Information for 2022 D/F Hunt - NOTE LOCATION OF START POINT

The LRS D/F Hunt will take place on Wednesday 25th May 2022. Start 7.30pm sharp.

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 always room for those not equipped with receivers to join up with members who are so-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 1.875 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 the participants' mobile numbers so that in the event of them not 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 1.875 MHz can be provided if requested well in advance - contact Peter GM4DTH to arrange.

Colin commented about the Blackpool trip and forthcoming LRS portable activities. Peter had been carrying out maintenance on 2m aerial. The brass radiating element had improved the return loss by 5dB when compared with the original stainless steel one. Brian was preparing to meet roofers to carry out work in Edinburgh. He was also preparing to visit his grandchild in the USA for the first time and was going to the Dayton Hamfest. George had been operating 6m to the middle east once the JA stations disappeared. Alan MM0VPM had joined our net in the past and thought to call in again this evening. Pete had returned from a Swiss skiing and walking holiday. Brought home a supply of wine and a ‘Glen Turner’ whisky which had a sherry wood finish. Mike was returning from Murrayfield and he had been helping Melvyn painting his boat during the day. Briain called in late and has been fighting with modern technology.

power was varying, resulting in his signal strength varying between 57 and 10dB over 9. He plans to investigate the relays in his power amplifier. Briain GM8PKL reported the details of a high tech intercom based on computer networking technology for his mother to use as she is now back home. Brian GM8BJF had networking issues after reinstating his remote transceiver following his spell out of the country. Brian GM4DIJ was back after staying in Dumfriesshire. He had been active /P on various bands. George GM4COK / DU1GM had to be assisted by GM8BJF to work around Brian's networking issues. He has recently acquired a Chinese mini-whip active aerial. He was impressed with the aerial but was totally unimpressed with the thin rubbishy coaxial cable supplied with it. Mike GM8KCS/M, returning from Murrayfield, called in near the end. Peter GM4DTH had spent the day near Bathgate investigating a fault in a ground source heat pump.

"Developments and content of the WW2 secret British black radio broadcasts against the Germans. We hear fascinating tales both from SCU1 transmitter engineer Phil Luck and Ingram Murray, son of one of the most important Foreign Office officials that shaped operations. Developments and visits to the remarkable remains at Potsgrove and Milton Bryan studios. New secret papers unearthed from the propaganda manager’s trunk".
