Welcome to Charlie Tango.
You'll have to forgive me but I had a bit of a giggle at the 'silent key' reference and thought the forum had turned into a Ouija board - that's usually radio talk for someone who has unfortunately passed away.
I knew what you meant though, you've been 'off-air' for a bit and I hope your new radio as well as a call sign helps you back to it all.
Call signs are usually issued most days so keep an eye on this posting for when you are allocated yours.
Our main man who issues them is currently on a well deserved break but he's so amiable he's been checking and issuing them whilst on holiday(!) He really does a grand job.
All the best,
