Hello Mike I think it's a nice idea but I don't know how to accomplish that in practice. What you're talking about is kind of the old PC "DLL" concept. Native code that has to be in a relocatable

I made the wire a bit longer than needed, maybe an inch so I had a bit to work with, then after identifying and aligning the pairs, inserted one pair of wires at a time, kind of "rolling" the toroid

With that wire broken, you won't be getting your main 3.3V supply rail, so lots of things won't work. One wire from that inductor should be soldered to the pad right below the notch in the inductor

Btw, the cli program Screen works well in xterm as a serial comm utility to interface the QMX.

That worked! Thank you, I was able to get into the terminal, look at all the settings, turn off the rig with the Vol button after selecting exit in the terminal. Thanks!

Thanks for the offer. Yes, unfortunately, I have soldered the male 4 pin to the board. ?I’m trying to think of a way to salvage this without desoldering (makes a mess). ?But, I may not have an

Hi Chris, What computer and operating system are you using? Have you exchanged USB cables? It may take another try with 1.00_27. I have had to delete old files and re -download once. Thanks, George

Joel, I have a QDX-M here I plan to build for 160m over the winter. I had came up with values for the LPF in Elsie and another online calculator, and then Hans came out with the QMX+. People seem to

Ok. Thanks for the affirmation that the flux isn’t the issue ?while using the jewelers loop, I found this. Mr. Ludwig, could this cause the overload condition? Somehow the wire got pinched or hit

I think I have a few 2x4 female pin header sockets in my parts bin. Let me know if you want me to send you one in the mail. Have you already soldered the male pin header to the mainboard? 72 de va3rr

Hello, It seems I did the same thing as Tim and inverted the male/female plugs. I’ve read the mail here, and understand that the two outside plugs are just as happy left inverted. So, now it’s all

Phase of the reflected power is also a crucial factor, not simply its magnitude. 73, Don N2VGU

Not a short, a distant possibility would be excessive leakage in a very high-impedance circuit.? Not an issue with these kits. You need a solder splash or icicle, or metallic whisker of some kind to

Both the LPFs and non matched load reflect power back to the BS170s.? This chart shows the effect of the LPFs:

I think settings are saved when you /turn the radio off/, not remove power! Press the left (volume) encoder until the display has read "shut down", and you'll probably be good! 73, Paul -- AI7JR --

I connected for the first time to my QMX (high band) via linux and putty (found the usb device via dmesg), connected and looked around a bit, added some preset frequencies, navigated to exit and

Very well put together beginnings of a slide deck. Trying to come up with a fixed SWR value is difficult; Partially because like another poster said, impedance is a complex relationship and it is much

Hi Joel QMX+'s 6m LPFs and BPF worked with no problem with QDX-M (8m was bonus) 160-80-40 should work even try 2200, 630 :) 73 DE muhsin TA1MHS

I'm doing a deep dive into cause of BS-170 failures. Currently I have finished evaluating peak BS-170 Drain to Source voltage and am in the middle of power dissipation for various SWRs. * On 160m and

I’ve had a hankering for a monoband QDX or three. With 160 meter support in the QMX+ is there an (experimental) path forward for 160, 80, or 40 meter monoband builds perhaps by duplicating the
