Hi Hans,
Well I suppose if it's possible then that would be a nice addition,
but I'm sure you have better priorities in life ;-)
At this point I'd like to thank you for all the work you have put
in to these little kits.
I've been so busy playing with the U1 and U2 the last 6 month that
I've probably not mentioned my gratitude, or spoken very much to the
XYL - because of all the time I've devoted to building these little
gems !
I am surprised that there is not much written in any major
publications about QRSS and these odd modes. Perhaps we really are
a minority with our experiments.
I've been quite taken by both WSPR and QRSS of late and learnt a lot.
I think QRSS is often seen as poor relation to WSPR, but where else
can you see what looks like a chart recorder of yours and other
signals to compare them by. WSPR doesn't make it easy to compare
the performance of other stations without a lot of to'ing and throwing
about on the WSPR d/base.
QRSS grabbers fit the bill nicely and show up all sorts of other
effects that WSPR could never do. Multipath distortion, ionospheric
oddities, auroras etc.
And then there is on the grabber traces what I call
"ionospheric bend".
Not bending the ionosphere but the bend in the grabber trace
which you see on a stable TX when the ionosphere is changing height
and shifts the incoming signal frequency by about 1Hz.
I see this often on the W4HBK grabber on my signals on 10Mhz.
Fascinating stuff, and I think there is more to come.

Ok well I think I have space for it.
I removed a feature which I have never heard of anyone using which
is the "Inv FSK" feature. Removing that created a little more memory.
