t’s no secret that one of my hobbies is ham radio. I’ve got a few projects lying around that I would like to see working. Today while looking for information on refurbishing a Heathkit SB-101 transceiver, I found a website called Heathstuff with lots of useful information related to Heathkit radios. The link is here: http://www.kiyoinc.com/heathstuff.html
Sadly, the pages have not been updated since February 2004. The owner, AH6GI, has a lot of good information here, and I hope it helps you out.
