Someone told me that Channel 8 on AVL58 matched up with Channel C-1 on the Boscam 5802. Low and behold... everyone that has any issues receiving a signal with the boscam 5802 that tunes into Channel 8 on the TX and C-1 on the Rx get results. That being said... according to charts... channel 3 and 4 have the highest wattage and I want to try and use them. I looked up the chart in the AVL58 manual and the channel chart to the Boscam and nothing works! one of them is incorrect but I don't know which! Even the Channel 8 with C-1 doesn't match up.
