[Lowfer] VO1NA OP32

Thanks for the info on OP32RX. Looks like v1.8.7 is current. What is lowest 
detection level 
you've seen with that?

Roger on the relearn of Spectrum Lab / opds2h6.exe ... same here! Plus my upload stuff all changed since I've 
switched web hosting services a few months back. The first FFT output file 
comes 35 minutes after start ... and then every 10 minutes ... the way things 
are configured here. 35 minutes is a long time to wait to see if 
you've screwed up something. Not as bad as Ebnaut on VLF where the first FFT file takes 6 - 8 hours! Been burned a couple times with that.

Jay, I like the Op32Rx v1.8.7 software.  Perhaps a newer version exists 
but I haven't 
looked. I do sometimes run Opera v1.6.5 but dislike it for 
the reasons you mentioned. Also, it falses more often and 
there's no way 
for you to remove bogus call signs from the deep search list. Nor is 
there a way to specify an arbitrary operating frequency, hence my lowfer 
shows up as if it's 
sending on about 137.5 kHz rather than 185.185 kHz.



 After I saw your note I had to relearn how to run  Spectrum Lab with 
opds2h6.exe. Finally got it going, but too late for VO1NA decodes. The 
very precise FFT takes a LONG time to acquire and I had things set up 
with a number of things that needed changed for 137.477 kHz. By about 
the third try I think I had caught all of them. Then I needed to start 
all over for SIW on 185.185 kHz, hi.

73, Garry, K3SIW
