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 go=
od 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 s=
ome
hardware to use it with the PC soundcard and 1pps

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

Hi Luis,

Another question: Are you still running your VLF grabber? And are you inter=
ested 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 wh=
atever ferquency, Trying a first message decode from DL > EA could be chall=
enging.

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. B=
ut with my new TX-system this is just fine because a transmssion wouldn't t=
ake much longer than 2 hours anyway.


73, Stefan

Hi LF

Apart from cheking that blacksheep is still running ;-)

Just a notification to LFMEN
I=92m transmitting WSPR-2 during daylight to check conditions as we approac=
h 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=92t 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 EA5D=
OM/2

As conditions get worse during daylight I will switch to WSPR-15 and hope t=
o get somebody reporting there in
the forgotten mode
