I have found several errors in Linrad01-00. If the fft1 size is small
the timing will become incorrect, help texts do not work under
some circumstances and some other things I no longer remember.
I am writing #5 in the QEX series of articles and I have added a new
parameter "Sellim maxlevel" to allow a different compromise between
maximum pulse power that can be handeled and the compression of strong
signals. (For EME it is useless, that is how it was optimised already)
The 01-01 version will also be a "test release".
