Signal-Noise Ratio – The Essence of Radio
Discerning signals from noise is what radio reception is all about. We always seek to improve the signal-noise ratio. Read more
Noise Limits Performance in HF Radio Reception
Now more than ever, noise limits performance and enjoyment of shortwave radio listening. Signal strength is one thing, noise is another. Read more
Panadapter Performance – Signal Strength on Steroids
Modern SDR offer panadapter performance that measures signals accurately. See what’s going on at a glance. Read more
S Meter Accuracy – Not So Much Really
S Meters are clever approximations, not precision instruments. Remember that and you can avoid all conversations about S Meter accuracy. Read more
Decibels Make Life Simple for Radio Listeners
Measuring radio signals without dB would be impractical. Decibels make life simple for radio listeners. Read more
Measuring Radio Signals – Old and New
People like to measure things. So, not surprisingly, radio operators have been measuring radio signals since the early days. Read more
Making the Most of Useless Frequencies
Ham radio is about making the most of useless frequencies. And supporting scientific discovery along the way. Read more
Ham Radio Parity is about Antennas
Ham radio parity is a big deal for hams and shortwave listeners in America. Parity makes it easier to use outdoor antennas. Here’s how. Read more
Solar Cycles – Enjoy those Sunspots
I was surprised to see tons of signals on the 15 meter ham band this weekend. Solar cycles effect how well radio signals propagate, and latest cycle has not been very good. Read more
