Cobra 139XLR need receive alignment info and/or some mods for receive?

Hi all, I am sure this has been asked before but I have a Cobra 139XLR (D858 chip), receive seems "decent" but it is somewhat noisy and I know I can improve the receive. Can anyone tell me what to align for receive or perhaps some simple mods. I have a signal generator, VTVM, and solder/desolder equipment so any information would be great.

Thanks to all, Adam

Try PM'ing TheCBDoctor, he was the Cobra goto guy on the forum, I bet he has the service manual for it. He came back a couple months ago but haven't seen him recently.
