Today out at the top Mont Sujet / Spitzberg (1382 meters above sea level / JN37ND) with the radio to have some very friendly QSO‘s. Today with the Jopix CB-514 handheld radio and the new diy L-Match. Cows forced me to search for a new place, which I found some meters below the top of the mountain.

Today out at the former Coast Station Berne Radio HEB in Bern / Riedern (620 meters above sea level) with the radio to have some local QSO‘s. Today with the Jopix CB-514 handheld radio and the new diy L-Match.
And this is not a joke, Switzerland had from 1941 until 2016 a costal radio station.

@phaysis Same problem here (Heltec Wireless Stick Lite v3 with 2.6.4). It’s a little bit annoying to reset always the device (It’s on the roof) 🤬

Quick & Dirty Sunday DIY Project. L-Match for 27MHz.
Toroid : T80-6 with 23 turns (~2.62mH)
Capacitor : 2pF - 30pF
Network Type : L-Match

Wait for better weather to test. But with 4.4k resistor I can match a VSWR 1:1.1

📍 🇨🇭 map.geo.admin.ch – Best for Switzerland, highly detailed terrain & infrastructure

🌍 heywhatsthat.com/profiler.html – Great desktop tool with advanced profile parameters. Less mobile-friendly, but powerful

📱 rflineofsight.scadacore.com – Mobile-friendly line-of-sight tool by ScadaCore. Quick & clean!

🌐 arcgis.com/apps/Profile/index. – Ad-free, reliable elevation profile tool with solid global coverage

Die meisten Funkverbindungen prüfe ich auf map.geo.admin.ch/
Besonders interessant ist die Luftlinie sowie das Profil. Auch für die Standortsuche ist diese Seite top.

I use Lilygo‘s T-Deck for Meshtastic but without the Meshtastic UI, still use it with Cellphone App. Btw. The pice between the antenna plug and antenna is a bandpass filter.
