UPCOMING MEETINGS
-
Wed 27 May – 19:30h – Top Band D/F Hunt – Peter Dick GM4DTH.
The start point avoids the high noise level experienced in earlier years near the Braid Hills Hotel. Members (or visitors) wishing to take part are advised to be on Braid Hills Road at the sign for Braids Golf Course (junction with Braid Hills Ave / Braid Hills Approach / Braid Mount (NT-246698) no later than 7.20pm, although this is not essential – some entrants choose to start from elsewhere. There is usually room for those not equipped with receivers to join up with members who are equipped. The “Fox” will be located somewhere within the City boundary and participants should be equipped with a map and the necessary equipment to draw out bearings. The Fox will transmit using the callsign GM3HAM/P for 5 minutes-on / 5 minutes-off periods starting promptly at 7.30 pm. The frequency will be 1.873 MHz with an amplitude modulated tone being broadcast plus voice identification at the start and end of each period of transmitting. Operation will cease at about 9.30pm and an informal gathering will occur at a pub not too far from the Fox’s location, which will be announced at that time.
Participants are advised to be equipped with a mobile phone. A coordinator will be available at the start to provide the mobile number of the fox station (Peter GM4DTH) and to register who is participating. If a hunter is encountering difficulty in locating the Fox, they can request clues regarding the location of the Fox station (or the pub)! Each clue provided will incur a penalty of 20 minutes. Test signals similar to those of the Fox on 1.873 MHz can be provided if requested – contact Peter GM4DTH to arrange.Wed 10 June – 19:30h – LRS Pub Night at Wee Bennet’s Bar, Morningside Stn.
