"I have a 4SQRPometer that I built several years ago. it initially worked then it started acting strange. I put it aside and forgot about it until recently when I stumbled across it. I'm guessing it has a cold solder joint or something. Anyway I have no need for it so if someone can use it for parts or to repair. Drop me an email. make me an offer. I'll consider almost anything beyond shipping!"
