Perhaps the receive crystal was changed without having the channel element temperature compensated with it...?

I do recall yrs ago having a Micor in the trunk in the Cold Winters around N/W Indiana it sounded off Freq, but after a Few Min of Transmitting it Warmed up and sounded Great and Again I am talking about the receive , I think I will temporally put a 100Watt light in the 4 ft cabinet and see if I still have the Problem Only a temporary fix. Find the real problem. A properly tuned radio of this vintage with no other problems will NOT exhibit the behavior you're describing. The one in your trunk unfortunately was also not being maintained properly, either... making you think this is a normal thing for Micor's. I respectfully submit that I know a heck of a lot more about MASTR II's than I do about Micor's, but even with that in mind... It's not normal behavior. Something's still wrong. If the light bulb fixes it, at least you'll know it's temperature-related, and can easily take it to a workbench or on-site start spraying things with cold spray to find the real problem. Nate WY0X
