[Elecraft] KX2

[Don Wilhelm]

Andy,

What happens if you connect to a dummy load?  Does the KX2 tune it 
properly?
If so, then you know the KX2 is operating into a 50 ohm load OK.

Do you have an antenna analyzer?  If so, then connect it to the antenna 
feedline and look at the impedance - both real and reactive - as well as 
the SWR.
That will tell you whether the antenna is troublesome.

You specifically said an EFHW - that should be a resonant antenna.  If 
instead you have a random length wire (not a halfwave), and what is the 
matching device?
Many EFHW antennas need a counterpoise to work - that is why many 
manufacturers state a *minimum* length feedline.

If the problem is *not* the antenna, contact Elecraft support.

I’ve checked the continuity in the wire and also the continuity in the KX2 between the BNC connector and where the wire connects inside the KX2 (as I removed this to fit the end panels). Battery is at over 11v. Any ideas please?
