Yes, you can use gold sticker equipment with no problem. Be sure however to check that the receiver is narrow band as well.

I was not flying when all this stuff happened. I think people may have gone gold sticker crazy. I have a 7U TX that has a gold sticker. If you read the FAQ, Futaba sez all FM transmitters were narrow band. I see no reason for the sticker to be there.

Down past the TX stuff is a list of narrow band RX
