<div> </div>
I moved the receiver and antenna outside this evening to see how the range improves. It is only right above the peak of the roof and the antenna is about 12-18" from the conduit holding the CX333, but it is hearing pretty well so far. If anybody is interested in seeing the live plots reply privately and I'll share the URL. I just don't want it getting cached by the google. https://i.sli.mg/Mxs3k7.png On 5/23/2016 12:45 PM, David McKenzie wrote: > After a few days logging ADS-B and mode-s transponders from aircraft > overhead here's how it hears.
