I need to knuckle down now and figure this out and get transmit working. not to mention reducing the rats nest of cables.

This is nice for reducing interference, eliminating isolators and ferrites on the cabling if your wondering why I am bothering.

Since DM780 worked so well on receive I think I can at least be rid of the hardwires to the MB1. The goal here is to see if VBAN can replace the hardwires and at least one of the DAWs (transmit) using some of the other cool VB Audio software. You have to configure Windows Media Player to use the Virtual Audio Cable as the default audio. There is no need to touch any of the settings at the VAC control panel. You can verify this at the Virtual Audio Cable Control Panel. By default Virtual Audio Cable already creates 1 virtual cable. One DAW for Transmit and one for Receive, both enabled with some very cool VST plugins (some were capable of advanced noise reduction - others were handy in providing scopes and EQs to shape send and receive audio). Download and install Virtual Audio Cable. On my old Anan rig I used to process the audio via two separate DAWs on Hamizilla with great success. VB Audio also has a lot of other interesting software with possibilities. I also need to look at the MB1 CPU while using Full Duplex to get an idea of worse case CPU usage. I will have to work a bit more to get DM780 Audio from Hamzilla back to the MB1 to transmit. I was also able to get DM780 to receive audio from the MB1 and use it to decode messages. It has a way to adjust the latency so I was able to get both to play in sync on both the send and the receive device. So far I have had Audacity play an MP3 both ways, from the MB1 to Hamzilla and Hamizilla back to the MB1. Lol, these claim they are simple, but they do seem a little trick trying to mesh them with the MB1. VB Cable has some free Virtual Audio Cables, one option is with VBAN which lets you a virtual audio cable communicate in Near Real Time to another cable on another PC.
