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.

04/05/2011 - The club hosted another of our popular show and tell evenings featuring:

Andy M0ULF - Digital power/swr meter kit

Tony M0SHA - Collectable TV sets - Sony TV9-90UB (displaying 405 line picture here) and Sinclair Microvision MTVB1

James M0VLF - VLF power oscillator with heating effects

16/02/2011 - Homebrew Antenna Tuner by James Sales M0VLF

James, M0VLF, gave a brief talk on the construction of his homebrew antenna tuner for HF.

This has been tested and has showed promising results, and only requires an air spaced coil, tuning capacitor and a rotary switch - the most difficult and expensive part to source is the enclosure itself!

M0SHA has a circuit diagram available for those interested in this easy to build tuner.

Feel free to contact James or Tony for construction / design tips at one of the meetings.

02/02/2011 - Optical Communications by Tony Fell M0SHA

Tony, M0SHA, kindly gave us a very interesting talk on optical communications using a homebrew tranceiver which demonstrated the design , setup and operation of the mode.

He also had a very interesting display of various optoelectronic devices that can be pressed into service to produce a good quality piece of equipment for DX work.

For those that are interested in building such a device, please contact Tony directly at one of the club meetings.

OUR NEW LOCATION!

From Wednesday the 6th October the SHARES meeting venue will be at the recently constructed building to the right side of St Andrews Church in Maple Road, Surbiton KT6 4DT.

This meeting will take place in the Blue Room accessed through the front main entrance. Everything is at ground floor level.

We have been asked if it was possible to move our meeting dates to the first and third Thursday of each month, which would make the following meeting on the 21st of October. Please email if you would find this inconvenient.

Our new venue has limited off street parking, but there is a local car park at St Philips Road, a short walk from us via St Andrews Road, and this is free after 18.30pm.

Please look at the map to see the locations mentioned.


Topics for the next meetings will be decided shortly.

SHARES Field Day

We have use of a field planned for July, and propose the weekend of the 24th/25th
This will give us two days with the opportunity for those who wish to camp overnight. And for others the opportunity to visit on either or both days. For those who have been before the site is about 30 minutes drive down the A3 and there is also a rail link (Weekend timetables permitting)

We already have the G5RV in place so some of the set up work is done.
We have a Gazebo, generator and table and we should be able to operate on all of the HF bands.

For your own comfort you may wish to bring some refreshments, a seat, tent etc (if you want to camp overnight)

There is a pub down the road which serves food but it can be expensive so bringing a pack lunch then having a pint in the pub may the cheapest option

- The site can be accessed by car and is a short train journey from Surbiton Station.

For those with cars we will meet at the club at 10:45 for 11:00 departure.
If you have space in your car for equipment and or passengers please let us know also if you would like transport.

Here is a map showing directions -



When you arrive the field is accessed by a locked gate. If you arrive by car and the gate's locked park in the lane and ask Tony who can let you in. We will keep the site locked to deter unwanted guests



Those arriving by train can take the footpath running by the railway from Horsley station

Our next meeting is on Wednesday the 12th May.

The meeting will include pictures and video from the recent club trip to the Wireless
Museum.

The usual refreshments will be available.
