Tuning Tips

 Increasing C4 increases efficiency at the low end of the

band (87.5 MHz), but there is a trade--off in power at the

high end of the band.

 Increasing the length of Coax3 increases efficiency at the

low end of the band (87.5 MHz), but there is a trade off in

efficiency and power at the high end of the band.

 Make sure all the coax are measured tip to tip.

 Increasing C5 increases the power, but lowers efficiency.
