The original licence was for use at one location but it was found that does not work for some instructors.
Being an RTC and being and instructor are not joined as far as these radio licence's go.
An instructor can have and buy from Ofcom a licence, they do not have to be a RTC.
If you speak to them and tell them that you worked various locations you as the instructor with you own licence can yes but only if it allows you to travel.
The kit has to be licenced, in wot ever way suits you or your school best.
The RTC is only licenced if that is the name on the licence
If the instructor has a licence that allows him or her to teach and move around it does not matter if the RTC is licenced or not.
This only matters if the RTC has its own simms.
As I said it is the radios that need to be licence, either via a RTC or an instructor.
Told you it would have been easier for you to call me
Anyway Stu are you getting an OHP?
