[Elecraft] K2 with no TX or RX help please

[radio at modesgate.com]

Hi Don,

Thanks for this. You were correct on two counts. Working through your
list, I got as far as the KSB2 and, having subject that to a good wiggle,
everything is working again.

Many thanks for your help...I won't forget that the connectors can cause
problems and will check this kind of thing automatically next time I have
a problem.

Best wishes.....and yes, it was inside the box ;-)
