from AR Magazine 1986 July page 52 - A group of 14 members and three visitors attended the last meeting of the Branch, where all routine matters were attended to. During General Business, the meeting was told that a new Broadcast List would be prepared shortly by the Southern Co-ordinator. VK7s OW; KH; SF; EG and ZBT were thanked by Rob VK7KAB, for their assistance with the Rotary Display Auction which was held during May. Rob also suggested that planning work should begin now lor TARK 87, and members should begin collecting surplus equipment for the TARK auction. Planning for Camp Quality is proceeding very well. On the first Sunday in May, the VK7WI Weekly Broadcast began at 0900 EST and resulted in Andrew VK7ZHA being awarded the Gong Award for the month � he forgot the change of time and slept inl The club now has its own QSL card for station VK7NW, which coincides very well with the setting-up of the station in another part of the Penguin High School. Recent Activity Nights have been taken up with the move as the new room is on the opposite side of the building. As the new room is much larger for the permanent set-up of VK7NW, regular operation from the station should be much better. Greg VK7ZBT, has been given the job of procuring a Great Circle Map and Bill VK7WL, is to get a large map of Australia for the station wall. There is still much work to be done with the aerials and Greg has volunteered to make a 70 cm antenna. There has been very little RTTY operation of late, but with the new location it is anticipated that regular broadcasts will resume. (Just now soon this happens of course will depend on how many volunteers volunteer when needed). One of the Branch members, Owen VK70L and his wife Nancy, are doing an extensive trip of the mainland, visiting their children in South Australia and Darwin. They also intend to visit many amateurs along the way. Owen and Nancy are expected home next month. Meetings of the Branch are held at the Penguin High School, on the second Tuesday of each month, commencing at 7.30pm. Visitors are most welcome and are directed to the venue via the two metre repeater � Repeater 3. On 20th April, the North West ATV Group commissioned its second Amateur Television Repeater. It is operational under the call sign of VK7RAE. The repeater is located on Kelseys Tier, near Devonport on the property of Ron VK7RN. Ron has kindly made his properly available as a site for the repeater and thanks are extended to him. The prime role of this repeater is to allow amateurs in the Devonport area to transmit and receive noise-free pictures in Devonport and the surrounding area. Uplink vision carrier frequency is 444.250 MHz and downlink 579.250 MHz (Horizontal Polarisation). Persons interested in viewing the output channel are reminded that the downlink frequency falls In Band 4 allocation of the UHF Television Spectrum (put simply, this appears at Channel 34V4 on a standard UHF television tuner). However, the proverbial piece of wet string will prove insufficient for noise-free reception o f the device as its power output is relatively low. A good quality high gain antenna cut for UHF will guarantee good pictures. The radiation pattern is omnl-directional with a full 360 degrees in the horizontal plane. Known amateurs to be transmitting good quality pictures through the repeater are Jack VK7WJ and Andrew VK7ZAR It may be timely to point out to listeners that we often hear and read that the majority of amateurs are Black Box and appliance operators these days, and where are the true amateurs ???This repeater and the other ATV repeater, (VK7RTV, which is Installed on Mount Duncan), with the exception of the receiver IF systems, are completely home-brew. This includes the receive converters, control systems, transmitters and all antennas. To date, much experimental work has been carried out by the ATVers with antenna and propagation on the UHF bands. Thanks to Tony VK7AX for supply of the ATV notes. Contributed by Max Hardstatt VK7KY AR
