I have been trying to get somewhere troubleshooting why my 12v QMX will not boot or show up as a USB device. I have checked the power supply boards, which seem to be working, and have followed all the

All, The other week my U3s stopped working, it coincided with a nearby thunderstorm. I had been tx'ing wspr and qrss at the time, noticed spots had ceased, checked U3s and just a blank blue screen,

Wayne, I'm not a Windows guy, but in Linux sometimes the QDX soundcard can get assigned to the wrong device, such as HDMI or something of the sort and it has to be corrected to get it to work with

Ok. Sorry Wayne. I am out of ideas, Windows is not my scene. Maybe someone else can help. Roger ?Get BlueMail for Android ?

Maybe. I did check them all and they all ohmed out correctly. So, during my troubleshooting, I came across this error again: I'm still thinking this is either a sound card problem (I know there isn't

I cannot recommend the ATU-100 Chinese look alike after having built one. If left in the automatic mode, it goes through a re-tuning cycle EVERY time you go into transmit mode even if you do not

I posted a couple days ago about a super simple albeit kludged option involving some diodes to limit the voltage on the headphone cable.? Might be worth trying.

Come on Bruce, get it right.? LOL..? I took a jumper from the RF connector shell and touched the ground connection on the power connector and it fired up.? I normally fill the holes up on the power

Ok. So no output at the dummy load. I would now start working backwards from the BNC socket centre pin,through the LPFs to the PA, checking for continuity. QDX turned off, ok! I suspect you have a

Correct, pulsing. I didn't hold it the keys down until you suggested that, lol. OK, my dummy load does have a power meter attached. It's analog and the needles do not move at all. I'm not sure about

If you review the as designed turns and inductance and compare with measured or even calculated inductance, you'll see why L513 turns need to be tight together or add one turn and spread them. I mod

Did anyone already find a solution for the problem with FT8CN? Sometimes the first transmission works, often even not the first one. The QMX just shows two Dots, as a sign of not enough signal and no

By 'a single slow flash', I am assuming you mean 'pulsing', while you hold down 't'. Good. Does your dummy load have a power meter attached, or can you measure the voltage across the dummy load

Yeah...that Digirig is fantastic. I have one for my G90.

I get a momentary single fast flash on the LED and PTT Signal in putty shows on, then off when I run a PTT test. I get a single slow flash on the LED when I run a PTT and Transmit test and the PTT

Hi All, First time post in this group for me though I have been lurking for some time ? Having recently discovered QRP Labs and being immediately impressed with the engineering within the QMX

Willie - yeah its kinda weird. Even if I go to clock settings and force an update it can sometimes not sync, even trying different servers. I assumed a wi-fi lag Jim - JTsync sounds cool. Except for

Why? Nobody will know the difference, you are chasing unicorns, leave it as it is and use it.
