The only failure of the wemng on my sidewas Ron's Europawhich could not be persuadedto talk to my BSX and we could not figure out the correct settingsfor his Tiny 2 inthe limited time we had SorryRon. On the other sideof the room things were also moving along nicely and I ran acrossseveralfolk making strangenoiseson 2m into a dummy load.
