There were a number of active WSPR-15 stations on LF last night and
this morning, up to now, including N1BUG getting TA decodes. Well done.
I see most stations are reporting with times stamps xx:15 and xx:45 for
messages which began at xx:00 and xx:30. So the 'old' WSPR-X program
seems to be used by them.
Who of them uses the latest wsprd.exe and the latest dlls together with
the old GUI, as suggested by Domenico?
If this method actually works for everyone, then it may be easier to
set up for most OMs, so all the necessary files could be packed into a
zip file and made available for everyone...

Hi LF,
I want suggest a further way to try WSPR-15 with latest
improvement of the WSJT-X vers. 2.0.0.
WSJT-X uses the program wsprd.exe to decode wspr-2. This program
has also wspr-15 capability. So i have taken wsprd.exe dated 10/11/2018
included in WSJT-X bin folder and putted in the WSPR-X v0.9r3058
directory that i hold in my radio pc since years.
Some dll's need also to be copied in the same way (i did this in
the past, so i'm not sure which files are necessary, but any error's
message explains which library is necessary !)
So the program WSPR-X is now running with a new version of
wsprd.exe and seems stable. I can operate WSPR-15.
By the way, my radio PC is an old PC with WinXp, so i don't
know if this old program (WSPR-X) should work on 64 bit pc.
Also i don't know if this program is longer available in the net.
Maybe this advice can be useful for operators working with
similar conditions of mine.

Hi
Stefan,
here is an attempt for a wspr-15 to wspr-2 receive converter which
should also work under 64-bit Windows versions. Operation is similar to
the old wspr-8 and -32 utilities
http://df6nm.bplaced.net/wspr/slowWSPR.zip
which also contains a description worth reading. The "waitraster"
program has been replaced by a DOS loop based on the %time% variable.
The speeded-up audio should be routed from sndoutpt to WSJT-X using a
virtual audio cable, e.g. VAC or VB-Cable from Vincent Burel
https://www.vb-audio.com/Cable/
This needs to be selected as the default audio output device, as well
as the WSJT-X input device.
Note that
- reported frequencies will be translated from 137600-137625 to
137400-137600 Hz,
- reported timestamps will be 15 or 16 minutes late,
- reported SNR will be 9 dB too good.
I have to admit that the script hasn't been tested yet, so there is no
guarantee that it will work at all. If I was to do this again, I'd
probably not go down the speeded-up audio route, but rather make a
script which calls wsprd.exe directly.
Good luck,
Markus (DF6NM)

Hi Markus,
Congrats to last nights successes!
Well, since WSPR-15 is certainly the better mode for LF DX, and the
WSPR team is not interested in LF, will you find the motivation to
release an updated version of your utilities that enable 64-bit users
to receive WSPR-15 using the latest WSPR-2 decoder?

yes that is the problem. These "tools" are just a simple DOS script.
All the real work is done by the audio utilities from Wolfgang DL4YHF,
which are running fine as ever. But my little "waitraster.exe" utility,
which did nothing but hold the script until the beginning of a desired
minute, will no longer work under Win-64.
Best 73,
Markus

I am interested in this too, but if I
recall there was a reason I
didn't install those tools. I can't remember now... maybe they don't
work on 64 bit machines? If that was it, I am out of luck.
My WSPR2/WSPR15 transmitting tests last season showed that WSPR15
was much better than WSPR2... even though most WSPR2 listeners were
using the new improved decoder and WSPR15 listeners were using the
old WSPR-X.
