I was given one of these DIY tuner kits.
US $11.55 12% OFF|DIY Kit QRP manual days Antenna Tuner Tune 1 30Mhz For HAM RADIO * CW -in Frequency Meters from Tools on Aliexpress.com | Alibaba Group
My hands arn't much use these days, so got a family member to assemble it & didn't make a bad job either.
I wasn't expecting great things from it, but as I only receive I thought it might be of some advantage.
So far I have tried it between 5MHz - 9MHz on a end fed longwire & it does filter out some of the muck during the day.
Reading some of the reviews on it sugest it isn't designed very well & would work better with different value componants.
I didn't find any sugestions as to what these changes would be.
