Sorry, I just noticed you are talking about the plus, So it won't be the encoder body causing a short. -- 73, Dan - W2DLC

Hi Michael. When I had a blown PA output transistor, my 12v QMX was drawing a little over 200mA on receive/idle mode. So yours is behaving a little differently at 125mA receive current draw. In my

Great, thank you all!

Hello ! It doesn't work for me from ligthing to USB C, I would have to buy an OTG adapter if I understand correctly [email protected]> escribió:

I received an email from Hans (! Amazing customer service) that the online file was a zip file and that the QMX file was the uncompressed file - so my Mac had already decompressed the file for me.

Thank you, Greg, this helps a lot! Cheers, John VA7JBE

So, I put it on a buck-boost that could give me a better readout than the power bank on amperage draw. At idle, it's drawing 0.125A; transmitting on 20m, it's drawing 1.25A. At this scale, I'm

John, Just saw your 2nd post. I'm not an expert, but what you describe is exactly what happened to me on a first batch QMX+. Along with a few others I believe. I had mine checked and repaired by Jeff

There is no separate rev4 schematic - the rev3 is accurate, only one minor change on the ptt out jack for rev4. All of the terminals of L405a/b should show DC continuity to ground and the other few

I had a chance to open the enclosure and check the continuity on T401 and everything seems to be well connected.? All tests are still as before.? I'm running out of ideas on what could be

or bad coax and or connectors.

Damon, to do some investigation without damage of the BS170 you may feed the PA from a little AA cell in series with a 10 ohm resistor (see this thread (

Hello Stacy, fine to hear about your success! Enjoy this nice radio. And now I guess to know from where ADC_3V3 was coming, from VDD (analog regulated) across the D-S diode of Q111, something

Hello Donat, and RF_IN is connected via L503 to GND. For DC L503 is only a piece of wire with nearly 0 Ohm. So don't worry (see schematics for rev. 2 and higher). 73 Ludwig

Hi Eric, I’ve been having similar thoughts and have been doing FPGA design since 1997. I have an Artix 7 dev board (Digilent Nexys Video) and a Zynq Ultrascale board (Avnet Zuboard) that I’m

Joe, yes, I mean L405a and L405b, which are also referred to as L401a and L401b in the beginning, as you say.

Steve, I am building a QMX+ and doing well with a 1 mm chisel tip on my Hakko. I think that I read something from Hans saying that the board design matches well with a 1 or 2 mm tip. I’ve completed

I'm building this version soon as well, I've been thoroughly going over the manuals and videos. Do you mean L405a and L405b? I've noticed the R4 manual refers these toroids as L401a and L401b in the
