Hi Larry,
PowerSDR 2.2.9 has a special feature that Doug put in to ensure that the 
MIC is available even if you are in Digital SSTV modes where you want to 
send via VAC and then talk.

Take a look at your SETUP --> Audio --> VAC1 middle of the window at 
bottom is a check box that says "Allow PTT to override /Bypass VAC for 
Phone" and it should work FB for you.

I use my space bar to PTT when I am using my MIC and VAC together for 
EasyPal digital SSTV.

could this possible be a solution to your problem?
