From previous posts I take it that Mark is a newbie at building. There is also the possibility that when soldered onto the pcb that solder wicked up into the connector block and soldered the pieces

Hi Jim The programming of the firmware does not have to be changed per band. 73 Hans G0UPL http://qrp-labs.com

Hi Daniel I don't know what thread the nut is. It is supposed to come with a nut. Would you like me to post you one? 73 Hans G0UPL http://qrp-labs.com

Thanks Shirley, I have that pretty much figured out but my last question was:? does the programming in the microprocessor have to be changed on a per-band basis?? If it does then that would make it

Sounds quite strange, if the MCU does not initialize the LCD, it should show one row of squares and the other row clear. Starting it without the MCU should give you this and adjusting the contrast

One part missing from a yota QCX, the nut for the encoder. Is it supposed to come with one ? Seems to be the same thread as the potentiometer, but I don't know what thread/dimension it's supposed to

Julian, What programmer? With a USBasp I had a message something like that with another software. This required the ISP speed to be set to "Auto" in Khazama, maybe something similar in other

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 the

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 R5

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 G0UPL http://qrp-labs.com
