HC Deb 20 April 1926 vol 194 c1018
44. Sir H. BRITTAIN

asked the Postmaster-General whether, following the recent successful trans-Atlantic telephonic communications, any further developments are taking place; and, if so, whether he is able to give the House any further particulars?

Sir W, MITCHELL-THOMSON

I am not in a position to give the House any further information in regard to these tests at present. Experiments continue to be conducted with a view to solving the numerous technical difficulties involved in simultaneous two-way radio-telephone transmission, where land telephone lines must be associated with the radio link at both the transmitting and receiving ends.
