[Elecraft] K4 introduction manual link updated

[Wayne Burdick]

Our "Introduction to the Elecraft K4" manual link has been updated to revision B4. This rev includes preliminary specifications (page 40). Additional specs will be added in a subsequent edition.

Here's the direct link:

    https://ftp.elecraft.com/K4/Manuals%20Downloads/Intro%20to%20the%20Elecraft%20K4,%20rev%20B4.pdf

This manual is landscape format, 8.5"H x 17"W, to allow for K4-sized drawings. It includes approximately 35 full-color illustrations of the front and rear panels. (A printed copy will be supplied with the radio.)

Comments and suggestions welcome.
