That's still not cut-and-dried if out-of-band can vary among countries. The only alternative would be for Hans to offer specific 328 chips for each country for each band. That's a train just begging to leave the rails. I say this because, last I talked with Hans, he was down to less than 10 bytes of free memory.

Seems that all that is needed is for the QCX to inhibit keying for out-of-band 

frequencies.  This would leave it still able to listen to out-of-band stations.

Not sure there is sufficient program space go support this and it varies by location.

For sure about sufficient space!  I've developed firmware and am painfully award of the challenges trying to "shoe horn" additional features into very limited space. 

Even a range check that looks for reasonable (course) values for the band without following the specific regional band plan would be a help.  Right now, I threw my QCX into a sputtering fit by entering "70201" instead of "7020" in N1MM+. ☺︎
