The Italian Navy was noted to use wireless during manœuvres in 1906, as they were intercepted by the British.[1]

The use appears experimental and immature, with messages being nearly all en clair and using commercial procedural signs of "O K" and "T S T". It was further noted that "R D" was used in place of the British phrase "R R R".

Signalling was on wavelengths of 500, 1,200 and 2,500 feet and at speeds of 15 to 20 words per minute.
