Re: ZN414 and TA7642 radios
I enjoy experimenting with the TA7642 . The third version I built works mostly fine where I live in the Southampton area. I can tune in from 531 kHz to 1557 kHz, but no further down than that. In London the reception was good in West Drayton, but poor in Southall due to a local transmitter signal being 'smeared' across a large portion of the dial.
I used a 4 inch ferrite rod and MW coil from an old radio to get the best results and a good quality polyvaricon tuning cap.
