[KokomoHams] 910 Repeater Update

[K9GTJ]

Another evening of working on the new 910 repeater by Doug, John, and myself. I'm sure you heard me on the repeater testing and dead keying it.  Fun!

After time spent tuning the duplexer cavities, we really thought we had it right but the problem persisted. It turns out one of the new cables made yesterday was the issue.  Once we replaced it, we couldn't make system fail.  

The good news is we learned more about the duplexer on the 910.  These are home built from a July 1972 QST article.  Rather sophisticated to build. 

For now, let keep our fingers crossed the 910 is working.  There are a few finishing tweaks get things completed but for now it seems we found our gremlin.  

One last thing, we look to have someone here on Saturday to look at all the duplexers for our repeaters.  You may find a repeater off the air for a few on Saturday.
