What's the thinking on the Digital Bandwidth signals on Snow Peak? The 434 MHz Input has a 2 MHz Bandwidth and the 1242.00 Bandwidth is listed as 4 MHz.

Hi Mike!
The 434 MHz is 2 MHz B/W due to our crowded bandplan with the 6 MHz range from the 434.0 center frequency (satellite and remote base). The 4 MHz bandwidth at Snow Peak is by choice to reduce the needed bandwidth and to provide "elbow room" for the point to point links from 1246.00 MHz - 1248.00 MHz.
Generally speaking, a digital DVB-T or T2 signal is a continuous signal with the same amplitude throughout the selected bandwidth.
A vestigial sideband signal (analog) uses 3 carriers (video, chroma, and audio) which is not a continuous signal.
In conclusion, we use 2 MHz and 4 MHz (Snow Peak) mainly to reduce bandwidth.
