[TenTec] Argonaut 509 modifications

[Allen Smith]

For what it's worth I agree with Geoff in wondering if the "509 files" Clark Savage Turner found could be put up on a web page or FTP site.  I've found a few mods online here and there but nothing that comes close to the "...many really good mods and good insights into making that rig work very well."

I have a lovely in appearance 509, looks almost "NIB."  It's a fun rig but suffers from a really bad "pop" on initial key up followed by a bad case of key clicks whenever sending.  Only way to tame the key clicks I've found is to turn the AF gain way down while sending and NOT use headphones.

Has anyone had any success in ridding their 509 of this problem using the modification outlined by W1HUE's "Cleaner Keying for the Ten-Tec 509" article?  Lifting traces and drilling holes in circuit boards is not my idea of fun unless the payoff is really worthwhile.
