Hi Bob,

Maybe you know there are soundcards sampling at 192 kS/s, which are able 
to generate frequencies of 0...96 kHz. If you can find such a soundcard, 
you could use that directly to generate your TX frequency, which would 
be much more stable then. And when using SpecLab you can even generate 
DFCW-90 (or 120...), and WSPR-15 or even slow hell :-)
Maybe, if you plan to continuously improve the performance of your 
station, this would be a helpful device/advice :-)
