Hi to the group
I am in the final phases of finishing my KPA100, version "C" with
upgrade kit for "D".version. Manual page 46 (version C manual)
External Amplifier Keying Test (PA KEY),
right hand column, step 2, "measure ground to Q9 tab. Result as
noted in the manual.
right hand column step 3, Hold TUNE. When I do this the DMM reads 3.2
Ohm, as noted in the manual, but as soon as the reading starts, when
holding TUNE, the Ohm reading starts to increase, at a steady pace. At
around 8.9 or 9.2 Ohm the fuse in my power supply, 20 Amps, went,
replaced it with a 25 Amps, did test again and this time the 20 Amp
fuse in the power cord went,
There was no smoke or smell at the time this happened. I did have my
50 Ohms dummy Load attached to the antenna as a precaution.
Any help would be appreciated. Thanks, Hank WA9QJH
