Recently I came across W5KUB´s review on switching power supplies on Amateur Radio Roundtable. In this case he reviewed the 30 AMP Jetstream JTPS32MAB 12V switching power supply. These units are sold for a fair price compared to many others on the market. I decided on this one and it´s on order since the review implied the unit is very quite while running. I will post my personal review later down the road.

The Sony ICF-SW77-World Band Receiver
Image
As an alternative to professional wide band HF receivers, this old timer the Sony ICF-SW77 is a great performer. I acquired one who needed a minor repair and gave it test on the 80 meter band using a tuned wire antenna. The results were amazingly good. More on this receiver on Media Wave Circle.
Back to the mid 80´s

Recently I acquired a President Grant AM/SSB DX radio from the mid 80s. What was special about this radio was it´s pristine condition. I have to admit I was struck with a little nostalgia but the radio is a keeper. The above picture displays the actual radio in the shack.
