[Lowfer] WSPR decodes so far

[Bill de Carle]

John, JB:

I struggled with WSPRX-15 last night.  It seems like every time I saw 
a nice, strong, easy line from WD2XES on the waterfall display the 
darned thing would refuse to decode it - in spite of always decoding 
the much weaker signal from WH2XRR.  Then another problem came up: it 
would work fine during the 15 minutes a "sure" decode (XES or XRR) 
was forming on the waterfall, then when it actually started to 
decode/upload the result it would just crash and disappear from the 
screen completely, having to be re-started.  I don't believe I 
managed to get even one XES upload completed!  This was during a time 
I was trying to run 2 instances of WSPRX concurrently (in separate 
directories and with separate callsigns) on the same Win-XP 
computer.  I was using a directional antenna (orthogonal loops) on LF 
and an E-probe for MF.  The loops were configured to favor NW <--> 
SE, hoping to see something from XPQ in Wasilla.  No doubt XES and 
XRR were benefiting from the SE lobe.  I even tried running LF and MF 
WSPRX on *separate* computers but it would not decode XES.

Much later, after John's last transmission I re-installed WSPRX and 
ran it on LF-only overnight.  It worked perfectly afterwards, 
decoding and uploading XRR.  Probably while fiddling around with two 
copies (using a virtual audio cable to pipe the output from HDSDR to 
the input of WXPRX) I messed up.  I know WSPR should be able to 
receive I/Q samples directly from an SDR-IQ (no VAC needed) - but I 
sure couldn't figure out how to do that with WSPRX, the only one to 
support WSPR-15.

Thanks for the LF transmissions,
Bill VE2IQ / VE3IQB
