A practical starting kit
Check the transmitter.
Hear it below 88 MHz.
Spy-IL10 includes a basic pocket receiver so you can check that the microphone transmitter is working and receive its audio at 77 MHz. You do not need to source a radio for that initial setup.
Many ordinary US FM radios start at 88 MHz and cannot receive the supplied frequency. This included receiver starts at 64 MHz, allowing reception at 77 MHz. Operating below the broadcast band does not guarantee freedom from interference.
The transmitter sends audio live; it does not store recordings internally. The compact receiver is intended as an economical checking and listening solution, rather than the option for maximum distance.

A receiver for checking and listening.
The included pocket radio is a basic, low-cost way to receive the transmitter below 88 MHz. Similar receivers are sold separately for approximately $10–20; prices vary by seller.
The transmitter can work over longer distances.
With a more sensitive compatible receiver, the transmitter’s stated maximum is up to 700 m (about 2,297 ft) in favorable open-area conditions. This is not the range promised for the supplied pocket radio.

Before you choose
A few useful answers.
Why is a small receiver included?
It provides an economical way to check the transmitter and listen at 77 MHz, below the range of many ordinary US FM radios.
Is this a 300 m or 700 m kit?
With the included pocket receiver, the stated open-area maximum is up to 300 m. The transmitter can reach up to 700 m with a more sensitive compatible receiver under favorable conditions. Neither distance is guaranteed.
Can I buy this type of receiver separately?
Yes. Similar basic pocket radios are sold separately, typically around $10–20 depending on the seller. One is already included in this kit.
Are all batteries included?
The two CR2032 transmitter cells are included. The two AAA cells for the pocket receiver are not included.
Can I change the frequency?
The transmitter supports 76–110 MHz adjustment. Choose a frequency supported by the receiver and tune both devices to match.
Does the device record audio?
No. This is a live FM audio transmission and reception set.
Is 77 MHz free of interference?
No. It is below the usual US FM broadcast band, but other signals and local electrical noise can still affect reception.
