Hi again,
In my first post I miswrote a thing or two and much confusion as to my question ensued. Hopefully I've written this more clearly. Thank you to all who responded to my earlier question and my apologies for wasting your time by having you answer the wrong question. I have a wp-639. I'm its at least third owner and don't know its previous history. It's got a factory sticker marked 146.97 / 37. I don't know anyone who currently has the correct equipment locally and I don't have the budget to take it to a radio shop so I've used alternate methods of tuning similar to mentioned on the repeater builder website. I've gotten it tuned to work OK with my repeater on 146.88 / 28 but I'm guessing it could be better. In tuning the pass adjustments, there was a definite "sweet spot." Go a quarter or a third of a turn off of that and there was a definite difference. But I didn't find that "sweet spot" in tuning the reject and I wonder how wide of an adjustment it usually is. What I mean is, for example the pass tuning went from "not very good" to "good" to "not as good" within about one turn of the knob. In tuning the reject, should I be looking for that pattern while moving the rexolite over an inch of travel, a half-inch, two inches or ? So my question is not how to tune it but as I tune it, how much should I expect to have to move the rexolite rods to notice the "not good good not good" pattern? Or will it even be there? I suppose the question is only to those who have tuned a wp-639 for a standard 600kc split. Someone who hasn't tuned a `639 will be basing their answer on a comparison to something they have tuned, which may not be all that comparable. For the sake of brevity I won't post the method I used to tune it unless someone wants to know it. Again, thanks to those who answered earlier and thanks in advance any who answer this. rj
