This was discussed briefly on the AMSAT-BB back in December.  What you are 
hearing is real, but it is not the S1.  It is a harmonic of the S2 created 
by its HELAPS power supply.  Michael Fletcher discussed this in a posting 
on 2001-12-20 after Gunter Wertich asked the same question.  You should 
also be able to hear the upper harmonic at the same offset + the S2 beacon 
freq.  The signal is VERY weak (it is intentionally suppressed!) so hearing 
it is a compliment to your system.
