In this video, I take a deep dive into the legendary AN/PRC-74, considered one of the first true HF manpack radios. Its compact and portable form factor set the standard for many military radios that followed.
I purchased this unit as untested, with no guarantee it would even power on. After careful work, troubleshooting, and a few key modifications.
Currently, the radio operates in USB (Upper Sideband) only, which is one of its main limitations. In the future, I may explore modifying it to support LSB (Lower Sideband) as well.
👉 Stay tuned to the channel if you’re interested in similar restorations and radio projects.

💬 And if you’re familiar with the AN/PRC-74, I’d love to hear from you:
What common issues have you encountered?
What modifications or improvements would you recommend to keep it running longer?
Let me know in the comments!
