[Elecraft] KAT2 Lo-P message

[Bob Towers]

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.
