You're right, at least right about one we converted to 220 a year or so ago http://home.comcast.net/~micorrepeater/ . I don't know the model number, but it's a hi-band VHF 100W continuous machine in the tall cabinet. How do you handle the IDC adjustment? We ended up having to adjust IDC for 800 - 1K PL deviation and left it there, setting the maximum deviation via the controller. I considered figuring a way to modify the PL card or the exciter so that the level could be adjusted independently of IDC. That puppy was a real learning experience for us novices. de WD7F John in Tucson

The Micor is one example of fixed values for tone deviation.
