On the way to Africa to give a boost to our economy, AF1 enters NY Oceanic FIR on VHF, then switches to HF for a Selcal check.

What does the phrase mean: "I'm A E M P"... I'm somewhat familiar with SELCAL now. Is that like a xpdr code or something?

That is that particular aircraft's SELCAL code. Each letter designates a specific audio tone frequency. The code is unique to the aircraft, actually belonging to the owner/operator.

Correct. Each letter (from A thru S without N or O) represents an audio tone ranging from about 300hz for "A" up to about 1500hz for "S". When they transmit them they send them in pairs, in this case AE, then MP, each pair in alphabetical order. For example if he said his selcal was M-P-A-E that would be a different, valid code, but P-M-E-A would not because when transmitted the actual tone pairs would be the same as M-P-A-E.
