Emergency Control Facilities Canadian Army Signal System Hydra System 1. Progress report on OWS Project E-21-0 with reference to your HQs 1269-1 (D Sigs) dated 30 July 1957 and HQs 1269-1 dated 17 July 1958. 2. The Emergency Keying Link O W S / O R L / O S H is being keyed periodically as instructed and recently test v/ere conducted over a 2h hour period for seven days to determine the overall availability of the link. Results of this test were satisfactory, however, the use of proper frequencies, antennae arrangements at Oshawa, and the use of DES equipment would improve this link considerably. 3. During this test the Emergency Keying Link was extended through to the United Kingdom on a regular transmitter as would be the case in an Emergency, and the reported reception in UK for a two hour period was 100$. h. Single frequency shift keying *jas used throughout this test in place of amplitude modulated transmission, as previous tests on this link show frequency shift keying to be m'ore reliable. 5. To further improve the Emergency Keying system on Hydra may the following be given your consideration: (a) The allotment of two frequencies in the 7 megacycle band, one for use to Oshawa from Orleans, and one for use from Oshawa to Orleans. (b) The installation at Oshawa of suitable receiving and transmitting antennae to accomodate frequencies in use on this link. (c) The installation of DES shifter on transmitter at Orleans and DES convertor for reception at Oshawa, which will provide one engineering channel and one traffic channel. (d) It is suggested that if the link is double frequency shift operated, one channel could become a permanent radio engineering circuit, security permitting, as the use of this circuit for engineering on a 2U hour basis would ensure constant availability of the traffic channel in an emergency. 6. On request of Capt Chisholm, Sigs 3C, we have been using VEE as call sign on test tape v/hen testing Orleans to Oshawa, and^ have been advised that we will be notified of call sign to use when testing from Orleans through Oshawa to the United Kingdom.
