So, if a certain oscillator coil does not work as in Figure A due to winding phase issues, it might work if reversed as in Figure B ? I have taken figure A as an example from an actual circuit diagram. Maybe a BC548B or other suitable transistor could be used as the local oscillator ?
Apologies for the poor diagram.
