My order is the 30m version and my number in the middle of list is not shown so guess no building for me during the Christmas break. David VK2JDR

They are just crediting me as the "photographer" if you could call me that hi hi. 73 Hans G0UPL http://qrp-labs.com

Klaus, I'm not so sure. Possibly the best way I have for removing that sort of device is an embossing tool. (Cheap hot air gun.) Cut a hole in some tinfoil the size of the chip, heat it and lift

I am feeling with you. You should really check clock 0 and clock 1 with a scope. If you have a two channel scope, you should even observe the 90° phase difference between the two clock outputs of the

Hi Jerry ?I am sure you mean QCX, not OCX. My answer probably will not help you too much, but I have made the same observation like you: As soon as you activate the RIT by double clicking the

I double-click on left button - RIT is engaged and I can tune it.? But rig will not transmit when key is depressed. Rig works in split mode. nice rig - powered it up yesterday for first time...and

Hi Hans, Thank you for update.? Mine is in that list. Cheers and 72/73 Ray VE7AVG

Peter, feel free to contact me direct with any questions. Always happy to help another ham, as I was helped when I started this journey. Mark Lunday, WD4ELG Greensboro, NC

Thanks for the update Hans. 73 Tim KB2MFS

Hi all I updated the QCX page with what I hope is a clear status. http://qrp-labs.com/qcx 73 Hans G0UPL http://qrp-labs.com

Found this note from Hans. The amp in the U3S is probably more Class C than D. The 3.3V pk-pk squarewave from the Si5351A probably isn't enough to hit the BS170 hard off/on. So I think optimistically

Thanks Mark for the info.? A googling I will go.? At least I understand that. Peter

You might want to take a look on Amazon, I've already found a pack of replacement screws for the enclosures, they also sell boxes with a large selection of transistors, resistors and capacitors, it's

Well...? so far I have incorrect voltages on pins 5 and 6 of IC5 (both less than half of what they should read), and no output at all on CLK0 and CLK1 using the onboard counter function and my bench

The U3S has bias on the Mosfet(s) so is that class D? , surely notcheersGeoffGI0GDP

Do you have the PPS pin grounded if you are not using GPS. Also the crystals do seem to drift. Put a TCXO in one and it is much much much better. I did have one with crystal jump 1.4KHz for no

I have the receiver module and using ProgRock as LO.? Using serial port interface to change freqs.? I have set reg 2 to calibrate LO output freq in the past and all worked fine. Today I noticed that
