The values are all in the assembly manual but they're not summarized in one place, they're given at the points where you install the components. The BOM just says "varies by band". You can see all

Do you mean libusb0.dll ? Just Google with that filename as search argument and you will get a load of hits to help you. (seems to be a USB driver issue ...) -- Regards/73, Enno, PF5X

Hi all, I received the replacement controller today and did some quick tests. Reverse Beacon network shows that the QCX is working nicely :-) Power output between 2 .. 4 watts and antenna Cushcraft

Hello all. Enjoying my QCX on 40 metres. Trying to upgrade firmware to 1.00c, using the How To document. But when I try to run AVRDUDESS, I get the error message "The application has failed to start

I have not yet the kit but the case recommended by pd7maa, if there is no place I suppose that we must replace the green connector by another style ft817 or ic202 .

Thanks very much Hans. I hesitated to contact you direct as you are so busy. That is helpful. Keep up the good work! 73 Brian G3ZOH

I'm patiently waiting for the 40 meter version I ordered way back in August. It looks like shipments have stalled again on these.? I have a very well equipped stock of toroid cores, resistors and

Mine fits nicely under the display in the upright position Marc

Oh thank you so much. I was wondering what else to check. My problems are now confounded after reflowing solder joints and now only getting error si5351a. I am so frustrated.

Hi Brian The physical specification of the 470uF capacitor in the subsequent batches of kits is 6mm diameter, 7mm height. 73 Hans G0UPL http://qrp-labs.com george.familyuk@...>

Hi all There's a new video published today by Kevin KB9RLW reviewing and demonstrating the QCX. There are now several videos about the QCX, and to make it easy to find and watch them I have put them

This is a trivial question but the answer would be useful. Message #17075 advises that electrolytic capacitor C47 should be mounted horizontally in the first batch of QCX kits as it is slightly too

Thanks Greg I have started a new web page http://qrp-labs.com/qcx/qcxgallery.html for builders' photos, to give people ideas about how to enclose their QCX radios. 73 Hans

Hi Michael I assume you have built your clock using a 4-line display, not the supplied 2-line display? To alternate between different displays on a line, you should enter the text for the line with

Oho!!!! I installed it back the front!!! It protrudes much off the board when installed correctly. You cannot poke wires in the back of it LOL Thanks folks!

Hopefully the metal inside hasn’t been damaged. When I inserted the wires, I just poked them in until they stopped and then tightened the screws. It’s a compression fit. Is the block installed

HI, thanks Mike and Marc, but even with screws fully loosened, nothing gives way. The silver metal inside does not move, even when pushed down or in with a toothpick, screw driver, test lead end...

Hi Just loosen the screws on top Them poke the wires into the side. It may not feel like the wires are in, but tighten the screws on just tug on the wires very gently. If there in, you’ll feel

It's not a silly question at all. Phoenix or Phoenix like contact blocks sometimes stick. As you are turning the screw to the left (looking down from the top), watch the 1/8"- ish (about 1mm) thick

Sorry for this silly question, but with poor eyesight and even with magnifying glass, I cannot figure out how to power up my completed QCX! The green DC connector has 2 screws on the top, loosening
