I've been testing a little 25W GW3UEP Class-E transmitter for the past few
weeks and have just completed some observations of its performance at QRSS
speeds, using the VA7JX 630m grabber. I'm pretty surprised at how stable
the
xtal controlled signal is at the faster QRSS speeds and is even useable at
QRSS60 although somewhat chirpy by then. I decided to let the tx run all
night at QRSS60 and any reception reports would be very appreciated.
It is sending "SL" into my large 170' inverted L.
I think it's close to 475.044 and Jack's grabber is showing 475.0477 so it's
probably somewhere in between :-) The grabber, and the chirp, can be seen
here:

Really not too terrible for an HC-49 crystal costing 51 cents!
