I am using my new QMX+ with the HardRock-50+ (HR-50+) amplifier with its integrated ATU. The ATU requires a bit of RF energy to trigger the tuning procedure.? So, one pushes the Tune button on the

it worked but now a new bug where I don't know where to look. QMX+ is selected in WSJTX input and the PC and decoding is ok but no transmit and when I try to transmit I get? a rig control

Hi Roger, Looks like a nice setup. I am wondering what tuner you are using in the photo? 73, Ken K9ZI

Okay I think it was my antenna, I haven't even weirder problem now. As soon as I start transmitting after around 3 seconds, the whole qmx just turns off [email protected]> wrote:

Chris, first half of tests was done with smpsu boards removed from main board. Second part, pressing the power switch, was re-assembled.

My antenna system is rather compromised at the moment, so I'm not sure whether I will be heard, but I will try! Thanks for organizing these, Ed. Greg, N1TR

I finally had enough with the ESD upsets when touching the knobs.? On the last occasion I lost my memory settings due to to a reset.? ?Today I worked out a solution.? I cut a piece of copper foil

Dan, never ever run a QMX with SMPS boards if the off line tests are not ok!!! It looks like a short at VDD (or a faulty PCB#2). Please remove all subboards and check resistance at the mainboard

Are your tests with the power supply boards unplugged?? Not connected to anything?? If so then quite a lot of both boards seem to be bad.? They are both shorted to ground enough that the current

I am interested and tried to send another email. The first one I sent bounced. Not sure if it is on your end or mine. I did get your email and attempted to reply.

OK folks, did some measurements a few minutes ago and have interesting results. But first, to answer a couple questions: The power supply is not current limited, and the voltage is a pretty solid

There is plenty of 10m activity on FT8 right now, at least where I am.? Check your audio card settings. Stan KC7XE

Would any of you happen to know what these vertical lines are on the waterfall? I'm trying to do a Winlink P2P connection with a friend 30 miles away via NVIS and noticed these lines would sometimes

Is 10m active today? Because I get around 3w out but I hear nothing on ft8

Hi Stan Thanks for the pointers. I got hold of a current-limiting PSU, and did the tests suggested in the wiki here: /g/QRPLabs/wiki/37128 on PCB#1: step 2, I got Vcc = 4.1v

Roger great to hear its working! Thanks for sharing. Your picture got me curious - what antenna are you using with the tuner and Elecraft balun? 73 KD2WQI [email protected]> wrote:

About the best option for sharing physical COMM ports is using TCP/IP. WSJT-X has a radio option for it, and most logging programs will also connect to it. There is also a hardware option - create

Got your order, Glen. Also sent you a private message John. My bubble mailers didn't show up Saturday like they were supposed to, Amazon is telling me they should show up by Tuesday, so it looks like

I try to repurpose that stuff all the time. Did it have that ribbon wire in it? Thats the wire with laquered ribbon wrapped on some kind of poly thread that's? impossible to solder; found in most ear

Either way would have been fine. Releasing SSB firmware for 80m only, no CESS, limited menu, no support for CW or digital modes, no calibration step would have shut down the "This EER SSB Stuff Can't
