Re: QCX mini with straight key
I also take from this single poster, that no one else has had this experience? If so I can get around it by using a paddle, I can also try using a bug.

Re: Another QMX+ got onto the air + Low Tx Output
I've now sorted the power problem on 6m. It appears that the inductors L519 & L520 are super sensitive to turns spacing, tweaking those improved the O/P power, but the main improvement came when I

Re: QCX mini with straight key
Is it possible that is the sidetone sounding a little soft?? Maybe you could record a little of the sound and post it so we could get a better idea.

Re: QMX Carry Case
I am also a fan of the 1050 case.
Additionally, I have this 3D printed cover ( QMX cover and desk stand for hamradio POTA SOTA by F4EGX - ( https://www.thingiverse.com/thing:6599009 ) Thingiverse)?

Re: QMX (1_00_020) SWR - Issue?
If this were me I would first completely calibrate the VNA for a bandwidth of 13.8 MHz to 14.5Mhz to zoom in on the 20m band, so that you can accurately read the Return Loss across this narrow

Re: Info QCX mini
I like this Anker speaker too.
Battery lasts very well, sounds good with QMX.
Also sounds good with music, with good Bluetooth range.

Hi Chris
Software.
I don't think they're flattened. It's a limitation of my ASCII art, I think
that's all. Everything on the terminal has to take place within the
constraints that there are 25 rows

QMX (1_00_020) SWR - Issue?
My QMX was delivered the other day but I have not been having a very good
time with it so far. I am really hoping it is because I am just dumb!
It came shipped with the 1_00_019 firmware. I put 11.7v

Re: #qmx IQ Sweep ?

I just wonder why the peaks of the sine waves are flattened.? Is this a hardware or software saturation?

Re: QMX+ on Fire
Problem resolved! Happy again. There was a short on the 3.3V Buck converter, between D102 and Q107. D102 was soldered not precise on track and made contact with Q107. Had to replace the buck

Hi Chris
How do you mean, the "saturation of peaks"??
To me that sweep looks normal, healthy.

It seems spongy like it's forcing the dit and dah spacing if that makes sense.

Any thoughts on the saturation of peaks?
I am seeing similar plots on multiple QMXs.
Firmware issue or Putty issue?

Re: QCX mini with straight key
I'm not sure what you mean. There is a setting in the keyer menu for straight key. The cadence is established by the movement of your wrist and finger.

No, but there were a few times the SWR protection triggered while tuning a random wire that starts a foot a way or so.
