[ICOM] 75 PRO III Smoked!

[Stephen Budensiek]

FYI: you can download one file a day as a visitor.   Any item you
click on is considered a download, so you have to wait till the next
day to go back and download something else.   I still haven't figured
out where I downloaded my copy, I know what it was named from the
download, but failed to save the link.

73's de Stephen, K0SD
