sounder can also be seen. The 3 KHz wide signals are the actual SSB stations. This image is at a RBW of 74Hz.

This spectrogram shows the 14.0 to 14.1 MHz CW portion of the Amateur 20 meter band on a Sunday morning.

The update speed is so fast that the CW can actually be read on the screen.

This spectrogram shows the 14.0 to 14.35 MHz Amateur 20 meter band. This image is at a RBW of 74Hz.

This spectrogram shows the 144 to 148 MHz Amateur 2 meter band. The FM repeaters can be as well as the

packets stations keying on and off. There is some cable TV egress showing up as evenly spaced vertical

lines.This image is at a RBW of 1KHz.

This spectrogram shows the 28.0 to 30.0 MHz Amateur 10 meter band. This image is at a RBW of 813Hz.

Avtec IF downconverter IFQ

Converts RF directly to baseband digital signals that are sent to your PC via a USB 2.0 port. User must write

their own software to control the downconverter, select the frequency, and demodulate the signal. To use this

device, you would also need to add a front end with an LNA + some type of mixer to generate the 100-195 MHz

IF. With some work, this digitizer board could form the basis of a nice SDR.
