Brian:
Thanks for working the "can't see adsb towers" issue with me. It appears I may have wasted your time. Here's why.
I typically fly out of Corona (KAJO) here in SoCal in the area between Fullerton and Palm Springs.
I looked for the towers in this area, but couldn't see them. So I sent a couple logs for you to peruse. In one of your responses you had a graphic of a map showing a tower about 20 miles north of El Monte Airport.
The next ime I flew I looked for that tower and could see it along with one more tower west of it just above LAX near the coast.
In the area that I typically fly my ADSB says I'm talking to 4-5 towers while at 3500 MSL. I am still curious why only two towers are depicted when I have 4-5. Thay can't be too far away if I receive them at 3500 MSL.
In summation, I guess my phone and tablet are showing towers so all must be OK technically with my equipment. Just wonder why only two of the 5. Next flight I am going to zoom way out and see if I can spot the rest of the towers.
Thanks again for the assistance. The IFLY staff is the most responsive support group I have ever delt with.
By the way. Does anyone know if there is a source where we can determine the location of towers while at our home computers. I will check Google Earth.
