Analyzing FCC amateur radio license issuance data, this resource presents monthly graphs and raw numerical statistics detailing the number of new and upgraded amateur radio licenses. The primary focus is on the impact of the Element 1 Morse Code test removal on HF privileges, specifically observing the transition rates from _Technician_ to _General_ and _Extra_ class licenses. Data is sourced from _QRZ Archives_ and processed using a custom Perl script to tally "Issued" licenses each month. The presented data, available in graphical, tabular, and raw XML formats, clearly illustrates the "spike" in General class upgrades following the rule change. It also highlights a consistent rise in new Technician licenses observed in March of both 2006 and 2007. While the dataset currently extends back to January 2006, providing a limited statistical snapshot for long-term Technician trends, it effectively captures the immediate climb in General class licenses.
