Low P, 160M only

[JeremyJones]

So I was out on Sunday trying to make some contacts for the Rookie Roundup, as well as generally learning the ins and outs of my K2, and I found that when I try to tune on 160M I get the Low P error.  I've tried using a dummy load, 20M long wire dipole, and buddypole setup for both vertical and dipole at 40M, all with the same error.  I have the K2 power set at 10W, so I'm not sure if its just a poor antenna thats causing it, or should I be checking something else?

Jeremy,

Is the problem you cited a recent change in the behavior of your K2?  Also, do you have the KAT2 installed?  Since the problem occurs on 160 meters only, and even when using a dummy load, I wonder if the 80 meter/160 meter alignment procedure (see K160RX manual) needs to be repeated? The Lo P message could be displayed if you accidentally placed the K2 into "Test" mode, i.e. disabled the transmitter, then attempted to key the rig, but this would also be apparent on other bands too.

73,

Upon opening the radio to follow some of the trouble shooting advice given, the fault was easy to spot.  The wire on the L2 torroid had broken.  A quick rewind and reinstall, and everything is working fine now.  

Thanks for all the help,
