Doing some experiments with #meshcore on #433MHz
A drive test shows very good results.
Heltec v3 as companion and lily as repeater.
At 2km distance still 10dB report.

Mihin olettamukseen perustuu se, että reitti olisi aurattu lumesta? ☝🏼😸☃️ #70cm
Kartenausschnitt eines kleinen Stücks Südwestdeutschlands, auf Freiburg zentriert. Man sieht u.a. Teile Frankreichs, Luxemburg und die Schweiz. Die Grafik zeigt 8 Verbindungen in verschiedene Himmelsrichtungen nach Deutschland, Frankreich und in die Schweiz
Trotz Backup-Antenne und wetterbedingt unperfektem Standort (nicht so hoch wie ursprünglich geplant) doch noch 8 70cm-QSOs geschafft, davon einmal knapp 140km in Richtung Besançon und 135km nach Sarreguemines.
Mit HB9CV in der 70-cm-Variante und 6W.

The #Baofeng UV-5R mini is a nice looking handheld #radio #transceiver but the stock #antenna is worthless on #2m #145MHz
This Retevis RHD-701 works much better.

Anyone doing the #RSGB high altitude ballon comp on Saturday. I'm thinking of going up one of the Lomond hills to see if I can hit the repeater. I'll be using a different antenna on the tracker, hopefully I'll manage to get spotted. #heltec #tracker #70cm #LoRa
#resist big tech wants to use ham radio freqs in #70cm band. 70cm band is popular for handheld local #ham #radio use. Why this is important ? Ham radio is the backbone of point to point emergency no charge comms. Screw these big companies youtu.be/QtuzJsbZTHU?...
My old #frequency #counter couldn't handle #23cm so that's a good reason to build a new one (up to 2.4 GHz).
After adding a #preamp, the counter easily picks up #70cm from 5m.

added to my website, but not published yet, hopefully get some more images the next few days
A good evening for my modest setup taking part in the RSGB 432UKAC contest this evening with 23 ITL. #FT817ND #QRP #5W #70cm
If you wanna do #HamRadio / #AmateurRadio at the same while doing #WarDrive things you need to filter out the low 2m/70cm (140/440mhz) freq from blowing up the WarDrive rig. #WiFi #Wigle #Yaesu #2m #70cm
The Yaesu #FTM500 is 50W of TX power.
It's still a risk.
But we shall see how it all does.
