differenze tra vecchia e nuova RX R149DP futaba

nel frattempo mi ha risposto la futaba alla quale ho chiesto chiarimenti.
parlano di banda alta e bassa, ma che significa???

di seguito la risposta: Thank you for your recent e-mail.

To identify a newer R149DP from the older ones, remove the crystal and look at the PCB board that is standing up. If there are no traces and solder (just an empty board) it is the new one.

If that is the newer R149DP receiver, it works with both high and low band crystals and replaces the older R149DP receivers on separate high and low bands.

If it is an older R149DP receiver and is not marked as to which channel it is, or if it is not marked with a sticker that says if it is High or Low. You can check inside the crystal slot to see if there is a red mark. If there is a red mark, this indicates that the receiver is High band.

The newer ones have the newest technology in them and will operate better than the older ones...

Immagino che i 72MHz siano intesi come di alta banda mentre i 35/40 come di bassa banda ...
