Well... The crystal could easily be the problem. Group member Sal sent me a Uniden ARU-251 Repeater to re-crystal and align.
The crystal was cut on the wrong mode and a real cluster $#*& to the problem sort out. The transmitter would partially align but not remain stable. The sanity check was the repeater arrived known operational (on the original frequency) and I had spare Uniden Repeater crystals in the shop. I was able to confirm the wrong mode xtal by using the trusty (and great dollar value as often found on Ebay) crystal check function built into a Sencor FC-71 frequency counter. [if you haven't got a great frequency counter... get a working Sencore FC-71 off Ebay. It's a sleeper deal of the day] I had Bomar cut new crystals in the right mode and after install and alignment the transmitter performed exactly as it should. I traced the wrong crystal mode/operation problem back to a typo which the original xtal order was placed. I/we just put it down to experience. s. > Kevin Custer <[EMAIL PROTECTED]> wrote: > I wouldn't think so, the crystal itself is not 'modulated'; it's the > following active stage that provides the modulation. > Kevin > > > Joe wrote: > > I'm thinking that I might just have a bad crystal, but have > > no way to prove it.
