K2/100

[Elecraft mailing list]

I built my KPA100 14 years ago in a separate enclosure and it still works
fine. I wonder if the upgrade kit would provide improved performance. Any
feed back will be appreciated.

Larry,

The KPA100UPKT totally revamps the T-R switch section on the KPA100, so
the answer is yes.
There is a chance that there may be a nasty spur when on 40 meters - at
about 8 MHz if you do not have the upgrade.

Do you happen to know at what point the upgrades were included? Is there
an easy way to determine if the update is present or Not?

Doug,

Peer into the side of the KPA100 (the side where the coax and power
connections are) - If you see blue toroid cores, the upgrade has been
done.  If you can only see red toroid cores in about the middle of the
board, the lastest update is not installed.
