Kudos Hans. Fantastic systems life cycle engineering.More amazing every day.? 73 GREG KI4NVX?

Hello George Sure, I can do that... generally the wire diameter is really non-critical. Almost anything goes. Some of the LPF toroids you'd struggle with thicker than #28 (0.33mm) as the turns

Hi Hans, #28 being used overall, will it be possible for you to sell an additional length coil in the component section of the site for us "worry that we will? run out" types? TNX and have a good

Hello all I have released firmware 1_00_027 at http://qrp-labs.com/qmx - the changes are minor and there is no change in operator functionality so there is no new operating manual required for it,

Hi all To let you know, from now onward all QMX+ kits will ship with PCB Rev 2. That also includes most assembled QMX+ on the waiting list. The changes for Rev 2 are listed below. The main change is

Hello, has anyone yet integrated a voltage buck converter (from 12.8V to 6V) into the body or a case around the QLG2 GPS unit? I am thinking of installing a small PCB like this between the main QLG2

Hi Ludwig, of course, sorry for my mistake. I plan to follow the signal with an oscilloscope from T507 to ADC_FWD and ADC_REV (they had 0 V on TX). 73 Bernd

I had a similar experience with my QMX+, could find nothing wrong except I had some noise on a wall wart which I swapped out and initially thought was the cause but still experienced the same

A friend just upgraded my QMX with his Mac laptop. He brought his laptop to breakfast and it wouldn’t connect. He took it home and used his older Mac Air and it updated easily. He can’t explain

Thanks Hans... Great to be building another of your kits.. Many many years since my first kit when QrpLabs first started......trust you are keeping well Phil G4JVF

Hi Phil, all PCM1804 problems are still a mystery. There is no problem with the chips, we use the same chips in the QDX which doesn't have any problems. It's a complex problem and I don't have an

There may be some misunderstanding. I saw a message here yesterday that said on power-up, the QMX showed up as a disk drive on the PC, but it did not begin downloading firmware. This is a

I spent ages trying to get mine going too. Couple of tips. 1. Can you see QMX on file explorer? 2. Can you hear pop in headphones when you turn it on? 3. If Yes. Go yo QRP Labs website, drag the

Would this suggest a batch/manufacture problem on the original chips? Thanks for the info Jeff.... might need you to fly over to the UK when/if mine fails :) Phil G4JVF

Scott, Did you try power cycling the QDX? ?Once the QDX is connected it will not reconnect if you unplug the USB port without turing it off and then on again. 73 Evan AC9TU

A new chat has been created: . I made a previous mistake and used up all the .33mm wire. Can I use 28AWG (.40mm) for this component? *By:* James <jmrobertsjmr@...> View/Join This Chat (

Epilogue I received a new pair of SMPS boards today and installed them. The QMX is as good as new! Fortunately, nothing else was damaged. 73, Mike KK7ER
