Hi,
Drifting out of spec xtals are typical, Ive had to do the same on others boards as well. This is good input for others trying to fix their FT301s, thanks. There is a company in the Netherlands that has most of the xtals in the 301, Ive purchased a few resurrecting other 301s. CW and SSB filters drift as well since they have xtals inside that have drifted. These filters can be reworked and xtals replaced.
