I read in another thread which was closed that a "hardware" update had been made to the TM-7. I bought mine last August and have used it with 5 different receivers without any problems but I sent to the Futaba Servicenter to be checked and it was returned with the message that it had a unique ID and was ok. There was no mention of a hardware update.

Does the Servicenter update the TM-7 if one is not requested or do they just check to see that it is uniquely coded?
