In the continuing saga of being good APRS citizens, there is a new feature on http://APRS.fi
- "radio horizon circles."
The new feature is described in a new blog post
The horizon circles show the estimated reception range at 5 degrees and to the horizon. They are specifically targeted at airplanes "for estimating the distance at which the station can be heard [and] gives pilots an idea of the large amount of digipeaters and igates in range"
I take this as another example that those of us flying with APRS trackers need to educate our brethren on configuration. I think the VAF readers are way ahead of the curve on being responsible and this forum has been especially helpful for me
I believe WIDE2-1 is our best option presently. At the same time, I will reach out to the amateur radio community to help them understand the significant dynamic operating range aircraft operate and the challenges with further "damping down" airborne configurations. If I find a better configuration, I'll post updates.
