[Elecraft] MP-1 Antenna KX-1

[Howard W. Ashcraft]

I have recently tried an MP-1 antenna with my KX-1.  I used the small tripod mount and adjusted the antenna per the diagrams.  However, this led to a SWR of 5.9.  By moving the coil, I was able to lower the SWR to 2.0--but no lower.  And it was exceptionally sensitive to adjustment.  Moving the coil by a single turn of wire would jump the SWR to 2.0.  In comparison, the KX-1 tunes on my Steppir IR vertical to no worse than 1.2 (with the autotuner engaged), tunes reasonably well on a 40 meter dipole, and tunes well with the random wire recommended by Elecraft.  Is my experience with the MP-1 similar to others?
