Back home to FN42. Today I took the eggbeater, preamp, and power supply
outside, along with my Kenwood F6A handheld. There was a pass that went
directly overhead. BLAM! I got a nice signal (albeit with deep fades)
essentially the entire time that the bird was above 10 degrees. (I think it
was from about 8 to about 11, but my Keps may have been a bit old). I tried
turning the preamp on and off during this time to see if it helped. Yep!
Cool! So now I know that
1) The preamp is really helpful on the horizons but by the time the bird is
high in the sky, it makes no difference at all.
2) The eggbeater is better than a rubber ducky, although doubtless not as
good as a beam.
3) I have a reasonable chance of reading a signal even on a fairly low pass
4) Most disappointing: It appears that I really can't receive well with the
antenna inside. I'm going to try again, but that is the biggest difference
I see between failure and success. Disappointing because I really wanted to
keep the antennas inside to avoid any number of aesthetic and safety
Next step: Try to get an SSTV picture out of what I recorded.
Why did I wait so long to start doing this stuff! I planned to be a ham for
something like 50 years, but never did till now!
