Hello:

Newbie questions, please.
Getting back into hobby.

What are the "Distress" frequencies used these days for Aero and Maritime ?

a. Maritime:

e.g., is 2182 used anymore ?
If still used, what mode; USB ?

I read that:

"In 1999, 2182 was replaced by 2187.5 as the International Distress
frequency. This new frequency asisignment is part of the new GMDSS
service required on vessels over 310 tons. Use of 2182 will be phased
out and replaced by digital (DSC) watch on 2187.5."

Is this 2187.5 being used now ?
Is it only digital ?
If not, mode ?

Other maritime distress freq's and modes ?

b. Aero:

What are the aero freq's commonly used for emergencies, and their modes ?

c. What is 11.175 used for ?

Much thanks,
Bob
