Thankyou very much Stefan. I see you went through much pain to achieve the final result. I know this pain working on older test equipment. I am once again a FT221R owner (for fun on 2m like old days...). Thankyou for sharing your hard won efforts. Excellent video's...73 de M0BTZ

Surprising that the inductor adjustment is not covered in the alignment procedure as it affects the PLL operation significantly. Looking forward to the transmitter alignment. Thank you for sharing your knowledge with us Stefan! Regards, David

I´m sure that there are many "secrets" for aligning which are not published....

The Wadley Lop system was a brilliant piece of RF engineering, thanks to Trevor Lloyd Wadley. I remember when the system was introduced.

Yes, i know too this wadley loop. But here we have NO Wadley loop, it´s a standard PLL.
