Step 3
- The screw holding the antenna in place may have fallen out, and would be loose in the device or stuck to a speaker magnet. Re-secure the screw if it was loose.
- Inspect the solder joints that join the coaxial cable to the antenna. If the coaxial cable solder joints are loose, frayed, or snapped, re-soldering is required.
- If the solder joints are damaged, desolder the coaxial cable from the antenna base.
- Soldering irons can reach temperatures of up to 900 degrees F. Handle with caution.
- Carefully solder the antenna signal element to the small wire in the core of the coaxial cable. Ensure the core wire can not touch any other electrical connections.
- Gently arrange the coaxial cable so that the outer shielding of the coaxial cable can be soldered to the ground of the antenna. Check that the solder joint is sturdy.

Thank You for that information, Martin. I’ve been scratching my head as to how to dismantle one of these radios, despite having been in the repair trade for over 40 years.
