I would like to recommend an update of the latest QO-100 band plan, regarding the WB transponder, in the WIDE & NARROW DATV portion.
To avoid wasting precious space, or even disturbing the beacon, the center frequencies for 1.5M 2M channels should be specified.
Those indicated for 1M, 1.5M and 2M are only suitable for 1M channels.
For 1.5M & 2M, only two possible channels should be indicated.
If the frequencies indicated by the band plan are used to transmit at 2M or 1.5M, and in particular for CH No 1, at 10493.25 MHz it is transmitted to the beacon, causing disturbance.
If you transmit at 2M, on CH No 2, at 10494.750 MHz, all three 1M channels are occupied, while only 2 could be occupied by moving to the right of the WIDE & NARROW DATV, leaving a 1M CH 1 free.
If you transmit at 2M on CH 3 at 10496.25 MHz, the NARROW DATV portion is invaded.
