George, it'd be a bit hard, as you're not giving much information I think. The more the better. Based on what you wrote in your first post, I gave a long answer, but you did not mention if you have

Exactly, and I think the instructions warn of this, you have to set the volume at a point for the reading to be around the middle so that your adjustments will make sense, and you may in fact vary it

Not able to go to the the built in DVM. Nothing showing on the display. Was hoping someone could suggest an area to look at. No response from Hans. 72 George/W2BPI In a message dated 11/14/2017

I found that when doing the IQ adjustments with the 3 potmeters you have to open up the volume control in order to get any reading at all. So if you have turned down your volume completely that might

Hello Hans, Wednesday, November 15, 2017 No worries, not life changing, thanks for the (ultra) fast reply Hans! :) -- 2E0ILY Best regards, Chris

Hi Chris Still pending :-/ 73 Hans G0UPL http://qrp-labs.com

Chris Wilson 15 November 2017 I think this is a known issue, I am using 12a firmware, is this supposed to be addressed with this firmware or is it pending? Thanks Hans! -- 2E0ILY Best

Hi Vernon The LPF would not cause drift. Drift is related only to the 27MHz Si5351A reference oscillator. 20m is the first transmission after your calibration pause. Things I would try myself: 1)

Hi Klaus, Sorry to hear you're having problems with your QCX too. I have been tracing circuits to see if there is possibly something else wrong beside T1. I plan to inject a small signal right into

And for those interested, this article is available on The Internet Archive as a separate article. While it's not an 'ideal' device it does have many

Once I installed WinAvr, AvrDude installed fine. AvrDudess gave me the missing libusb0.dll error on the first try, but on a second shot, it installed just fine. AvrDudess talks to the Arduino and

Hello Bob and Hans, I was very surprised and ashamed to say my WSPR test transmission result as before. Your QCX(3W) and 6m long Vertical works great job I think. Sorry but I did not modify my QCX to

BINGO! All better. Thank you Barry and now I'll be able to update once my QCX gets here and I get it built. Jim - W0EB

Install WinAvr. Launch it, that will install the missing .dll thingy and AvrDude / Dudess will be happy. I too sun windows 10 Pro. barry

George, I'm a total incompetent when it comes to electronics... but it seems like clearly something is very wrong: a short somewhere, or an open circuit, or one or more damaged components. If you

It can be done. However, you are going to have an impedance bump at the connection between the two. This may or may not make a difference. It certainly un-neatens the job. If you are short only a few

Hello I have had a problem winding the transformer T1 and now find I am short of wire. I do have some wire of a slightly thicker gauge. Would this have much effect on the characteristics of the

no load on the 3.3 volt rail, and it didn't occur to me to try the scope. I'll rig up a load resistor and hang the scope of it. -Justin N2TOH
