ACOM 2S1 | Automatic XCVR Commutator

Description

Usage
The ACOM 2S1 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 simultaneous reception.

Automatic operation
Operation is fully automatic and the full break-in (QSK) mode in CW is standard.

Easy to use
The ACOM 2S1 may be used to commutate an antenna only or can be adapted in other systems, too. ACOM 2S1 is especially designed to complete the ACOM 2000S automatic antenna selector and ACOM 2000SW remote antenna switch, and the ACOM 2000A automatic HF linear amplifier.

Integrated power supply
There is no need of external power supply device. The ACOM 2S1 uses power supply directly from the transceiver (11-14 VDC / 30 mA power supply).
