The Astron SS-30M power supply.


I picked up the new power supply last week on Friday from the post office just in time for the CQ WW CW DX contest. The power supply I ended up choosing was the Astron 30 amp switching power supply. Yes I wandered away from the linear power supplies and into the dark side of the switching power supplies. The supply had very good reviews and now that I am on a fixed budget the linear supplies were just a bit to high for the budget. I have been using this supply for over a week now and am very pleased with it. There is no"hash" from this supply that I have read about online with other switching supplies. I have used it in the CW contest and also this week on FT8 and it has not heated up at all. After repairing the Astron RS20 I decided to keep it as a back up supply just in case the new supply in the future lets me down.....BUT when I do use it I will keep its duty cycle in line to what it has been designed to handle and not what I was putting it through.
