The ACOM2S1 is a TX/RX commutator that allows two transceivers to use a common load.
It guards each transceiver’s input while the other transceiver transmits, prevents simultaneous transmission, and allows
ACOM2S1 is especially designed to complete the ACOM2000S/SW automatic antenna selector (plus ACOM2000SW remote antenna switch) and the ACOM2000A automatic HF linear amplifier.
Nevertheless, it may be used to commutate an antenna only, or can be adapted in other systems, too. Operation is fully automatic and the full break-in (QSK) mode is standard.
