IC756 ( all series ), IC7400, IC746, IC7000

(Personal Computer not required)


IC-756, IC-7400, IC746 and IC-7000 have a built in RTTY decoder but RTTY transmission is very hard because Keyboard isn't provided.

This interface can be used to add a standard PC Keyboard to some ICOM TRX.

Also CW transmission can be performed so, for this use, can be used as CW keyboard with all commercial or home-made TRX .

Ideal for portable operation because PC isn't required
