<p>Ten memory and band keys to switch either between ten stored memories or to switch between the ten pre-set amateur HF bands when in VFO mode. Up / Down step keys jumps in 1Mhz step.</p>
<h3 id="antenna-tuner">Antenna Tuner</h3>
<p>I tried and failed to find a simple explanation of an antenna tuner it’s a complicated topic, I can at least have a go at explaining how to use a simple manual antenna tuner, hope this makes some sense.</p>
<p>A typical manual Antenna Tuner has two rotatable knobs both interact with each other. The Tuner is used to match a badly tuned antenna to your transmitter. The Tuner is placed in-between the transmitter and antenna. To use it you typically hold down the transmit key while looking at the VSWR meter and rotating one knob at a time in turn repeating this operation until the minimum VSWR is achieved.</p>
