    1. Codan NGT Redcliffe and Districts Radio Club Guidelines

    2. NGT features 100W, AM, LSB, USB, ALE, CCIR selcall, GPS, SMS Rugged commercial grade construction HF speed data modem Extra cooling fan 2.4 kHz IF filter

    3. Handset Controls PTT Channel up/down Volume up/down Mute Easitalk (IF DSP NR) Call Mode (USB/LSB/AM) Find (magnifying glass)

    4. Desktop accessory F1 - Call F2 - Hangup F3 - Mode F4 - Mute PTT

    5. Club NGT setup Runs on the 12VDC system Antenna is a broadband terminated folded dipole, hence an antenna tuner is not required You are unlikely to work DX on this antenna!!!! The radio is turned on 24/7, scanning HFN and WICEN HF (region 3) HF Express and STANANG stack is installed on the adjacent PC

    6. Land Mobile versus Amateur It is illegal to use non-type approved equipment on land mobile frequencies HOWEVER, you can use a land mobile transceiver on Amateur allocations A type approved transceiver must not be programmable through the front panel, that is, it must be channelised, and only be programmed by a dealer Examples of land mobile network frequencies are RFDS, VKS737, VMS469, HF Oz, EMQ/SES and the 2 x 5Mhz Emcomm frequencies allocated to the WIA Many other users, e.g., military, aid agencies, police, ambulance, emergency services and long haul aircraft use HF land mobile on a daily basis

    7. Amateur frequencies The NGT has the amateur option, pressing the 4 button will run a macro to put the set into Free Tune TX Note, you will only be able to FreeTune TX within the Amateur allocations Use keypad to shift digits, and channel up/down to change the number AM, LSB and USB modes are available at 100W For F-calls, you can turn the power down to 10W

    8. Land Mobile allocations VKS737 Australian 4WD Network VMS469 Reids Radiodata Bush Telegraph HF Oz Travellers Network None of these networks maintain a voice listening watch, requiring a selcall to call an operator N.B. The club does not have authority to transmit on any of these networks, hence to be used ONLY in an emergency

    9. Other allocations CB 27MHz chook band Marine now requires DSC, not supported by this NGT RFDS Royal Flying Doctor Service Again, these allocations are not monitored for voice calls, a two-tone alarm is required (Emergency Button) is required to get some bodies attention N.B. The club does not have authority to transmit on any of these allocations, hence to be used ONLY in an emergency

    10. EMQ/SES Four networks utilising ALE/CALM for sounding every 4-5 hours. EMQ statewide SES South SES Central SES West N.B the channels on this network must only be used by members of the SES SCG, the callsign is VKQ609 followed by your identifier, e.g., my identifier is SC1

    11. Networks Networks are used by the NGT to manage different calling systems. That is for VKS737 and WICEN HF -> open selcall (4019), for HFLink, ALE (VK4RC), for EMQ -> CALM (401909), Networks configured are WICEN HF (3600, 5355, 5102, 7075, 10115, 14125, 18150, 21190, 24950, 28450) Global ALE HFN (3596, 7102, 10145.5, 14109, 18206, 21096, 24926, 28146) EMQ/SES Land Mobile (VKS737, VMS469, RFDS) 27 MHz CB

    12. Selcall versus ALE (CALM) Selective calling Radio to radio Beacon or test calls SMS GPS position dispatch and requesting Two versions in use, Codan (4 or 6 digit) and Open (4 digit only) ALE Automatic Link Establishment Codan have extended the MIL-STD-0188-0143 functionality and termed it CALM (Codan Automated Link Management) Same functionality as selcall, but no test/beacon call available Able to query radios for status, diagnostics, GPS which is not supported by MIL-STD-0188-0143 However, a CALM radio can participate in a MIL-STD-0188-0143 scheme (e.g. HFLink)

    13. ALE?, no it is not a beer Designed to take the technical know how of HF propagation out of operating HF Each transceiver in the network will periodically sound on each frequency, any transceiver scanning those frequencies will log the time, BER and SN into its memory So when an operator wishes to call another station, they enter the ID of the target and press call, the radio determines the optimum channel according to the time of day and attempts the call. It will keep trying on that channel twice, if no success it will begin to try other channels For this to work, the radios must be turned on, and setup to scan/sound 24/7.

    14. Global ALE HF Network ALE is not confined to land mobile users A global network has been setup using Amateur radios and soundcard interfaces Two pilot stations are available in VK, VK5ABN, anybody want to guess who else? HFLink provides email services and SMS services globally http://hflink.net

    15. STANAG 5066 modem A high performance HF modem has also been acquired These modems are used by QPS and EMQ for secure file transfer and secure text chatting Without requiring the Internet, we are able to exchange files with QPS and EMQ securely with strong encryption The applications are many and varied, e.g. weather maps, site photos, SES RFAs, message forms

    16. HF Express The PC adjacent to the NGT has the Stack control and HF Express software installed A unique address has been allocated to the stack, much like an IP address (0.0.0.5) To transfer files, simply drag and drop, to and from the remote PC
