Here is our complete comparison of all ten frequency counters. This table gives you a quick look at frequency ranges, key features, and what each unit does best. Click any product name to jump to the detailed review.

Each of these frequency counters serves a specific purpose. The portable handheld units excel at field work and identifying unknown frequencies on the go. The benchtop units provide superior accuracy and sensitivity for lab work and precise alignment tasks. The DIY kit offers educational value alongside basic functionality.

1. ASHATA RK560 – Budget Portable for Walkie-Talkies

I tested the ASHATA RK560 with several Baofeng UV-5R radios and a couple of Motorola business band units. For basic frequency identification of handheld radios, it works surprisingly well considering the $22 price point. You hold it near a transmitting radio, press the button, and it captures the frequency along with any CTCSS tone being used.

The unit is incredibly compact at just 2.17 inches wide and under 3 ounces. It fits easily in your pocket alongside your radio. I found it particularly useful for field day events where I needed to quickly verify repeater input frequencies without programming them into my radio first.

The 50MHz to 2.4GHz range covers all the VHF and UHF ham bands plus most commercial and FRS frequencies. However, you need to be quite close to the transmitting antenna for reliable readings. I found 6 to 12 inches was the sweet spot. Much farther and the readings become unreliable or fail to register.

The main drawback is the display. There is no backlight, making it nearly impossible to read in low light conditions. The screen is also quite small with basic seven-segment digits. If you have older eyes, you might struggle to read it without good lighting.

Best Use Cases for the RK560

This counter excels as a backup tool for emergency communications and field operations. I keep mine in my go-bag with a fresh 9V battery. It is perfect for quickly checking what frequency a new acquaintance’s radio is programmed to, or identifying active repeater frequencies when traveling.

It is not suitable for bench work or precise alignment tasks. The accuracy is adequate for identifying channels but not for calibrating oscillators or verifying transmitter offset. Think of it as a “what frequency is that” tool rather than a precision instrument.

2. Walfront DIY Frequency Counter – Best for Learning

The Walfront DIY kit arrived as a bag of components and a small PCB board. Assembly took me about two hours with a basic soldering iron. This is clearly designed for electronics enthusiasts who enjoy the building process as much as using the finished product.

Once assembled, the unit measures frequencies from 1Hz up to 50MHz with reasonable accuracy. I tested it against my calibrated benchtop counter and found it within a few Hertz on signals below 10MHz. The 5-digit LED display is bright and easy to read from across the room.

Where this kit really shines is crystal oscillator testing. I used it to verify the 27MHz crystals in several CB radio projects before installation. The programmable add/subtract frequency feature lets you account for IF offsets, which is handy for radio alignment work.

The power options are versatile. You can run it from USB power, a 5-12V DC adapter, or a 9V battery. I typically use a USB phone charger brick on my workbench for convenience.

Be aware that the frequency counter function needs a fairly strong input signal, around 5-6V peak-to-peak. Weak oscillator signals might not register. The crystal tester function works better for low-level signals. Also, the assembly instructions have some translation issues, and the product photo shows incorrect component placement for J1 and JP1. Double-check the silkscreen labels on the PCB.

Who Should Buy This Kit?

This is perfect for students learning electronics, hobbyists who enjoy building kits, and anyone needing a basic frequency reference without spending much. At $17, it is cheaper than a restaurant meal but teaches you about counters, prescalers, and display drivers.

It is not suitable for professional RF work or situations requiring portability. The assembled board has no case unless you 3D print or fabricate one yourself. I mounted mine in a small project box with BNC connectors for the inputs.

3. ciciglow Portable – Weather Resistant Field Unit

The ciciglow portable frequency counter looks nearly identical to the ASHATA RK560 but adds an IP56 water resistance rating. I tested this by using it during a light rain at a public service event. While I would not submerge it, the splash protection gives peace of mind for outdoor use.

Performance-wise, it reads frequencies in the 50MHz to 2.4GHz range with decent accuracy. I found the margin of error to be within a few kilohertz on VHF frequencies, which is acceptable for identifying channels but not for precision alignment. The unit successfully decoded CTCSS tones from several repeaters I tested.

One frustration is the display behavior. The captured frequency flashes on screen briefly rather than holding steady. You need to be ready to read it quickly. There is also no backlight, making nighttime operation difficult. Consider carrying a small flashlight if you plan to use this after dark.

The battery compartment requires unscrewing four small screws to change the 9V battery. This is secure but inconvenient in the field. I recommend using a quality alkaline or lithium 9V for longest life.

Where This Counter Shines

This is my go-to counter for outdoor events, emergency response situations, and any environment where weather protection matters. The IP56 rating means dust and light rain will not damage it. I have used mine at Field Day setups, marathon support events, and search and rescue training exercises.

The water resistance comes at a $3 premium over the basic RK560. For most users, that small extra cost is worth the added durability. Just remember that neither model works well with digital modes beyond basic analog signal reading.

4. Surecom SF401 Plus – Editor’s Choice for Ham Radio

The Surecom SF401 Plus is the frequency counter I recommend to fellow ham operators most often. At around $44, it offers features that used to cost hundreds of dollars. The key differentiator is digital mode compatibility, specifically DMR (Digital Mobile Radio), which most cheap counters cannot handle.

I tested the SF401 Plus with my Tytera MD-380 DMR radio and several Motorola MOTOTRBO systems. It correctly identified the frequencies even when the digital signal was active. For analog FM signals, it also reads and displays CTCSS or DCS codes, which is essential for accessing repeaters with tone access.

The TCXO (Temperature Compensated Crystal Oscillator) provides better stability than basic counters. Accuracy is rated at plus or minus 2 to 4ppm across the operating temperature range. In my testing against a GPSDO reference, it stayed within 200Hz at 146MHz, which is excellent for this price class.

The four-button interface takes some getting used to. The manual is poorly translated and confusing. I recommend searching online for tutorial videos rather than relying on the paper instructions. Once you learn the button combinations, operation becomes intuitive.

The signal strength indicator is genuinely useful. It helps you position the counter at the optimal distance from the transmitter for reliable readings. I found holding the antenna within 2-4 inches of the transmitting antenna usually gives the best results.

Why This Is Our Top Pick

The combination of analog and DMR support, CTCSS/DCS decoding, wide frequency coverage, and USB rechargeable battery makes this the most versatile portable counter under $50. It handles everything from CB radio at 27MHz through 2.4GHz WiFi testing.

The IP66 rating provides dust and water jet protection. I have accidentally dropped mine in a puddle and it survived without issue. The included lithium battery charges via micro-USB and lasts for many hours of intermittent use.

5. ANYSECU SF-103 – Enhanced HF Coverage

The ANYSECU SF-103 is marketed as an upgraded version of the SF401, and in several ways it delivers. The color display provides more information at a glance, showing signal strength, battery level, and mode indicators simultaneously. The frequency range extends down to 2MHz, theoretically covering the 160-meter and 80-meter amateur bands.

In my testing, I found the accuracy to be excellent. The unit consistently read within 0.001 MHz of my reference counter on VHF and UHF frequencies. CTCSS tone detection was accurate and reasonably fast. The ability to read frequencies from 50 feet away or more is a significant improvement over cheaper units that need to be practically touching the antenna.

The DMR functionality works as advertised. I tested with several DMR repeaters and simplex channels, and the counter correctly identified the frequencies. However, I found the digital mode setting difficult to locate in the menu system due to the non-intuitive user interface.

One significant drawback is the battery design. The internal lithium cell is soldered in place and not user-replaceable. When the battery eventually degrades, you will need soldering skills to replace it. The use of an outdated micro-USB connector instead of USB-C is also disappointing in 2026.

SF-103 vs SF401: Which to Choose?

Choose the SF-103 if you need HF coverage below 27MHz or want the extended reception range. The color display and additional information make operation slightly easier once you learn the interface. Choose the SF401 Plus if you want replaceable batteries and do not need HF coverage, as it is slightly cheaper and has a proven track record.

Both units suffer from poor documentation. Plan to spend some time experimenting or watching online tutorials to learn all the functions.

6. LATNEX FC-2800M – Mid-Range Professional

The LATNEX FC-2800M represents a step up in quality from the generic Chinese counters. The build quality feels more solid, and the company backs the product with a 2-year warranty and technical support via phone and email. I found their support responsive when I had questions about operation.

The low PPM crystal time base provides higher accuracy than basic counters. In testing against my reference standard, it maintained within 100Hz at 146MHz, which is excellent for a portable unit. The signal strength indicator helps optimize positioning for reliable readings.

For GMRS, FRS, and VHF/UHF amateur use, this counter performs well. I tested it with various handheld radios across the 2-meter and 70-centimeter bands with consistent results. The built-in DCS/CTCSS decoder correctly identified access tones on local repeaters.

However, the advertised 27MHz CB coverage is problematic. When testing with several CB radios, the counter failed to read frequencies reliably in the 26-27MHz range despite specifications claiming coverage down to 2MHz. If CB alignment is your primary need, look at the Delta DFC100 instead.

When to Consider the FC-2800M

This counter is ideal for amateur radio operators who want better accuracy and warranty support than the budget options provide. The 2-year warranty adds peace of mind for a tool you will likely use for years. It is particularly well-suited for GMRS operators who need to verify frequencies and tones for license compliance.

The IP54 rating provides dust and splash protection, though not the full water resistance of IP66 models. It is a good compromise between durability and cost for most users.

7. LATNEX FC-3000P – Premium Portable Option

The LATNEX FC-3000P sits at the top of their portable frequency counter line with a 100MHz to 3GHz range. It features a rechargeable lithium battery, keypad lock to prevent accidental changes, and automatic squelch functionality. The 2-year warranty with phone and email support matches the FC-2800M.

For analog signal reading, it performs admirably. I tested with various VHF and UHF amateur radios, commercial LMR systems, and FRS walkie-talkies. The frequency readings were accurate and the signal strength indicator helped optimize positioning. The unit is lightweight at 113 grams and compact for pocket carry.

Unfortunately, the DMR performance is inconsistent. While advertised as compatible with digital modes, my testing showed unreliable results with DMR signals. Sometimes it would read correctly, other times it would fail to register or show incorrect frequencies. This is a significant limitation given the premium price over the SF401 Plus.

The 27MHz CB coverage is also problematic, similar to the FC-2800M. Despite marketing claims, it struggled to read CB frequencies accurately. If you need reliable CB measurement, this is not the right choice.

Best Applications for the FC-3000P

This counter excels for analog VHF/UHF work where you want the convenience of a rechargeable battery and keypad lock features. The 100MHz lower limit is actually an advantage for reducing interference from AM broadcast stations compared to counters that start at 27MHz.

The 2-year warranty and support access make this a good choice for users who value post-purchase support. However, if you need reliable digital mode reading, the Surecom SF401 Plus at a lower price is a better choice.

8. Delta DFC100 – Dedicated CB Counter

The Delta DFC100 is purpose-built for CB radio operators. Unlike the portable handheld counters, this is a benchtop unit designed to sit in your radio shack. The six-digit display is large and clear, showing frequencies with precision adequate for CB alignment work.

The inline mode is where this counter shines. You connect it between your CB radio and antenna using standard coaxial cables. When you key up, it displays your transmit frequency directly. I tested with several AM CB radios and found the readings accurate and stable. This is the most reliable way to verify your CB radio is on frequency.

The wireless mode allows you to hold the counter near a transmitting antenna without direct connection. However, my testing confirmed what other users report. The wireless mode is erratic and jumps frequencies unpredictably. Some units work better than others, suggesting quality control variations. I recommend using it primarily in inline mode.

The heavy construction feels solid and professional. This is not a pocket device. It sits nicely on a bench and stays put. The AC adapter provides continuous power without worrying about batteries.

Who Needs the DFC100?

This counter is specifically for CB radio enthusiasts who want accurate frequency verification for AM mode operation. The inline connection method provides the most reliable readings for CB alignment. It is not suitable for SSB operation, as the counter cannot properly read single sideband signals.

If you operate exclusively on 11-meter CB bands and want a dedicated benchtop solution, the DFC100 is a solid choice at $109. For multi-band ham use or digital modes, look at other options on this list.

9. Jieotwice TFC2700L – Lab-Grade Benchtop

The Jieotwice TFC2700L brings professional laboratory features to the hobbyist price range. The standout feature is the crystal heating oven, which maintains the time base crystal at a constant temperature for stability. This is a feature usually found on counters costing thousands of dollars.

I measured the warm-up time at approximately 15 minutes from a cold start to reach full stability. Once warmed up, accuracy was impressive. Testing against my GPSDO reference showed drift of less than 1Hz over several hours at 146MHz. The 20mV sensitivity allows measurement of weak oscillator signals that would be invisible to portable counters.

The eight-digit LED display is bright and shows frequencies with 1Hz resolution up to 2.7GHz. The cycle cumulative measurement mode lets you count events over time, useful for measuring slow signals or totalizing pulses. The self-test function helps verify proper operation.

The 4.4-pound weight and 9.75-inch width make this a substantial benchtop instrument. This is not portable equipment. It belongs on your workbench alongside your soldering station and power supply. The solid metal construction feels professional and durable.

Understanding the Calibration Limitation

One oddity is that the calibration adjustment screw is sealed with Loctite from the factory. You cannot adjust the calibration even if you wanted to. In practice, this is not a major issue because the unit arrives well-calibrated from the factory. However, it does prevent fine-tuning against an external reference if you are attempting ultimate accuracy.

For most ham and electronics work, the factory calibration is more than adequate. The stability from the crystal oven is more important than the ability to trim calibration for typical use cases.

10. Seeku 6GHz Counter – Professional Wide Range

The Seeku 6GHz frequency counter is the most capable unit on our list, extending coverage from 1Hz all the way to 6GHz. This covers not only all amateur bands but also WiFi, Bluetooth, cellular, and most commercial RF applications. The 11-digit resolution at 10MHz provides laboratory-grade precision.

The internal OCXO (Oven-Controlled Crystal Oscillator) reference is calibrated to within 1ppm from the factory. In my testing, accuracy was on par with professional counters costing five times more. The unit also accepts an external GPSDO reference for those seeking ultimate precision for frequency standard work.

The statistics display mode is particularly useful. It shows minimum, maximum, average, and standard deviation of frequency measurements over time. This helps assess signal stability, which is crucial for oscillator testing and calibration work. The built-in power meter function provides rough RF power readings, adding to the versatility.

Despite the professional features, the unit maintains a relatively compact footprint compared to traditional lab counters like the HP 53131A. It fits comfortably on a crowded workbench without dominating the space.

Who Should Invest in This Counter?

This counter is for serious RF enthusiasts, professional technicians, and anyone doing precision oscillator work. The 6GHz range covers modern communications systems including 5GHz WiFi and ISM band devices. The external reference input allows integration into a GPS-disciplined measurement system.

The main drawbacks are shipping time and limited reviews. This ships from China and takes 7-8 days to arrive. With only 5 Amazon reviews, there is less community feedback than established products. However, those reviews are uniformly positive, and my testing confirmed the high performance.

Frequency Counter Buying Guide for 2026

Choosing the right frequency counter depends on what you plan to measure, how accurate you need to be, and your budget. Here are the key factors to consider before making your purchase.

Frequency Range Coverage

Match the counter’s range to your intended use. For CB radio at 27MHz, any counter covering HF works. For 2-meter ham radio at 144MHz and 70-centimeter at 440MHz, you need VHF/UHF coverage. If you work with WiFi, microwave links, or modern LMR systems, look for coverage extending above 2GHz.

Most portable counters top out at 2.4GHz or 3GHz, which covers amateur bands and most commercial radio. The Seeku 6GHz counter extends this to cover WiFi and higher frequency applications. Benchtop units typically offer wider ranges with better sensitivity across all frequencies.

Time Base Accuracy and Stability

The time base is the heart of any frequency counter. Basic units use standard crystals with accuracy of 10-50ppm. This means at 146MHz, you could see errors of 1.5-7kHz. For identifying channels, this is fine. For precision alignment, it is inadequate.

TCXO (Temperature Compensated Crystal Oscillator) units like the Surecom SF401 Plus improve this to 1-5ppm. OCXO (Oven-Controlled Crystal Oscillator) units like the Seeku counter or Jieotwice TFC2700L maintain the crystal at constant temperature for stability of 0.01-1ppm. For ultimate accuracy, some counters accept an external GPSDO (GPS-Disciplined Oscillator) reference.

Input Sensitivity

Sensitivity determines the minimum signal level the counter can measure. Portable counters typically need strong signals from nearby transmitters. Benchtop units like the Jieotwice offer 20mV sensitivity, allowing measurement of weak oscillator outputs without amplification.

If you plan to measure crystal oscillators, PLL circuits, or other low-level signals, sensitivity matters greatly. For reading transmitter outputs, even low sensitivity works because transmitters produce strong signals. Check your specific application requirements.

CTCSS and DCS Tone Reading

Many repeaters and commercial systems use sub-audible tones for access control. CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital-Coded Squelch) are the most common. A counter that decodes these tones saves you from trial-and-error programming.

All the portable counters in our list from the ASHATA up include tone decoding. Quality varies. The Surecom units decode reliably while some budget models are slower or less accurate. If repeater access is important, this feature is essential.

Digital Mode Compatibility

Modern radios use digital modes including DMR, D-STAR, System Fusion (C4FM), and P25. Not all counters can read these signals. The Surecom SF401 Plus and ANYSECU SF-103 specifically advertise DMR compatibility and perform well in testing.

Analog-only counters may show erratic readings or fail entirely when presented with digital signals. If you work with digital modes, verify the counter specifically supports them. This capability adds cost but is necessary for modern radio work.

Portability vs Benchtop Operation

Handheld counters run on batteries and fit in your pocket. They are ideal for field work, identifying unknown frequencies at events, and travel. However, they require proximity to transmitters and lack the sensitivity and accuracy of benchtop units.

Benchtop counters offer better accuracy, higher sensitivity, and continuous AC power operation. They are the right choice for lab work, alignment procedures, and serious measurement tasks. Some, like the Delta DFC100, work in both modes with wireless and inline connection options.
