QMX+ Info Required

Robert Dale Member Profile All Messages By This Member #145448 Can one of the QMX+ builders tell me: 1) the dimensions of the main PCB 2) the dimensions of the front panel PCB ? After building and using the terrific little QMX, I am considering building the QMX+ but using my own enclosure. ? Thanks! 73 Robert VE7ZN
Jerry Gaffke All Messages By This Member #145457 Robert, ? The approximate QMX+ dimensions as I measure them are as follows: ? Main board is 128.8mm long by 100.0mm wide Main board needs at least 3mm of clearance from the bottom of the enclosure The rear panel of the enclosure is flush with the back edge of the main board Front panel circuit board is 95.0mm wide by 49.4mm high, centered across the 100mm width of the main board The bottom of the front panel circuit board is 2.5mm below the bottom of the main board The inside surface of the front panel of the enclosure is 12.5mm from the back (far side, nearest main board) of the front panel circuit board. The connectors between the front of the main board and the front panel circuit board nearest surface enforce a roughly 2mm air gap there, the exact value depends on how the phone and mic "paddle board" gets soldered in place. The enclosure Hans provides is quite roomy, should accomodate any additional equipment I might want to add. Fabricating something similar that looks good would be a project. ? Jerry, KE7ER ?

Ahand59 All Messages By This Member #145458 main PCB is 10cm X 12.8cm. The tallest component on my pcb is 1.8cm tall (GPS) ? Regarding the front panel board, I'm guessing you want just the board and components, NOT the actual front panel itself or the 2 larger knobs? 9.4cm X 4.9cm (at the widest). This board is around 3.1cm thick. You have the 2 jacks that stick out on one side and the 2032 battery that sticks out on the opposite side.? ? Personally, I purchased the case. I prefer a metal case surrounding something with a bunch of inductors like this and am quite happy with the case.? good luck... Ahand59

Brian Hathaway All Messages By This Member #145460 In addition to the excellent answers you've already gotten, remember that there are full engineering drawings of the official enclosure on the QMX+ page near the bottom you can use as a guide.
Robert Dale Member Profile All Messages By This Member #145474 Yes, I did. Those drawings are for the enclosure/front panel. I'm ONLY interested in the actual PCB dimensions, per my initial query. 73, Robert VE7ZN
Robert Dale Member Profile All Messages By This Member #145475 Yes, I'm aware. I'm not interested in the enclosure, as mentioned - I'm ONLY interested in the PCBs... but thanks for your input. ? 73, Robert VE7ZN
Robert Dale Member Profile All Messages By This Member #145476 Thank you. Exactly what I was looking for. ? 73, Robert VE7ZN
Robert Dale Member Profile All Messages By This Member #145477 Thanks, that is what I was looking for... ? 73, Robert VE7ZN
Robert Dale Member Profile All Messages By This Member #145478 For those wondering why I might consider a different enclosure... ? I'm thinking about designing a "hand-held" enclosure with integral "legs" to prop it up on a table/desk, if desired. The enclosure would (obviously) have a front panel with the display and all controls and the main PCB mounted behind it ("sandwich" style) on the same plane as opposed to perpendicular to the front panel board. The "rear panel" ports would then be on the right-side of the thinner enclosure.? ? I would include an internal, rechargeable Li-Ion battery with voltage protection, and a powered speaker for use when a headset was not in use. I would also likely include BT for the BT headset I tend to use and an optional/selectable built-in touch keyer for CW ops (either built in touch keyer or external paddles).? ? I don't operate digital modes very much so I doubt I'd include the GPS module.? ? Anyway, just thinking through the possibilities atm... ? Thanks to those who responded and 73 to all, Robert VE7ZN ?
Randy Paulson All Messages By This Member #145558 Robert, I did something similar to what you are considering. Sounds like you might be envisioning the front panel mounted 90 deg CCW from mine.? I'm attaching a couple pictures. I can supply more detail if you're interested. There are also a couple of speakers inside, mounted to a shortened QMX+ Dev board. -- Randy, N4OPI IMG_6763.JPG IMG_6767.JPG
