The commitment of 21 circuits to "HYDRA" theoretically reduces the growth capacity available to EASE, but in fact such an expansion would be unlikely to be approved solely for EASE and would not bo possible in time of emergency, The propos; increases the maintenance load and supervisory commitment but this is consid; to be within the capability of the araergency staff, CONCLUSION 20, The relocation of the HYDRA telegraph relay cent would provide in peacetime all possible assura communications in an emergency. �•••«p •"•! «gpi 0 P Y Document divulgue en vertu de la Loi sur faeces a {'information Foreign Office. S.V.I, January 25, 19o2 Dear John, I • to have replied before this to your letter of Decern ;.ch you asked me about our plans for the use of the Hydra communications system In wartime, 2, I undi nd that British users, of whom the main ones are, as you say, the Embassy in Washington, the Delegation to the U.S. in Hew York and the High Commission in Canada in communication with Government Departments in Whitehall, account for about 31$ of the traffic carried over the system in peacetime. No doubt in wartime the system would be available for use by any of the surviving members. V.'e should certainly hope to use it for communication from the Foreign Office to our Foreign Service posts in '.'.ashington and New York, for example, and arrangements will be made on the U.K. side for the U.Ka terminal at the syst to be transferred at the appropriate time to the site of the emergency Government HQ in war. I cannot at this stage say whether the Americans are similarly planning to transfer the Hydra terminal in the U.S. to their wartime site.. This Is a subject on which you may have more Information than ourselves? 3. I imagine that It would also be reasonable to expect Hydra to provide limited facilities for the Canadian, British and U.S. authorities generally if other means of trans-Atlantic communication failed* I am afraid we cannot estimate what the volume of traffic is likely to be, but it would undoubtedly be heavy. 4C If you agree. I think there is one precaution we should take now to ensure that your Hydra terminal remains in touch with Foreign Service and C.R.O. posts in wartime. The DTS have issued crystals for two common frequencies to all their stations at Foreign Service and C.R.O. posts, so that, radio conditions perrail .. there can be intercommunication between them even in the event of the complete elimination of DV:S stations in the U.K. If your radio station is given similar crystals with appropriate instructions, it will be able in wartime to call any DY'S station which radio conditions might bring within range, This facility would be roost valuable for us and also, I think, useful to you for tha transmission of your telegram through our posts to Canadian reoresentatives. As soon as I have your agreement to this, the DWS will make the necessary arrangements, 5. I am sending a copy of your letter and my reply to Vhlker In the CRO in c 3 wishes to add anything. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
