VHF Noise Generator

I introduce a simple noise generator that can be used as a VHF jammer.

I found this noise generator circuit:

I decided to turn this into a VHF jammer.

I added another stage to the circuit with a power transistor. I found only one type of VHF power transistors in a store near my home, it is the KT606A. According to the datasheet, it's a 350 MHz 2.5W transistor, but with heatsink, the power can be increased a little.

I think the circuit will work with more powerful VHF transistors.

The circuit work well in VHF band, (at least 0.5 meter antenna) but emits very low medium wave noise. I did not test the noise level above FM band.
