Robbie, doing this maybe you bend the PCB a bit and a cold solder joint loosed connection? As far as I can see, it's a rev. 1 board ( with two SMPS subboards). Connections between the SMPS boards and

Hudson, no switch on without the 5V SMPS board (see schematics page 1 and QMX QMX_plus Startup ( /g/QRPLabs/wiki/36878 ) section 2). It looks like an overload to Q108 and L101 (broken

I think Han's 'wizard' idea is great, I can turn off the CW functionality and just keep the digital/ssb modes. Perfect!!!

Hi Joe You are correct ""... and how you are holding the key making contact with exposed metal...""" ?and/or touching feed line connectors The issue is rf current on the outside shield of coax feed

Not all, did not have a ssb QSO since 2006. Heck i did not even solder internal mic on my QMX?

I built a midband QMX a couple months ago; it worked fine for a solid handful of QSOs and many hours of use in code practice mode. I was in the process of testing a newly built manual antenna tuner. I

As we all wait for Hans to come up with the complete software for SSB, I wondered if there is a problem making it work at all frequencies due to the way the Si5351 will create the necessary phase

I stop torturing myself and will follow Hans' advice in his post /g/QRPLabs/message/134665. A quick calculation shows me that a basket including a QCX+ 40M kit with enclosure, GPS,

Hi Jim, Maybe the led is bad. ? Can you try powering on the QDX and turning it off before 5 seconds elapsed? ?Then turn it on and try connecting to your computer. 73 Evan AC9TU

I can't find the firmware tweak, but it was nothing major; just a command change or something. I am still getting no communication via USB. The chips all? have their power supplied properly. It's

I sent my QMX off to Jeff (W1NC) and he reported back the following: How lucky we are to have Jeff eagerly taking interest in something causing me frustration. The bad PCM1804 chip was suggested as a

Hi Paul I own both ATU-10 es ATU-100 Out of the box: ATU-10 is QRP, 10 W max Small, light weight and rechargeable batt powered that times out after several minutes Relays are self latching so power

Basic Question Is the ATU 100 a good option to use with a QMX+ Tnx 73 Paul w2eck
