Revised QO-100 DATV Bandplan - Please Read

Perhaps - but add an A or B for the 125 kHz - e.g 25A and 25B

Not directly related to the channel numbers, but just looking at the blocks in the image. I have to ask why there are not 2 125KHz in a 333 channel, why the offset?

Is it because at the top end, the roll off of the transponder at 10499.5 would render a narrow transmission unusable at that end?

If someone uses channel 32 for a narrow transmission they have effectively blocked channels 31 and 33 for 500 to 250KS. If using channel 33 for 500 to 250 they have taken up 3 narrow channels. Not a criticism just wishing to understand the logic behind it.

I think Dave has tried to offset the channels so the centre frequencies align for every other channel. By putting the 125 in the gap you can actually have both 333s active and the channel in between without too much degradation. Even better with 2x 250kHz.

While i'm updating the bandplan for the QuickTune software i was having a think too..
I'm adding a tooltip to show up/downlink freqs for each 'channel' when you hover over the bandplan.

How about:
1A,2A,3A for the 1MS...
1-14B for the 333Ks
1-27C for the 125Ks

You can then add more letters for different SR Channels.
