[1000mp] ALC high- FT-1000 Mark V field

[Rob Atkinson]

If your ALC response is obviously too aggressive for example you can't 
get full output or full peak output results in it going way beyond the 
red line, you may have a problem with RF getting back into the rig to 
give the ALC circuit a false trigger.     experiment with removing 
cables, putting ferrite chokes on the ones that have to remain hooked 
to the rig,  maybe a coax choke on the feedline, try removing the 
ground strap to see if that makes a difference.   first, tx into a 
dummy load and see if ALC changes (without doing anything else).  Try 
this antenna then dummy load on several different bands.   if your 
results vary from greatly from band to band, and/or you get some 
distortion on peaks, you probably have a common mode  RF problem.  i 
think the yaesus are a little less sensitive to the RF problem than 
kenwoods.  to get my kenwoods to work right i had to do all of the 
above.
