I have been looking for SW receiver circuits or projects since a time but I can not find. Only some circuits of regenerative recivers which I don't need. I will appreciate if any body could recommens where to find superhetrpdyne SW receiver circuits to build.
You will probably find SW receiver circuits in these books:
ARRL Handbook for Radio Communications (aka The Radio Amateur's Handbook) , has been published every year for many decades, any version younger than 1990 or so is fine.
