Anyone have a schematic of the KR5 keyer. The back panel has 6 and 12vdc input jacks. I need to know how D11 and D12 (5.6v zener) connect to the ckt. Any help is appreciated. 72, Marv Fagenson, K6HCJ --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html ---
