This is one of the most important concepts in ham radio… the relationship between transmitted power and received signal strength.
Sadly, many hams aren’t familiar with this topic and falsely believe that buying a 1,500 amplifier will make their signal LOUD.
Just because we’re putting out less power, it doesn’t always mean that our signals are weak. If propagation is good, even 1 watt can sound great. Check out these two examples… – Cliff
Are you a new ham who is nervous about making your first contacts?
We’ve all been there, felt that! In this video, I give advice on how to stop putting pressure on yourself. You WILL make mistakes… but, I teach you two words that can help you gather the courage to move forward.
As a bonus, I also teach you two acronyms: “G.O.M.” and “N.N.”
Enjoy! – Cliff
It’s practically rare to hear a morse code conversation where both stations are on the exact same frequency.
This video talks about the concepts behind tuning in CW mode… the carrier, tx offset, and sidetone pitch. Examples are shown using my Elecraft KX3…
If you’re into QRP, I want to encourage you to consider learning morse code. While you can make plenty of contacts with voice or digital, it’s hard to beat the “cw” (continuous wave) mode for efficiency.
With voice, everything you say is stretched out and occupies about 3 kHz of bandwidth. With morse code, that energy is compressed/condensed into a sliver of the bandwidth, concentrating the energy like a laser pointer!
Do you think life is too short for QRP? Then you don’t understand the math!
Cutting your power by a factor of 4 only causes a decrease of 1 S-Unit for the receiving station…
