Thanks andrewn, I haven't done anything further to mine. I think the 6 transistors are an RF amp and an OSC for each band, i have the ta7640ap datasheet and appears that AM/FM is switch on pin 3, but audio quality is so rough that it impossible to tell the difference, hopefully i will tune in to local radio club net on 6M FM GB3WY, i'm going o keep toying with it
