Submerged radio messages

I apologize for going back and editing the previous post, but I didn't want something incorrect in the record.
It turns out that 20 meters is the deepest depth that is both below periscope depth and also able to pick up messages. However, if the depth goes just slightly below 20m then no messages. So 19m is the best. Periscope depth is known as the danger zone because of the risk of colliding with surface vessels.
However, 19m is still not enough to clear all surface vessels. After more testing I found that even 21 meters is not deep enough, you can get your conning tower smacked by a large tanker. In order to be safe, I am going to be setting my cruising depth below 21m, 25m as Hooston said sounds good. That means to receive messages you have to come up to 19m "comms depth" at certain points in submerged cruising.
And yes, the conning tower can get exposed in rough weather at periscope depth- the game models this- it's probably worst in a Type II. I have never been spotted by aircraft at periscope depth, so is probably not modelled in the game. Still, nice to have a camo paint scheme in the Med, just in case.
All of this is what I found running GWX, I don't know if other mods are different.

Reason: Further testing shows 21m too deep for messages, and 19m too shallow to avoid collisions.
