[Elecraft] KX1 Poor 30m sensitivity

[Paul Barlow]

I built my KX1 a few weeks back, and I've been on the air with it a bit.
Yesterday I did some serious measuring of its performance and discovered -
to my embarrassment - that it's quite a lot less sensitive on 30m than on 40
and 20. About 20dB worse in fact.

I've tried peaking the trimmers again, but I don't seem to get any
improvement. One trimmer seems to have an effect on received signal
strength, the other doesn't seem to have any effect at all!

I have reheated all the joint on the module. Any suggestions of where to
look next? Perhaps a duff trimmer? Naturally I don't want to unpick the
module unless I have to.

The module does have the desired effect on the 49m broadcast band receive
BTW.
