ACOM 2S1 switch for two transceivers
Automatic TX/RX switch for two transceivers on a common load, 1.8–54 MHz, 200 W, QSK
The ACOM 2S1 is an automatic TX/RX switch that lets two transceivers use a common load: it protects the input of one while the other is transmitting, prevents simultaneous transmission and allows simultaneous reception.
Product description
It was designed to complement the ACOM 2000S/SW automatic antenna selector (with the ACOM 2000SW remote switch) and the ACOM 2000A automatic amplifier, but it also fits other systems, not just antenna switching.
Operation is fully automatic and full break-in (QSK) is standard. The T/R sequence and RF relay contacts are monitored continuously; the input of the idle transceiver is grounded while the other one transmits.
Key features
Simultaneous reception, exclusive transmission.
Input grounded while the other transmits.
Full break-in as standard.
