Re: LF: W and G

Hi Mal,

if Alberto is right and the W&G 12 really has an IF output in the 10kHz range, it is indeed possible to do the last "demodulation step" completely by software.
In fact, you can use  Spectrum Lab to convert any frequency between 20 Hz and 22(24)kHz into anything you like (with sideband rejection), and filter the downconverted signal to any bandwidth you prefer (thanks to Jim, M0BMU who recently sent me an excellent design procedure for narrow band filters).

Spectrum Lab is currently undergoing "major surgery" to make it capable for stereo processing, so if it's not too urgent you should wait for the next version (V1.7).
