[hpsdr] How to get WSPR working via VAC?

[Dan Babcock]

Ben,

Also, Version 4.10 does not work with PowerSDR.  Use Version 4.09.

A group of Flexradio users have put together an excellent wiki page that 
explains how to interface many digital programs to PowerSDR.  It was written to 
support the Flex 1500, 3000 and 5000 but most of the instructions are applicable 
to the HPSDR versions of PowerSDR.

It can be found at http://flexradiowiki.com/

73,

Dan N4XWE

 VAC trial versions can't be used for any SDR.  The program speaks by     itself 
(Test...Test...Test...) so it interferes with your reception     and even with 
the transmission.
