... yes, indeed, it was me, I just had my first Slow-Hell QSO with Fabian,
DJ1YFK who responded in QRSS. 

I used a piece of software written in by Markus, DF6NM in QBASIC. Once set
up it is simple but relatively easy to use. Currently I only have a German
explanation of how to set up the software, but with Markus' permission I
will translate the text and can send you the small software. It consists of
two programs, one that sets up all needed characters in the frequencies
needed and another one that converts those small WAV files into a large one
that is then transmitted through the Windows-Sound player to the soundcard.
This process is automated by a batch-file (.BAT). 

I have also solved the difficulties I had with my SSB transmitter, the
Hagenuk EX-1001. Originally this device delivers about 50 mW on 136 kHz, so
I build a small amplifier (thanks to the idea of OM2TW) using a TDA2030.
This buffer needs approximately 18 Volt, so I used a voltage that was
present in the device. Well, accidently it was the 18 Volt line that also
supplies the temperature compensated crystal oscillator, so I had AM and FM
on my signal. Now I supply the buffer-PA externally and now my signal is
roch stabil! 

So see you in Slow-Hell, PSK08, PSK31 and all the other nice modes you can
generate with an SSB exciter.
