Mark,
This is exactly how the system works. I have actually flown a prop aircraft on channel 46 (72mhz) on a Futaba 9Z with another TX on the same channel turned on with sticks moving during the entire flight without a hint of interference and minimal frame loss inccured. Since the Weatronic system tunes to the exact frequency of the TX (when scan mode is performed), slight variation in the frequency transmission is ignored from the second TX unless it happens to be transmitting on the same EXACT frequency (unlikely).

My understanding of the Weatronic device is that it doesn't work on a pre-determinded frequency as such, rather it syncs to the EXACT frequency that your TX emits within the frequency range of the channel you are on, ensuring a 'better' RF link. Now, seeing as the Weatronic always uses the strongest signal from its 2 receivers, does this mean that if someone else 'on my channel' switches on and transmits on this 'same channel' but has a slightly different frequency variation of this channel that I will not get shot down as the Wea will swap to the RX that is receiving the 'stronger' i.e. more accurate (?) received signal from my TX????
