Last week’s lecture on RADHAZ i.e. Radiation Hazards by Allan VK2EFM was most informative. It started with the basics of electromagnetic radiation e.g. the E-field (electric) and the H-field (magnetic) at 90 degrees to it. Basic calculations were shown, such as volts/metre from the E-field and amps/metre from the H-field. Did you know that it only takes 6 minutes of over-exposure to RF to heat body tissue and cause injury? Various other risks were mentioned, such as ignition of fuel, gas and explosives, and the effects on cruise control in vehicles. This was followed by a practical demonstration, with Club President Myles VK2ASS as the guinea pig.
The next business meeting of the Club will be next Saturday 3rd November, and all are invited.
And don’t forget the forthcoming Wyong Field Day next year, on Sunday 24th February; this event is sponsored by the Central Coast Amateur Radio Club.
All meetings of the Central Coast Amateur Radio Club are held at the Clubrooms in Dandaloo St, Kariong, just past the fire station at 1pm, preceded by the famous sausage sizzle run by master chef Steve VK2SKC, starting at noon. The Club rooms are accessible by bus, with a stop just opposite Dandaloo St, serviced by the route 34 bus from Gosford railway station every hour. The Club rooms are usually open from 10.30 every Saturday, for general chit-chat and access to the Club workshop and library.
The Club relays VK2WI News broadcasts every Sunday morning and evening. Callbacks are taken after the morning news only, on the Somersby 6m and 2m repeaters VK2RAG on 53.725 and 146.725 MHz respectively; please note that both repeaters require the standard sub-audible tone of 91.5 Hz.
The Club also runs a mixed-mode repeater VK2RAG on 439.950 MHz, which is connected to the P25 network; the 91.5 Hz tone is required for analogue access, and is highly recommended for receiving.
There is a net held every Thursday on the 2m repeater VK2RAG on 146.725, starting at 8pm; all members are encouraged to join (especially if Club news for the ARNSW broadcast is involved). Club news is happily accepted at “firstname.lastname@example.org”, preferably by 12 noon on Friday.
The Club also has a Facebook page: just look for “centralcoastarc”. There is also a Twitter account on @ccarclub.
