Has anyone heard of the main dial on the IC-775 freezing for no reason? It began to get tighter during the contest about an hour ago and now it wont turn at all. I tried the screw adjustment but to no avail. 73 fer nw, Bob AD5VJ(AAR6VM) http://www.ad5vj.com/ Member CTDXCC 10X# 37210, FP#-1141 SMIRK#-5177, RARS #-149
