IFR-1200 sweep of the tuned 10.7 MHz IF 300 kHz BW resolution filter.

This is the same design as in the W7ZOI/K7TAU spectrum analyzer project from the August 1998 issue of QST, but with a few capacitor changes to move it up to 10.7 MHz.

First view is 1 MHz per horizontal division and 10 dB per vertical division then the span changes to 100 kHz per horizontal division.

Ignore those spurs to the side of the sweep.
