This (me) pre 1987 Tech decided to do a paper upgrade to General, but while
I'm at it, might as well go for it and got the Extra. Took some
practice tests
on the web and did well enough to make going for it a no brainer. I had
dabbled
with HF years before on 10 meters novice enhancement SSB subband, and
I figured I wanted to upgrade to get more privs on HF. Upgrading also
"locks
in" credit at the FCC for the 5WPM and General written I passed back in
1976 to get
my pre 87 tech.
