[CQ-Contest] Dunestar mod. 600 insertion rf loss

[Dave Hachadorian]

I have two Dunestar 600's, and they both show about 80
watts out with 100 watts in. The amplifier draws noticeably
less plate current with the filters in line. I know it's less
than -1 dB, but every little loss hurts, especially
psychologically.
