I can’t seem to leave this ADS-B thingy alone. I keep coming back to it again and again. Lack of better things to do, I guess?
I had a ‘truckload’ of problems lately, some described in previous posts. Replaced every piece of hardware on both my stations at least once. Still no permanent fix, until late last week, knock on wood.
If this latest ‘solution’ holds, the problem had to do with weak wi-fi signal, either on the router side or on the RPi side. I would be most interested to hear from those that my have run into this situation as well.
I installed a brand new router in range extender mode half way between the ‘WAN’ router and the RPis.
In addition to replacing pieces of the stations when troubleshooting the connectivity problem, I also moved the antennas inside the garage a lot. I remembered where the antenna used to be when I received the largest number of planes since I setup my first station. Would you believe it that that location ‘worked’ again. There is a so called ‘sweet spot’ in the garage for best antenna siting. Then there was the N to SMA adapter issue mentioned in the past as well.
I had already mentioned many times before that indoor antenna siting can be very sensitive to literally inches of change, in all directions. I failed to record the different results as I moved the antenna around over the years. I have also concluded that when the performance went down a year or two ago, it was because of the N to SMA adapter. This made me change the antenna location many times, looking for a better place, and put me in this ‘wild goose chase’ kind of situation.
This is all to say that I think I may have maximized my stations for the highest number of planes possible in this location, with this setup. This would certainly change if the antenna moved outdoor and higher, for example, but that is not happening.
With plane seen maximized, I’m now looking at message numbers. I want to understand more about messages, and what kind of correlation it may have with the number of planes seen.
My first question then is: My two stations are only 20 inches apart now. They both see pretty much the same number of planes. However, the difference in the number of messages received, with pretty much the same number of planes, sometimes higher on the station receiving less messages, can differ by up to 80%, like at this very moment while writing this post. What could be the reason for this?
Sorry for the long winded post.
