All measurements of power from a Daiwa meter (lowest range is 15W) via dummy load (very brief tests on antenna almost identical). 20M - 10M power out shows as 2.3-2.5W. I don't, however, think this is

unfortunately what I didn't want to happen happened, in unsoldering Q103 it broke, and also the green paint of the board came off. I do not know what to do. I just hope Hans can send me another

OK, thank you for the answer to that. But holding both ADC lines (3V3 and 5V) at 3V3 would mean the LIN_REG_EN signal to go low I assume. So it would switch off the on-board 78M33 and thus prevent

I would check the voltage on the intersection of Q511 and L509

Hi Jerry, Can you post a photo of the underside of the board? -- Colin - K6JTH http://tangokeys.com

Hans, I believe there was some mistaken identity between R510 and C510.? R510 is right next to C509. But that said, Karl still has a missing C509.

Karl, C509 is 0.1uF per page 18 of the assembly manual. It's also listed that way on the schematic. -mike/w1mt <karlshumaker@...> wrote:

Thanks John for the tips. It'll be checked after removal. I still doubt the 5 V supply was ever high, but you're right, I don't know that for sure. Reasons I think it's unlikely is that if there was

Hans, I just finished my QMX build, and all is OK after replacing a cracked C526, either by too much heat or careless wire cutters.? But all is good after replacement. I guess lack of AGC means

Hi all, good news - my QMX is up now and we have clean signals on 80/60/40. Only on 30/20 is something faulty. First I thought the LPF is on bad condition but measurements (DMM in diode-test-mode)

Thanks Rick and Paul. I also noticed that Q103 is very close to Q104. I think I'll have to desolder Q103 to move it around a bit. I'll let you know. thanks for your advice.73 Giuseppe iu8eun

Hans! What should be the farads of C509? No matter what C510 is since Rick's radio receives an it is rhe same as mine. But I need to replace the missing C509 and have no idea what the value should

Karl, I checked that resistance during construction and after repairs. Very high resistance both times. -- 73, Dan? NM3A

Hi all As is normal, none of the MLCC in the QMX have any markings are all. So where are any of you seeing "103" on a capacitor which is supposed to be "225" (2.2uF)... I'm feeling lost... 73 Hans

Mike, Yes, it's connected by a trace. Walt - KK4DF

Steve, Thanks so much.? I completed my QMX build today, went through all the preliminary power board checks, loaded the firmware, and began testing.? No power out on any band!? Your inspection #3

No marking, it's just an unmarked tan SMD.? The component next to C509 is resistor R510. C510 is closer to the USB port, and is also a tan, unmarked capacitor.

Rick! What is the marking on your C509?!

Hang on, I was looking at R510, which is right next to C509. Maybe that's what you saw too, Karl.

Hello all, I just finished building my first QRP Labs project, a QCX-Mini for 10 meters.? I am new to this group and this is my first post.? Is this the appropriate group to discuss the QCX-Mini??
