Hi Bob,

Please post a photo of the usb interface and all the cables that you received with your AFPD so that I can verify if you have the correct items for your DX7. Please also tell me what is the exact error message you're getting.

The wireless AFPD system (AWC) is only for 72 or 36MHz PCM/FM transmitters only. It is not compatible with 2.4Ghz systems like Spektrum and FASST. It will not work with your DX7.

Do not worry on the support as a new and strong distributor has been confirmed for the USA just last week. An announcement will be made soon. In the meantime, if you have any problems, do not hesitate to let me know so that I can offer you a solution.
