w1tag@charter.net:

If anyone wants to inhabit the 135.922 area, Dex and I are available on
Friday night - Saturday morning. Any takers?

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
