Tom, Norman, Jim,
thanks for your interesting replies!

Well, with that you *are* an expert compared to me, who has almost no
ideas about radio observation. :-)
What I wanted to say is, that the AMS has been experimenting with radio
equipment for quite a long time. So I guess some of you gained
good experience in this field by now, don't you?

This was my main concern. So far we've seen nothing compared to the real
storm that hopefully occurs next year. To my understanding, Leonids rates
several order of magnitudes higher than in 1997 would produce a kind of
overall ionization of the respective atmospheric layer resulting in
continuous radio reflection. If that happens, it wouldn't help you much to
tune your system to another frequency or so. Here the questions arises,
what you can do to escape saturation.
Best regards, Sirko
