Flying back from Atlanta to Jackson, my Echo Flight finally received its

Bendix/King RDR 2000 on-board radar. It shows nothing. Nothing on the
stormscope.

Why the huge contrast between the on-board and the Nexrad return? Perhaps
the Nexrad was picking up water far above me, while the on-board was looking
ahead (I was at 5,000.)

My guess would be the EchoFlight system had an issue. A friend of mine
had that system and kept trying to get it work for 2+ years. He had a lot
of issues with accuracy. He has recently abandoned the system and has gone
to WxWorx with XM radio. That system is working much better for him.
