Amateur Radio? Answered

 I am going to be taking an amateur radio course early next year (foundation level). I have been doing a little research into the subject and I am baffled by the terminology / acronyms. 
I'm sure I'll learn all that when the time comes.  At the moment I am interested in cheap kits / second-hand gear and instructions on how to make a small, portable aerial for 2m (144MHz) operation for www.sota.org.uk.

Any other information is gladly accepted.
What is CQ, SSB, CW, QSL? etc.

With regards to kits, there are many available. They ae on eBay on you can find them at radio rallies.
For a 2m sota aerial, a 3 element Yagi would probably be best as it issmall and directional and provides some gain over a dipole (type 3 ele 2m Yagi into Google for more information).
CQ is the initial call put out by a ham. SSB, which stands for Single SideBand, is a very common mode of communication which can be used for long distance contacts. CW stands for Continuos Wave and is aother name for Morse code. Finally, a QSL card is a ham postcard that is sent to confirm that a contact has taken place. Details such as the time , date and frequency of the contact are put on the card.

CQ - that term used to call for a two way communication with someone over the air. i.e. CQ, CQ, CQ, this is K6HZT calling CQ.
SSB - Single Side Band, This is where you take an AM radio signal and peel off one edge of it (the sideband) and just broadcast that. The receiver re-creats the rest of the signal.
CW - Continuous Wave. This is the most rudimentary for of radio. It is nothing more than a carrier with no modulation that turns on and off. CW is the type of radio used to transmit Morse Code.
QSL - This is a written confirmation of a two way communication. Usually in the form of a post card, trading QSL cards is a basic tennet of Ham Radio.
