Hi Eddie,

I see you can even see me in 424 uHz. You must have a very good antenna design ;-)
I'm also impressed by your results over that 742 km path, http://no.nonsense.ee/qth/map.html?qth=IO92NG&from=JN49IK00


Now, time for a next message! I'm still trying to pass more characters than 7 to the path to Moscow. Hopefully the will be some more OMs joining in.
Let's try 8, again:

f = 8270.100000 Hz
Start time: Saturday 04.Mar.2017   18:00:00
Symbol period: 30 s
Characters: 8
CRC bits: 16
Coding 16K21A
Duration: 11h, 12m, 0s
Antenna current: 700 mA

The signal is more stable, sharper now, see attachments (spectrograms with equal brightness/contrast settings). It has shown 1 dB stronger at IK1QFK in the morning. But probably that was propagation.
The wx forecast announces some rain. Hopefully it won't trigger the safety limit which is set to - 30 mA.

Reports welcome.


73, Stefan

Hi Eddie, your grabber looks fine now, showing good traces from DK7FC.

Yes indeed, after a computer restart the Grabs were still there, timed when I crashed the computer, and they updated.
I have disabled uploads from the new blank SpecLab instances so the present ones will remain for a time.


BTW Last week I've migrated all my lazily-made Dropbox\Public grabbers to "proper" FTP uploads to the DARC server. Now considering withdrawing from Drpbox alltogether.

:-):-) I am following in your footsteps, although I am / was going to try FTP uploads from the Dropbox folder, in this way I would have a remote view from another computer of the Captures on the shack machine. Experimenting with a simple / lazy Grabber.
