Edited the 3 WiFi values for Australia "AU" in the config file, but WiFi does not work.

I can edit via sudo raspi-config and it runs ok.

Hi,
I just wanted to use the image from here: http://download.glidernet.org/seb-ogn-rpi-image
I am on a Mac. I am using the balenaEtcher to write the flash card.
The flashing fails and it claims the image is broken. The same happens if I use the build-in Mac image-recovery tool. Any idea?

Thanks

Thanks to /proc/device-tree/model

Hello Snip, regarding
tag v0.3 i have installed on a Raspi 3B (without plus).
It is connected via ethernet to a DSL-router, WiFi disabled.
The system does stops its alive message every night at about 4:00 am.
See EDPJ2 and
ognrange.
May this be caused by the cron job to reboot every morning.
Infos: The LED at Raspi blinks in this case. Its real position is nearby airport EDPJ in the city eastern.
Any idea?

By default the OGN gain is always 60, sometimes that is too much and gives intermodulation, so a new parameter like OGNGain='48' will be helpful

Still need to find how to report it.

If not provided in configuration.

Can be based on:

• public IP -> Not very reliable
• Wifi MAC adresses -> Only if Pi3 or other Pi with wifi dongle.
  (https://developers.google.com/maps/documentation/geolocation/intro)
• public IP + OGN receiver selecting only strong signals
• Listen to GSM signal thanks to RTLSDR

One small thing that it will be handy, it will be to add "hostname" to the configuration parameters (OGN-receiver.conf) the possibility to change the hostname, instead of the default of the ogn-receiver

This can be useful to patch network config.
Existing runAtBoot parameter is only used after internet connection is established.

This will allow the nightly reboot to occurs during night on all location.

Or this can be detected approximately from longitude value.

Sometimes OGN-receiver-config-manager is not working:

Maybe due to time not in sync which results in https issue?
