I have been working with electronics for over 50 years and have been very successful. I just installed the ERF-2030 modification in a Galaxy DX-949 and I am disappointed with the results. what was promised and the results are far apart.
Here is the chart from cbtricks under the MOSFET experimenter section.
2SC1969:
25.615 - deadkey = 8.5 watts - 28 watts peak
26.965 - deadkey = 9.0 watts - 31 watts peak
27.865 - deadkey = 9.0 watts - 30 watts peak
ERF2030:
25.615 - deadkey = 8.3 watts - 38 watts peak
26.965 - deadkey = 9.5 watts - 43 watts peak
27.865 - deadkey = 9.4 watts - 40 watts peak
The highest peak I have seen is about 14 watts with a dead maximum of 6 watts.
Has anybody else had similar results?
