Thanks, although I have confess that pulling the 470K I.F to 455 was a bit of struggle doing it by ear when I`d forgotten to connect up the Ground for the tunning coils and could only get a signal with a longwire, seems a longwire can act as a ground to?
half a morning later I discovered the connection that I should have made and didn`t, and it all burst into life perfectly when I completed it.
I was hopping it would pick up off the ferrite rod alone, but only the very strongest stations come through, which turned out to be an advange for tuning and peaking of the audio and signals.
so now it has a Antenna coil on the ferrite rod, and it serves both LW and MW well.
maybe the ECH81 isn`t the best mixer front end to use?
