[hpsdr] Hpsdr Digest, Vol 137, Issue 4

Fri Jul 7 15:51:26 PDT 2017

Doug, Chris and Warren,

Thanks to all you hard working warriors who make these important and massively effective enhancements.
I run Atlas based Ozy, Penelope and Mercury.  The enhancements over the last two years have transformed my system which has been in constant use since 2009.  The CW improvements in particular will be welcomed by those who love the mode.

Cheers Dean VK5LB.
