... like before, I am running two instances on the
same WSPRX installation (in c:\Programme\wsprx\ on an XP machine). This seems to
work flawlessly, with -2 and -15 decodes uploaded and interleaved correctly
in ALL_WSPR.TXT. The only surprise was that some .c2 and one .wav
file were left over in the save subdirectory, which is normally not
the case.
Using spearate DDS hardware and control program, I
did a couple of low power transmissions at either speed (not simultaneously
though ;-). Power was about 25 W into my TX Marconi at
half-height, maybe 0.1 W radiated power or so. Well I have to admit
neglecting my QRO duties to novices tonight ;-) But I was just too
lazy to push out the mast, only to pull it in again before leaving to
work tomorrow morning.
All the best,
Markus (DF6NM)

Hi Wolf, Markus !
For testing purposes you could run
WSPR-2-mode twice as well instead of
-15 and -2.
Better use two
installations of WSPR-X into two separate directories
from Root C:\, as WSPR
writes temporary *.wav and *.C2-files to its
"save"-subdirectory (even at
save=none). They are deleted immediately
after decode. Maybe one instance
deletes the file of the concurrent
instance. At WSPR-15 and WSPR-2 both
beginn their cycle at 00:00 and
00:30, so the filenames may be identical,
leaving to confusion. There
will be NO errormessages warning you!
At
the beginning of WSPR-X we learned that whitespace characters in
directory-names as well as local characters (German "Umlaute") are a bad
idea. This has not changed. Best use old-fashioned DOS names like
C:\wspr_2 and C:\wspr_15 or similar. There are no errormessages or
crash, it just will not decode anything. (experience of Stefan DK7FC at
that time)
