Shed Workshops

Shed Workshops: An introduction

Several members are proposing to offer Regular Shed Workshops. These provide an opportunity for amateur operators to work on some interesting small projects together while sharing technical experience and ideas.  Anybody would be welcome to participate (i.e. they are not limited to members).

Each workshop would have a nominated lead and be held in someone’s garage or shed. The workshops would usually focus on a specific topic or technical activity, although this would not prevent anyone introducing unscheduled topics at a workshop. Workshops may spin off projects, where a series of workshops are focussed on construction of something of interest to attendees (or a group of attendees). Donations may be requested to cover consumables/projects.

Suggested topics for 2018

These are not in any particular order – choice of topics would depend on interest:

1. Transceiver and Linear Amp testing: Two tone tests (SSB) and power measurements. Using RemoteDX Inc Remote Station equipment for demonstration.

Lead: ZL2BD, Location: 1 Winsley Tce, Churton Park

2. Kitset Transceivers: Build a Bitx40 (US$59) or uBITx (US$109)

Lead: ZL1AXG, Location: 2 Derry Hill, Churton Park

3. Active receiving antenna: Build a simple 500kHz to 30MHz Active Whip receiving antenna and test it.

Lead: ZL2BD, Location 1 Winsley Tce, Churton Park

4. Part 1: Audio Projects: Show and tell. Hifi audio and bluetooth systems. Headphones and headphone amps. Instrument and guitar amplifiers.

Lead: ZL2BD, Location 1 Winsley Tce, Churton Park

5. Part 2: Audio Projects, Class D Audio amplifiers: Modules and home assembly of High power Audio. Demonstration of power output measurements on a class D audio Amplifiers.

Lead: ZL2BD, Location 1 Winsley Tce, Churton Park

6. Magnetic loop Antennas: Practical Construction techniques, Demo and tests on a mag loop installation.

Lead: ZL2BD, Location 1 Winsley Tce, Churton Park

7. Baluns, Ununs: end-fed matching of suburban antennas. Demos and measurements.

Lead: TBA, Location TBA

8. Simple Antennas: Build a dipole, end-fed antenna or windom, multi-band dipole, etc.

Lead: TBA, Location TBA

9. Power Supplies: switch mode and analogue. Show and tell. Checking for hash and filtering techniques.

Lead: TBA, Location TBA

10. Antenna switching: Practical demo using auto relays. Building techniques. Automation using band switching signal from transceiver. Testing Isolation between ports. Kitset or project build potential will be discussed.

Lead: TBA, Location TBA

11. Multimeters: Old and modern show and tell. Checking accuracy and meter calibration.

Lead: ??, Location TBA

12. Antenna Tuners: How to build your own Pi tuner. Air core coils vs torrid inductors. Partial automation using band switch signal from transceiver. Full automatic tuning and how it works. Demo with the club 1kW tuner.

Lead: TBA, Location TBA

Workshop format

The proposed normal duration would be 2 hours. A timetable of times and dates will be developed after feedback has been received. Each workshop session would have a nominated lead/convenor who sets the agenda and timetable as appropriate. Bernard ZL2BD and Mike ZL1AXG would kick things off.


Feedback

We have created a short survey to identify those interested in the Shed Workshop sessions and preferences as regards day of the week and time.
