Part 2/6:
As he examines the sonar equipment, he mentions its compatibility with an R390A, a model he possesses multiple versions of. This compatibility suggests a remarkable interconnectivity within naval technologies of the era. The narrator highlights specific features such as video input, excitation signals, and an azimuth indicator, increasing the unit's technical allure.
The equipment's detailed workings are described, including its role as a combination oscilloscope monitoring system paired with a mechanical oscillator for frequency generation—a rather unusual setup for sonar technology.
