[FoxHunt] Test

[Jim Korenz]

 Averaging does help to some extent, but putting the bearings in bins, and displayingthe bin with the most hits, does a lot better. It doesn't take much memory, just 16 or32 bins for the direction. Experience shows that mobile Doppler bearings are aboutplus/minus 5 deg, so you don't gain anything over 36 bearings.   JimK N8PXW

 Hi,

That's what the switched capacitor filter does, integrates. A fast 
attack slow decay AGC will get the strong signal peaks when driving, are 
most likely to be the right direction, excluding buildings.

I've always wondered if in those time when a Doppler seems random in its readings if there was a pattern hidden underneath the multipath. It will be interesting if the SDR DF can do that. It doesn't solve and age old problem of if you can't hear it you can't hunt it.
