The Hallicrafters SX-28 RF2 Coil (Part Number 119) is a meticulously crafted, high-performance accessory designed to elevate the listening experience for dedicated shortwave radio enthusiasts and DXers operating with the legendary Hallicrafters SX-28 receiver. This coil, part of the RF2 series, is engineered to deliver exceptional selectivity and sensitivity across the 10-meter band, making it an indispensable tool for those seeking to unlock the full potential of this iconic transceiver. Constructed with precision and durability in mind, the coil features a robust, high-quality winding of fine copper wire, meticulously tuned to optimize signal clarity and minimize interference. Its compact yet sturdy design ensures seamless integration with the SX-28 s front-panel tuning mechanism, allowing operators to fine-tune their reception with unparalleled precision. The RF2 series is renowned for its superior performance in challenging propagation conditions, offering enhanced signal-to-noise ratios and reduced adjacent-channel interference, which is particularly valuable during periods of weak or marginal signals. Whether you're chasing distant international broadcasters, monitoring amateur radio contacts, or exploring the nuances of shortwave listening, this coil provides the refined tuning control necessary to isolate weak signals with remarkable clarity. Ideal for both seasoned DXers and newcomers looking to expand their listening horizons, the Hallicrafters SX-28 RF2 Coil (Part Number 119) embodies the brand s commitment to excellence in radio communication technology, ensuring a listening experience that is both immersive and rewarding.

The Hallicrafters SX-28 RF2 coil (part number 119, T14) is a popular addition for the classic Hallicrafters SX-28 receiver, a well-regarded general-coverage shortwave radio from the mid-20th century. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the Hallicrafters SX-28 RF2 Coil (T14, P/N 119)**

1. **Enhanced Frequency Coverage**

The RF2 coil extends the receiver s range into the lower shortwave bands, particularly around the 14 MHz region. This is useful for weak-signal DXing (long-distance reception) and amateur radio operations in the 20-meter band (14.000 14.350 MHz). The SX-28 s stock coils are limited in sensitivity and selectivity for these frequencies, making the RF2 coil a valuable upgrade for listeners targeting this range.

2. **Improved Sensitivity**

The RF2 coil is designed to provide better signal-to-noise ratio in the lower shortwave bands compared to the stock coils. This can make weak signals more audible, especially in areas with marginal propagation or during nighttime DX conditions.

3. **Compatibility with the SX-28**

As an original Hallicrafters accessory, the RF2 coil is mechanically and electrically compatible with the SX-28 s tuning mechanism and front panel. It fits seamlessly into the receiver s existing coil system without requiring major modifications.

4. **Historical and Collectible Value**

The SX-28 is a highly sought-after vintage radio, and its accessories, including the RF2 coil, hold value among collectors. Owning this coil may appeal to enthusiasts who appreciate the radio s heritage and authenticity.

5. **Versatility for Shortwave Listening**

The SX-28 is already a capable general-coverage receiver, but the RF2 coil allows it to excel in the lower shortwave bands where many international broadcasters and amateur radio stations operate. This makes it a practical choice for listeners interested in these frequencies.

6. **Durability and Reliability**

Hallicrafters components from this era are generally robust. The RF2 coil, being a passive RF component, is unlikely to fail prematurely if handled carefully. Many examples of this coil still function well after decades of use.

7. **Ease of Installation**

Swapping coils on the SX-28 is a straightforward process that requires minimal tools. The RF2 coil can be installed in a few minutes without voiding any warranties or requiring professional assistance.

### **Cons of the Hallicrafters SX-28 RF2 Coil (T14, P/N 119)**

1. **Limited Frequency Range**

While the RF2 coil improves reception in the 14 MHz region, it does not cover the entire shortwave spectrum. The SX-28 s stock coils still provide better coverage for higher frequencies (e.g., 21 30 MHz). If you need a single coil to cover all shortwave bands, this may not be sufficient.

2. **Potential for Weak Signals at Other Frequencies**

Using the RF2 coil exclusively may result in reduced sensitivity or selectivity on frequencies outside its designed range (primarily 14 MHz). For example, reception of signals above 20 MHz might suffer compared to using the stock coils.

3. **Aging Components**

Like all vintage electronics, the RF2 coil may show signs of wear over time, such as degraded solder joints, oxidized terminals, or weakened coil windings. While this is rare, it is a possibility, and the coil may require occasional maintenance or cleaning.

4. **No Built-in Band-Switching**

The SX-28 s coil system requires manual switching between coils. If you frequently listen across a wide range of frequencies, you ll need to switch coils often, which can be inconvenient. Some modern receivers offer automatic band-switching, which this coil does not provide.

5. **Potential for Interference**

The SX-28 is known to suffer from image interference and poor selectivity on some frequencies, even with the RF2 coil. This is inherent to the receiver s design and not solely the fault of the coil. Expect some trial and error when tuning, especially in crowded bands.

6. **Cost Relative to Modern Alternatives**

While the RF2 coil is not expensive (typically under $100 new or used), modern general-coverage receivers (e.g., the IC-7300, Elecraft K3, or even budget options like the SDRPlay RSP1A) offer superior performance, digital tuning, and broader frequency coverage for a similar or lower price. For serious DXers or ham radio operators, a modern rig may be more practical.

7. **Maintenance Requirements**

The SX-28 itself requires periodic maintenance, such as cleaning the tuning capacitor, checking the power supply, and ensuring the coil system is free of dust or corrosion. Neglecting these tasks can degrade performance, regardless of the coil used.

### **Conclusion**

The Hallicrafters SX-28 RF2 coil (T14, P/N 119) is a worthwhile addition for owners of the SX-28 who are specifically interested in improving reception in the 14 MHz region. It offers enhanced sensitivity and selectivity for this band, making it a practical choice for shortwave listeners, amateur radio operators, and collectors who appreciate the vintage aesthetic and functionality of the SX-28. However, it is not a universal solution for all shortwave frequencies and may require manual coil switching for optimal performance across the entire spectrum.

For listeners who primarily target the lower shortwave bands (e.g., 14 MHz) and enjoy the charm of a classic radio, the RF2 coil is a solid upgrade. For those seeking broader frequency coverage, better selectivity, or modern conveniences like digital tuning, a contemporary general-coverage receiver may be a more versatile long-term investment.

### **Recommendation**

- **Buy the RF2 coil if:**

- You already own an SX-28 and want to enhance its performance in the 14 MHz band.

- You are a collector or enthusiast who values the historical significance of the SX-28 and its accessories.

- You primarily listen to signals in the 14 MHz range (e.g., amateur radio, international broadcasters on 20 meters) and are willing to manually switch coils for other frequencies.

- You are on a budget and prefer a vintage, analog solution over modern digital receivers.

- **Avoid or consider alternatives if:**

- You need a receiver that covers a wide range of frequencies with minimal coil switching. In this case, a modern general-coverage receiver (e.g., the IC-7300, Elecraft K3, or even a budget SDR like the Perseus or SDRPlay) would be more practical.

- You prioritize selectivity and image rejection over vintage aesthetics. The SX-28 s stock coils and RF2 coil are not as selective as modern superheterodyne or SDR receivers.

- You are open to upgrading the entire SX-28 with modern components (e.g., a new power supply, improved tuning capacitor, or external preamplifier) to enhance its overall performance.

Ultimately, the RF2 coil is a niche but valuable accessory for SX-28 enthusiasts. If you are committed to the SX-28 platform and its limitations, it is a reasonable purchase. However, if you are evaluating the coil as part of a broader decision about whether to invest in the SX-28 or modern alternatives, weigh the trade-offs carefully.
