Hi John, Dexter and LF group, [email protected]: If anyone wants to inhabit the 135.922 area, Dex and I are available on yes, great, I would surely like to get on the air again. Who else ?? On the receive side, there are perhaps a couple of minor issues about Argo's settings that may be worth considering: - I would probably prefer a lower speed: 90s-slow has the same resolution as 60s-normal, but shows 2.8 hours in a single screenshot (allowing me to doze away for a while without losing downloads ;-)). There is no real loss in temporal resolution as that is anyhow limited by the 10.5mHz bandwidth; the FFT interleave factor (ie number of columns per FFT length) would still be 5.3 instead of 15.9. In my experience, increasing the interleave above about 3 does not show more information, it only makes the noise blobs look wider. - I am usually avoiding the AGC automatic gain setting as it makes it impossible to distinguish between reduced signal and increased noise. Sometimes when dashes are disrupted to a pair of dots, it would help to see whether there is a burst of QRN in the middle. By the way, is John VE1ZJ currently QRV on LF? 73 es kind regards Markus, DF6NM |
