The use of a low-melting point alloy such as ChipQuik will be a tremendous help in getting the solder to flow without excessive heat. I also use a #15 scalpel blade to cut the individual leads right

Hi Randy, Are you starting transmission by pressing the right encoder or the left (select) button?? The QMX works the same as the QCX series in that the left button repeats but pressing the encoder

It would be wise to connect the dongle and set (and confirm) its voltage prior to connecting the radio than to do the reverse and possibly subject the radio to voltage gyrations while the dongle

Has anyone tried to move the QDX-M to 6-meters? What changes had to be made to the firmware and the LPF? I know the performance may not be perfect but I'm looking to experiment with it. Any help would

I know it may not seem like an RFI problem, but it still feels like an RFI problem from the given symptoms. One of the problems that can happen is that the RF doesn’t make it out of the radio, but

Thank you Hans, quick

Hi Billy QMX is USB-2. Just uses a USB-C connector to carry it. So a USB-2 and adapters is fine. 73 Hans G0UPL http://qrp-labs.com https://buymeacoffee.com/g0upl

Here we found it easier to achieve precise alignment of the SMPS boards if the spacer nuts are NOT drilled out. The reason is that drilling them out, or shoving a soldering iron through them, either

Hans says it’s best to do it as he shows in the video to keep the boards properly oriented. Looked really easy to do the way he demonstrated. It’s an ongoing process of finding the best solutions

Does the QMX depend on having full USB3 support at the PC level, or can an USB Type C adapter be used? I am looking at ordering a QMX, but do not have USB3 available. I do have a multiple input USB3

So to clarify - The manual at Rev H currently says to burn or drill out the center of the spacer nuts on the power board - That is no longer recommended according to the video?

Perhaps this has already been reported, but in the Message menu, setting Interval to 7 seconds, and repeat to 3 only sends the message once (Message 1, if it matters). 73, Randy, KS4L

That’s my plan too. Got the QMX but upconverter is on the slow boat from China… PD seems risky. Another post about the PD negotiation and starting on 5V then a fast increase kills the QMX. Should

Correct.

jlloydham, Could it be from the power supply?? Maybe a local RF source in the shack?? Long shots, as the sound system is all digital inside the processor. 73 Evan AC9TU

OT sucessfully build your interface for my ic706 the only problem i have is adjusting. I have mo sweet point where ptt gets triggered and alc is zero for ft8. Any idea ? Mny tnx/ /OT

I’m happy to do that for you. ?Only pay postage and parts plus whatever donation you want. ?I’ve done a bunch of these. send it to me at Jeff Moore 464 Route 28 Harwich Port, Ma 02646
