January Meeting
Tuesday 5th Jan 2021, 7:30pm
Online by Zoom
"Data Networks and IoT"
Phil Pearson G0UIB

Phil Pearson G0UIB will tell us all about 'Data Networks using Internet of Things (IoT) Devices'. This is all about using cheap devices designed to work with low power sensors etc.

Imagine something you leave in a field and it tells you the soil moisture once a day, so you want it to work on very low power batteries/solar.

To make a digital network which can connect several nodes together, the sensor nodes send data over multiple hops from one end to the other, all cheap to build and low power.

If anyone wants to know more – listen to this talk in January! – online by Zoom

"Forewarned is Forearmed"
By Nigel Newman M0ICH

For February we welcome Nigel Newman M0ICH for an online Zoom talk. Up until the 1980’s the Royal Observer Corps (ROC) underground bunkers were the only means of coordinating the response to a nuclear attack.

Essex CW member and former ROC volunteer (c1976) Nigel M0ICH, will give an online presentation to CARS describing the equipment used and the role of the radio in the event of an apocalypse.

The title ‘Forewarned is Forearmed’…. is the motto of the ROC.

    By John O’Connell M0JOC

    Also, a lighthearted look at the old adage “what goes on tour stays on tour …..”, from an open air concert in front of a submarine in Montenegro, an underground cave in Hungary, The Jazz cafe, O2 Arena and Ronnie Scott’s, to The Albert Hall.
