ANTENNAS · RUA window dipole and a metal façadeTwo days of remote SDR measurements: soldering, position, power and readings that drift.

ANTENNASA dipole outside the windowFrom a vertical VHF dipole to a compact 28 MHz antenna.

For my current experiments on 144 MHz, I use a vertical dipole mounted outside the window.

The next task is fitting a 28 MHz dipole at or outside the window. Space is limited, so I am considering different layouts and ways to bend the elements. The final design has not been chosen yet.

DIGITAL MODESIC-705, Mac and FT8USB, radio control and digital audio.

I am connecting my Icom IC-705 to a Mac for WSJT-X. The focus is radio control, USB audio and testing reception and transmission.

Fldigi is a separate topic: I am getting familiar with the program and its settings. These are working notes, not a finished setup guide.

FEEDLINELess loss in the cableA new feedline project: HANSEN 1/2″ with RG142 tails.

I have ordered a replacement for the thin feedline: 9 metres of 50-ohm HANSEN LCF 1/2″ with two fitted N-female connectors.

The plan uses RG142 tails at both ends: 20 cm by the radio and 2.5 m through the window on the antenna side, with ferrite and a cable loop. The allowance for the turns still needs checking during assembly.

Measurements and a comparison with the old feedline come after assembly. This is the planned configuration, not a set of measured results.

ISS / SSTVAn SSTV postcard from the ISSAudio from a handheld radio speaker, decoded with an app.

During an ISS radio pass, I received an SSTV transmission with a Yaesu FT-70D handheld radio.

I captured the SSTV signal from the speaker and decoded it into an image using an app. The result was an ISS postcard for World Space Week 2025.
