Hello Paul,

I am surprised you have had issues with WSPR-X and WSPR15 I often
forget I have it running in tandem with WSPR2 on WSJT-X and it is
still sound and solid after a few days. PC is Windows 7 pro 64 bit.
But it was also fine on Windows XP which I still run on another PC and
on a laptop. The developers were very none receptive to adding WSPR15
to WSJT-X :( I keep trying to get over to Maine most nights, but
conditions  or  Lady Luck have not obliged so far. There don't seem to
be  THAT  many  more  US stations on LF after the licence change, I was
expecting  far  more  to  be  honest.  Good  luck  Paul, don't let Mr.
Beveredge down :)
