Hi Brian, Yes, one needs to exercise care that the XTALL board DIP switch is set so that transmission is in the right band for the mode in use. I think it is safer to use the v2.4 code that gives one of 16 center frequency selections. Custom EE values in the XTALL PIC memory could help reduce the possibility of transmission outside of the desired band.

Just to check one point, if a XTALLv1.1 is used with a RXTXv6.2, my understanding is that it increases the number of sub-bands within the two design bands of the chosen RXTXv6.2 but does not make it multi- band. So presumably care should be taken not to TX with the XTALLv1.1 set to a "wrong" band? Is this correct or am I missing something? Many thanks, Brian G3ZOH
