I remember years ago they worked with me to get a Midland 13-509 crystal correct, took 3 crystals and I only paid for one. I don't know if they still have the same patience with their customers. It turned out to be an error in their paperwork. Look at the various schematics and see if the components match up with what you have on the board. Some components are marked "S.B.T" and I don't remember exactly what that stands for. I think I remember someone at Spectrum telling me that they are optional components that may or may not be used. Does anyone remember exactly what S.B.T stood for? 73, Joe, K1ike George Henry wrote: > Exactly the problem... so far, I have received copies of specs that say 30 > pF, 12 pF, and 8 pF load capacitance.... >
