Additional modules of Simple TXCVR and High Current Switch Mode PS

Mike ZL1AXG is building Charlie Morris ZL2CTM’s Simple SSB Transceiver.  This is a modular design and as each module is completed it is tested.   In this second session Mike will discuss design and construction features and demonstrate the testing of completed modules.  The module in the picture is one of two double balanced mixers constructed from scratch on veroboard.

Bernard ZL2BD will present on high current Switched Mode Power Supplies suitable for driving Kilowatt amplifiers.  He designed a system using two SMPS at 24 v to power a 2Kw linear for another amateur.   The SMPS turned out to be very quiet electrically and they are available in 12v and 13.8v and other voltages as well ex China at very reasonable prices.
