Wow! It sounds absolutely fantastic. Can't wait to get one. Well done Hans - all your efforts are greatly appreciated. 73 Brian G3ZOH

Hi David. On the 20 Meter version, some folks find that removing a couple of turns from L1, L2 and L3 will increase power output, if the issue is a lower than expected power output due to lower than

Across the resistors Evan, before the diode. David G4DMG

David, Where are you measuring on the dummy load? If across the resistors and not the power tap, then your power measurement is correct. If you are using the Power Connection on the dummy load, that

Very exciting. Just read the full description including photos and sports car and sunglasses. I know a CW bicycle mobile practitioner who will benefit. (Not me!) Dave

Hi, Filing a nut to get it to fit is good practice for scratch building gear:) 73, Bill KU8H bark less - wag more

My 20m QCX+ is working quite happily albeit only on receive so far. I have been measuring the output with a scope across the QRP Labs Dummy load and with a 12 V supply I am seeing 23.2V peak-to-peak,

Once it is assembled as best as you can get it, You will never notice it.

Thanks much. I did take your advice but still had to file the nut to get it to fit. All ended well. 73

Hi all Some of you may have been waiting for orders involving any of: QCX+ QCX+ TCXO Ultimate3S VFO Clock Si5351A Since we had at various points in the last week or two, ran out of these kits. The

Hi K3YV This is normal. And not as bad as you say :-) I was constrained by the dimensions... the necessary relative positions of the LCD and the rotary controls just left very little room for that

Enlightening and very comprehensive progress Hans. Thanks for all your hard work on what looks to be an awesome radio in the ultra compact QRP arsenal. Cheers, Jules - G4UET

I just finished the 40m QCX+ radio. I had problems assembling the read-out circuit board. 1. The trouble was with the nylon nut (andblack screw) located near the volume control. The nylon nut was

You and me both Hans. Sounds excellent! 73 de Rachael M1AYG

Hi all I am excited to provide an update on the QCX-mini project http://qrp-labs.com/qcxmini.html Again to stress: QCX-mini has the same schematic (almost), firmware, operation and performance as QCX

I haven't yet done an exhaustive evaluation, but when I turn the amp on and off I don't hear any change in the noise floor. Steve N9SZ

Hans, that makes more sense. Sorry, didn't mean to imply anything negative about QA other than it might have been tested in an 80m unit before shipping. And now that I think about it, that doesn't

Hi Mike No chips are ever supplied pulled from any build :-D I expect you had some intermittent connection somewhere and just tapped the left button at some point; though nothing was displayed on

How much RF noise does it produce? Tnx de Arnie W8DU
