OK you guys. Let's look at something else here. Anytime you are looking at electronics any change needs to be by the book. Ham radio taught me that years ago. especially if its a TX that propagates a radio wave. However, Looking at Futaba's FP-R147DP and FP-R148DP Rec. The only thing I can see diff between high band and low band is about two inches of Ant. and in fact, looks fare on the service mon. I have not looked at the older Futaba Rec. and can't comment on them. By the same token, we can't have just anyone sticking a screwdriver in there radio's and bringing them out to the field. What do you all think of this??? Hooker53
