UPDATE - THIS TX DOES NOT WORK AS INTENDED, SEE INFO BELOW.
Here is a very crude AM transmitter on the 27.036 MHz band which is about channel 7 on EU CB band. I'm actually not sure for certain if it's am or fm I will update when I figure this out. This is for educational purposes only. Please don't transmit on frequencies you aren't supposed to. A warning, there is no output filter and this will transmit loads of harmonics. A filter must be added to make it clean signal. As always, be aware of legality of transmitters before using them.

UPDATE

This transmitter does not do what I expected, I should have hooked up the audio and I would have realised. it has a strong but very very quiet audio signal on 27.036, and harmonics on 12 MHz louder audio and again louder on 4 MHz, basically it does not work as intended. I am working on another tx that does transmit on the 27 MHz CB bands for a later video.
