Garry,

Thanks for the WM capture. I have switched the LowFer exciter from the 
U3S to the Arduino Shield from QRPLabs, to be able to run my own custom 
graphic code. I plan to implement a code solution to be able to combine 
both the Hi- and Lo- Fer beacons into the one exciter and antenna 
system. For now the HiFer is still on a separate U3S/antenna.

It appears the frequency is .1 or .2 lower than I was wanting, so I will 
bring it up a touch.

In seeing your capture I can refine the graphics to better fit the QRSS 
30 speed. My local captures look fine, even with the RF signal 
attenuated. I realize now that as I reduce the RF signal, I am also 
reducing the associated noise.  I need to improve my test setup to 
better simulate the DX reception.

Again, thanks for listening.
