In the mid 70s, my dad wanted me to move up from CB to ham radio. I was a teenager using a 23 channel Realistic Navaho base. He offered to buy my ham gear if I got the novice license.
I studied, but before I could take the novice test, I bought myself a Realistic TRC 448 mobile SSB and ran it as a base. SSB CB was great. Folks were very considerate. Range was decent. I also had a few friends who got their ham tickets at the time. I got to use their rigs a few times, but definitely enjoyed the 11 meter SSB experience more.
Today, SSB radios are much cheaper to buy. The lower price point has opened the door for some sub-standard operators to engage in the antics on SSB that used to be limited to A.M. Still, there are plenty of fine 11 meter SSB operators out there.
