The group provides a forum and focus within NSARC for those wishing to participate in HF radio activities. HF radio has a lot to offer - technical development, operating skills and emergency preparedness. For those with Basic Licences wanting to enjoy the full scope of opportunities offered in Ham Radio, and those who already have HF privileges but are looking for advice and mentoring in HF, this is the place to be.
We have projects planned and regular meetings scheduled with a view to involve interested members in theory and hands-on activities. These projects promise to be informative, practical and interesting.
All members of NSARC are invited to drop in or become involved.
Currently NSARC has 3 HF operating positions, consisting of an Icom IC-756 Pro III with an Icom IC-2KL 500W amplifier, a Flex -3000 SDR and a Icom IC-718 as a GOTA station. These are all fully capable HF transceivers.
We have three antenna systems, a 160m inverted-V and an N4PC loop, both with SGC automatic couplers at each antenna feed point so that they can be used on all HF bands, and a rotatable 3 element SteppIR auto-tuned Yagi. The inverted V can also be remotely reconfigured to a top load vertical for low band use. A patch panel allows any rig to access any antenna. Patchable band isolation filters allow simultaneous operation of stations. Even our VHF/UHF station, with it’s Icom IC-7000, having HF capability, can be patched through the panel to these antennas.
The Pro III, SDR and GOTA positions all have PC control for logging as well as providing for digital mode operation. The PC’s have sound cards, and the radios have sound card interfaces. All radio positions in the communications room are inter connected to our dedicated LAN. The positions are equipped with SWR/power meters, low pass filters, and dummy loads. Individual band pass filters are available for multi station operation. An IC-2KL 500W amplifier is dedicated to the SteppIR Yagi.
The station is open to all members who might want to operate HF. Remember you can only operate to your licensed qualifications unless there is a control operator present with a higher qualification. (If you hold the Basic qualification without Morse Code, and do not qualify for HF operating privileges, a control operator with a higher qualification must be present.)
During the 2011 – 2012 timeframe, a new operating position was built. The Icom IC-718 GOTA station returned to the air at this new position, having been sidelined for the installation of the SDR the year before. Although the 718 radio figures prominently at this location, this position has been equipped to operate as a multi–functional voice and digital text station. The PC at this station is configured for multiple duties as follows. Firstly, a Pactor III modem is connected to the 718 to provide HF texting capability. Secondly, our separate and existing VHF/UHF packet radio system with its 3 radios and TNCs terminates in this PC as well. Thirdly, a BCWARN terminal was installed that also terminates in this PC providing VOIP and text.

For operators who would like to experience or operate an HF station, a number of club members would be happy to have guest operators work out of their home stations. This opportunity offers a "one-on-one" mentoring environment to become familiar with HF station equipment and operating procedures. This can be rag chews, nets, contests, DX'ing, digital modes, or just HF discussions, and so on.
Please arrange visits individually with the members listed below.
