Hi all, For those interested in delivery times: 26th July ordered QCX20. 27th July despatched from QRP Labs. 31st July despatched from Turkey. ? 9th Aug received UK International Processing Centre

So it's local. Will now begin troubleshooting the signal path. Thanks

It has been a week since I've received any emails from the QRPLabs group. Don't see any changes in spam filter or anything. Is anyone else experiencing this problem?

I'm about to start construction of the VFO/SigGen HF Sinewave Set, of which one component is the VFO/SigGen kit.? The PCB is marked QCU Rev 4.? The URL to download its assembly manual includes QCU

Correct Al, from the schematic the quick & dirty way to discount the windings in the LPF chain in one step for others:- test prod on BNC Ant socket centre, and other prod to make sure you have

A sidebar comment.? It's one thing to check continuity of windings by making contact with the exposed ends of the windings as they lay exposed on the circuit board after soldering. It's an entirely

What about this: https://qrp-labs.com/images/lpfkit/gqrplpf.pdf ? 73 -dst-

An interesting observation about it being just the sidetone. I'll have to try it into a dummy load and listen on another rig. And if it never goes wrong that will point to RF. -- 73 Richard G4TGJ

Hi Seth I'm running my 40m QCX off 8V with a solid 1W output and no problems.? I fired it up like that first time, partly to reduce the chances of damage if I'd made a build error, now because I'm

Hi Ken, Thanks for the information on your VHF mods. I was going to ask if you measured power out of the BS170 but I believe you answered that here. I assume 20 mW is with 9V. There are RF power

Check you are not getting RF in. I took my QCX to the top of a local hill and using my Palm Paddle had some problems, including? sending a "/" - dah-dit-dit-dah-dit Really mangled it! I changed rig

I seem to recall reading that the QRP Labs LPF Kits have a typical insertion loss of something less than 1dB, but I can't seem to find that information anywhere in? the current documentation or

Iambic B is supposed to be the self-completing version of keying, so I don’t see this as a problem. Iambic A will NOT add the final dot or dash unless you physically hold the key long enough or

I am not near my QCX actually but I think it was double click left , set the RIT, confirm left, exit right. Martin

Hi Richard I have same problem in iambic A with my QCX/20M, C looks like a M, Q looks like a O; keyer miss some caracteres and if I increase speed the problem will be worst, I am working in iambic

Hi Ken, Not better, different. ?Thinking about easy access to VHF PA's rather than starting from scratch. Strip the driver & PA PCB's from a High Band Pye W15 Westminster PMR

There seems to be a priority issue, although I have noticed that it is with the sidetone. The character will show correctly on the reader if you “stand your ground” in keying the character.

Has anyone noticed any issues with the built-in keyer? When I first used it it often dropped the final dit of a character. For example, often C would be sent as K. Changing it to Iambic B seemed to

It doesn't work like that for me. When I exit with the right button it goes back to the original receive frequency. When I double click the left button it shows an offset of 0. I'll have to work out

I think its not a RIT as we are used to. You set the offset and the exit with the right button. The offset remains and you can transmit. Martin DK3UW
