John:? There was a thread on here about recent change to the LED behavior.? There is info in the release notes about it as well. /g/QRPLabs/topic/96336679 Tim Raymer 73 de N0UI

In the assembly manual of the the latest qdx m I noticed in section 2.9? the table describes L2. Shouldn't it be L4 as shown in the diagram?? My PCB is rev5 M Am I missing something? Wes Va3RYV --

John, Yes, this is the new normal with the slowly pulsating LED. The Night mode is totally separate and is also set in the QDX configuration by the user. 73, Cliff, AE5ZA

I updated another QDX to 1.08a, and now the RED LED fades in/Out on Transmit. Wondering if this is the new behavior of the LED. As far as I know, I'm NOT in Night mode. - John

Check all the connections at the volume control. That’s a tricky install as you have to bend the tabs. Check the control itself with a VOM DVM. There’s 2 resistors above the display, make sure you

Gary - no audio from the BPF p.pippi, thanks for that info.? Reset did nothing to help.

John, That, the slow fading up and down may still be part of firmware 1.08a. There's also a 'night mode' that dims the LED's brightness; I think in that mode QDX's LED does not fade up/down but

I am repairing a QDX -- One of the final BS170's (Q10) was blown. It appears to be working now, with the exception of the RED LED. When in TX, it slowly fades ON/OFF, at about 1 second intervals

Hi Mark, Try resetting the QCX. You find the reset in the ?other“ menu point. Use a 50Ohm Dummy load and go through the alignment menu points again. I had a similar problem. Make sure that when

When you adjust the BPF do you hear a tone?

Thanks again for the help. Steps taken: * Confirmed connectivity from center of BNC through L1, L2 and L3 using DVM * Resoldered 1 & 2 taps for T1, and confirmed connectivity using DVM * Went into

Check each connection on the volume control. That can be a problem also. Did you have continuity from center pin on the BNC through L3?

Gary, no audio at all. Ron, I will re-check again the large windings on T1 to confirm connectivity.

Hello Hans Abi When I entered the 2200m or 630m or 4m values (not at the same time) transmit becomes disabled It was very late and I didn't push to solve it. tomorrow I'm returning to Istanbul, there

Hi, so, to summarize what it was said: 1. power the QDX connected via an USB cable to the PC. 2. On the PC run a terminal program, preferably Putty. 3. Connect to the QDX by choosing the QDX's COM

Jim. Note section 8.6 in the operating manual. Setting system time corrects clock drift. "If a GPS unit is available, then you can use the GPS calibration tools to calibrate this value (see below)."

I am using this at our radio club station, as well as my own FT8 setup and several of our POTA ops use it ... we are all VERY satisfied with the performance ... it is WELL WORTH the small fee ...

Like others have said, replacement is the best option. I'd suggest a chassis mount BNC connector attached to the end of the case and a couple of short pigtail leads to the PCB. These should be
