			Since we have QtRadio, we have a lot of Radios over the world, which cover the frequency spectrum nearly from dc to uhf. So it is often the case you come along some interesting, odd, seldom transmissions, which you ever wanted to record and maybe analyse later.

			The supplied script will, when started:
			*take you actual system time,
			*ask QtRadio for the actual tuned frequency,
			*will create a wav file stamped by the previos asked data (time+qrg.wav).
			*will, when you stopped recording, create a spectrum image from the recorded wav file.

			So, first we need some little helpful programms. Check if you already have or install:

	<pre>		<pre>
	sudo apt-get install sox		sudo apt-get install sox
Line 8:		Line 18:
	sudo apt-get install hamlib-utils		sudo apt-get install hamlib-utils
	</pre>		</pre>

			Here is the recording script. Copy it into you favorite editor.

	<pre>		<pre>
	##!/bin/bash		##!/bin/bash
Line 20:		Line 33:
	nano /usr/local/bin/qtradio_rec		nano /usr/local/bin/qtradio_rec
	</pre>		</pre>
			make the script executable:
			<pre>
			sudo chmod +x /usr/local/bin/qtradio_rec
			</pre>
			Create you favorite recording location, for example:
	<pre>		<pre>
	mkdir QtRadio_Recordings		mkdir QtRadio_Recordings
	</pre>		</pre>
			change to that directory:
	<pre>		<pre>
	cd QtRadio_Recordings		cd QtRadio_Recordings
	</pre>		</pre>
	Fire up QtRadio before starting the recording-script.		Fire up QtRadio before starting the recording-script and start the recording script from your recording directory:
