The AS2x2 is a 2×2 antenna switch designed to be used by 2 Radios and where they can share their antennas. A typical application could be a contest station where there are 2 radios in the same band (RUN and InBand). By default the RUN uses the main antenna and the InBand uses a far away reception antenna.

When the Inband need to make a QSO, the AS2x2 will exchange the antennas, so the InBand will use the main antenna meanwhile the RUN will use the reception antenna, so they can still listen their QRG.

If a linear amplifier is used by the RUN, the Inband can also use it for his transmission. In this case, the AS2x2 is connected between the RUN and the Linea Amplifier.

  • AS2x2

    The antenna Switch AS2x2 is a 2 Input Ports into 2 Outputs Ports, usefull for a contest station where you have a Main Radio (RUN) and a Multiplier Station (Inband) at the same band. In this way, the RUN station uses the main antenna(s) while the Inband station is looking for new multipliers or QSOs and uses an RX antenna located far from the main antenna. As soon as the Inband station passes to TX, the switch AS2x2 inverts the antennas, passing the Inband station to use the Main antenna while the RUN does not run out of antenna put to use the antenna of RX.

    The AS2x2 can be connected between the RUN Radio and the Linear Amplifier (in case a Amplifier is used) and between the Inband Radio and the RX antenna. As soon as the Inband Radio activates the PTT the AS2x2 will exchange the outputs, so the Inband will use the Linear Amplifier and the RX antenna will be assigned into the RUN Radio.

    The AS2x2 can be used combined with the Interlock 5R so in this case, the Interlock 5R will control automatically the antenna switching.

As an option to the Interlock we have just added the AuxBox

Any any equipment that don’t incloude an Inhibit signal can use this box for the microphone and cw interconexion.

So the Mic and CW connectors are conneted to this new box and from the box to your Radio. When the Inhibit is activated by the Interlock 5R, the signal will activate the relays inside the AuxBox so the radio will not transmit.

We are pleased to announce a new product: EA4TX INTERLOCK. The Interlock device ensures the compliance with Radio Contest rules for the participation in Multi-Operator categories as M/S, M/2 and when Inbands Radios are used. Since Nov/2012 when we designed the first unit for ED1R we have improved and increased features and performance. This video was done by EC1KR at ED1R on 2012/Nov (spanish)
