[hpsdr] VAC anomaly on RX2

[Ronald Cox]

Warren.
I have been running your version 2/15/13 of the RX2 code for a while and now I fid that the VAC output is very weak and any other program such as FLDIGI can not display the waterfall using the VAC output produced by the program. When I go back and use your latest mRX single RX PowerSDR program, the waterfall it feeds to other programs via VAC works very well as it always did. Any idea what could be wrong?
