Hello Jim, VLF,
Jim, actually it is quite easy and logic that multiple instances can be
opened that way. But it took me a long time as well to find that trick,
actually as long as DF6NM told me about it :-)
There are several things to learn and the program can be quite complex
but all in all it is very close to perfect (it can't be perfect without
beeing complex, and complex is relative) and, on VLF, there is no (!)
alternative. I'm still running a quite old version here but recently i
had to use the latest version and actually found some advantages over
the old one. So it even became better :-) Once again many thanks to Wolf
/ DL4YHF that way!
Somehow a pity, i would like to be on air now but it's rainy, a bit. But
i learned that 30 kV rms is not so much for such a big coil and maybe i
should give it a try with some plastic foil coverage.
What about, the xmas days? Is there someone watching, maybe arround the
26th and 27th? I would like to run a longer experiment, maybe 3 days
permanent operation, testing various modes, like OPDS32. Paul Nicholson
told me he will write a tool to decode OPDS in his linux system and i
belive he will decode it!
The QRN is really low on 33km these days, amazing!
73 all

Peter,
Thank you, I had no idea how to run multiple instances of SpecLab, and had
assumed that it could take some time to learn, and that there could be
driver conflicts or memory conflicts. As soon as I read your message I
opened a second instance of SpecLab and enjoyed the show. Running multiple
bandwidths will save so much time; I had been losing time and data by
aborting collection to check a frequency-offset calibration marker at a
higher frame rate (broader bandwidth), or to check adjacent-spectrum noise.
I just opened four windows at different bandwidths and see that I can watch
and manage local noise using one of the windows while searching, monitoring
(and assessing remote interferers) in the other windows. This is a wonderful
tool, thank you for taking the time to help me with it.

Hello Jim,
Or check VLF grabber www.qsl.net/pa1sdb
Did you know that it is easy to start and run several Spectrum Lab sessions
at one PC ?
Just hit the SL start icon again and reconfigure it.
I have here a "Retro" 1000 MHz PC who has 4 SL running for 4x.
The 4 are published at www.qsl.net/pa1sdb grabber.
I commit, that PC does nothing els besides VLF RX.
So why not run a Wideband, 424, 238 and 47 uHz for example :-)

I anyone planning 8.9kHz tests in the near future? I'll have SpecLab
running in the VLF from now on except for upgrades. What is the best
frequency range to monitor? I have been planning to use 47uHz bandwidth.

Hi Eddie,
Yes, maybe this weekend, if the WX permits. I just made some
optimisations to the PA und will do more changes to the system.
I will announce it one day in advance or so.

Hi All
Are there any more 8.9KHz tests planned for the near future. I missed
Stefan's last.
I look forward to any that come up, plenty of warning appreciated please.
