Hi Pete
Glad to hear the DXE connectors are working FB.
I hope to hear you on the air.

Tim, don't misunderstand. I was not complaining, nor was I doubting
that there is something in these connectors that is new - though I don't
know how to find the patent number. When I saw you on Saturday, I was
assuming that my problem was in the cable itself, Davis RF Ultraflex.
Only today did I discover that the problem was in the connector they
supplied. I replaced it with one of yours, and everything seems fine.
