Hello Greg As far as I'm aware there isn't any race condition. Something else must be at fault here. The TX line is deactivated and after some short delay, RX is activated. And vice versa on key

The wiring is correct in the assembly manual. It is not uncommon to forget to install the jumper in JP501 (shown in the diagram at the bottom of pg 36), which connects the BNC to T507 output. It is

One new quirk I found on 1_01_003: In the terminal interface, when you exit from the Diagnostics screen, it now changes the band in the QMX VFO, rather than leaving it set to whatever it was before

Most of them happen immediately.? That was the intent. By experimentation, I have found that a couple of them still require you to exit to a higher level menu before they take effect, in this 03

Can anyone confirm the wiring to the PCB is correct in the assembly manual ? Fired up my new QMX for the first time and was somewhat upset that everything was working but no signals were passing to or

Tnx Stan, tnx Chris. That makes it clear. 73 Chris

Yes C504. ?Fat fingers I use this from DigiKey: 399-4701-1-ND -- 73 Jeff Moore W1NC

Thank you very much Stan! Will try in the evening. BR/Sergey UB3AZK

I can print them faster than I can assemble them. I have 3 3d printers at my disposal. My biggest hold up is waiting for Amazon to send parts when I run out. Interestingly the bubble mailers that

Howard, Here is the KobiConn parts number from Mouser: 161-5435-EX As a TRRS Jack the following pinout is expected. See PDF drawing attached. Pinout: Contact A is Tip Contact B is Ring 1 Contact

The strange thing is that this was a working QMX+ until I initiated the upgrade. Thinking back on the procedure I did was: Initiate upgrade from menu. After QMX+ drive recognized by compute, go into

Hmmm...? sorry to hear that. I have upgraded 3 of my QMX, and downgraded 2 of them, and never encountered a problem with the receive audio. So this is certainly not normal. And yes, Factory Reset

If you make a parameter change in the terminal, say turn off CESSB, is the change immediate or do you have to exit terminal mode or exit the sub menu? Glenn VK3YY.

I failed to mention that a did a factory reset in both versions and that no stations can be heard through the receiver. The menus are completely traversable. My gut makes me think that the stored

If you want help printing the cases I can make a few. [email protected]> wrote:

Maybe a conflict with one of your settings?? (there shouldn't be such a thing, but there are still unknowns in the new version...) Try a Factory Reset, which will restore original factory

I was excited to try SSB on my QMX but my microphone was in my home QTH Michigan. I ordered the electret element that Hans recommended and assembled a microphone from spare parts. About $20. I

I was excited to load the beta SSB firmware on my working QMX+ Transceiver. It was originally running version 1-00-27 very well. ?The SSB firmware loaded apparently fine and booted up. however it

Open device Manager and expand the Ports (COM & LPT). You will see one or more COM ports, one of them is the QMX. You can determine which one by unplugging the USB cable and see which one disappears.

I second that. I have several times tried to transmit after having checked SWR, only to discover that the QMX display still says "Tune SWR" or "Hardware tests" - and nothing is
