The TinySA Ultra is super helpful for evaluating the congested 2.4GHz range on set for follow focus, wireless sync, etc. The hardware could be improved with a capacitive touchscreen, but other than that the form factor and connectivity is great. I'd like to see the ability to define & overlay channel information for various channel sets (Preston, Ambient ACN, wifi) to help with coordination efforts, but some console tape and a 0.25mm pen works in a pinch.Recommend setting the LEVEL config to the following fixed values so the auto gain control doesn't jump the line chart and waterfall all over the place all the time:- `LEVEL → REF LEVEL` from AUTO to 0- `LEVEL → SCALE/DIV` to 10- `LEVEL → ATTENUATE` from AUTO to 0
