 A simple scanner written in C that uses gqrx remote protocol to perform a fast scan of the band. It can be used in conjunction with the gqrx bookmarks to look for already stored frequencies or, in a free sweep scan mode, to explore the band within a specified frequency range. 
 
-The sweep scan uses an adaptive algorithm to remember active frequencies during the sweep that prioritizes active stations without stopping the search for new ones.

 Gqrx Squelch level is used as the threshold, when the signal is strong enough it stops the scanner that in turn adjusts the frequency to the nearest carrier seen.

 In sweep mode use a limited bandwidth of about 2 MHz in order to avoid VFO and noise floor levels chainging during the sweep.
