Eventual winner Melvyn GM4HYR making his first decision on which direction to boldly go to find the Fox station GM3HAM/P.
The LRS annual D/F Hunt was held on Wednesday 25th May 2016, organized by Peter Dick GM4DTH using the callsign GM3HAM/P transmitting on 1.875 MHz. There were only two receiving stations - Melvyn Bond GM4HYR and Mike Brunsdon GM8KCS (assisted by son Mike Brunsdon Jr MM3MDB and Alan Masson GM3PSP). The fox station was located close to the Union Canal near the Slateford  aqueduct and was first found by Melvyn GM4HYR in 1h 4m  followed by Mike GM8KCS and his team in 2h 1m. After the event the participants adjourned to the nearby Blue Goose hostelry for diet lemonades.

At the meeting of the LRS on 11 May 2016 LRS President Andy Sinclair MM0FMF talked on "Holiday HF - or how to have your cake and eat it". His informative presentation covered the practical aspects of preparing for and operating a successful DXpedition - researching and knowing the foreign regulations, obtaining a CEPT TR61/01 foreign licence when necessary, luggage regulations for checked-in and carry-on bags, especially regarding batteries. He stressed the need to prove the whole system works - well in advance of the trip!

LRS members Brian Flynn GM8BJF and Briain Wilson GM8PKL made an expedition to Telegraph Hill near St Abbs in Scottish Borders on March 19th to check reception there of the GM8FFX/B 10GHz beacon at 126km near Aberdeen which Brian built and installed last year. They found the signal strength was excellent on this clear sea-path.

They also found a very old but largely-complete wooden radar- or radio tower on the site. Later investigations unearthed interesting theories about its history.
