RSGB webinar Tonight@8 : How to get started in software construction

/in , ,

How to get started in software construction and where it can lead you  –  Heather M0HMO.

 

 

 

All you need to get started in Software construction is a personal computer (Windows, Linux, Mac – they’ll all do), some spare time and, if you want to make a ‘thing’ then some loose change.

There are three easy and virtually free routes into writing your own programs: develop applications that run on your PC using the free Qt environment; write programs to run on one of the Arduino boards (£3 from China plus a USB cable) using the free Arduino application; or go for the middle ground with a Raspberry PI (around £40) and a wi-fi connection.

Heather will take you through the setup for each of these and show you just how easy it is to go from flashing an LED through developing an ATV receiver to producing a fully-featured windows PC application such as her Mapper entry in the RSGB construction competition.

RSGB webinar Tonight@8 : Using Pluto and RPi4 for ATV and narrowband

/in , ,

Using the Pluto and RPi4 for Amateur TV and narrowband  –  Noel G8GTZ.

 

 

 

 

Following on from his “Advances in Amateur Television” talk at the 2017 RSGB convention, Noel Matthews, G8GTZ will be presenting on the latest developments in the ever-evolving world of Amateur TV.

Noel will give an overview of ATV activity in the UK and in particular how the use of Reduced bandwidth (RBTV) signals has enabled ATV QSOs on the lower VHF bands. He will give an introduction to the QO100 geostationary satellite which has enabled QSOs with fellow DATV operators as far away as Brazil, India and South Africa.

Noel will also be describing how the development of Software Defined Radio (SDR) based hardware and powerful single board computers such as the Raspberry Pi has revolutionised the development and capabilities of amateur radio dedicated products.

He will describe how it is possible for radio amateurs to build an advanced touch screen multimode narrowband and Digital ATV transceiver covering 50 MHz to 10GHz for under £350.

RSGB webinar Tonight@8 : Repeaters

/in , ,

Repeaters: how they are built, planned, commisioned and used  –
Steve F4VTF/G8SFR

Voice repeaters have been with us in UK for almost 50 years a lot has changed in that time. We all are aware of repeaters but how many of us have considered what’s involved in getting one commissioned?

In his presentation, Steve will cover a wide variety of information about repeaters, including the following:

  • What is a repeater, even in its most basic form?
  • What is required to put a repeater on air?
  • Are all repeaters connected to the internet?
  • Is it important to support your local repeater group?
  • Don’t just listen….put out a call, respond to other people’s calls even if you don’t know them!
  • Is a Simplex Gateway an alternative to a voice repeater?
  • What does Emerging Technology Co-ordination Committee(ETCC) do?
  • Where can you find out more information

Introduction to Meteor Scatter communications  –  Gavin MM1BXF.

 

Have you ever thought about making more QSOs over a longer range on VHF? This talk will give you the background on how to achieve that through bouncing your signal off meteor trails. During the talk Gavin will show you how and why Meteor Scatter communications work: what software you should use, how you should use it, and when you should use it.

 

He’ll also look at what tools are available to help you to maximise your QSO count.

RSGB webinar Tonight@8 : EMC/EMF regulering in UK

/in , ,

Assessing your station against ICNIRP EMF levels  –  John M0JAV

Ofcom is implementing changes to all transmitting licences to require licensees to comply with ICNIRP general public limits on EMF exposure. This will include previously licence exempt users who transmit at powers of more than 10W EIRP. John will introduce the work of the RSGB and ARRL experts in assessment of exposure to EM fields.

RSGB responded to the Ofcom consultation (on behalf of UK amateurs) and we are now preparing guidance on compliance with the new requirements. The talk will outline these requirements and introduce four ways to conduct and record the results of the assessment include calculating required separation, use of known compliant station configurations and potential mitigating actions.

The Sherwood Ratings: Transceiver Performance for the HF DX & Contest Operator , Rob NC0B

 

Rob Sherwood’s name has become something of a standard in the radio amateur equipment world as a trusted comparison guide to the technical performance of a wide range of transceivers.

 

This presentation will explain the process that Sherwood Engineering go through to produce detailed performance figures for a wide range of transceivers. Rob will talk about the acquisition of a true random sample of the radio, through to the technical processes of measurement and the compilation and presentation of comparative results.

The presentation will also include details of Rob’s recent findings on the long awaited new Elecraft K4D.

Rob will also talk about how modern receivers have become very good but how generally many transmitters need attention to some aspects of their performance.

RSGB webinar Tonight@8 : Discover more about ARDF

/in , ,

Discover more about Amateur Radio Direction Finding  –  Bob G3ORY


Bob takes a look at Amateur Radio Direction Finding (ARDF) from its start in the UK prior to World War 2 to the situation in 2021 where there is a worldwide structure, competition format and rules. It covers the legal impediments to running DF hunts using cars, the frequencies, competition formats and the equipment needed for 2021 ARDF.
There will then be a sequence of videos showing someone competing in a 144MHz event which shows not just the taking and plotting of bearings but the whole decision-making process that results in locating the hidden transmitters rapidly. It is the challenge of this process that can make ARDF so enjoyable. The webinar will also feature contributions from Kim Taylor, M0KNV giving the perspective of a regular Club member being talked into trying ARDF and from Flora Jolly who was persuaded to go out and try ARDF with her Dad David, M0JCO. The presentation wraps up with a review of ARDF coverage across the RSGB Regions and the steps currently being taken by the RSGB Board and the ARDF Committee to make provision for ARDF in all regions.

RSGB webinar Tonight@8 : Radio construction

/in , ,

Amateur radio construction  –   Steve G0FUW and Pete N6QW

 

Despite what many people think, building your own radio equipment is still a very popular aspect of amateur radio.

In fact there has never been a better time to do this, with readily accessible building blocks and high spec test equipment available at bargain basement prices, or, in the case of software, absolutely free.

This presentation covers the reasons why people homebrew radio equipment, share some ideas on how to get started and provides some examples of homebrew gear, and using hardware and software.
