If used with a 1 Watt amp as suggested in the article this transmitter is illegal in the US, and that is likely the case even without the amp.

This article was published in South Asia.
The power input to the oscillator can be lowered and with a proper
Low pass filter it would be legal in the US.

You cannot simply assume that it is legal. Have you conducted field intensity measurements that would be acceptable to the FCC?
