Dear Gary, Graham, LF Group

Thanks for the screen shots of the Chirped Hell sigs. The "speed" used
during the tests was intended to be viewed with the same spectrogram
settings as QRSS 3

I will be out this evening, but will try some more tests tomorrow. I have
PSK31 working on my shack PC at the moment, plus I have downloaded some RTTY
software which will hopefully be working by then. I'm open to suggestions as
to what sort of tests to do.

BTW Graham - for your preset pots, Farnell part number 452 610 looks like
the right thing.

Cheers, Jim Moritz
