Of these, 820 are in the &#8220;lower 48.&#8221;  <br>Some prefixes such as NP0 and NP1 have no calls issued now and may have never been issued. <br><br>This analysis of callsigns is based upon a master file received from AA3B, the WPX SSB\/CW Director.  The table was prepared using a custom data analysis script written by N3QE.  Thanks to Bud and Tim. <br><br>Of the 930 possible prefixes, 480 were active and 450 were inactive. 248 prefixes had only one active station. The activity drops off for two or more stations. <\/p>\n\n\n\n<!--more-->\n\n\n\n<p>N3 is the most popular US prefix with 41 instances. The &#8220;traditional prefixes&#8221; such as K1, N1, and W1 are well represented with more than 20 active stations. <\/p>\n\n\n\n<p>Here&#8217;s the table of active prefixes. The blanks (holes) represent inactive prefixes. There are patterns of holes. <\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">AA0 AA1 AA2 AA3 AA4 AA5 AA6     AA8 AA9          \n    AB1 AB2 AB3 AB4 AB5 AB6 AB7 AB8 \nAC0 AC1 AC2 AC3 AC4         AC7 AC8 AC9   \nAD0 AD1 AD2     AD4 AD5         AD8  \nAE0 AE1 AE2     AE4 AE5 AE6     AE8 AE9\n        AF2     AF4 AF5 AF6 AF7     AF9    \nAG0 AG1 AG2 AG3 AG4 AG5 AG6 AG7 AG8 AG9\n                        AH6 AH7   \nAI0 AI1 AI2     AI4 AI5 AI6 AI7 AI8   \nAJ0 &nbsp;
