Bugging device mk2

This is a room transmitter that basicaly transmits audio that it can hear onto a wideband radio frequency.

The tuning range is roughly between 88-108 mhz
It works up to around 200 meters line of sight.
You can receive its audio using a car stereo or similar radio receiver.It is ideal for use as a baby monitor or listening to wildlife etc when being in the area would disturb the animals. I was amazed to here the noises that hedgehogs make at night using this device.
It is for educational purposes only.
The kids will love listening to birds etc without frightening them away
The microphone has excellent capabilities and a dripping tap in the same room sounds very loud.
There is no way to record using this device it is a transmitter only.

Ive not done any work on this project in years but thought I would use some surface mount components and reduce the size of the device so here is mk2
