Hi Mark,

I'm afraid I can't help with the relay, but I am a fan of the YE-ZB 
system.  My presentation *HERE 
<http://www.skywaves.ar88.net/Presentations/YE-ZB%20Presentation.pdf>*.

While we're on the subject, does anyone know what "ZA" was?  Saw a 
reference to it on an aircraft check-list placard.

Good luck with your project.
Al
