Hello to the group, If anyone needs a readable schematic of the TR4 I have three spare 11 x 17's. You almost hate to fold them. Thanks to Roger at R and L in Cincinnati. They had a unit with a manual. (no affiliation) In the manual was one unusual piece of information and a schematic, unusual to me anyway, a Drake model FF-1 Fixed Frequency Adapter which mounts under the TR-4 and plugs into the VFO connector. In all of my time wandering around flea markets (mainly Dayton) I had never seen nor heard of one. Carl Hibbard WD8NHK [EMAIL PROTECTED] (mailto:[EMAIL PROTECTED])
