This video depicts a great solution for lightweight portable antenna deployment.
This is a full kit with all components and a robust case produced by Kanga products in the UK. It costs less than £30.
The components are of good quality and the build instructions are excellent.
It will take you a morning (or an afternoon) to build.
Kanga Products can be found here: www.kanga-products.co.uk/
I have no association with this company, I just like to promote small independent companies in the Ham Radio sector when I am convinced they offer quality products.
It's a fully adjustable End Fed Half Wave Tuner for the 40m through 15m bands.
It will handle 10 watts when correctly adjusted and has a built in SWR bridge with an LED indicator that will 'dim' as the antenna is tuned to resonance.
The trick is to tune for 'minimum brightness' of the LED.
The video, recorded in real time is circa 3 hours long! However to preserve your sanity, certain sections have been speeded up by 20x so it can all be viewed in circa 20mins.
The tuner will work with any QRP transceiver capable of producing between circa 0.5-watt to a maximum of 10-watts RF power.
The video contains lots of tips and tricks for successfully building your own kits, so do watch the 'normal speed' sections :-)

I have been soldering for decades, and I thought the 'Brillo pad' tip cleaning was a great idea. So I gave it a try. I even tried a few different materials from various vendors. But I found that it simply didn't clean a tip as thoroughly as a slotted damp sponge does. I assume the steam created by the hot tip simply boils off the flux residue and oxidation easier and better than the dry cleaning process. So I went back to damp sponges once more. BTW, a good, clear graphic of the schematic of the circuit to see exactly what is being done would be nice.

Morning John I use both! the copper 'brillo pad' and the damp sponge. The sponge for the 'quick wipe' between joints and the copper (needs to be copper or brass) Brillo pad for a deeper 'scrape. Try both and you will have more success. The Soldering 'Brillos' can be purchased form Amazon for a few pounds for a bag of 6. 73 Bruce G4ABX @G4ABX g4abx.co.uk

@@graeme9184 Hi Graeme. I have a couple of LNR precision items: The original Mountain Topper (Brilliant) and a rather bizarre little rig -- the FX-4A (4 band HF TRX) which 'kind of'' works but it more like a bit of home brew kit you need to keep adjusting rather than a real piece of kit you can just use and enjoy! 73 Bruce

sure wish Kanga sold these on my side of the pond - and the qrpkits SOTA tuner is out of stock!

I know. They were my first point of call -- and then I remembered seeing an article in a UK Radio Mag that Kanga were back in business. No hesitation on my part. within 30 minutes I had selected and ordered the Tuner and it arrived 2 days later. Brilliant! When I buy something from the QRPGuys, shipping and tax usually adds about $35 extra. Its crazy! The tuner works well. I've had it on 15M this morning and made a number of CW and FT8 contacts using my KX2 73 Bruce G4ABX

Any chance Kanga might open a store that'd ship from the U.S.? The prices for these kits are great, but the Royal Mail shipping charge almost doubles the price. Shipping within the U.S would only be about one-fourth as much.

I'm afraid it's the same for us in the UK buying from the USA. It cost me $35 to get a $23 kit shipped from QRP Guys. I guess Kanga is too small an outfit right now to think about opening up in the USA. (I have no association with Kanga)
