Mid-Ulster Amateur Radio Club in the north of Ireland hold online ZOOM presentations every few weeks which they then post to their YouTube channel.
This week, they had a presentation by Dick Pasoe, G0BPS about the history of QRP (low power) radio operation.
Many radio amateurs prefer the challenge of building their own low power radios and have the satisfaction of using something they built themself rather than buying a 'plug n play' commercial radio.
The video gives a general overview of what is involved.
