Hi all
Any comments.
The powers that be in NZ have decreed that all frequencies above
72.5mHz are no longer to be used here (conflict with R/c cranes, log hawlers and rail shunting engines).I was on 72.550mHz (Ch. 38 US) :-{ In process of moving to 72.250mHz (Ch. 23 US).
JR and FMA brand R/x (maybe others) can be used on any frequency in the 72mHz band. Futaba have Hi and Lo 72mHz R/x and say Hi band R/x with Lo (Ch. 23) crystal are not compatible.
Took all gear to the field and set up a test.
With T/x (aerial down) 30 paces away, tried every compatible combination. T/x module (Ch. 38 and 23 I have both for test), and Futaba R/x (Hi and Lo with R/x crystals for 38 and 23).
Found no problems with Hi R/x with Lo crystal installed.
At about 60 paces between T/x and R/x had jittering of servos with Hi to Hi combination as expected as well as Hi to Lo combinations.
Are Futaba being super cautious about Hi R/x - Lo crystal combinations. Any one regularly swap Hi - Lo crystals in Futaba gear.
