Hi all, yes D28 was in short circuit... i leave it and now the radio it's
working.. but without the Kpa100.. the same diode/zener on the Kpa100
module it's in short circuit also.
Now i have to find where to but 2 of the D28 diode...
thanks to all !!!

Hi,
today i was in QSO in 17 meter band CW when my power supply (switching from
Nissei model MS 280A) has shut down (i was in tx with 100 watt). After i
discover that the supply is death.. and also my K3 (#4777) now it's death
also..connected to a battery it's not swithing ON... nothing...
any
Did you confirm cable and fuses are good?

yes cable it's good, there was no fuse on cable from K3 to the supply.
I just check the K3 with a battery and it's seem that the K3 it's in short
circuit.. the battery voltage go to 12v to 0.5v when connected to the K3..
can be the fuse inside the K3 ??

Perhaps before die, the 280A delivered an overvoltage output. That could
explain both the death of the 280A and the short of the K3.
Obviously, I hope to be wrong
