Well..as someone who graduated from that course about a week ago I can probably help...though with the point that the course is changing pretty rapidly and your mileage may vary as some friends of mine are on a course about a month behind and its different already.
-Typing (If you can do 30ish wpm you get exempt)
-Radio Theory
-Crypto and COMSEC
-Electrical Theory (Reallllly basic)
-The MS office suite (PP, Excel, Word, Outlook)
-Basic lines, CAT-5e/field line
-CI's & the 522
-You do some computer tacnet stuff (SAS/Blue on Blue/etc)..this one seems to be all over the place, some courses got in depth with this, others didn't
-Counter IED
-A few random classes here and there such as field antennas that they never come back on and you never get to actually do any hands on in (a shame really
)
-A couple other radios and systems
Then you go to the field for a month or so, lots of tasty boxed lunches
-Putting the 40ft mast up and down a lot
-Setting up an LSVW comms det
-Setting up the Generator
(You seriously spend almost a month doing the above three)
Then a field EX...(not really an EX, its like a few days and most courses slept in their shacks at night)
You do some IST/CST/LST and some core, most of it introductory and not graded
Any other questions just ask.
