Rodney’s talk on Electronics at the Taplin Centre 27th August

August’s meeting was a talk by Rodney reminiscing on over 25 years service at some large laboratories near Redhill (Surrey), formerly Mullard but later taken over by electronics giant Philips. It was a multidisciplinary establishment also employing specialists in chemistry, metallurgy and mechanical engineering.

The presentation focused on a wide range of specialised scientific measurements used in the assessment of novel components, circuits and systems stretching far beyond those regularly used by radio amateurs. Numerous interesting questions from the audience rounded off a very enjoyable evening by highlighting occupational experiences of some other club members.

Talk on Electronic Components and Circuit Assessment

Rodney has been busy preparing his talk for the monthly Taplin meet being held on Wednesday 27th on the subject of Electronic Components and Circuit Assessment which will no doubt prove to be an interesting and educational evening.

The doors open around 7.30pm as usual and given the Wx’s turn for the worst in recent days you may want to leave that little bit earlier and ensure that your drive to the club is a safe one. The roads are particularly wet at the moment so be careful.

See you on Wednesday!
