Hi,
I've just finished my QMX+ rev.3 (firmware 1_00_027).
Everything seems to be working correctly, except for the SWR and PWR does not show.
They don't appear on the LCD, even though I have them enabled ON in the setup.
The LCD display is working properly, showing the battery icon and clock, frequency, etc.
Any advice would be welcome
Thank you so much!

Same Issue with mine.? QMX Rev 4, firmware 1.00.027.? No PWR nor SWR showing up. f/w issue?

?

thx

I've tried the "TUNE SWR" in "Hardware Test" and it works perfectly.
If I transmit, PWR and SWr indications don't appear on the top right side of the LCD display.
I have the "Display " option enabled in the setup.

Doesn't show on my pre-assembled unit, either. But since they haven't bothered to put out a QMX+ operating manual, I can't be sure it's supposed to show.?

I see power and SWR displays with my QMX+ firmware 1_01_003 in CW, digital, USB and LSB modes.

I don't recall it not working on 0_27, I would probably have noticed.

Have you configured it correctly?

Are you actually transmitting?

What modes have you tried?

I've tested it in DIGI mode.
And yes, I'm transmitting on multiple bands and everything is OK.
Another colleague is reporting the same issue on QMX+ Rev 3 with the latest firmware.
I've tested it with the beta SSB firmware and the same thing happens. There's NO POWER or SWR indication.

What does Hans's comment mean?
That there's no TX PWR & SWR display on the QMX+?

Hans' comment means that you need to read the QMX/QMX+ operations manual, and the correct data is there.

Yes, the power and SWR meter work on both QMX and QMX+.

If they are not working, it is possible that you didn't use the display/controls menu to properly enable them.

Or perhaps your T507 transformer is not properly soldered in, such that the CPU can't measure any forward/reflected power.

I have never seen the indicators malfunction in any of the firmware versions I have used, on either my QMX or QMX+ units, but it does depend on the T507 hardware is working properly.

Note that the receive S-meter and AGC meter do not work in DIGI mode, only in CW mode, because AGC is only implemented for CW.

Now it's clear.
The tests are in DIGI mode, that's why SWR & Power don't appear during TX.
