slash or stroke good to know

Yo ham radio operators and SWL enthusiasts out there.
 When transmitting in a visited country the licence holder must use his national call sign preceded by the call sign prefix of the visited country. The call sign prefix and the national call sign must be separated by the character "/" in CW or the word "stroke" (phone).

    So if I (EA6VY) was visitting Australia, my callsign would be VK/EA6VY (Victor Kilo "Stroke" Echo Alfa 6 Victor Yankee)!!

For a mobile amateur radio station the national call sign must be followed by the characters
"/M" (telegraphy) or the word "mobile" (telephony). For a portable amateur radio station the national call sign must be followed by the characters "/P" (telegraphy) or the word "portable" (telephony)."
