bonsoir Hans, j"ai le n°1036 pour un qcx 40m je vois que c"est bloqué au n°695 j'aurai du recevoir mon qcx mi octobre que veulent dire 'autres groupes' qui portent le n°1224 est-ce que cela veut

Hi Peter, I ended up bending that same flap on mine. I did it because it hit the top of the toroid when I tried to sandwich the display down. Anyway glad you figured it out. Joel N6ALT

I tracked all of this down to a bad BNC connector, I believe the chassis mount connector I have is 75ohm. The center pins are different sizes. Have it running great now on both bands :) -- Ryan

Thanks Vin for your suggestion. I think I found the root cause in the meantime: I tried lower values for the pot, and also Arv's suggestion to replace the pot with a 2K2 resistor to ground (this

You have hit a bug.? Set PTT Delay to zero and then the tune mode will work.

Hans, Oops. It sounds like I didn't read "ALL" of the manual. I thought the instructions were to scroll the 2-line display. No worries. The clock works wonderfully with two lines. I've had one

Sorry Roger! ? I have built several QRP Labs kits and always I diode protect for reverse voltage. However, that over voltage application is a bad boy! Yep, I did it once as well!! Cheers! Dave

Julian, On this ( http://blog.zakkemble.co.uk/avrdudess-a-gui-for-avrdude/ ) page you'll find this instruction:? <quote> AVRDUDE requires?LibUSB LibUSB should really be installed the normal way as

Chears Chaps, I'll investigate further over this week. Im sure its something smple, just dont know what yet.

Hi Steve and Hans, tonight I wired my 49er amp section to the QCX's volume control just before the audio amp section and Steve I now have the same experience as you, a lively receiver!!! It would

I just noticed that when I press the right button on the U3S it does not key the transmit like 3.10a did.do I have something set wrong? Vernon

Thanks Hans & Dave. ?Once the kit finally gets here, I can easily build it for 20 meters rather than the 40 meters I originally ordered. Good group here, very quick response to questions. Jim -

I'd say it was a driver problem too. Google Zadig and give that ago to load the drivers for the USBasp or USBtiny if those are the programmers you are using. I've used them in windows 10 and XP with

Hi PJH. I am indeed a newbie and have been one for 50 years. HI HI. That's why I'm glad to have this facility to get opinions from those in the know. Thanks, Marc

Hey guys, When I enter “Peak BPF” the displayed amplitude is varying somewhat. Several bars. I do my best to come up with the max where the factor on the top right is 8 or 9. The blades of the C1

Jim, The microprocessor is pre-programmed for every usable band. You just set it for the band of your choice in “step 1” of the alignment process. Dave W7AQK Sent: Monday, October 30, 2017

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
