My QMX+ ceased to function last night after working well for a few days after build. It just didn't start up. After probing around I could see the output of IC101 linear reg was only at about 1v when

Thanks for the tip about adding some caps to the encoder outputs....I'll give it a try. The most reliable encoder I have used is one that was advertised as an "optical" encoder...for the price it

Yes, congrats Hans, well deserved. Tuck F4WCV

You could always use toroids.info to get another estimate of the length required. 73 Roger 8P6RX ?Get BlueMail for Android ?

As a follow up, here's the QDX wire post I mentioned in my earlier comment above: /g/QRPLabs/message/87536

This happened to me on my first QDX kit. As W0WLY noted, I always had more than I needed left on the toroid when I used the exact amount stated in the instructions, and ended up not having enough for

Hans, Congrats! As always well done and keep on marching on the right track. Hajo

I understand that they are deleted to maintain a 100MB? limit. There are some emailed photos in the Photo section but searching "nanoVNA" did not seem to find anything. Only 3 which did not seem

Aye, well done Hans.

How are you measuring the power output? I had the same scare with ATU-100 (software modded to work on qrp). It started reporting 1w at 15m and 10m one day, and I thought my QDX has died. But when

Actually more sensitivity is achieved by having less internally generated noise. As others have said if you hear antenna noise then lower RX noise will make no improvement. 73 Alan G4ZFQ

Hi Doug yes - my point is also that this is part of the deal when you work for an employer. Everything they make, from your hard work, is theirs - unless they decide to give you a few crumbs... Or

Hi all Many thanks for your support and for your nominations and comments to ARRL. It is indeed a great honor! I remember back in 2009 being my first time at FDIM and Dayton hamvention, I was there

Congratulations, Hans! Well deserved. A nice package from QRPLabs with QMX+ and all options just arrived, but was immediately hidden by my wife. Now I have an idea what Christmas will bring

Thanks Hans. I think I'm back at number 1 :)

Digital mode uses a wideband filter to receive the whole SSB receive bandwidth, about 200Hz to about 3200 Hz. In CW mode you select your filter.? You can select it to be "off", which then reverts to
