Rx:158.160 MHz PL=4A. b.Presently,HEA (Homer Electric Association)operates a VHF solar powered repeater at the AEA Eagle Lake Site.This repeater presently operates on: Tx:153.560 Hz PL=2A,4A. Rx:158.160 MHz PL=2A,4A. Upon installation of the new AEA Operations Repeater at the Eagle Lake Site,the existing HEA unit will be removed and returned to HEA. c.The new AEA Operations Repeater will be used by AEA,HEA,and CEA(Chugach Electric Association).This repeater will be used by AEA for continuouseverydayoperationsanddatatransfer.This repeater will also be used by HEA andCEAwhenperformingassociatedoperationsandmaintenancefunctions. 2.AEA Powerhouse: a.AEA will purchase a VHF repeater for their powerhouse location at Bradley Lake. The VHF repeater will operate on the following frequency: Tx:153.710 MHz PL=3A.
