RSGB Convention lecture 2017 - ZL7G DXpedition
RSGB Convention lecture 2017 - ZL7G DXpedition.
ZL7G, Chatham Islands, was the third DXpedition by the 6Gs Group. Putting on a successful DXpedition requires meticulous planning. This presentation provides an insight into how the 6Gs go about choosing a DX location and planning the DXpedition. It concludes with the sights and sounds (RF sounds that is) from the DXpedition.

RSGB Convention lecture 2016 - Polarisation of 50MHz signals
RSGB Convention lecture 2016 - Polarisation of 50MHz signals.
At VHF we tend to assume that our signals arrive at the other end with more or less the same polarisation as they left with, whereas at HF it’s commonly believed that polarisation is effectively ‘scrambled’ as a signal goes through the ionosphere. But how many of us know what’s really happening to our signals, particularly at the ‘in between’ frequencies like 50MHz? Chris Deacon, G4IFX will introduce polarisation effects and why they are important, and will then describe early results from his ongoing research into the polarisation of real received signals at 50MHz.

RSGB Convention lecture 2016 - The Rise and Rise of 5.7GHz EME
RSGB Convention lecture 2016 - The Rise and Rise of 5.7GHz EME.
Over the last five years there has been a steady increase in interest in 6cm EME operation such that in a contest weekend there are up to 40 stations active. Peter Blair, G3LTF covers the reasons for this growth and describe the equipment of some of the active stations. It will also cover ways of optimising and estimating system performance using sun and moon noise.
