X Sweeper

Nearfield Receiver

The X Sweeper is a nearfield receiver with a graphical display that displays the nearfield RF (analog only) in a spectrum format, allowing the user to rapidly observe all signals that are present, not just one single frequency at a time. Once a signal is received, the X Sweeper demodulates the FM audio through its built in speaker.

With a frequency range of 30MHz - 3GHz, the X Sweeper can sweep and lock onto a broad range of frequencies in a matter of seconds. The 25 button keypad allows easy access to all functions, provides a direct numerical entry for the center frequency of the sweep range to be easily selected, and easily tunes to a specific frequency in VFO mode.


The X Sweeper has 5 different modes: SWEEP, SCAN, VFO, MEMORY and LOG MEMORY

SWEEP MODE: The center frequency and sweep span may be changed by direct entry from the keypad. The 10 sweep spans are, 3GHz, 1GHz, 300MHz, 100MHz, 30MHz, 10MHz, 3MHz, 1MHz, 300kHz and 100kHz.

MEMORY MODE: The X Sweeper has 10 different memory banks with the ability to hold up to 100 different frequencies in each bank. This gives the X Sweeper 1000 unique memories and the ability to store up to 65,000 hits per frequency. Each time a signal is received it is automatically stored with a time and date stamp as well as a relative signal strength reading.

SCAN MODE: The X Sweeper will scan all frequencies in a specific bank that were previously saved while in SWEEP or VFO mode. This is a convenient way to determine if frequencies captured from an earlier session are still active.

VFO MODE: The X Sweeper may be tuned to specific frequency in VFO mode. Frequencies may be programmed and saved to a specific memory bank for inclusion in SCAN mode. Frequencies may also be saved to MEMORY mode and locked out.


LOG MEMORY MODE: Log Memory Mode is a separate bank holding over 1900 frequencies with a unique time/date, signal strength, and latitude/longitude (with GPS option) for each frequency. This mode runs in parallel with SWEEP, SCAN and VFO modes and differs from the regular MEMORY in that it logs every frequency, even repeat occurences, to a separate memory allowing you to keep the first 1919 frequencies or keep the last 1919 frequencies captured.
