[Elecraft] KAT2 Lo-P message

[Ken K3IU]

Hi Bob:

It has been my experience with several KAT2s that the KAT2 will "tune" with
anything *Greater Than* 0.1 watts commanded on the Power control where it
shows "Lo P." I think you have something else wrong there.

Good luck...

I think this is a low power message indication that the atu isn't seeing
enough power to do a tune.  You might want to check the cable between the
atu and the rf out jack on the motherboard.  It can come loose and can also
become damaged with the removal of the lid, etc.  Also make sure the ribbon
cable is seated properly.  Does it only happen on an antenna, or does it
also happen on a dummy load?

Philip,

I've only recently installed it and the cable from the ATU was locked well
into place. I'll check, anyway. I'll also have a go with a dummy load.

I think the general view is that I'll need to set the power level above 2
watts before I do the tune - it works OK then.

I'm running it into a rather ancient Kenwood TL-120 linear which on occasion
doesn't present a well-behaved load to the K2, so I get the ATU on the K2 to
cope with it. If I set the power on the K2 much above 1-2 watts, the linear
doesn't seem to like it ie trips out.
