SR-40 phase check
The PowerSDR program also has a great feature to check the output phase
relationship from the SR-40. It's "PHASE" under the MODE menu. No circle,

Re: Rocky 1.03 is available

Re: Rocky v1.03 msg: Unable to start output to SB Live Wave Device
WOW! Rocky v1.03 works remarkably well. Thanks, Alex.
I decided to quit fighting City Hall by using a non-supported sound
card, and ordered, today, an M-Audio Delta 44.

Re: 7.056Mhz
Hi
It's not a spur at all, its the zero (or dc) part of the spectrum that
