Bad news from Swissphone about the "toggling" function. See my mail to them and the answer back to me:

Q:
Is it possible to get the coming BOSS925MK to work on 149.3875Mhz and 149.1125Mhz at the same time?

I´ve heard that it has a toggle/scanfunction so it can receive messages from for an example two frequencies at the same time, but if the messages is sent exactly same time then I will of course miss one of the messages.
Have I understood this correct?

A:
Hello.

the version coming soon enables the channel switching by the user within a band of 1 MHz (selection over the pager's keys). It will NOT enable to receive or scan many channels simultaneously.

I hope you will need this functionality enhancement and I am looking forward to read from you.

Kind regards
