http://w7zoi.net/filters/9megxfils.pdf WebThe crystal filters are 5645 at 50 ohms. For this reason, you can't put in the R4C first IF crystal filter into a TR7 for an AM filter. It would of been so nice if the TR7 etc took R4C crystal filters, but noooooooo. It looks like this was purposely done in the TR7.
