Congrats Barb I really enjoyed the write-up, and was really curious as to the secret ingredient and how you obtained nearly twice the power I did. ?I was also at your banquet table. A fun little

Ray, please read two documents from the QRP Labs Wiki about QMX start up ( /g/QRPLabs/wiki/36878 ) and QMX internal power supply. ( /g/QRPLabs/wiki/36910 ) You will

Bruce, it just says to make sure you don’t have continuity between the center pin of the DC jack and the 90 degree pin header pin closest to it. That pin needs to be soldered to the board but just

Here is a link to a NASA visual guide to SMT soldering: https://workmanship.nasa.gov/lib/insp/2%20books/links/sections/701%20General%20Requirements.html (

When aasembling the power supplies 2.17 step 5 says this; " The pin header pin that is nearest to the +12V pin of the DC power connector is NOT supposed to be connected. If you create a short there,

Yes! I also was there, and it was nice to meet Hans in person (while picking up my QMX+ :) Thank you, Hans. Hello everyone /Claudio

I read your reply with interest as I was thinking something similar. I removed the encoder and cleaned up the solder pads squeaky clean. I saw some flux crud and stuff on the encoder case so cleaned

Jim I just check with DMM from board edge of filet to component lead before I clip the lead. The Plus is the first time I have doubted my soldering skills. regards

Update: I had used the #QMX with a 30W linear amplifier for some time but wanted to go back and try once more to see if it was a one off with the #50W PA... I ran a few QSO with QMX + 50PA supplied

QMX+ build underway after speedy TNT / FedEx delivery to UK. ?The optional case really is meaty and consequently the package weight surprised me. A really nice kit with only a mislaid capacitor and a

Yes, There is a DC (and so zero resistance) connection between every connection of T401 once installed

That is correct, all are connected together at DC and should show ~0 ohm

I wound this torroid and tested the A B and C pairings BEFORE soldering.? All was good A to A, B to B and C to C.? Nothing else had continuity.? Now after soldering in, it appears all are
