RSGB Convention lecture 2017 - Botswana revisited, A25UK 2017

RSGB Convention lecture 2017 - Botswana revisited, A25UK 2017.

Tony Bettley, G4LDL Tony's presentation looks at the history of the DXpedition to Botswana, their previous visit and why they went back. He talks about the location, resources, actual set up, performance and issues, final statistics, as well as some anecdotes.

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.

RSGB Convention lecture 2017 - M1N-the-Middle, a flexible hardware control add-on for your K3.

James Patterson, M1DST. James has worked on an open source hardware/software project to allow him to take control of his K3 using external add-ons in an interesting and inexpensive way. It is small enough to take to a contest site or DXpedition where you can take your workflow with you.

RSGB Convention lecture 2017 - E51LYC brings Pukapuka Atoll (OC-098) on the Air

RSGB Convention lecture 2017 - E51LYC brings Pukapuka Atoll (OC-098) on the Air.

Last activated more than 22 years ago, this rare IOTA group was in demand by 92% of the IOTA members. The temperature oscillated between 33C during the day and 28C, sometimes higher, with a humidity of 80-90%. Using an Icom IC-7000 with 100W and a multi-band vertical, a total of 5631 QSOs were logged with 3310 stations in 79 DXCCs. About 76% of all contacts were in CW, on all bands from 10 to 40 m, with the rest in SSB.

RSGB Convention lecture 2017 - SDR: The station of the future

RSGB Convention lecture 2017 - SDR: The station of the future.

Software Defined Radio is not new but improvements in design and cost reductions mean that it is rapidly becoming mainstream technology for discerning radio amateurs. SDR is as much a disruptive technology as were the advent of semiconductors or synthesisers. It is said that in five years it will no longer be possible to buy a new radio that is not SDR. We look at what SDR offers us as radio amateurs and what our stations might look like in a few years' time.

RSGB Convention lecture 2017 - HF Propagation at Sunspot Minimum.

When is it? What can we expect? How can we make the most of the HF bands for the next few years as we approach and pass sunspot minimum?
