Another disadvantage of PCM is that rx is pretty much radio specific.
Not radio specific but BRAND specific.

A futaba 1024 PCM tx wom't be read by a JR or HiTec PCM rx... or even another futaba rx.
A Futaba 1024 will work with ANY Futaba 1024 RX as long as it's on the same frequency.
It will also work with ANY Futaba FM RX on the same freq as long as you switch the TX to PPM/FM mode. ALL Futaba PCM TX's are capable of this.

With PPM you can grab a JR rx and use a Futaba tx (most of the time) and it'll work fine.
A JR RX will NOT work with a Futaba TX (in the U.S.) unless one or the other is shift selectable. JR has shift select RX's available and the 14MZ Futaba TX is also shift selectable.
