Re: [amsat-bb] RUDAK testing - help please

We also have a problem in the UK with trying to work Japan etc due to the
'off' period between 28-60
It means starting around 2.00hz BST and then trying to stay awake until the
beacon comes back on again around dawn Hi!

substantially.

I want to work Rolf in Micronesia, and the only windows I have are during
the RUDAK time period.
