Very simple QMX software request

 

In operating the QMX+ with a non-resonant antenna and a manual tuner, it is unavoidable not to get the 'S' in the display to the right of the frequency from time to time. The 'S' just looks like some feature which has been turned on, but one quickly learns that it is an error message since the transmitter has shut down due to high SWR. By the way this is a very nice feature compared to e.g. the QDX and it has probably saved a lot of BS170's already.
?
But my wish is that the 'S' could be made more visible - for instance that it would blink on and off - thus alerting the operator that something is wrong.

Hi Sverre?

Yes no problem, I can add that to my list... Flashing S?

My preference would be that instead of shutting the power off a high SWR would switch to the Tune power, then when the SWR improves the power is restored (ideally after a delay).? This avoids the need to do something other than using the tuner to get a low SWR while still keeping the QMX safe.
?
This may be a bit more work but would make operating using a tuner much easier.

OR...one could switch to their trusty Yaesu FT-450D, as I do, during antenna "tuning" :0)

In relation to this topic, is there a shortcut to the "tune SWR" menu? It would be very convenient to access this menu with a simple key press rather than navigate the menus, particularly when using an ATU, to facilitate band changing.
?
If there isn't already one, could I suggest a long press on the "Tune" knob to take us to the Tune SWR menu? If there is one that I missed, apologies!

Many thanks, Hans, for your Herculean efforts with this firmware. It must have taken huge effort to create it in the first place and your responsiveness to issues has been superb! I'm loving it! I hope that you managed a break, although I've still seen responses trickling in on the forum!
