Keith Kerr GM4YXI/GM5X & Chris Tran GM3WOJ/GM2V in Chuuk, Micronesia, April 2015
(It's tough, but somebody's got to do it)!
Well-known Scottish DXer Chris Tran GM3WOJ talked about his DXpeditions to Tonga in 2014 and Micronesia in 2015 (just back!) at the meeting of the LRS on 22nd April 2015.
In April 2014, Chris Tran GM3WOJ/GM2V travelled to Tonga with Keith Kerr GM4YXI/GM5X to activate A35V and A35X respectively. They made 30000 QSOs in a 2-week period.
In April 2015, Chris and Keith travelled to Chuuk in Micronesia to activate V6Z, making 22600 QSOs in 10 days. They encountered extreme weather in the form of Typhoon Maysak which destroyed some of their antennas, followed by a Tsunami warning.

LRS member Brian Flynn GM8BJF talked about The Vector Network Analyzer (VNA) at the meeting of the LRS on Wed 25th March 2015.
The club is now the proud owner of a 6GHz HP-8753C VNA thanks to the generosity of Norrie GM1CNH. Brian GM8BJF is the custodian and "minder" of the instrument. His talk covered the operation of the VNA along with some background on transmission line measurements and a demonstration of it in use. Several members brought along items to be measured.

Brian Howie GM4DIJ talked about and demonstrated Antenna Modelling Software at the LRS meeting on 11th March 2015.
Brian writes: "The design and building of antennas at one time required vast testing ranges with expensive equipment. Analysing and optimising antennas once took many hours of painstaking measurements, hand calculation (if you understood the maths) and modifications with no real guarantee of success.
Modern software now allows you to determine the pattern, feed point impedance and even the SWR of your antenna system before committing to cutting metal or hoisting wires thus avoiding expensive or time consuming mistakes". Full report.
