About Hans
Hans graduated with a physics BSc in 1993. He left his 22 year career in investment banking software development to pursue QRP Labs full time in 2016. The operation is now based in Turkey where Hans lives with his XYL and their three children. QRP Labs has grown rapidly to become a well-known name among QRP, portable and home construction groups of amateur radio.

I have built the dummy load kit and was more than a little impressed because it does relative power measurement with only the lowest-price multimeter. I made that to test a different preassembled kit that I bought used. Figured it may come in handy with the QDX low bands. My daughter helped sort count and hand out parts as I needed to solder them. We had a blast. She was inspired to make a hobby of just building and and reselling them. (She was brand new to radio just passed her Technician class exam. Her birthday and the ARRL Field Day happened one after the other. Her birthday present last year were to assemble parts of a portable station to speak with an ISS astronaut. Competition didn't allow a response and the cross band antenna tired her more than expected. Still. So we assembled the QDX right after the dummy load kit right after the field day. Really nice start. You got credit as you rocked her world for a while. So maybe there are dads everywhere to thank you.
Thank you so much to RSGB or this most informative chat with Hans Summers. And thanks to Hans for all you do for amateur radio ! - Bill, W3WJ
Thanks Hans for your amazing kits. Following the build of 4x QDX, 1x QMX,I start the build of my QMX+ today.
God bless you! Love your work 73 de VK2AOE
Thank you Hans - a most enjoyable and informative talk. Look forward to finishing my QMX+ and getting it on the air and of course to all your future upgrades and kits. 73 Stewart/G3YSX
Watched last 30 minutes, shall be seeing the rest.. very informative.. built 3 of Qrp labs radio kits no problem, use them to great effect, receiver side is excellent very quiet, only use simple dipole, matched for best SWR using a nano VNA, as I used same during construction..
Excellent video and thanks for Hans for those excellent kits. I enjoyed making a QCX and a QCXmini and also I am enjoying using them. The question of using more than 12V is not about the output power but about using a 4 LiIon or LiPol in series, I think. 73 de YO3HJV
Do the RSGB do anything for Amateurs that are suffering chronic interference, answer NO that's why I have ended my subscription. Yes men for the incompetent Ofcom goons
Hi Hans, Any chance you can come up with a development board that features an audio amplifier capable of driving an internal speaker mounted to the top case cover? That would be great!
