RX AUDIO mixing between two 6600Ms

[Tyler Stewart]

I'm currently using the A slice of two 6600M and a Microham U2r for the SO2R switching.

Is there a way to set up SDC to do the SO2R audio switching between the two radios.  It seems to have all sorts of built mixers for audio, but I dont seem to be able to get them to switch properly between the two.

Everything else seems to be OK and I'm anxious to try it out in a CWT or maybe WPX if I get over this one last hurdle!  Ultimately I'd like to run 4 bands at once on the two radios, but I'm not quite there yet on the RF side!  LOL

Tyler, you can connect any number of transceivers to the SDC and open as many New QSO windows as you like. For two Flex-6600s, you can have up to 8 New QSO windows and the same number of skimmers. The SDC-RIG Audio system is available for audio integration and control.
See the following sections of the manual:

- Contest > Audio.

- Contest > SOxR.

- RIG Audio

You’ll be able to take full advantage of the SDC sound system’s capabilities when using the RIG Audio system. For example, "SHIFT" function can shift the sound frequency up or down to improve a single operator’s ability to handle multiple rigs/slices simultaneously. RIG Audio will provide you with higher sound quality in SOxR/xBSIQ mode.

Does SDC still work with 3.7.4 firmware?  It doesnt seem to be generating any spots today

3.7.4 seems tp be the only firmware that will safely runon my M model 6600s.  I wont take this last M forward since you cant go backwards to 3.7.4 from version 4s.

I've got two 6600Ms in Austin now...we'll see what they come up with.  I'm still trying to move forward with SDC contest, but there are too many  variables right now.

It should work.
