuning rate 
for my ts-380s.  then the combination of a defective new vfo-230 and some 
bad information in your newsletter note triggered many, many hours of 
frustration and irritation over a period of several months starting in june 
1986.  i believe you should know about it when information in your newsletter 
causes frustration and irritation.
 i decided to try the diode cutting bit again.  it did not work.  
the optical dial encoder went crazy.  i was ready to explode and did.  
Fortunately there was nobody around to hear me.  back to the drawing board.  
now i know practically nothing about optical encoders but i do have an 
engineering background so i spent some time staring at the vfo-230 
schematic in the ts-830s service manual.  suddenly the light came on.  
ka0nnf gave you the wrong information about which diodes to cut.  
(his call is not wa0nnf as given in your newsletter note.  i tracked him 
down by telephone.  he told me he had sold the vfo-230 and couldn't remember.)
