[Icom] AT-150 with other manufacturers rigs

Tue, 10 Dec 2002 04:52:21 -0800 (PST)

Hi Gary and Adam, the 2001 ARRL Handbook on page 22.39 has a complete
article to build the unit. Works with ICOM and YAESU rigs. It features
auto switching for ICOM rigs and manual rotary switched band selection for
non-ICOM rigs, looks pretty nice. The article indicates that most parts
are available from radio Shack and that Joe Carcia (NJ1Q) at ARRL
Headquarters has plans for the unit. Seasons Greetings, Ken
