thanks a lot bay,appreciate it.
here in south africa things are different,we compete under iasca,we dont have all the wonderful associations like your'll do.
in my class im only allowed to use 1 battery, thats in the engine bay,1 amp,1 lenght off 0 gauge cable + / 1 lenght 0 gauge -,
we only allowed 2 4"aeroports.
so the higher the frequency the better for us,not enough battery power to hit the meter with low frequencies unfortunately.
