Hans, Yes, thank you. The reason I am asking, for those of you interested, there is someone on QRZ dot com selling an unbuilt 20 because he wants a 40. I have a 20 and am waiting for a 40 but I will

Two more notes: 1) the volume pot for my QCX arrived broken, was not obvious but I checked it with a multimeter before installing and it was infinite resistance across it. Later it fell to two pieces

Hi John Correct. But LOW pass not band pass. To convert from 40m to 20m you would need 2x 180pF NP0 capacitors and 2x 390pF NP0 capacitors. All other components are in the QCX kit already, if you kept

I just went back to the instructions again... Unless I am mistaken everything EXCEPT the BP is in the kit for all bands. The toroids in the BP kit are the same mix for 40 as they are for 20, the diff

John you are correct, but it is more than a change to the LPF after the PA.? in addition there are several band-specific capacitors in the PA circuit itself.? someone with a good stash of parts can

Someone has a QCX-20 for sale, they are waiting?for a QCX-40. After looking at the instructions, as far as I see, the 20 can be made into a 40 easily. Any input from the group?

That is too bad.It looks your flights are doing very well.Maybe needs more altitude? Looking forward to BB05 :) jIM

Hi, Just wanted to say that I have just performed the (resistor) TX instability mod, as detailed on the QRPLabs website and it works. I had an odd symptom where on key down you would sometime gets

Joe, ?That's why when I run across a fb post I like I save it.? That and you can search the group for messages instead of scrolling to look back.?? ?What I've seen in both places is great

Hi folks, I'm selling my assembled 40m QCX transceiver simply because it's not quite as suitable for a QRSS grabber as I hoped. I won't use it as a transceiver so it'll just sit here. It might as well

USB cables are a good choice, IMO. I think the heavier gauge ones will have better shielding. I've seen chassis mount USB connectors are relatively easy to source. I suggest it as an alternative to

Hello Hans, Hope all is well and you enjoyed the holidays with family and friends. Just received my latest batch of kits in the mail... Now I can proceed to build the relay boards that were missing

Very good question, I would suspect so. Just make sure you align USB +ve and -neg to USB power! Data +/- your choice Sent from my iPhone 6

I liked building the kit. Now what was the problem again?

Thanks, those seem like good economical available solutions.? Are all usb cables shielded?

Also printer cables have been readily available in all the various QTHs I go to. 73 Ross Sent from my iPhone 6

Jerry, On all my U1s, U2s, U3s and now my QCX I use USB A for the GPS (and QLG1) and USB B on the Tx. That way I use a printer cable USB A<>USB B as they often hav a ferrite slug and are well

Let's rule out a loose part in audio section.? turn on the builtin signal generator, and gently run your finger across each resistor and capacitor.? don't rule out the simple,? as it could ge a

Alan, I plan to do some rigorous signal tracing tomorrow. So far I've looked at sections but not the entire signal train. That should tell me something interesting. We'll see... I replaced both
