I have a relay on a mountain top, some 300m above sea level and have been getting some good results. The furthest range I have obtained is 50km. I leave a radio connected to a phone at home, with a connection to the mountain top relay, I take another radio with me in the car and periodically send messages at landmarks on my journey. Messages are sent, but they are not confirmed as being received on my mobile radio app, but yet when I return home the messages have been received on the home radio app.
How can this happen? Can I fix it by increasing a timeout setting? Also if my mobile radio transmission is being received by the relay, surely then I should be receiving the relay’s position, signal strength, etc?
