### Pros and Cons of buying a Watkins Johnson 8732A Military Radio Receiver (90 300 MHz, Ham/Amateur)

#### **Pros**

1. **High Performance and Reliability** The 8732A is a well-regarded military-grade receiver known for its durability and consistent performance. It was designed for harsh environments, making it suitable for field use, emergency communications, and amateur radio operations.

2. **Wide Frequency Range** Covers 90 300 MHz, which includes VHF amateur bands (144 148 MHz), aviation bands, and other public service frequencies. This versatility makes it useful for general ham radio, emergency communications, and scanning.

3. **Military-Grade Build** Constructed with rugged components, it is resistant to shock, vibration, and extreme temperatures, making it ideal for portable or field deployments.

4. **Good Sensitivity and Selectivity** While not as advanced as modern SDR receivers, it provides solid performance for its class, with adequate sensitivity for weak signals in clear conditions.

5. **Compatibility with Amateur Radio** Fully legal for ham radio use in most jurisdictions (with proper licensing), making it a practical choice for licensed operators.

6. **Modular and Upgradable** Some users have successfully upgraded or modified it for better performance, though this requires technical skill.

7. **Proven Longevity** Many units remain in service decades after production, indicating reliability over time.

#### **Cons**

1. **Outdated Technology** Compared to modern software-defined radios (SDRs) like the SDRplay or RTL-SDR, the 8732A lacks digital processing, limiting features like DSP filtering, waterfall displays, and digital modes (e.g., PSK, FT8).

2. **Limited Connectivity** No built-in USB or digital interfaces; it relies on analog outputs (headphones, speaker, or external audio interfaces), which can be inconvenient for modern setups.

3. **Manual Tuning and Operation** Requires physical knobs and dials, making it less user-friendly than digital radios with touchscreens or remote control options.

4. **No Built-in Memory Channels** Unlike modern radios, it lacks preset memory channels, requiring manual tuning for frequently used frequencies.

5. **Maintenance and Parts Availability** As a vintage military radio, finding replacement parts or servicing can be difficult, especially if the unit develops issues.

6. **No Built-in Antenna Tuner** Users must provide an external antenna tuner for optimal performance on certain bands, adding complexity.

7. **Limited Digital Features** Cannot decode digital modes, GPS time signals, or modern modulation schemes without external modifications.

---

### **Conclusion**

The Watkins Johnson 8732A is a robust, high-performance analog receiver ideal for enthusiasts who prioritize reliability, durability, and a wide frequency range without modern digital features. It excels in environments where ruggedness and simplicity are valued such as emergency communications, field operations, or vintage ham radio setups. However, for users seeking advanced digital capabilities, software-defined radio (SDR) solutions may be more practical.

### **Recommendation**

- **Buy if:** You need a durable, military-grade receiver for analog VHF communications, enjoy analog tuning, or are working within a budget that favors reliability over modern features.

- **Avoid if:** You require digital modes, SDR functionality, or a user-friendly interface. In that case, consider a modern SDR like the RTL-SDR, SDRplay RSP1A, or a digital ham radio such as the Yaesu FT-65R.

For most contemporary ham radio operators, a newer SDR or digital radio would be a better long-term investment, but the 8732A remains a strong choice for those who appreciate its classic design and rugged performance.

Details:

Therefore, this is being sold as. I mention it in the. Therefore it is untested. I confronted her on this, and she proceeded to tell me that could be sued if someone got hurt by plugging something in.

The joke is she was selling two antique radios that were AC/DC sets with hot chassis, but guess what didn cut the cords on them. If I list equipment as untested, it truly is. Being offered is a W.J. Now for the good stuff.

By selling under the for parts are not working statement, I am protected from scam artists who try to return items. My call is W3OWE and I am fairly well known throughout the military radio community. This unit has no power cord. If I listed describing as working, it truly is.

Receiver as shown. Yeah, you can't make this crap up.
