Check it. The overview graph now has a highlighted section that indicates which portion of the 190 KHz is being viewed in the bottom two graphs, and you can drag the highlighted area around as one would expect. And I ditched the extra device control window and built it into

Since I started zero-padding out the fft, the entire 190KHz span can't be viewed at 100% zoom, so I added this very short planar graph at the top which shows the entire span, while the two larger graphs showed a zoomed-in portion of the whole. I need to

I successfully tore out the old ftdx usb driver from Static and implanted libftdi which works completely differently, of course. I spent all day Saturday racking my brain trying to figure out how to manipulate the quadrature data to make it suitable input for the Chebyshev IIR filter (without success)

Centered around 146.575MHz is this crazy signal. Sadly, my HT can't distinguish the signal beyond noise, while the big antenna is only connected to a program that can't demodulate (as of yet). So I'm left to wonder. It sure looks interesting though. I&

So I finally noticed these crazy little 9V DC input pins on the 144-148MHZ down converter. Apparently it needs to be "plugged in". So I deftly wired up a 9V battery to it.
