Ham Radio-QRP rig comparison, FT817 / X108G / X5105 / mcHF RS-918, Ham radio review

Hello all and thank you for your support! your comments and suggestions are very complimentary and they keep me writing this website which is primarily Ham Radio, but it also highlights my other passion which is ART, producing realistic portraits of children, parents and of course dogs.

I enjoy QRP working on HF mainly CW and thought I would share this video which is a demonstration of a number of low powered HF transceivers currently on the Ham radio market, you can watch this video to ascertain which is suitable for you.

QRP, in my opinion, is 5 watts and under, using low power on the HF spectrum needs a resonant aerial its not much fun calling CQ endlessly with 5 watts or less into a poor aerial and getting replies, your aim is to transfer all of that power into your radiator. 

Resonant dipoles work very well when placed at a minimum of a half-wave above ground, my particular method of feeding the dipole is via twin lead, 75-ohm cheap bell wire works, I have also used the popular red and black power cable to feed an aerial, a suitable !:1 choke connected with a short length of coax to your rig works well.

I have personally used quarter wave radiators with 16 radials on QRP and found that my signal was being received very well over thousands of miles, vertical aerials have low angle radiation patterns needed for DX operation.

Thank you for reading my posts, please share and keep commenting, they all help to educate me and the many new people who read this website.
