In the early 80's I was teaching 98C at Ft. Devens. The overview lesson plan had us teaching that CW was no longer used.
At the same time there were 05H (058 for you old people, 98H for the post VN folks.) classes being taught across the quad.
My first MOS was 05B1A4. HF, CW, and wire antennas are still in my blood. (468/f[MHz] anyone?)
