Great Statistical Analysis Program!

I've had to use cygwin64 and grep to attached data and then figure out how to parse it down more so Excel could load just a portion and create graphs.

So far, I've been using your program to compare various other modes to WSPR over the same paths. Rather eye opening when you do.

My only issue with using the WSPR data, is that while I know the power gain and radiation pattern of my WSPR reference antenna (TX and RX), I don't know what it is at the other end of the ether.

So, question, Jim. Besides the bandwidth reference for all modes as being 2500 Hz, what do we do for antenna differences, which will affect SNR. Or does it matter in regards to your matter of number crunching? Just wondering.

It's really too bad (IMHO) that WSPR doesn't allow for an APRS type power, height, gain and directivity (PGHR) encoded packet. UIVIEW32 uses PGHR (when available) to draw circle plots around APRS stations on maps to see where they overlap (Venn diagrams, if you will).

Anyway, Jim, you've done a great job of programming something that can "chew" on enormous amounts of data and produced meaningful information, which is the very definition of "data processing"!
