Subject: [Elecraft] Using K2/KIO2 to drive antenna switch

Hi

Many of the outboard filters and antenna switches use a 4 bit code to select
bands. And  the Yaesu FT1KMP for example provides this band data output on
its back panel and some of the software progs also provide such band control
info  on the parallel port.

I have written a very short programme for a BASIC STAMP 2 which takes its
input from the KIO2 and performs the conversion to a 4 bit code so that a K2
+ KIO2 can drive these external filters or antenna switch ( and in my case a
auto switched linear.)

Want details? -  just drop me a note.
