RSGB Convention lecture 2017 - VHF-UHF DX - the Game of Decibels

RSGB Convention lecture 2017 - VHF-UHF DX - the Game of Decibels.

Ian White, GM3SEK In a talk aimed at all technical levels, Ian explains that decibels are the 'currency' in which we measure our station's performance. We can count our gains and losses, save our decibels or throw them away, and eventually find our own answers to the age-old question: "What is one decibel really worth?" Ian explains why we use decibels; why even 1dB can be worth more to VHF-UHF DXers than almost anyone else; and how 'counting the decibels' can point us to the next station improvement.
