@DTelegrafo @EA1CS Good idea. I was not aware that they are listed.

Setting up an antenna close to the waterline has a big performance advantage. The radio waves bounce between the sky and the salty water until they reach the other side of the globe.

This never stops amazing me.

I tried with a reflector and got S9 in Japan, 11000km with 5W.

... sorry .... but my son brought that thing from school and asked me if I knew how to play .... Yes, I said.

Have a nice weekend all.

@cqde_wf4v @mwfoutch1 I use a i5-9500 3GHz with 6 cores.
It is just good enough for 2 RSPduo (4 receivers), 4 skimmers (CW skimmer Afreet) and the aggregator.
I had to switch off whatever windows does not need, like realtime virus check. Now it is stable at 80% CPU usage.

[5Z4GO @5Z4GO]

My RBN CW skimmers. 3 x RSPduo to skim on 6 bands and one Web888 to receive WSPR signals on 8 bands.

@AboveWeston From the antenna to an active isolating splitter (AliExpress:

Then the four outputs each to a passive resistor splitter. (AliExpress:
https://t.co/FTou9wSP1I).
Then to the antenna inputs. Like this you keep it all 50ohms.

Nope. Mine is just running out of the box without any offset

Very nice gadget.

It is a WSPR transmitter. Power-on and it starts immediately sending WSPR signals. It found my KI96 locator with the GPS indoor.

Over a serial terminal you send a command to set callsign and frequency.

Then ... voilà... First spot on WSPR net from Reunion.

@SP3RNZ Nope. Mine is just running out of the box

[5Z4GO @5Z4GO]

@ea6yankee 6 receivers. 3 x RSPduo.
The Web888 is for websdr and WSPR

[5Z4GO @5Z4GO]

@cqde_wf4v @mwfoutch1 6 receivers. 3 RSPduo. The Web888 I use as websdr and to monitor WSPR on all bands

[5Z4GO @5Z4GO]

@cqde_wf4v @mwfoutch1 A windows 10 pc. All my other pc are Linux. Unfortunately there is no CW skimmer for Linux.
It is demanding on the pc hardware.

[5Z4GO @5Z4GO]

@rdavies6 I started with the RSPduo and then later added the Web888.
I use the Web888 as a websdr and to monitor the bands on WSPR.

It can't do both, skimming and websdr, that is what I understand. (different firmware)

[5Z4GO @5Z4GO]

@Krismen_ For this configuration 150pF seem to be the optimum

[5Z4GO @5Z4GO]

I got an old Ameritron 811 amp, still waiting for a replacement tube from China. In the meantime I am upgrading my two EFHW.
UNUN 1:56, 3x 240-43 core. Should be good enough for 500W.

Sunday morning RSK (Radio Society Kenya) net on 7090kHz. This time portable and QRP from Mombasa beach.

[5Z4GO @5Z4GO]

👆🏻What a great idea.
This Greek OM (Dimitris SV8ANW) seems to record every QSO and then sends the link together with the QSL card by email.
Kind of a new age QSL.

I guess he automated that somehow. Will find out and copy paste.

WSPRnet went offline this morning ... The last spot of my beacon was 05:38UTC. Looks like it will be down for a week or so.
