What the Federal Clown Commission cares or doesn't care about is immaterial. I don't want to have to listen to it.
One wonders these days what the status of FCC enforcement is. Although evident in selective cases other obvious infractions are not even investigated. In this one particular case the in band inter-modulation distortion let alone the harmonic spurs ruin it for everyone. Not just the near field but when propagation takes hold, the whole world. I have plenty of man made noise here because of lax regulation and enforcement without having to contend with the world's second worst source of radio interference.

I see from other posts you already get the idea. Just in $$ alone it doesn't make sense.
Now onto your station .
An antenna(s)

Just one of many ideas.
Radio.
You don't need the latest greatest but the farther back you reach the more knowledge you need, the more experience you need, the more hard to find parts you need. I'm now on the edge of not recommending the Kenwood hybrids to a new amateur. Although the three tubes are still inexpensive and available the rest of the radio is showing it's age. Better to find a solid state rig with all that you need to get started rather than all you want.
Amplifier.
With an effective antenna system the want for an amplifier diminishes somewhat. Eventually though an amplifier becomes a priority after others are met.
The AL 811 in any of it's iterations is a beast all to its own.

This is the gospel according to the man that designed it. Deviate from his experience and advice at your own peril.
Heath SB-200.
Better for it's 572B's but still read W8JI on the 572's
AL-80(b)
A real transmitting tube at last. A step up but still adhere to the limitations.
Heath SB-220.
If one 500z is good (AL-80) , two is better , right ?
Ceramic/Metal transmitting tubes.
Open your wallet, build your own, or both. At this point you know enough to not electrocute yourself or destroy a tube on contact.
Wild card. LDMOS
There are many suppliers of complete amplifiers and kits. Do your homework. The advantage here is that although you may have around 110 Amps of 48 volt DC on the desk you don't have to contend with 3500 volts DC @ 2 Amps.
Best wishes on your coming exam. Study as hard for the General as your Tech. Hope to put you in the log one day .
