Down Memory Lane: Variable Power Supply Project by Chris Meyer ZS1M - June 2003

Image:  Chris Meyer ZS1M  (Click on image for larger view)

Chris Meyer ZS1M a well known radio amateur in the Southern Cape constructed a 0 - 30 Volts, 20 Amp Variable Power Supply in June 2003. Looking at the photos this is a very neat and well constructed power supply by Chris ZS1M.  Although Chris is not active on the airwaves anymore, he was always a good source for various types of components and old used radio equipment. Sadly time moves on and Chris disposed of all his surplus components and equipment.  Chris was also instrumental in obtaining a permanent repeater site for the 145.600 Mhz Repeater on the Dana Bay water tower.  No wonder the 600 repeater was known as the Dana Bay Repeater.  This repeater played a instrumental roll for many years in the Mossel Bay area.

Apart from the amateur radio hobby Chris also wrote several books relating to genealogy especially related to the Meyer Family. Chris also documented information about many local cemeteries in the Mossel Bay district. He also wrote a booklet about the history of the Garden Route Radio Club. 

Best wishes goes to Chris ZS1M and Bets his wife during their Golden Years.

Christi ZS4CGR enjoy playing around with all types of antennas.  Mostly all of his antennas are "home-brewed" and they work great and in some cases even better as store bought antennas.  This time around Christi decided to construct a Mag Mount Multi Whip VHF/UHF Antenna that  works on multiple frequencies.  He is still busy "playing" around with the antenna and a followup article will be published once all tests have been completed.
