It takes time to learn all the "jargon" involved in ham. Take your time and try to slow your mind down to really hear whats being said. Don't be afraid to ask for a repeat of the call sigh. Lord know that many an EXTRA do it more then once during a QSO.
Or it could be a regional thing. I moved from Florida to Nashville and was totally lost with the different forms of "Southern" spoken up here. Been going on 6 years now and still get some real word recognition problems. Different words mean different thing in different parts of the country.
Got to give it to you lad for at least trying to figure it out and for asking for advise.
