20 March meeting:  Assembling some basic test equipment

13:00 – 15:00 ZOOM meeting due to Omicron:

Bernard ZL2BD and Mike ZL1AXG gave a Zoom talk on assembling a basic set of test equipment to support  typical operating and antenna and equipment construction projects undertaken by amateur radio operators.   This equipment is so very affordable today.   The talk discussed relative priorities for purchases, and how to avoid making costly mistakes.

Shed Workshop on 6 March: The ZC1 test jig & a replacement vibrator

For anybody who has been around in amateur radio for a while, the ZC1 will be well known. It was developed by Collier and Beale during WW2 for use by the NZ armed forces. As it covered both 80m and 40m, it was highly prized by hams, in an era when commercially made equipment was hard to come by.

On Sunday 6 March 2022 Bernard ZL2BD gave a talk (on Zoom) on a ZCI test jig that he built, and has used to test the working of several ZC1s. The club owns a ZC1 that is for sale to any member interested in purchasing it and was tested using this test jig.

Bernard also demonstrated a replacement vibrator that doesn’t require modification of the ZC1 power supply. He is still working on variants to perfect this.

11 members and visitors joined in on the Zoom session, which was very well received by those attending.
