[amsat-bb] Unable to even call cq on CAS-6

[Scott]

Here is a screen shot of my RX waterfall showing the pattern of CAS-6's
downlink... it's a challenge to say the least, but at least if you know the
pattern it's possible to TX at just the right time.

... I have to confess that if this pattern of extremely brief operational
windows continues, I'm going to be awfully tempted to see if anyone would
like to try some satellite MSK144.  But I know it's early and hopefully the
situation will improve for voice comms.
