I also experienced radio signal issues today with my Tx16s, but there was no loss of control. Rather I had more jumps in tx power (TPWR) today than usual. My RM Tx12 tx (set to dynamic power on) has a minimum default of TPWR of 25 mw and has less frequent jumps. I am doing a comparison flying the same model using the Tx16 and Tx12 on alternate flights.
I posed this question several says ago on Discord Help and Support and I got some responses including from an expert V-22. My Discord user name is Gregor. This link may access the full conversation:

Title: Dynamic power range on a Radiomaster Tx16s
Is there a way to adjust the dynamic power range on a Radiomaster Tx16s?
I am using edgetx 2.7.1, ands elrs 3.0.1
Packet rate 100Hz full, telem ratio Std (1:32).
At my noisy flying environment the tx defaults to minimum TPWR 10 mw on startup and model launch, but there are frequent jumps to 25 mw, and occasional ones to 50 or 100 mw.
My RM Tx12 has a minimum default of TPWR of 25 mw and does not have frequent jumps.
Can I adjust the Tx16s dynamic range so there is a minimum of 25 mw?
Some points are:
For aircraft a packet rate of 100 Hz full is recommended with telem ratio of 1:32. V-22 says a telem ratio Std (1:32) is fine, it means "Link stats frames are sent ~2x/second, and 1:32 at 100Hz should give you ~3 telemetry frames per second." This means at lower packet rates you can use better telemetry ratios (1:32) providing more frequent updates for the tx which means quicker power jumps when required, eg interference causes the receiver signal to noise ratio to fall.
A post by sunjun (screenshot attached) says it is easy to adjust the minimum default of TPWR of 10mw on the Tx16s to 25 mw. V-22 says jumps are a sign the Tx16s is working properly, and there is no need to worry.

I will add some flight logs in a subsequent post.
