Actually, Mike, I think I've seen mention of Datong in recent years. Not totally dead yet. Dr. D. A. Tong was a very clever designer, but he kept his designs very close to his chest. To the best of my knowledge, the schematics for the FL3 or others were never published. I too have an FL3 and would like to see the schematic, but no joy so far. 73, Bob N6WG

Hello Everyone! Just wondering, if, amongst all the expertise & stored info amongst Elecraft list members, anybody has a schematic, or any other info on the Datong FL3 Audio Filter. These were made in England back in the 1980s & I think that Datong is now out of business. Plan on using it with my 2 x K2s (0681 & 2681). Thanks & 73 de Mike, zl1mh. -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
