I am using a cable from HamMadeParts.com that connects to the 6-pin data connector and terminates to a DB-9.? I got all three of my Pi9k6's from etsy.? The jumper is set to 1200 I thought of that last night.? I'm starting to wonder if it is some heavy QRM here from an external source to be honest.? I need to try testing this all at a different location.
