A good possibility is the frame was made in April and the entire bike was assembled in June of 1982. It is not unusual for the two dates to not line up and be off by a few months. You have done an excellent job deciphering the date codes. The meaning behind the rest of the serial number has been lost to time! Now all that is left is for you to post some pictures!
In the mean time, a catalog page will suffice. Which model Voyageur, 11.2 or SP?
