Synchronized Switching Relays in Action
So, here it is. My dual channel antenna switch built and working in the lab. A project of synchronized switching relays. Read more
Diversity Reception Antenna Switch
My first attempt failed. My second attempt to build a diversity reception antenna switch will work! Here goes. Read more
Using Your Antenna Multicoupler with Several Receivers
My 8 channel antenna multicoupler, receive only, is back in use and performs magnificently for receive use. Read more
Using Loop Array with a Single Channel Receiver
So how do you use a wideband loop array with a single channel receiver? With a receive antenna phasing controller, of course. Read more
Tracking Down Antenna Switch RFI Ingress
Well, it’s settled. I have a major antenna switch RFI ingress problem. As much as 30 dB on some frequencies. Sigh. Read more
Antenna Switch Port Isolation Considered
My homebrew antenna switch port isolation is decent, but not great. But too much RFI is being fed though the outputs. Read more
SDR Antenna Switch Up and Running
My remote control SDR antenna switch is up and running. Now, I can switch SDR and antennas by remote control. Read more
Dual Channel Antenna Switch with Relays
My homebrew dual channel antenna switch is up and running. It let’s be switch pairs of antennas to a bunch of two channel diversity receivers. Read more
Homebrew Radio Switching Board
I am moving a large part of my shack to a wall mounted radio switching board. My goal is complete remote relay switching of antennas for my diversity receivers and loop array. Read more
