      Does it hear your BPQ32 node good?

      If so watch between node broadcasts from it when things are idle between you and it. Does the obs counter for LEHIGH on your BPQ32 node stay where it should? Just do a N LEHIGH every minute or two for a bit. Or do you see odd drops (more than 1 down) on the obs counter after a bit...maybe even it disappearing from your BPQ32's nodes list for a minute or two till another broadcast comes in from LEHIGH?

      Like I said previously, if you're not doing locked routes and depending on the broadcasts to keep things correct...you may have the problem and not know it. Occasionally you would be missing a node in the list that should of been there, then minutes later it's back and all seems fine.

      I've also seen it get possessed at times and the obs counter will show a triple digit value like 200 or so (wow). That's rare and I haven't seen it with the latest version of BPQ32.
