The ZS1I 40M WSPR Beacon has been off the air for the last two weeks due to the failure of a cheap 220v AC - 12v DC switch mode power supply. I opted not to replace the power supply with another switch mode power supply. I decided to go the solar power supply route and constructed the above supply for the beacon.
You might ask but why such a tall format solar power supply. As usual I use what I have available in the junk box. This power supply can also be used as a all in one supply. The solar panel for the beacon is installed outside apart from the supply itself but if I want I can add the panel to the two aluminium stays at the back of the supply. The solar supply can then be moved in the direction of the sun but not only that the operator will have access to the solar controller display information at any time while operating his radio from the supply.
There is really no need to explain how the solar power supply was constructed. The photos below provide you with more than enough information to build your own. Remember to add fuses on the input and output of the supply should anything go wrong.
Herewith further information about the power supply:
The WSPR Beacon is now back on the air and running of the solar power supply. I am monitoring the beacon as well as the solar power supply to ensure that the beacon is now functioning optimal again.
