yesterday, as I was buying electronics, I bought a pair of kids walkie-talkies, so that I can rip one apart, and synchronize my transmitter and receiver with them.
The only controls on the walkie talkies are the on-off switch, a button (when pressed, transmits pulses), and the push-to-talk switch.
After I bought them, (because the price was cheap), I discovered that they were set to only one frequency.
I tested them against my commercial radio. If the commercial radio is about 50 centimeters or less away from the walkie talkie, the walkie talkie can transmit somewhere between 99Mhz and 101Mhz range.
If the commercial is at least 1 meter away, it won't pick any of the walkie talkie signal up.
so the only thing I won't know for sure is the actual (resonant) frequency these walkie talkies are transmitting on.
I'm guessing 49Mhz, but I am not 100% sure.
and the package makes no mention of the frequency.
