My question.....is navcomm a spec 1 trade?
No.
The thread that you quoted has some good info on the trade. You can also check out
this one. There are alot of comms (and former ones too) on the boards, so any questions you have should be able to be answered. However, since those threads give alot of basics, it might be easier for you to ask specific questions. Also, where are you at in your enrollment process, or is NavComm still just an option?
