I have built 7 QRP-Labs kits and I always use an Exacto knife to scrape off the enamel by running between my finger and the blade.

Ted, I agree. I like these rigs enough that I have 2 of them and will buy more stuff here. But that doesn't change the fact that using an audio connector as a power connector is not good practice. I

If is all ok, why i can't adjust IQ balance, Hi and lo also. my power output also low, less than 1w. where i should look for? De 9M2KLH

For larger diameter wire, I scrape and sand off the enamel. And I remove enough enamel so I get a good solder joint on both sides of the thru-hole via...

I have to agree with Ted. If one wants all the features Laszlo mentions, one can always type Yaesu or ICOM instead of QRPLabs on the browser. This is a hobby. 73s Felipe

I have to disagree. QRP-Labs designs AMATEUR radio kits with amazing performance at very reasonable prices. In particular, the mini was a requested reconfiguration of the QCX for minimum size as was

Those voltages are all good. Those are the voltages you should get with your external DVM. The voltages on the chart are what you should see if you use the on-board DVM which has a lower impedance and

Thanks Alan, you got there before I did.

Enclose are my measurement. Is it IC 8,9 &10 need to change?? Thank DE 9M2KLH

Graham, I know Hans likes this method, but if you try this you will never go back... https://groups.io/g/QRPLabs/message/61179 -- Cheers, Chuck

What power out?

Laszlo This is a hobby. Hans is not designing avionics or medical technology. He is producing a ridiculously feature-rich transceiver kit for a fraction of the price of a shelf bought rigs. QRP labs

Thanks Roelof, I'll get hold of the parts and give that a try.

Happened within 8 hours again. Different symptoms.

At the risk of offending someone (which I'm really not trying to do) this is a design error on multiple levels. Stereo plugs are not designed to be power connectors and it was misguided to use them as

Thank you Dan, I did kick myself when I spotted my soldering mistake! That's just it, I'm fairly newly qualified as you might guess by my call sign. QCX+ is the first proper radio kit I've built (I've

A better probe, with more accuracy, is a steel or stainless steel pin, as used in dressmaking. Solder a wire to the head. then cover with heatshrink laving a millimetre or so uninsulated at its

Hi Ian I have to completely agree with Alan. If you fault find your way through it you might find that the solution is just one faulty component. If you have never done fault finding before it is fun

Hi Set a value in the park frequency, I use 27.065 MHz, my first walkie talky was in the frequency in the 60's! CH 9 CB 73 Andrew

Hello Mont, all A reminder that curing drift on an Ultimate3S is possible, at least to a large extent, by other methods than a TCXO - and that this was described in an age old App Note I wrote back in
