Review MFJ Cw Filter Tech

The CWF-2 MFJ CW Filter is a high-quality, compact, and versatile product designed to improve the clarity and efficiency of Morse code transmissions. This filter, manufactured by MFJ Enterprises, is an essential tool for any serious amateur radio operator.

The CWF-2 is a 2-pole, 3-kHz bandpass filter, specifically designed for Morse code communications on the HF bands. It features a center frequency adjustment range of 1.8 to 30 MHz, allowing it to be used on various HF bands, including 160 meters, 80 meters, 40 meters, 30 meters, 20 meters, 17 meters, 15 meters, 12 meters, 10 meters, and 6 meters.

The filter's construction is robust and reliable, with an aluminum chassis and high-quality components, ensuring long-term durability and performance. It has a compact size, measuring only 4.5 inches (11.4 cm) long and 2.25 inches (5.7 cm) wide, making it easy to install in even the smallest radio stations.

The CWF-2 MFJ CW Filter offers a 3 dB bandwidth of 1.5 kHz, ensuring that only the desired Morse code signals are passed through, significantly reducing interference and improving the quality of the transmitted and received signals. It also features a bypass switch, allowing quick and easy switching between the filtered and unfiltered signals, making it easy to monitor the effect of the filter without having to disconnect it from the radio.

In addition, the filter has a low insertion loss of less than 0.5 dB, ensuring that it does not significantly degrade the signal strength. It also has a high Q-factor, which means it has a narrow bandwidth and can effectively reject unwanted signals, further improving the signal-to-noise ratio of the received signals.

The CWF-2 MFJ CW Filter is easy to install and use, with clear and easy-to-read markings on the adjustment knobs and a user-friendly design. It is powered by a 12V DC power supply, which is not included in the package, and it features a standard BNC connector for easy connection to the radio.

In summary, the CWF-2 MFJ CW Filter is a high-quality, compact, and versatile filter designed to improve the clarity and efficiency of Morse code transmissions on the HF bands. Its robust construction, adjustable center frequency, and low insertion loss make it an essential tool for any serious amateur radio operator. Its compact size, user-friendly design, and ease of installation make it a great choice for both new and experienced operators.

Pros of buying a CW-2 MFJ CW Filter:

1. Improves signal clarity: The filter helps to eliminate unwanted noise and interference, thereby improving the signal clarity for CW (Morse code) communication.

2. Reduces QRM (Quiest Routine Modulation): The filter reduces the amount of QRM, which is the noise caused by other operators transmitting, allowing for better reception.

3. Easy to install: The filter is easy to install and requires no modifications to the existing setup.

4. Compact design: The filter has a compact design, making it easy to fit into any radio setup.

Cons of buying a CW-2 MFJ CW Filter:

1. Limited frequency range: The filter is designed for a specific frequency range and may not work effectively for all CW frequencies.

2. Additional cost: The filter is an additional cost to the radio setup and may not be necessary for all operators.

3. May require tuning: The filter may require tuning to work effectively, which may require some adjustments and experimentation.

Conclusion:

The CW-2 MFJ CW Filter is a useful tool for CW operators who are looking to improve their signal clarity and reduce QRM. However, it is important to consider the limited frequency range and additional cost before making a purchase. If the filter is within your budget and meets your frequency requirements, then it is a worthwhile investment.

Recommendation:

If you are a CW operator and are looking to improve your signal clarity and reduce QRM, then the CW-2 MFJ CW Filter is a good option to consider. However, it is important to do your research and determine if it is the right fit for your specific radio setup and frequency requirements.

Details:

Unfortunately, it is not working. Sold as-is for parts or repair.

Shipping: no overseas shipping.

Unfortunately with my schedule I simply do not have time to handle them.

Sorry, no pickups. Unless noted, listing includes only what is shown.

Smaller packages are usually shipped via the USPS. Here is a Mfj CWF-2 cw filter.

Otherwise, there is no signature requirement. However, if that arrangement also causes problems, then I cannot help since can not wave this requirement.

I will do my utmost to resolve any issues. Both FedEx and the USPS will hold a parcel at their local office for you to pickup your convenience if someone cannot be available during day when is delivered. Just attenuates the signal.
