Noob question regarding 75mhz vs 40mhz

[bigdave]

The lower in MHZ you go the better the signals will penitrate the water.
75 MHZ we use is actually the worst of the allotted RC freq.
72-50-40-35-27 all being better.
Only 27, 50 and 75 are OK with the FCC. And 50 needs a ham license.
But running a sub any deeper than you can see it takes all the fun out of running it.
Might as well stand there with a transmitter in your hands and pretend. Lol BD

I'm the same way with drones I like to take it places I can't go to but can be there with my Fat Shark goggles. I want to make one thing clear though, I stay away from residences and airports I don't need to attract any trouble.
