Thought I would pass this along...... The antenna switching relay for the 756 (Standard, don't know about the later two models) is in stock at Digikey. Omron G5A-237P 12DC is $4.00. Tiny little fellow. Should be fun to change when the UPS guy gets it here. Mine is bad and a buddy across town reports the same. Anybody had trouble with the Pro? Would hope they switched to a heavier part. N0DBX
