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!

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.

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.

That’s my first ISS pass (and also sat) from my new QTH since 8 months ago that I’ve moved (same locator) and it has gone really well with only 24 elevation degrees. Kanye thanks to all stations.
