Futaba recievers
What does the dual conversion on the Futaba FP-R127 DF mean? Does that mean it will handle both low and high bands? Or am I way off here?

RE: Futaba recievers
Dual conversion is an interference reduction method. This is overly simplified but better than nothing: Signals are fltered twice versus once (single conversion). Low/High band refers to channel range it's certified for:
Low is 11-35 High is 36-60
Low is 11-35 High is 36-60

RE: Futaba recievers
Dual conversion has nothing to do with shift. It is simply how the receiver detects and handles the rf input. Dual conversion first converts the incomming signal to a lower frequency (12.7 MHZ I think), amplifies it and then converts it again to 455 KHZ where it is once more amplified and decoded. A single conversion receiver just converts the incomming signal to 455 KHZ immediately.
