VKS-737

MOBILE RADIOS

VKS-737 subscribers are authorised (under Section 114  of the Radiocommunications Act) as "mobile" stations by the Australian Communications and Media Authority (ACMA).

To communicate within the Network, subscribers need to have an ACMA "type approved" High Frequency SSB long distance transceiver.

Not to be confused with CB radios that are widely used, the long distance HF radio is larger, more powerful and can only be used by licenced persons.

HF RADIO UPDATES

In recent years, there have been significant advances in the design of HF radios; these features include hundreds of channels, enhanced receiver noise reduction, digital voice transmission and reception, automatic tuning antennas, direct telephone dialling, faxing, email, beacon, selcall and GPS data transmission.

ABOUT HF FREQUENCIES

VKS-737 subscribers are not permitted to use any other transmit frequencies fitted to their radios unless authorised to do so.

Users wishing to use RFDS frequencies must obtain an Outpost Radio Licence from the ACMA and use the ACMA supplied callsign, when on those frequencies.

Users wishing to use frequencies belonging to other organisations or companies must hold an authorisaton (under Section 114 of  the Radiocommunications Act) from that  organisation or company.

Sourcing of radio hardware can be achieved via the second hand market, or by purchasing new units. There are often radios PRIVATELY OFFERED for sale on our Market Page.

Technical information on HF Radio can be accessed via links on the AIRWAVES and LINKS pages.

If you need assistance in selecting radio hardware, staff at VKS-737 Radio Network Head Office may be able to offer assistance, email or telephone Head Office on (08) 7325 2600.

USING GPS WITH YOUR HF RADIO

Many modern HF radios have Global Positioning System (GPS) software installed by the maker.

This allows your location coordinates to be transmitted by your HF to a remote suitably equipped station.

While this may be desirable for users in certain circumstances, the VKS-737 Radio Network cannot offer to accept and process this data.

Important advice for all VKS-737 Subscribers.

It should be noted that under ACMA Licensing conditions DATA can NOT be transmitted on the VKS-737 VOICE ONLY Frequencies.
