 <p>
 Multiple channels can be useful, to keep the control channel, while establishing one or even multiple voice channels.
-One nice things about SDR is that a spectrum is transmitted and not just one modulated carrier.
-Because the carrier is actually generated in software, we can generate multiple carriers that fit in our bandwidth.
+One nice feature of SDR is that a spectrum is transmitted and not just one modulated carrier.
+Because the carrier is actually generated in software, we can generate multiple carriers that fit in our spectrum.
 I suggest to have at least one channel space between channels you want to generate.
 I suggest to use channel 1 and 3 or even channel 1 and 4 for NMT system.
-The software will notice you, if the channels wont fit into the bandwidth.
+The software will notice you, if the channels wont fit into the spectrum.
 In this case increase the sample rate (-s) to generate a wider spectrum. (--sdr-samplerate must not need to be changed)
