[K3} RS232

A friend brought over his K3 which would not power up. Did a EE INIT and
it came to life, and everything seemed to work OK (very brief look).

He wanted me to update the firmware, but the K3 Utility failed to
connect fromthe Mac or a Win box. Both connect fine to my K3.

Any hints on a troubleshooting routine would be appreciated.

Re: [K3} RS232

If comport is set ok, then I would replace U1 on the KIO3 board.

KPA500 120/240

In reply to this post by alsopb

How do you change the AC input power from 120 to 240 on the KPA500 ?

I know the fuse values change and the fuse holder is turned to signify the
operating voltage, but does the rotation of the fuse holder to display 240
change connections inside for 240 volt operation?

If you wanted to switch from 240 back to 120 operation (for Field Day
operation), will it take a power cord that has a standard prong plug and the
larger fuses? Is that all?

Pete, W4WWQ

It's described right at the start of the Owner's Manual.

Yes! If you look at the prongs on the back of the fuse-holder, you'll
see an asymmetric pattern. Presumably this selects whether two
windings in the transformer are connected in series or in parallel.

It would appear so ;)
