[ik0yvv at libero.it]

Hi Guys,
I'm firing the IC 756 PRO III as second radio for the upcoming CQRJ but before starting the work i think i have a problem with the usual interface i use with my other icom (ic781).
Untill now i used the PRO III with his own decoder and with his buffer, but i'm sure to have read that the pro 756 need a special interface to be used in tx fsk with common sound blaster program .... can somebody help me? I thanks in advance.Read you soon.
