UPDATE: SharkRF Released V63 Beta which has vastly improved the quality of the connection of the OS4 and OS4 Pro on REF035. I contacted Norbert (Tech Support via email) and sent him logs from a conversation between myself and a user with an OS3 and OS4 Pro, showing the issues and differences between the devices.
Although the problem is not 100% corrected, reports are showing that users running V63 Beta have less than 10% loss and typically in the 1, 2 and 3% area of packet loss. The audio is intelligible with some blips and bips here and there, but otherwise usable. Whatever SharkRF has done in V63 Beta, they are heading in the right direction and the OS4's performance is almost that of the OS3 as far as packet loss on our reflector.
Thank you guys! It looks like you have just a few more tweaks of your code to make it 100%
