There will be a sufficient number of stations reoLired by the V.eapons Effects Tests projects in futvire operations to warrant a separate channel for their use^ 3. V-K- activation of this facility would: a, Elininate overcrowding of ercisting nets. bo Eliminate the re-^uirer.ent for same of the high frei.-ucncy channels that have been recuestod by -a^ojects of the .eapons Effects c. Leave remaining nets free for other agencies for their oarticular use in caue of fin «merr«ncy, indcpendeit channel to control the activities of military effects 4. Based on inlormation presently available, i t appears that there will be a re-'tdrement for approxliiately twenty-five (25) stations for M'eaT>ons Effects Tests activities during the tests to be c inducted next spring, 5.
