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.

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.

Colin had just reduced his Landrover collection from 3 to 2 (real, not Dinky toys). Briain had been busy installing a new toilet and was celebrating with a Rioja. Not celebrating plans to build a tall extension next door. Peter DTH would have the audio recordings up soon including the last net with George's first appearance. Alan had been busy on the website, and looking forward to the next LRS meeting about Bletchley Park and a WWII Special Communications Unit near Balerno. Peter PXV had been sorting out his shack and doing a loft conversion. George was delighted to be on again via his 10,600km fiber-optic mic cable into BJF's remote Tx at Riselaw, at 04:00h local in the Phiippines! Brian (Peebles) would write up his set-up for the website. He was leaving on Friday to stay with Bruce in Mallorca and looking forward to the Spanish gin. Bill has had lots to do. He has 1980 RadComs for sale. Pete BYF was busy with preps for the Junk Sale on Apr 20th but will not be there himself. The 23cm contest last night was "dire" with only 8 QSOs. Still working on selling GM8GEC-SK items, as is Colin. Mike (mobile) just called in to say Hi to George.
