RE: JR 7202
From the pre-production version I have, it doesnt support the opposition's alternative shift.
It works on the standard RC Bands ie 35 MHz, 72 MHz and I would imagine that for the relevant areas, 36 MHz, 40 MHz, 41 MHz and possibly th 50MHz band. It has digital trims.
When you power up, the set prompts you to confirm the channel number you wish to operate on, otherwise it doesn't transmit. You can change the channel number in the System setup.
