TRansmitting from Honiley in Warwickshire across ther shortwave bands. Using callsign M0XXT. Tune in, join the chat or see if you can reach me? Lots of fun today (I hope!). Callum.

How do you manage an accidental Pile Up on ham radio? I have a technique! Let me know what you think. Callum, M0MCX.
In this (Live) video, we will look at:
What is a Dipole
Coax or Balanced feeder
How they work?
Dipole or Doublet
Do we need a chokeChoke
How do we connect to the feedpoint
Shapes, Flat Top or Inv V – and Z shapes etc
How Height above ground changes tune
What happens to your signal (when we change the height)
Enjoy! Callum.
Ham Radio Antennas normally work better at height. The Hexbeam is no exception and although a result can be achieved from about 6m AGL, for the 20m band – we ought to be looking at least around half a wavelength. Let’s have a look at the problem and understand the physics. Callum M0MCX.
People not hearing you on Amateur Radio? Maybe I have the answer. Callum.
Anything can happen – and it often does! See if you can hear me, join in – or just chat on the live-stream live-chat. Enjoy and have fun!
Ham Radio Signal Reports – Maybe we’ve got it all wrong? Let’s find out! Callum.
My Holiday Ham Radio Antenna. NOTE: I used a Classic Stay-Up kit as an experiment. These are not normally supplied but I was away for 2-weeks and was running some tests with a number of different clamps. TWO are normally supplied with the DX Commander Expedition Kit as at June 2022. Price for the Expedition antenna is currently £209 and gives me 40, 20, 17, 15, 10 and 6m (No ATU). Tom M0RMY put his up (and down!) every day when he walked around Isle of Arran with this and the IC-705, solar power and a battery. He says he got the erection and tear-down to around 7-minutes. Tom’s channel is: https://www.youtube.com/channel/UCW3uOTzOtgMMa8p6oKeXYXw/videos – Check out the little Easter Egg at 5:54 (drone!). Thanks to everyone who joined in! 73, Callum, M0MCX.
Last Stream from Cornwall. We pack up today and get back to work for Monday. Start on 40m but looking for DX also on 20m band. See you there. Callum.
This follows the Premiere where I discuss extremely long (very long!) wire antennas. Q&A followed by some reall RF from Cornwall using TS-590SG at 100W and DX Commander Expedition. Logging is via N1MM+ and the little spectrum thing is Friture (free download). Callum. M0MCX.
