[amsat-bb] JY1-sat dashboard

[Kevin]

Hi Hasan,
    I first noticed this on my original lash up of 
airspy>sdr#>vbcable>dashboard and I was manually tuning and as doppler 
marched the signal through the passband  I learned that moving it back 
up too quickly would lose lock and seemed to have trouble re-locking, so 
I ignored this as being on my end and manual tuning.
   I now have it running on a funcube dongle and still see it, I'm still 
getting a feel for the real downlink and doppler swings so my range may 
be set a little wide, I will try closing it in and see if that helps.

Thanks
Kevin
