I have a friend who has a TS870s and he is having problems working out how to hook up his PK-232 so that he can use FSK I keep telling him to trade it for a 1000mp and then I could help him (piece of cake on an mp)... I don't want to embarass him any more than I already have, so if anyone can send me the info I will pass it on. John - vk4cej
