Extension Speaker comparison super test, CB radio, Ham radio, business radio

I got the wholesaler to send every extension speaker they had available....and here I tested them all. Using a 1981 Realistic TRC1001 on it's own telescopic aerial, I plugged in the different speakers so you can hear & see the difference. On the first set of tests, Mr Chippie was 0.5 mile away up the road so we could hear the speakers with a solid signal. He then drove 1.5 miles away so we could hear on a more scratchy signal.
