Updated W4BXI System Audio Drawing

In an earlier blog posting W4UOA provided a drawing of W4BXI' s overall audio interconnections, and WA5MLF followed with a drawing to focus on the two-way audio paths between transceiver and Internet-connected PC. Since that time W4BXI has added a second audio mixer (colored orange) to the system. An updated draft drawing by WA5MLF is shown below (click to enlarge).

Photos of key hardware elements may be seen here.

Feedback from W4BXI would be appreciated to ensure that this version of the drawing conforms with the "as built" hardware configuration.

This may aid our ongoing discussions of interfacing multiple participants to an HF radio QSO using Skype, and even the 20th century technology called a phone patch. Today's on-air discussion renewed the quest for a system configuration that can connect multiple Skype callers to the host HF transceiver without the use of external hardware mixers or a second PC to host the Skype audio conference.
