CNN-fn is owned by Turner Broadcasting. They are pulling the plug, not Voom. That frees up an SD channel in the encoder. That's where Sunshine will be placed. So, no new bandwidth is needed. Voom channel number is unknown at this time.
Don't bother. The new antennas are not finished and the new transmitter shelter doesn't even have AC power to it yet. Voom is not transmitting anything to rainbow 2 and it probably be about 2-3 months before any testing is done.
