Mike;
Those captures are amazing!  You caught me off guard as I didn't think anyone would see anything for hour or two and my signal generator would stabilize after about an hour!  I didn't get home until after 2300 to warm it up.

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 :-)
