I'm in central Victoria (Australia). Installed the latest release. Mic gain needed to be raised to 80 with my microphone. Called CQ and was answered by VK7DD in Tasmania. 5 and 7 with some fading. He

You can test the power supply boards independently, using a procedure which you can find in the wiki for this group, and then potentially repair one by replacing parts. You can also order a new set of

I briefly looked at this some time ago, and discarded the idea.? Headsets for cell phones use a standard for the buttons and mic connections that are problematic to use with the QMX.? You can't

There appears to be a short of some sort dragging down your 5V supply.? This will prevent the display from turning on, and prevent the receiver and transmitter from working properly. If you can put

Two potential issues with this (and prior) versions: 1) VOX unintended behavior When VOX is on, and ext. mic is selected as input:? unless the threshold is set very high, any click of a front-panel

Would this rework also apply to the QMX AND the QMX+? James KA9TII

Would take more than an adapter cable to use a button for push-to-talk. The buttons on wired headsets short out the

Hi, I assembled the QMX rev3, connected it via USB and installed the firmware. I built the 9V version. Firmware is: 1_00_027 ( https://qrp-labs.com/images/qmx/firmware/1_00_027.zip ) I checked via

So saw the new ssb update and got an idea.cellular wired headsets these days are often TRSS and have a button that could potentially be used for ptt. Was debating making an adapter cable by taking a

One unfortunate side-effect of grouping the CW menu items: the firmware no longer remembers the last CW menu items used.? So if I want to quickly change filters, I can't just long-click/click/click

Thank you for sharing your settings. Brien, according to Hans' description, this setting is not a time, but a dB/sec recovery rate.? If so, it seems that what you did was speed up the agc

Yes, first of all you need to use either update 01 or 02; the CAT PTT was broken in the original release. Then these settings worked for me, along with setting the output all the way up to 0dB in the

I realize that settings are dependent on microphone, voice characteristics, etc.? but I thought I would publish my current settings that are seeming to work at the moment.? ?Power output is very

Got it working, had to change the microphone setting to "USB". Band conditions on 40 m weren't great, but I did manage to hit speed level 6 on VARA-HF. If anyone has other settings that would be

Just in case others are experiencing this it appears to be because the MIC AGC is enabled and the recovery time was to short.? I had it at 2.? Bumping it to 10 increased the recovry time and so the

Possible bug or invalid default configuration: SSB -> Mic Noise Gate -> Samples set to [100] on a scale of 0-99.? Making a change to this value enforces the range limit.? What should the default be

As info, the power supply I am using indicates 0.6 amps at 9.15 volts when I believe it's transmitting. Idle is 0.137 amps at 9.15 volts. [email protected]> wrote:

Hans wrote in the thread about the new beta firmware that volume should be set to full (0dB referenced to audio full scale) when configuring digital mode software for use with QMX in SSB mode. I

I’m really curious if the Bearcat BC906w wireless mic could be wired up for this. It would most likely need an interface box with power since it needs 8 volts to operate. I believe a 9 volt would
