Yes, it's very cool! But don't use it to transmit in practice though. The output is very dirty because it produces square waves which generate a lot of harmonic

Yes, it's very cool! But don't use it to transmit in practice though. The output is very dirty because it produces square waves which generate a lot of harmonics (emissions on unintended frequencies). You can use this safely if you know what you're doing but only with a lot of filtering. Or by not transmitting as such but outputting into a receiver directly with some attenuation.
