- Radio Control for Yachts – Part Two
- Super-regenerative Receivers: simple but prone to interference; only one boat can operate at a time.
- Superheterodyne Receivers: more expensive but allows multiple boats (up to 16) to sail simultaneously.
- Crystal-controlled oscillator for stability. Intermediate frequency stages for selectivity. Direct-coupled output for steady voltage.
- Tested up to 650 yards with perfect control.
- Championship Regattas – Declining Entries
- Significant drop in entries for national championships (A-Class down to 22 from 40+).
