Thanks for your reply.
With regard to bandwidth I would imagine that we all use more data on a daily basis then it would take to record the position data.
When you consider we use mobiles for email, text, video etc.
The CVR would take more but it's minimal compared to gigantic servers used for YouTube ec.
I guess it would be annoying if false alarms were continually pinging in the ATC towers but I'm sure this could be managed some other way without the disturbance.
And if it is a rarity that a transponder has to be switched off then the problem wouldn't be that big.
I just feel that there is a better way to keep track of the data they so desperately need when a plane goes down.
