[Elecraft] KX1 Recvr nearly deaf (Was KX1 receiver alignment)

[Ron D'Eau Claire]

Do you have the KXAT1 antenna tuner installed? 

If not, is the required jumper in place across pins 1 and 3 of J7 (page 41,
right column, last step of the manual). That's the three-pin connector
*closest* to the antenna jack. If so is it making contact with the pins?
Without that jumper, the antenna is only coupled to the receiver input by
stray capacitance across the connector. 

If you do have the KXAT1 installed, try removing it and inserting the jumper
and see how the receiver behaves. That would help isolate the problem to
either the KX1 itself or the ATU.
