I like to listen to the VK2WI Sunday broadcast. It's part of my weekly routine. This week I was able to listen to it lying in a hammock thanks to a new arrival, a small FM transmitter purchased on eBay.
It's synthesised for frequency stability. At 500mW it saturates the house but doesn't go much past the neighbours. On the back there is a BNC connector and it comes with a little antenna. No doubt an external antenna would extend the range.
Internally, construction is of a very high standard:
It came with an over the top switched giant power supply. There is some hum evident in the signal but no doubt that could be improved with a regulated supply.
Over the years I've built many little FM transmitters but they always drift to some extent. It's nice to have something stable like this.
I think there could be a market for a radio station that broadcasts selected podcasts, my latest discovery is The Changelog. Now I can just make my own.
