Hi
Mark,
yes, you are producing a nice signal into
Nuernberg. What seems a little odd is that both Nicolas and Roman show it on
502.200 kHz, whereas my reading would be more like 502.225. Give or take a pixel
on the ruler, but my cal shouldn't be that far off...
Reading about wind, moisture and antenna voltage
effects sounds very familiar - my 200 pF on 137 k is definitely a
fair-weather-only type ;-)
Best wishes
Markus, DF6NM
