I boosted the Range of my Transmitter, but not sure why.

I made a shortwave transmitter, but today I modified it.

The frequency is 7.328Mhz.

The drawing attached is of the final output stage to the antenna.

Circuit #1 is what I had and was able to reach approx. 100 feet.

Circuit #2 is what I now operate at and now reach 1500feet.

What I'm not sure about is what caused this increase in range?

Was it the increase in current or the RFC ?

For one, you are no longer dissipating power in your collector resistor. That power can now be used by the transistor.

Yeah I think about that all the time, I'm out of the band plan I know, I wanted to work the 40 meter band. Yes I'm licensed in that band
But going back to the shortwave transmitter I wonder, who's even listening? I would be so pleased if they actually found me.

So far no complaints
