I changed the original designs to be able to use LM358 audio IC amplifier.
(LM358 is one of popular AF AMP IC among many people.)
I think the radio is working very well on the LTspice iV(Liner Technology inc.).
I haven't been able to know who designed for very long months.
I could know W3JDR, Joe in USA designed it on Jun.4, 2016.
I would like to thank you to W3JFR, Joe. .
It is really great job. Many people's long cherished dream came true.
This radio uses well known and popular NE602/SA602/SA612 DBM mixer IC.
( SA602/SA612 model is designed by W3JDR, Joe. Thanks!
