I don't know about you guys but I have had a great time using my SoftRock40 to study the band conditions. I have identified all kinds of noise sources within...
Hi Guys, I loaded the Rocky software last night. I was suprised to find that it seemed to make a better receiver with the SoftRock40 than the Flex software. Is...
I know the Delta-44 is the "preferred" sound card by many for SDR use, however I wonder which external card has shown the best performance for use with a...
Now, you really cannot do a fair comparison of Rocky and PowerSDR. The PowerSDR software was developed to support the SDR-1000 which is MUCH more complex than...
Tony, The current version of Rocky is fantastic. Incredible audio quality with the Soundblaster External 24 Bit soundcard and 96khz sample. On that rare...
... John, I think you want to direct the request/question to Alex, not Tony. Tony is the extremely talented designer of the SR40 V1, V2, V3, V4, V5, etc......

Hi Bill, ... Great idea! I will see if I can implement it, though this will certainly take quite a bit of time. I/Q recordings take a lot of disk space. At 96...
