Since CW Skimmer attached directly to the I/Q data coming in from the hardware, it is effectively another receiver. However it doesn't receive on just one frequency. It sets up a receiver/decoder anywhere in the spectrum that it finds a signal. In my tests during the ARRL contest, that could be as many as 500 receivers acting at once, automatically copying code from stations as close as about 50hz apart. Use the output of its internal decoder to listen to any station by clicking on it, or have it tune the 5k to that frequency.
This is all working today. 73 Ed W2RF On 21 Feb 2008 at 4:58, Lee A Crocker wrote: > Daydreaming about contesting features is a lot of fun too, like hooking up CW > skimmer to the QSD. > > The F5K has in the present software as I understand it 16 possible watch > receivers.
