The AOR AR-8600Mk2 is the latest mobile/base station to emerge from the AOR factory and has been enhanced in several areas. The upper frequency range has been extended to 3000MHz (3GHz), lower band sensitivity has been increased (now covering down to 100kHz). Extra enhancements to SW performance by the addition of further band pass filters and a selection of alternative IF filters. Mini-Circuits RMS1 / RMS2 mixers have been employed with active SPM antenna switching devices (not diode-switching). The AR-8600Mk2 will accept slot cards, with all five cards fitted at once if required. For Air band enthusiasts the receiver includes 8.33kHz channel steps correctly supported eight-and-one- third, 33, 66, 00. An RS232 port is provided for PC access and a wideband 10.7MHz output is provided for use with the SDU5500 spectrum display unit. The receiver will be shipped with a telescopic whip antenna, MW bar aerial, DC lead and operating manual. All optional products for the AR-8600 are compatible with the Mk-2 version.
