[Elecraft] K3 no xmit, no receive?

[James Wilson]

Tom,

Since you receive white noise, before you dive into
the K3, consider that there is an item that is  common
to all three antenna   inputs. - The BNC connector
and coax to the BudiPole.

Try another independent antenna into the antenna
input you have active. Just a few feet of wire as an
antenna will give you some signal reception.

Then try transmitting into a dummy load using a
completely different coax and connector.

Just suggestions.
