Nevermind, I should have looked harder at Han's explanation of how the BPF works and is switched, not just the schematic drawing itself. -Nate

Studying the BPF/receiver portion of the assembly manual more, (not just the schematic), and the datasheet for that chip, I think I understand that better now. I then put a 1200pf capacitor (soldered

If there is room that would be great. I power my QMX with a talentcell. I have QMX+ on order and will definitely check that out. Mike Krieger [email protected]> wrote:

I agree with Colin. I have used the ticketing system to successfully change an order. Steve W6WU

I’m happy to see the introduction of this QMX+ version. From everything I’ve seen, it’s using much the same hardware and firmware platform of the QMX and as I see it, will not hamper ongoing

Phill, I'm disappointed too, and fully expect to see plenty of the original QMX kits on FleaBay.? I ordered mine when it was first announced, which would now be a year ago, given that announcement

Note that these devices require that you use a USB-PD source that can deliver 12 volts. That voltage was originally a required part of the standard but no longer is, so some newer supplies may not

I know that the pre-built battery packs are convenient and that they also provide a higher voltage than the radio is supposed to be seeing. There are two ways that (I personally) might use; 1. A

The software package comes as a pre-compiled file; When you first power up the QMX it will appear like a drive when you attach it to the USB port. You just transfer the firmware file over to the radio

Yeah....page 63 of the current (v...018) of the manual.

If it doesn't have software, when you power it on hooked up to a computer it shows up like a flash drive. You download the firmware, unzip it and copy the file contained within the zip file to the

finished my qmx kit and was wonder about the display icons.? i have my unit connected to a computer for using WSJT. I am able to receive signals but I'm not sure if i am able to transmit.? is there

Hello! I've seen on this list concerns about ensuring we use our QMX radios with 12V and not the 13+V which a lot of LiPo and LiFePo batteries are putting out. I've found two options that are both

Thanks Ron! I expected a USB-mini as was stated in the documentation. -Bob

Robert. that is the USB-B connector. The plastic inner piece is part of it. Don't remove it. Ron [email protected]> wrote:

That's what I had done before. Doesn't make much of a difference - squeezed or spread apart - about 1dB on 40 meters and that's it. I guess I'll leave it as is. -- Jim / K7TXA Eagle, ID SKCC 10447T

Building a QDX Mid-Band 40-15m. After struggling with the BPF parasitic resonances (or so I thought)... I bypassed the BPF completely., or tried to....... but my RF sweeps still remain similar!?

Don't see why not.? Maybe in the box. Wonder if it could be fitted before the LPFs and SWR meter. Chris
