It went well today but im a little worried with the radio,does everyone have this problem when starting out.
I think it's hard for everybody. I found it very hard. Now I have best part of 1k hours and still need to think a bit before making calls.
Like any language, aviation radio is highly context sensitive. After a while, you know what to expect, and this makes it a lot easier.
Unfortunately PPL training is run as an intensive '45hr' course so they drop you in at the deep end, making you do the radio early on. It's easy to get a total brain overload.
