Welcome! -- 73, Sardar (AC8L, 4K6SA, VA3DUA).

I went to a local (Florida) park over the weekend with the QMX+ and an MFJ-1979 telescoping whip. The whip is 5m (17 ft) tall - a 1/4-wave on 20m, and on higher bands when retracted appropriately.

Hello, I'm here :-) Not really a design improvement, more a comment to the existing system. The BMS I got from Am... is not really doing it's basic job, or at least what I would have expected. I

Cal, I meant, for your group buy fell free creating a new thread :) -- 73, Sardar (AC8L, 4K6SA, VA3DUA).

It would be helpful for me to see a 2-channel oscilloscope trace of pin1-IC405 with pin1-IC406, and pin7-IC405 with pin7-IC406, to see the 90-degree offset, and any relative voltage offset between

No problem--I'll use the one you created. Not a big deal! 73, Cal (AD8Q)

Thanks Jonas, this problem is solved! 73 de Zrinko Ivan, 9A7AM

I am building the QMX and am winding the L401 torroids. Because I have the 15m-60m kit, the L401 is two torroids. Even though I double-checked my torroid windings on the L401A torroid, after soldering

I think that ship already sailed :) I created new threads, you can go ahead and do the same and we can let current thread die naturally. There are too many messages anyway :) makes it difficult to

Ha--yes...sales, marketing and (non-profit) finance! ;) Or we can do the opposite--keep this thread developmental and you or I could start a new thread. That makes the most sense to me. After I

I have a Low Band and a High Band QDX I would like to sell. Both were tested on 9 volts and a Lipo Battery, 13.3 volts into a dummy load and tested on an antenna for spots. I have only used these as

Cal, Stan, Could you draft your schematics on a piece of a napkin and submit a photo? I am not sure I am visualizing your ideas over the messages? -- 73, Sardar (AC8L, 4K6SA, VA3DUA).

To me - version 1 design is frozen :) Unless catastrophic discoveries are made with new PCB's that less likely :) However, we should continue improvement discussions - that is the sweatiest part of

Hi, Set "Band limits" to "None". P.51 of the operation manual v.26 refers. Regards, Jonas Den m?n 18 nov. 2024 kl 19:21 skrev Zrinko Ivan Vukoja via groups.io <ivan.9a5czi@...>:

My new QMX has a strange tuning problem on 60m only. It is not encoder problem. Tuning has pattern that it follows and it is repeatable. You could see it on this short video:

Quoting myself (again)...and hopefully more accurately asserting: The BMS is not a charger. The Drok regulator AND a suitable power source provide the missing charger functionality, as might the

I completely agree, Cal.? Thank you for the great work you are doing. Stan
