One successful decode from the "B" SDR IQ receiver and Dell 630
2050 -29 0.9 0.503925 0 SMBHZ JO57 40 (reported as BY3X)
Im definately getting better decodes on the SDR/D630 than the R75/Dell 610. Whether this is a result of the A>D loss which the R75 analogue incurs coming down to audio etc - or a true receiver artifact remains to be seen, but its the same on HF as well - Ill swop them over, or parts of the system and will try to see where the improvement is.
Now I know absolutely know that for my listening pleasure the R75 knocks spots on sensitivity and other filtering/AGC/NB over the SDR IQ - but in a highly processed, right on the edge -29/-30 world, heavy noise environment with plenty of RF perhaps the pure D to D SDR makes that little difference. Or it could really be the processing power and divisors between the two computers....lots of variables here so Im still not sure.
Its was really noisy and surprised to get anything -there is a large Typhoon between Hainan Island and Hong Kong which appears to be the largest noise maker.
