" RFI Eraser " : SDR# > IFavg > HL3D > Rinearn Software : Update

" RFI Eraser " noise reduction processing 

has been added to the HL3D Java code.

It seems stable &  effective, but I have a few more ideas for improvement.

Suggestion : 

Process the data first with Filter Width = 0 to get an uncorrected baseline of your data

IF there are RFI spikes in the spectrum, try Filtering 

Start with small filter width values, save the *.CSV file set & compare via Rinearn .

Over-correcting degrades the H data.

Uncorrected Data with RFI spikes

Small Filter Width correction results

Larger Filter Width correction results

AND, of Equal Importance : 

" RFI Eraser "    only adds a bit of smoothing to an RFI Free Data Set
