[ICOM] IC4KL - no 40 volts

[Larry Dighera]

Hello Dave,

You will find a lot of ICOM IC-4KL information on Matt Erickson's old web site:
<https://web.archive.org/web/20140104115619/http://kk5dr.com/>.  Mr. Erickson
has chosen to remove his valuable content from the Internet, but fortunately it
is archived at the above link.  You may contact Mr. Erickson at:
kk5drmatt at wildblue.net  

Best regards,
Larry
