[Yaesu] QUADRA-REPAIRED

[KC3VO at aol.com]

FIRST of all, it is VERY LIKELY that your QUADRA is WORKING  NORMALLY!!---HOW?
  Operator trouble! Flip the little SWITCH on the top rear center of  the 
R.F. deck, and see if your "ERROR" message goes away! (Excessive PA  Voltage)  
The resistor that failed often fails due to power interruptions  during 
operation, which causes rapid RE-START cycles, and overheats and blows  this 
"Start-up" resistor, which is not rated for MULTIPLE starts in rapid  sequence, or 
starting UNDER LOAD. (Mine also failed, due to problems with a  generator I was 
using to power the QUADRA. I fixed it, and added an AC  capacitor, so it will 
NOT happen again)-73, KC3VO-Bob  Curry
