Quite possibly at age 10 I wouldn't have had a clue about what you just 
wrote:-). The TX was screen mod and looking back the match to the amp 
was poor. We just turned it up for max smoke. At the time it sounded OK. 
Got out about a mile, covered the neighborhood, we got free records and 
sold advertsing (2 sponsors). All the kids in the neighborhood got to be 
DJs that summer.
