[CQ-Contest] Low Power Change to ARRL Contests

Sun Dec 26 22:13:00 EST 2021

 My first contesting rig was a Yaesu FT-101E.  Max power was about 150W.  Wondering if this was due to the ARRL rule.

 What I remember is that the limit was originally 100W (50's and early 60s)

Then the rule was upped to 150W when most transmitters/transceivers were
running tube finals (like a pair of 6146's) which easily put out between
100 and 150W.

Then came the solid state rigs that only ran 100W output. But some low
power folks started using an amp to get them up to 150W.

And then finally we get to this last rule change taking it back to 100W.
Actually setting the low power category output to be 100W makes sense to me.
