[CQ-Contest] An optocoupled isolator for Yaesu CAT

[ik2bcp@hamlan.org (Guido Tedeschi, ik2bcp)]

Hello All,
    I designed a simple optocoupled isolator for connecting the CAT
interface of our Yaesu FT1000MP MK5 to a PC.
The optocoupling avoids electrical and RF problems that you can have with a
simple RS232C cable in a contest environment.

Ciao and 73
