Testing Location: Home backyard
Date: October 2025
Equipment:
A low-power UHF CB radio was used as the signal source, transmitting continuously on 477.4125 MHz (Channel 80). Both receivers were placed side by side at various distances to see which one would pick up the signal first.
This confirms that Uniden’s Close Call system — which is purpose-built for near-field signal detection — remains faster and more sensitive at identifying strong, nearby transmitters compared to the Baofeng’s frequency counter, which relies on slower signal sampling.
The Baofeng’s counter is handy in a pinch, but it’s more of a convenience tool — not a dedicated near-field receiver.
Still, it’s great to see both radios perform well in the test, especially in a simple home setup using everyday gear.

Date: October 2025
Equipment:
- Uniden BC125AT (Close Call feature)
- Baofeng UV-17 (Frequency Counter mode)
- TX Source: 0.5W UHF CB handheld locked on Channel 80 (477.4125 MHz)
The Test
This backyard experiment was designed to compare how quickly and accurately two popular handheld radios can detect nearby transmissions — the Uniden BC125AT using its Close Call feature, and the Baofeng UV-17 using its built-in frequency counter.A low-power UHF CB radio was used as the signal source, transmitting continuously on 477.4125 MHz (Channel 80). Both receivers were placed side by side at various distances to see which one would pick up the signal first.
The Results
The Uniden BC125AT consistently had the edge, triggering a Close Call hit about 2.5 meters earlier than the Baofeng UV-17 detected the same signal.This confirms that Uniden’s Close Call system — which is purpose-built for near-field signal detection — remains faster and more sensitive at identifying strong, nearby transmitters compared to the Baofeng’s frequency counter, which relies on slower signal sampling.
Takeaway
If you’re hunting for unknown local transmitters or doing field monitoring, Close Call still wins for speed and reliability.The Baofeng’s counter is handy in a pinch, but it’s more of a convenience tool — not a dedicated near-field receiver.
Still, it’s great to see both radios perform well in the test, especially in a simple home setup using everyday gear.
