Yes, certainly not the best time in the year, but never mind. We could just try and see. My signal from the ground loop is much stronger than from the INV-L at the institute. So there is a chance. Summer activity, you know...

Hi Stefan, VLF

Yes, I still run the 8270Hz grabber (see almost last screen) https://ea5dom.ure.es/grabber/index.html
But QRM is too high here. I have never been able to detect a signal in that band yet

But can see that the vertical antenna for LF transmission performs quite good in LF and VLF
Opposite to MF, were the noise when it was tuned there was a real hell, so it was ususable for Rx

Would be interesting to check this antenna in 8270Hz. But need to arrange some
hardware to use it with the PC soundcard and 1pps

From 6 to 10 UTC the elevators are intensively used here. Fortunately it seems that the QRM from the motor
variators is not so high at VLF. Let me arrange the Rx side and will be ready for a test

Hi Luis,

Another question: Are you still running your VLF grabber? And are you interested to try to receive an EbNaut message at 8270 Hz (again)?
I have some time here near the TX antenna and like to TX a bit again, on whatever ferquency, Trying a first message decode from DL > EA could be challenging.

Or, if someone else likes to join or suggest something, i'm open for ideas.

There is only a small time window where the QRN is low, about 6...10 UTC. But with my new TX-system this is just fine because a transmssion wouldn't take much longer than 2 hours anyway.

Hi LF

 

Apart from cheking that blacksheep is still running ;-)

 

Just a notification to LFMEN

I’m transmitting WSPR-2 during daylight to check conditions as we approach summer solstice here

About 2,7A RF current normally

 

The PA is still down at home, so switched off at night. But then I can use the 90m vertical for RX

QRM is high but overall is a very good performer. I can report Chris 2E0ILY with nice signals and also others which

unfortunately don’t transmit during best night hours. This reports can be seen spotted as EA5DOM/3

There is a permanent 24/7 Rx using MiniWhip with poorer Rx spotting as EA5DOM/2

 

As conditions get worse during daylight I will switch to WSPR-15 and hope to get somebody reporting there in

the forgotten mode
