The satgate system was shut down about 2 years ago. The attached posting by
Roy sums it all up. Of course, WB4APR is doing his substantial part in

Edward,
Had a good CW pass at 1430Z. I am using the 35867 object. AOS/LOS were in

John,
A rigblaster is an interface only, but can be used with the correct software
as a TNC for most digital modes. I use MixW which emulates a basic TNC,
including a KISS mode output which works with all the programs I have tried
which expect to see a KISS TNC. There is another program, Packet
