[ICOM] CI-V "transceiver" mode?

Doug,

I must apologize...  After taking another look at "A Low-Cost Remote 
Antenna Switch" article in the April QST, I realize that my controller, 
as-is, will not work with this relay sub-system...  My controller uses 
an Allegro 8-bit Open Collector relay driver chip to sink the "low side" 
on a relay sub-system...  I'll look at some of the other Allegro parts 
to see if they have a pin-for-pin compatible "high side" switch...  
Gosh, if they do, I could provide both "low side" and "high side" 
switching with just a part swap...

Regards, Mike - K8LH
