I went this way and never have looked back: YIHUA Hot Air Rework Station a.co and YIHUA Desoldering Station a.co A few more bucks, but I have used them heavily ever since. I just use a small 12v fan

Dear Stan, Thank you for your interest, I have already tried what you wrote before, but I checked it again in order and the result is the same, no new ports (COM & LPT) appear in the "device manager"

Greg, a better solution would be to add a FET switch to turn on your relay - the gate of a FET is what the output of QMX was designed for, not to directly drive a relay. A simple FET switch and a

Tayfun, Often Windows will not make a sound at all when you plug in the QMX+ correctly, because it uses the same USB virtual serial port we use on other devices, and it already has the driver

Good evening from chilly Southwest Florida I've run into an issue with a relay I wired into an adjustable attenuator board. The PTT signals coming from both my QMX HB Rev2 and my QDX LB rev 5 aren't

Hello Greg:? based on your experience with it and reviews I've read on Amazon, I'm going to order the WEP 882D.? Just $60.00 -- amazing, for so much flexibility!? The fact that you built so many

Hello, I just built a QMX+, the controls on the device work, but I couldn't test it fully because I don't have an HF antenna in my workshop. When I wanted to test it by connecting it to my computer, I

Mine did that recently too.Just shutdown everything and reconnected PD bank and trigger cable, USB cable, dummy load etc. Have no idea why.Just did it once. GREG Yahoo Mail: Search, Organize, Conquer

I have tried the dummy load with no change in symptoms. Mike, your FT8 plot at least gave me a hint of how to 'see' the tone, HIHI.? I had to install WSJT-X on my little Raspberry and set it up (

From the pic, it appears to be a QMX+. - Bruce K1FFX

I've seem this once and am also puzzled.? However I have noticed that my QMX is susceptible to ESD and if it gets zapped it does weird things.? (when my clothes clash ESDwise with the material in my

What device? The message seems to indicate a problem with, or around, the SI5351 73 Alan G4ZFQ

Hanz, I don’t have a QMX+ V1, but I’m not convinced that you have interpreted the pinout of JP104 correctly. ?I think pin 6 should be ground, not pin 2, using the numbers you have added in the

When the device is turned on, it shuts down after this error message. What could be the reason for this error?

Well rats. Honestly I'm out of ideas. I can't imagine why the Mac thought the Q was consuming too much power, as the USB on the QMX only uses the two data lines. No traces from the USB to anything

Excellent! Tuning off Shapped tx did it! Stan, thank you so much for your help. Best 73, Bob

Sorry Nick i forgot to mention the plus.

1. Make sure that TxID is turned off.? Its timing is incompatible with QMX current tone detection, and QMX will drop tx in the pause between the TxID and normal modem signal (happens in many fldigi

I’m trying to use Fldigi RTTY and seeing the PTT dropping at the very beginning of transmitting text. watching QMX output on my scope I see initial RF signal for less than a second and then output
