Wavelength and Frequency can be worked out once we understand the speed of light. By dividing the frequency by 300, we achieve the exact wavelength. Try it yourself, divide 300 by 3.75 and you get 80m. That’s the 80m band. In this video we discuss mains frequency, 3-phase, audio frequency and in particular, the famous 300 – to – 3000 Hz frequencies ideal for communications voice and also sound frequencies. Enjoy!

I know you can buy headsets for a "fiver" but if you are serious, these take some beating. I plugged these into the TS-990s Ham Radio and was quite surprised. NOTE: I have EQ set on my radio for a Heil Headset – there is no doubt I could probably make both mics on show here sound a lot better..! Callum.

Why is aircraft-band on AM? Why do I hear a nasty squeal sometimes when two stations are on same frequency? Why can I hear all the stations on an SSB Pile Up? Let me explain. Callum.
Wow.. This is interesting.. Tilted Ground – or Tilted Antenna. Fascinating experiment! Callum.

CQ DQ.. I fixed my Remote Audio
Well.. I think(!) I have fixed it.. Let’s test it out.
All you need is a cheap USB HDMI capture card and CamDesk (software available on my site) and you can move your front panel or waterfall anywhere you like on your screen. Cool bananas..!
Next time, it’s random numbers folks!
Folks often ask me how we do this live-stream "stuff". Here is a quick explanation – plus some tips you might like. Callum.
