[Fourlanders] FT-847 HRD DM780 audio interface question

[Bill Pence]

Ron/Kos/all,
somewhat new data point. the issue seems to be a CAT/HRD related item.
 I unhooked the speaker output and listened to the transmit audio in
DM-780 stand alone and from within HRD. I heard NO level change.

SO, the conclusion is there is some power slider that I have not found
or a CAT command issue.

It will be interesting when I get the Icom 706 CAT cable so I can use
HRD and DM-780 with the IC706 rather than just DM-780.

any idea where the HRD power output adjustment is located???

thanks!!
