24. way is to use EchoLink s built in VOX voice operated switch The VOX monitors incoming audio from the receiver When properly adjusted the VOX will trigger only when a station is being heard over the receiver One advantage of using VOX is that no other connections between the receiver and the PC are required VOX is particularly useful when EchoLink is connected to a transceiver that is monitoring the output frequency of a repeater The VOX will trigger only when a station is actually speaking through the repeater and will not generally respond to the repeater s tail which could be as long as 10 seconds after each transmission However VOX is not completely reliable since it is unable to detect a dead carrier Also it introduces an additional delay of a second or so after each transmission To help circumvent these issues EchoLink also supports a direct connection between the receiver and the computer s serial port for positive carrier detect This type of connection is especially useful for simplex links EchoLink User s Guide Many transceivers have a back panel connection called busy or carrier detect that tracks the squelch circuit directly This can be wired to the CD DSR or CTS pin of the PC s serial port and EchoLink can be configured to respond to it instead of using VOX Typically this connection must be made through a simple interface such as a one transistor circuit The circuit should drive the CD DSR or CTS pin

33. Remote or Hard Wired There are two ways a repeater can be connected to EchoLink With the hard wired approach the PC on which EchoLink runs is co located with the repeater controller and interfaced directly to it with no additional RF hardware This allows positive carrier and PTT control between the repeater controller and EchoLink and eliminates extra hops in the audio chain It also eliminates the need to ID a link transmitter One disadvantage of this technique however is that it requires reliable Internet access at the repeater site which may be in a remote location With the remote link approach an FM transceiver is connected to the EchoLink PC at a convenient location in range of the repeater and tuned to the frequency pair of the repeater In this configuration the transceiver behaves very much like an ordinary local repeater user transmitting on the repeater s input frequency on behalf of EchoLink users and receiving on the repeater s output frequency Although this allows the EchoLink equipment to be placed in a more convenient location it presents some challenges with respect to RX control With either approach EchoLink should be configured with a callsign with a R suffix to indicate that the node is a gateway to a repeater rather than a simplex frequency If a remote link is being used the software should be configured to identify itself on the air with the host station s callsign which is not necessarily the sa
