I will be using some of these for my 30m QCX (when I get time to build it) https://thepihut.com/products/stackable-header-8-pin-extended I think they are intended for making Arduino shields. I've

Hi all I obtained a dimensions drawing of the rotary encoder from my supplier and I have put it on the builders' gallery page see http://qrp-labs.com/qcx/qcxgallery.html 73 Hans

After some digging I found one in the junk box, so I'm fine, thanks anyways (: 73 de sa2kng

Hi Justin, the I and Q signals are outputs, if you really mean the additional CLK1 LO input signal, yes I used the spare connector holes next to the 'TX input/Rx Mute' pin to fit more connector pins

Hi Mike Yes, you can scroll the information on line 1 and line 2 also. For example if you wanted to show GPS Latitude, Longitude then Grid square on row 2, edit Line 2 parameter to contain for

Ken, Ah very good and thank you for such a quick reply! another question if I may, do you have a suggested pin on the connector strip for injecting the I and Q signals? I'm entertaining a notion of a

Marc, I'm probably not one that is much in the know but like you have been a newbie for a lot of years. Love building kits and other bit and pieces. I see that you answered your own question.?

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 -
