Where the Spy-IL range began
The original design.
Still straightforward.
Spy-IL16 is the original Spy-IL microphone transmitter design introduced in 2006. This model retains its original configuration: an electret microphone, adjustable FM transmission and a connector for a standard 9V PP3 battery.
The 58 × 35 mm enclosure houses the transmitter circuit. Its operating frequency is adjustable with a tuning capacitor. It is a different design from the one-button-tuned transmitters elsewhere in the range.
Audio is transmitted live to a separate FM radio. The unit does not store recordings internally. A receiver covering 88–108 MHz can be used when tuned to the same frequency.

Before you choose
A few useful answers.
Can I use a regular FM radio?
Yes, if it covers the transmitter’s selected frequency within 88–108 MHz. Tune both devices to match.
Is the 9V battery included?
No. Purchase one standard 9V PP3 battery separately.
Is a receiver included?
No. Use your own compatible FM radio or buy a receiver separately.
How is the frequency adjusted?
This original design uses a tuning capacitor, not the tuning button found on some newer Spy-IL models. See the original demonstration.
Does it record sound?
No. It transmits live audio to a separate receiver.
What range and battery life can I expect?
Reception and runtime depend on your receiver, surroundings and battery. No fixed distance or operating time is guaranteed for this model.
What does Original mean?
It refers to the original Spy-IL design introduced in 2006, retained in its original configuration.
