It wouldn't hurt to specify if you are using the stock 9x firmware of one of the available aftermarket ones, such as ER9X etc. Most of us have abandoned the stock firmware for ER9X due to it's extreme flexibility... such as differential programming. Personally, I only used the stock firmware long enough to confirm the radio worked and then I installed er9x and the Frsky hack module, none of which is any help to you if you are running the stock firmware. Perhaps Bruce will chime in as I think he still runs a stock 9x. or two?!?!
