Apologies if this is a bit off-topic, but figured you guys might know this.

My call is G7TMG and I now live permanently in the US but haven't got around
to taking the US test yet and want to get on the air using my UK call.

I believe I should use W7/G7TMG (or is it G7TMG/W7?) but do I need to state
the "/" as portable if I live here full time?
Also, I presume that my UK HF privileges are no good in the US due to no
morse test???

Any info appreciated.

Sholto.
