Seeking advice on boosting range of fm transmitter (from a kid's toy)
I just bought the Smartlab: You Build It - Rock Star Microphone toy from a Goodwill. It's a great toy; it has a microphone that let's me transmit my voice over the radio (perfect for a Halloween haunted house when the static-mad radio bursts to life with terrifying voice-overs!!!:) works but only up to about a six foot range.
I would like to be in a different room and use the microphone but I need to boost the range considerably - I understand that the FCC has rules about this. Moving forward, I don't know how to do this (at all....). Are there commercial range boosters that I can use? Are there mods that someone can recommend? Are these toys designed to NOT transmit beyond six feet even with mods? I wish I could give more information about the tech specs of the toy but I will have to try to de-solder the metal plate covering the circuit board (plus I don't know what specs to look for yet).
