It's fixed. I replaced IC10 which was bad from the first time I applied power. I cut the original one out, removed the remaining cut leads and solder with a HAKKO desoldering gun and tacked in a new O

Hi Hans You may well have already considered this, but once you are happy with the QSX design and are at the point where you wish to purchase components, there is something that those of us who wish t

Hello, I have had some success modifying my three QCX Classics to have AGC to prevent eardrum overload. I've tried to keep it simple and so it uses only 6 additional components, 3 capacitors, 2 diodes

I recently finished assembly of a QCX+ CW transceiver for 20m, which worked flawlessly the first time switched on. Very nice unit and superb documentation, which really makes a difference. However, I

I've made a silly mistake, in the last step when you have to fit the jumper wire linking the top and bottom PCB, I took the dummy load the wrong way round and fitted the wire in the wrong hole short c

Good day everyone. Has anyone of you ever thought of being able to transmit in cw with the Qcx mini from your PC via an interface for digital modes? since i am not an expert with cw v i would like to

I wonder if others have noticed that the clock display on a QCX runs about half a second slow when synchronized with the QLG1 GPS? I noticed this when trying WSPR for the first time recently. I checke

Hello all, I have a QRP Labs QCU Shack Clock that I would like to give away. It is fully assembled and tested and it works perfectly. I have used it with the QLG1 GPS module and they work together. I

I assembled the relay/LPF kit and the signal generator kit. When assembling the relay filter kit I used the default jumper set up. I made 6 filters. Then the manual says to place the highest freq LPF

Just wanted to thank Hans for his brilliant kits, which are filling every spare moment of my time. I've built three so far, every one delivered promptly with no component shortages and excellent docum

Hi, after successful assembly of QCX+ for 20m band, I started reading about new project which is QSX, but last laconic entry is that work is in progress. - QCX+ is a great trx, I have it packed in bac

I'm looking at this kit to fool around with measuring the output waveforms. I already have one synthesizer module in my signal generator and noticed in the pixs of the synthesizer in this kit there is

I noticed the RF output signal level changes a lot when I change frequencies from 5MHz thru 100 MHz. I was expecting the output level to be near a constant level, but it isn't. Was it the BPF assembly

A couple of weeks ago, I decided that I needed to refresh and update my soldering supplies to cope with my forthcoming builds of the QCX+ and other similar kits. After looking at what I already had an
