Tested and works as it should. There is one portion (one arm) of one display segment missing. As in the picture. But it is minor and doesn’t affect the reading of the fequency. Price is firm.

Compact, battery‑powered unit designed for field use and general RF troubleshooting. It remains popular among hobbyists because it covers a very wide frequency range for its size.

Frequency coverage:

• 1 MHz to 1300 MHz
• Designed primarily for antenna‑based pickup

• Can accept direct input via BNC

Typical usage:

• Sniffing local oscillators
• Checking transmitter frequency
• General RF troubleshooting

✔ Works well as a “sniffer”.

Users report that the easiest and safest method is simply holding the counter’s antenna near the circuit or radio under test. This avoids over‑voltage and avoids detuning sensitive stages.

✔ Can detect AM radio IF (455 kHz) indirectly

Even though the counter’s lower limit is 1 MHz, hobbyists note that you can still pick up the local oscillator or harmonics to verify alignment. Techniques include:

• Using a small inductive loop near the tube/transistor
• Using a high‑impedance probe
• Using an active FET probe (MPF‑102, etc.)
