Does the meter read about the same plate current as on the > other bands, or is it considerably less? 320ma yeilds 70 watts or so on 10 meters and 20 meters - the differance is that I can get more current and power on the lower bands. on 10m, 320 ma is all she'll produce.

Or does maximum output power require that > you adjust the PLATE control "out" of the dip? It almost peaks with the dip - it's real close but if I turn the PLATE control just a hair CCW past the dip point I get another 10%. > Is the transmitter properly aligned? > > The final tubes may be getting "soft". Weak final tubes exhibit low > output power first on the highest bands. > > 73, Garey - K4OAH > Glen Allen, VA _________________________________________________________________ Don't get caught with egg on your face.
