Page 5: Antenna Recommendations And Installation
ANTENNA RECOMMENDATIONS AND INSTALLATION Mobile antennas Consider using a helical whip antenna. Helical antennas can be made with quite manageable length, much shorter than a resonant whip (not helically wound) that would need to be about 2.5m long. Any whip antenna requires a ground plane to operate efficiently (eg car roof, bonnet or lid of the boot. -
Page 6: Adjustment Of Swr
5. ADJUSTMENT OF SWR (Standing Wave Ratio) The antenna you intend to use with this transceiver must be “matched” or tuned to the operating frequency to ensure maximum energy from the transmitter is transferred to the antenna. This means minimizing any energy that is reflected back down the coaxial cable from the antenna to the transmitter, as this can damage the output devices. -
Page 7: 10 Metre Band Propagation
10 METRE BAND PROPAGATION The 10 metre band can yield very surprising results in terms of DX contacts. Whilst scanning the band can yield few results, once a call is made the response can be amazing. Seems many DX stations are just waiting to be called ! Depending on the level reflection in the ionosphere, signals can propagate further than normal, during “greyline”, the transition from sunlight to darkness. -

<C � CHANNEL Rotate clockwise to switch on the radio and set the desired volume level. Under normal 1.OFF/ONNOLUME operating state, the VOLUME control is used to adjust the output volume obtained either by (Inner Dual Concentric) the transceiver speaker, or the external speaker, or the external PA speaker, if used. This control is used to cut off or eliminate receiver background noise in the absence of an incoming signal. - Page 10 (1) RB Press the "RB" key to enable the "ROGER BEEP" function with the "RB" icon appearing on the LCD. Press the key repeatedly to switch on/off the function. When the RB function is enabled, the radio will automatically transmit the audio signal at the end of your 16.ROGER BEEP OR BEEP FUNCTION transmission.

Page 15: Licensing Requirements
LICENSING REQUIREMENTS You need an Australian amateur radio qualification to operate this equipment. In Australia, the ACMA has powers to make technical specifications for radiocommunications equipment under the Radiocommunications Act 1992. However, the primary tenets of the Amateur Radio service are technical investigation, experimentation and self-training; hence, Australian Standards for radiocommunications equipment are not applicable to amateur stations. -
Page 16: Beacon Propagation, Beacons
BEACON PROPAGATION It’s a great idea to check 10 metre amateur radio beacon activity to see how good the band conditions are. Check VK6RBP on 28200 Khz and ZL2MHF on 28229 Khz for an indication of propagation. There is an internation service called the IBP (International Beacon Project) where stations around the world transmit at given times, sequentially on the same frequency (28200 Khz). -

As the 10 meter band can open suddenly some repeaters require transmission of a CTCSS tone for access. -
Page 19: Programming The Hs4 Transceiver
Programming your HS4 10 metre transceiver The HS4 transceiver allows user customization of channel data for the 10 metre amateur band. Frequencies for allocated channel numbers (Tx and Rx), CTCSS/DTS encode and decode frequencies, as well as Echo, Busy, Hi-Cut NB/ANL, RB and scan can all be customized to the user preference. -
