    The $20 RTL2832 – E4000 based Newsky TV301U USB dongle receiver can be used
    as a Poor Man’s Spectrum Analyzer. The SDR# program is zoomed to display
    about 20 kHz of RF spectrum centered on 145.25 MHz. The display shows the
    frequency deviation of a short transmission with a Yaesu FT-60R handheld
    without CTCCS tone, followed by a transmission with the tone turned on. A
    momentary increase in transmitter frequency is observed at the beginning of
    each transmission.

    Below the panadapter window, the waterfall shows a momentary increase in
    the frequency at the beginning of each transmission.
