I don't think it is just me that uses QMX as an HT, so there can be different versions of QHX. This is about my version of QHX, integrated with the 2s 14500 batteies and the micro-size single lever paddle.
I didn't think I would need a log tray like KH1's, because I've been using my phone's note app for writing the logs. But when my one hand is already occupied by the HT and the other needs to stand by for cw keying, using the smartphone for logging is not convenient anymore. So here's a quick dirty prototype made with a thin plastic sheet. Someone would make a much nicer one with a 3D printer, I guess.
When it is closed (folded) it works as the screen protector (partially protecting the micro cw paddle as well) and also the volume button stopper to prevent the radio from accidently turning on. The metal hinge is scavenged from an old eyeglasses case, and maybe I can attach a steel pen with some magnet on it.
Opening it up, I can use it as the logging pad, though the pad is small and not so comfortable for writing anything well. The clear plastic sheet is from some product packaging, and it is not very firm. Some harder material would be more stable for writing on. For the logging sheets, I would be using Post-it cut for the size. Maybe a few sheets would be enough for about 10 QSO's or an hour of handheld walkabout operation.
