My new transmitter arrived and the first thing I noticed is that it needs a micro SD card instead of the standard sized SD card. So I've ordered one and will wait for that to arrive. I suspect that you may be right about the fact that I can't transfer information form one TX to the other. The manual says that the micro SD card needs to be initialized by the TX, so I have a feeling that even though I can do that first on the T12K, when I put that (in the adapter case) into the T12FG it's going to need initializing again...Oh well, one can only dream of a perfect world, even though these are from the same company they still aren't talking to each other...
