The UK has 3 licensing levels, foundation, intermediate and advanced. Aside from the allowed power output going up each time (10W, 50W, 400W) are there any other privileges one would gain?
OK, I'm a mere Foundation Licence holder, but other than the increased power, no extra privileges open up at Intermediate Level - it is only with the Advanced/Full Licence that the extras arrive
Foundation and Intermediate licensees cannot operate Special Event or Club Calls except under supervision, and cannot operate on LF or 5MHz.
The other bonus for Advanced Licencees (not available to Foundation of Intermediates) is to operate as Maritime Mobile (at sea) or overseas (under CEPT reciprocal terms)
-- Edit: At the time of writing the first sentence was correct... but within seven months of that post, I'd progressed through the Intermediate to the Full Licence... but the answer still holds!
