Radio is K2 No. 2005 w/ all options and latest firmware updates. Attached is the remote K2/100 with the KAT100. I did in the past have erratic behavior from the KAT100 until I installed the shield mod kit. That seemed to clear up the problem until recently. Now the gremlin seems to have come back for some reason.
The problem only seems to come when the power range switches to high. But before you jump to the conclusion it must be stray RF (it may be though??) when the unit is tuned on to the max low power setting (10.0 watts indicated) the erratic tuning will not occur. BUT when power is ever so slight increased to 11 watts (so the KAT100 is utilized) then the tuner goes into an infinite loop of tuning. Goes to SWR red bar of 5 down to 1.5 green bar or so then immediately jumps up to red bar of SWR 5 and so on. After the first cycle it goes to low power (normal behavior if it cannot find a match) and continues to futilely search for a match. Same behavior on a dummy load or my Quad So is it still stray RF? Perhaps a failed component? All the inductors and caps switch audibly when cycling through the menu. My gut feeling is that maybe it is stray RF. Yes I have read the KAT100 manual which lists numerous suggestions to fix the problem. I have not yet implemented all the suggestions but is there a fix which more often than not corrects this problem?
