In this article, I’m going to cover Noise Figure, Noise Factor, Noise Power, Receiver Bandwidth, and how they can affect overall radio receiver performance. Contrary to popular belief, these metrics. read more…
I usually have a respectable HF noise floor at home, for which I count myself lucky in today’s sea of cheaply made switching power supplies. However, we were expecting some. read more…
For a while now, whenever I’ve had my PC on, and I’ve been talking on SSB (several bands), I hear occasional Windows USB connect/disconnect sounds. Generally a disconnect sound whenever. read more…
Amateur radio transceivers demand power supplies which have a large current capacity. The average 100 watt radio transceiver requires over 20 Amps when in transmit mode. Overview A linear power. read more…
