Even if the manufacturers don't provide a way to lockout unwanted portions of the band, contest software could help out.   

An example would be to set the contest software to only allow moving the radio's TX frequency from 21200 to 21450, then if  PJ2T is spotted on 21150 in the SSB weekend, it could prevent you from calling, or at least warn you when you select the spot.

One problem with the band map and need QSO/mult windows in CT is that they do not display the TX frequency if they are different than the RX freq.

Don't some cluster software programs let you specify a range of frequencies to filter (in or out)?  That might be another way to handle it.

It'd still be easiest if the radio itself could be set up to prevent TX out of band mistakes.
