K2 Problems

Brent Sutphin WB4X
The symptoms I explained earlier were after an electrical storm
that also took out my cable modem and wireless router.  The K2 was connected
to its antenna but was turned off at the time.  It also had the KPA100 and
KAT100 installed.  I decided to remove the KPA100 and KAT100 to see if I
still had the problem with the basic K2.  I wanted to see if the high
current warning was
still there.  The high current warning did not come on but the power
transistors became very hot very quickly. I was not transmitting. That led
me to believe
that the power transistors were defective. There very well could be problems
with the KPA100 as well.  Now I'm not so sure.

Re: K2 Problems

Brent,

Take it one step at a time;  Yes, all could be damaged - the base K3 PA
transistors, the KPA100 wattmeter diodes and the KAT100 wattmeter diodes.

I feel your pain - I recently had a very close lightning event that did
not come in on the antennas, but got me on the Ethernet connections - I
lost 4 computers and a router and 2 network switches.   Fortunately for
backups, I did not loose any data

I don't know how "hokey" your backup mechanism may be, but if it causes
you any amount of grief at all, it is better than nothing. All it takes
is one  event to convince  you that regular backups is the only sane
answer.  Your data is valid, whether that be just email or whether that
includes downloads and document files

73,
Don W3FPR
