[hpsdr] Hermes Connectors

Tue Oct 30 06:12:29 PDT 2012

I will do some eyeball tracing to sketch out a cable that could go to Alex or a breakout box with speaker and PTT Out connections along with a DB25 connector for Alex. We should plan on adding this to Hermes doc's. Another idea is 2 connectors,  DB25 and 26 pin, with stiff wire ala gender changer construction to at least get a convenient connector for Alex (or Hercules). I like the breakout box as you can have access to speaker and other signals via unique connectors for later use. Possibly a small PC board with headers mounted in small hammond box.
