Hi Pinto
I agree that a fixed installation is better than a portable in many respects.
And also agree that ICASA staff are all generally friendly and helpful. BUT I'm sorry to rain on your parade. If I understqand your post correctly, you are only half way there
For a VHF you need TWO things. One is a licence to posess it ( which you have got) and sometimes called a "ship station licence" , and ANOTHER to operate it for which you have to sit an exam. The exam itself is not difficult but only once you have passed it will you be issued with an OPERATOR'S licence.
So for two radios you will need 3 documents. 2 x ship station licence, and 1 x operators.
Check it out ! If I am wrong, I owe you a beer ( or two).
Cheers
Johnno
