Comparing Values In One Column And Inserting Multiple Blank Rows

I am working on formatting a spreadsheet report where the values will change in column A. Here is what I would like to do via a Macro. Compare the cells in column A (e.g., compare A2 to A3, compare A3 to A4, and so on). If the values between the two cells in column A are different, insert three blank rows and set the active cell to the next cell following the blank lines. Example:

if cell A5 is different from A6, insert three blank rows below row 5 and new active cell is now A9 and the comparison would start again. I have been trying to code the macro for this but with no success. Here is the macro I have been working on.

Sub Macro1()
Const NumRow As Integer = 3
Dim StartCell As Range
Dim RowNR, NewCnt As Long
Dim RowCount As Long
Dim Count As Long
Dim intRow As Integer
Dim bFmtComplete As Boolean
RowCount = Application.WorksheetFunction.CountA _
(Range("A1", Range("A" & Rows.Count).End(xlUp)))
bFmtComplete = False
RowNR = 2
Range("A1:J1").Select
' Rows("1:1").Select
Selection.Copy................
