Dee ^8 Qpmposltlon of ArmyFrequency List 1. This memorandum is intended to provide guidance on the method of preparing the Army frequency list and on tho seal© of frequencies to be provided. 2. There are four main classes of frequency requirenent to be covered: a. Frequencies for fixed radio links employing high power static sets; b» Frequencies for emergency and mobile extensions of CASS employing AN/GRC~26 sets; Co Frequencies for training and for survival operations employing mobile field-»typa sets; a. Frequencies for low power THF flaid sets and for radio relay or keying links# UXJ&JADIO J-INKS 3o Frequencies must be cleared and internstianally ragister od to provide for fixed radio links covering 24 hour operation over the full solar cycle• Suitable frequency complements for each circuit for 24 hour operation through a complete solar cycle will be the long-term aim. The scale of circuits is indicated in the attached wireless diagrams (Annexes 1-6 Inclusive), ,4. These frequencies must be cleared for J5A1F1 operations to appropriate power and every effort will be made to use those frequencies on which the Army already has a useful international registretloa status. po It is important to establish for each of these fraquen« cies a complete usage and interference history*. Furthermore;, Signals 30 aust bear in mind the need for frequent use of these frequencies even when they are not normally required by virtue of circuits not operating on a 24~hour basis; if frequencies are not periodically put into use, they will be taken up by other agencies and thus will lose" their value to the Army* 6S It is also important to ensure that new assignments by other countries or agencies are carefully and promptly checked against our use. Failure to record our position on such nev/ assignments may result in loss or deterioration of our own rights and registration status0 % Tha requirements of Signals 2 must be covered by Signals 3c in the same manner as the CASS circuit requirements. 8. In the frequency list to be published by the directorate, frequencies for these fixed radio links will be described by the symbol C A S S / K C . �i." 3 rr-,V ... j*^..",.- a ' , IT *,-»•'.,,• Document disclosed under the Access to Information Act " " " I ' ' Document divulgue en vertu de la Loi sur I'acces a (informat CASS gK-MSIOM LINKS 9® Each Command and No 1 Army Signal Squadron has (or will have) four or six AN/GE,C«26 stations. 10.

It is therefore proposed that an attempt be made to clear two frequencies only in each of th© seven bands for each Command* 14 0 Xr, the frequency M s t to be published by' the directorate,, frequencies for these GaSS extension TJ.nks will be described by the symbol CASS/XTNC 15. Eech Command has a requirement for frequencies for low* power mobile sets of the Type 19"and 29 set* / These "sets aro used for training and exercises, and during survival operations'would be used in mobile columns assisting Civil Defence„ 16 6 In addition certain Commands have recurring requirements for additional frequencies for concentrations and major exercises (eg Wainwrlght5 Petawawa and Gagetown) over and above their normal training and survival operation frequenciess IT 000116 �T Document disclosed under the Access to Information Act Document divulgue en vertu de la Loisur I'acces a (information 17• It is Intended to provide a list of, say, 20 frequencies for normal training and survival operations, and a further list of 20 for the concentrations andr-speclal exeroises. The first group of 20 should be reasonably free of conflict so that they can be used regularly for training. The seoond list of 20 frequencies should be as free* of conflict as possible but may be of a lower order of quality since they will be used less frequently. In each list of 20 frequencies, five should be for 300 watt operation and tha remainder for 25 watts. If more than this quantity is available or has been shown as needed in the past, the size of these lists siaould be accordingly increased. These-frequencies will probably have to be on a non-interference basis in many cases. 180 Frequencies for training and survival operations etc will be described by the symbol TRG. Frequencies for VHF Sets, Radio Relay and Keying Links 19o Arrangements should be made for the use of frequencies in the 20-70 Mo/s band for "VHF field type sets for trainings exercises, and survival operations. As many conflict-free frequencies as possible should be provided* Some must be capable of use in urban areas (at least 30-40 frequencies per Cocmiand if possible) and some in addition should be added for use in major training areas. These will presumably be on a non-interference basis under DOT conditions« 20. Frequencies must be provided for any radio relay sets to be supplied to field units (eg B70); the numbers to be provided will depend on the number of sets likely to be issued and Signals 4 advice on this should be obtained. Frequencies for Signals 3 planned radio relay will ultimately be required; plans for these are not yet firm. Frequencies already supplied for existing radio relay or keying links must be verified as to status and usability3 and included« (W H Finch) Lt Col Sigs 3 P 000117 �_ .... ...
