Time to measurements. Gain and consumption looks pretty well at quick measures but still we need to measure NF in a better setup/equipment.
Keep tune for updates!

@will_whang SLVS to CSI bridge? Or just direct connection?

[Jorge De Castro | EA1FWI @ThePCBDesigner]

@WD5GRW 😭😭😭 then next time.
Anyway, enjoy your trip and hope to heard you soon on sats!

[Pablo T. @controlpaths]

Today is time for some DSP with RedPitaya STEMlab PRO gen2

[Jorge De Castro | EA1FWI @ThePCBDesigner]

@WD5GRW That’s the mutual passes for EL95 to IN72. Let me know what it fits better for you. 15/06, 18/06 and 19/06 I think they are the best options for both.

Fun with radio... TNX @W7Bmd for JO97 SSB QSO on the last pass! FT-817 as TX & iRadio UV-98PLUS as RX, entire JO97 downlink set as memory channels in SSB, using 100 Hz steps as I would on other radios for RX (TH-D75, IC-R30). Speaker/mic provides 3.5mm jack for RX audio.

Just worked @LA9XGA /P JP51CA on #RS44, very low pass (-0.4 degrees during qso) and booming signal. Thank you Tor for another new grid.

[Jorge De Castro | EA1FWI @ThePCBDesigner]

@LA9XGA Not shared footprint for JP51 yesterday. Hope to have a chance in the future!

[satelliterover @LA9XGA]

@ThePCBDesigner Yes, It's so fun to be back on the satellites as a Rover station. SOTA and satellite is a great combination. Thanks for a new and great contact 73s Tor

[Jorge De Castro | EA1FWI @ThePCBDesigner]

@LA9XGA Many thanks for that fantastic QSOs! This beginning to be funny! 😄 Thanks for the enjoyment Tor!

1- A friend recently handed me this Vivaldi antenna for characterization and VSWR measurements across the 2.4 GHz ISM band.

The antenna was purchased from AliExpress, with no manufacturer or part identification available.

If you still need Morocco on LEO, CN8UN Bernard has been quite active lately. Yesterday (2026-06-07) I wkd him at 18:57z on SO-50, and a little later at 19:16z on FO-29. We had QSOs on RS-44 before. Bernard confirms LOTW very quickly (QSOs from yesterday already confirmed).

Ionospheric conditions were a tad south of ideal, but I got to spend my morning in the radio room of a WW II battle wagon.

Now to head home and see if I can work 15 ships for Museum Ships Weekend.
