CQ, Aug 1961, p. 120. QST, Sep 1961, p. 132. QST, Oct 1962, p. 139. QST, Jul 1963, p. 142. QST, Jan 1964, p. 144. QST, Apr 1965 p. 140. The AR-1 transfers the antenna to the transceiver while receiving and provides the necessary switching to connect the exciter to the amplifier, and the amplifier to the antenna when transmitting. A front panel switch also permits the exciter to operate straight through to the antenna. The relay is shock-mounted and the case is insulated to reduce noise. Standard SO239 connectors are provided for low impedance coax lines. Insertion loss: Transceiver output to amplifier input, less than 1.02:1 SWR, 3 to 30 MHz. Amplifier output to antenna, less than 1.12:1 SWR, 3 to 30 MHz. Requires 6.3 VAC (6.3V jack on KWM-2) and normally open auxiliary contacts on the exciter relay. (ANT. RELAY jack on KWM-2). The AR-1 may also be used as a conventional antenna change-over relay.
