It looks like a Phoenix Transmatch? https://qrper.com/2022/03/richard-recommends-the-qrp-pocket-transmatch/

Just use the Tune SWR feature.? It (by default) uses 1/4 power, which is low enough that even very high SWR won't cause damage.? And SWR protection is automatically disabled in this mode.

newest go-box with QMX, Talentcell powerbank, noname speaker and tiny paddle by N6ARA, completly fits in a beauty case by UGREEN.... only a portable 8m pole (70cm packed) and some coax as extra

Ludwig Thanks for your coment, with sub-boards removed, I have 6.6k ohm gnd to Vcc and 2.3k ohm gnd to Vdd. Do you think this indicates something broken on the main board? Dan

Perhaps, ill-advisedly, I turn off my SWR protection long enough to tune, then turn it back on. -- 73 Michael N6QP Up in Thin R

Hi all, while I am eagerly awaiting the stable release of the SSB update (not brave enough for the beta) I am trying to figure the microphone situation. I am absolute newbie both in amateur radio and

we can just see Ed 14.058.5, on the 7300 scope and copy is 55n from OR. ?can't hear any others.

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
