i don’t know much about this, not my forte. I would like the Bluetooth to be better. The receiver is located in a different room and it cuts out with my Bluetooth headphones. I would only use the receiver to transmit, never to transmit to the 483. It has an antenna, but I can find out if that tiny antenna is on for the WiFi. I’ve scoured the manual and I’ve contacted Yamaha. Anyone know another avenue to try?
