[CQ-Contest] Multi 2 locking device?

[kostas sv1dpi]

I forgot to mention also Op Swapper from TopTen devices. It is similar 
with 2S1 but in much better price. See

http://www.qth.com/topten/os.htm

Acom 2S1 and TopTen OpSwapper shares the same antenna to 2 radios with 
interlock to radios.

4o3a 1a2r switch shares 2 antennas to 2 radios (not interchangable) with 
interlock

and ea4tx interlock just interlocks 5 radios as you want (software 
adjustable) (you need to switch the antennas, amplifers, etc)

All devices work easy with big Yaesu and Elecrafts while you need an 
external relay for Icoms and Kenwoods (correct me if there is a kenwood 
with inhibit jack)
