Some pertinent GBTT trivia.
1) We had, in the Radio Room, a home made morse GBTT sender made by Jim Neary it was a motorised bakelite wheel with a microswitch on it, you could summon it from any of the radio bays and we used it to send a Tone --. -... - - in morse when raising WOO or WOM for phone calls to USA, it was instantly heard by Greg and the good guys at WOO ocean Gate Radio. - It would have been cheeky to try that with Portishead.
2) A certain un-named Chief R/O once called Portishead saying 'Portishead Radio, Golf Travo Bango Bango'
3) The 1 and 2 lifeboats had Callsigns GBTT22 and GBTT33
4) Portishead used to call us either 'Great Britains Terrific Traveller' or 'Great Big Tasty T*****s' depending who was on watch.
5) The Vibroplex company, american morse key manufacturers donated 2 semi-automatic morse keys to the Radio Room. These were used extensively by Phil Marriott and Brian Martin, but the rest of us preferred an old fashioned proper key!! (All proper key is theft)
6) On the subject of Morse we once sent the ENTIRE passenger list with names DOB Passport Number and nationality to a chinese coast station in the days before telex. It took over 5 hours and is believed to be the biggest telegram ever sent, we took it in turns 1/2 hr at a time.
When we got to the port the agent said it would have been ok to hand over a printed list on arrival instead.
7) Finally GBTT was, and remains, the most famous callsign in maritime history.
Willum
