Sst I believe the Heathkit SB-1000 QSK board is similar and I have stored
Sst copies of it over on http://sonic.ucdavis.edu
Sst Look on the amateur radio page.

Yes, I know and already download sch of Heathkit SBA-2001-1, but it seems to
me QSK-5 is not a full copy of Heathkit. PIN diodes is not similar, Heathkit
has LM324, Ameritron - no. I would like to get exact copy of Ameritron sch.

Best regards,
