15/06/2011 - Diode radios - aka 'crystal sets'.

The club invited members to bring along crystal sets that they have built over the years, along with some more modern commercial ones from Tony M0SHA













Roger G4GGI showed a crystal set (Teletron HAX coil and GEX34 diode) and a one valve set he built about 50 years back.

01/06/2011 - Tony M0SHA gave a talk on PAT testing

Tony gave a very interesting talk on PAT testing and demonstrated the BattPAT testing unit.

He gave a demonstration of how to test Class I metal, Class I plastic and Class II devices and what to look out for when making a test such as appliance condition and rating plates.




Please speak to Tony if you require him to carry out any testing for you.
