Thanks lazer... well this is strange at the moment I am monitoring frequency PAS10 3764V 2941 3/4 and it is going up and down like a yo-yo...it goes from 1% up to 40%...it is 8:30 am Perth time, I am using a ID Digital sensor 24....whereas frequency 3797V 3003 2/3 it is fine and stable 62% signal quality...
