Just a note about a situation I discovered after assembling my KPA500.
It is very easy to snag the fan voltage wires at the rear of the KPA500 when
installing the rear panel if you're not careful. If it happens it will unplug
the power to the fan. It happened to me, but I noticed the heat
Many thanks for the helpful suggestions on and off-line. Given all the
problems with Serial to USB adapters I am going to install serial PCI cards
in my PC and then connect the correctly wired cable from the K2 (I
understand it is not a true RS232 port on the K2) to a new serial port on
the PC.
David,
I don't think I would use the figures other folks suggest. There are too many
variables involved; watt meter accuracy, the accuracy of your dummy load and
your line voltage would be the first three variables I can think of.
Elecraft can set the power adjustment at the factory, but that

the top cover off to see how possible this is but my
Tim,
That's not the same issue - top of my Z-bracket (at the front only) is
flush with the outside face of the top of the front panel, so the top
panel is pushed up by its own thickness, and cannot be pushed down.

make it pop back flush and then retighten the screws but that didn't help.

All,
I feel I should add to the discussion the fact that these consumer
quality USB to Serial adapters typically do not like to work at lower
baud rates - the K2 uses 4800 baud. So an adapter that works at the K3
rate of 19.2k may have trouble when attempting to drive a K2.

Well, might as weell tack on a couple of additional questions.
1. Is the delay between the keyline going down/up and the onset/loss of

I would add the fact that the consumer quality USB to Serial adapters do
