HC Deb 21 December 1925 vol 189 c1944
44. Brigadier-General MAKINS

asked the President of the Board of Trade whether, seeing that while British ships suspend wireless communication for three minutes every half-hour to listen to distress calls according to Appendix X, Handbook for Wireless Telegraph Operators, whereas foreign ships do not do so, and in addition use these periods to push through their messages, thus interfering with the S.O.S. calls, he will endeavour to reach some international agreement on the question to avoid such confusion?

The ASSISTANT POSTMASTER-GENERAL (Viscount Wolmer)

I have been asked to reply Endeavours will be made at the next International Radiotelegraph Conference to reach an agreement on this question.
