EchoLink 07

YoumightndthatyouareunabletogetenoughaudiolevelevenwiththeMicrophonelevelsettomaximum.Ifthat’sthe

case, the audio output level from TM‑D710 can be adjusted using the MCP‑2A (or MCP‑6A) software, downloadable from

the KENWOOD Support Web site. Once you have the MCP‑2A (or MCP‑6A) program up and running, go to the Data

Terminal Adjustment section, and increase the PR1 Output Level (EchoLink Mode) from 3 to a higher value such as 6 or 7.

After writing the new setting back to the transceiver, check and adjust the input (Recording) microphone level as before.

The next step is to adjust the audio from the PC to the rig. Adjust the Playback level so that your node’s locally‑

transmitted audio sounds clean. Disconnect from the Test server, then choose Tone Generator from EchoLink’s Tools

menu to produce a zero‑level tone into the TM‑D710. Choose Adjust Sound Device ‑> Playback from the Tools menu.

While listening on a nearby receiver, adjust the Playback (Wave) level so that the tone sounds full but not distorted.

COS Versus VOX

will detect an incoming signal whenever the transceiver’s squelch opens.

However, if the transceiver is tuned to the frequency pair of a local repeater, you might get better results by using

EchoLink’s VOX for carrier detect. When properly adjusted, this will avoid the extra delay imposed by the “tail” at the

end of each of the repeater’s transmissions. You may also want to enable EchoLink’s Squelch Crash Anti‑Trip feature to

preventincidentalsoundssuchascourtesytonesfromtrippingtheVOX.(SeetheEchoLinkHelplefordetailsonthis

the time that a signal is being received on its input. With this arrangement, you can set the TM‑D710 for tone squelch

instead of carrier squelch, and the rig will “open up” only during the time a station is speaking. This prevents the

repeater’stail,courtesytone,andotherincidentalsoundsfrombeingheardattheotherendofthelink,withoutaecting

the repeater’s operation for local users.

Using EchoLink only with Amateur Radio Equipment

If there is an EchoLink node within range of your transceiver, it is possible for you to access the node and communicate

via your transceiver with distant stations using the node.

You can search for nearby nodes at the EchoLink site at http://echolink.org.

Access the EchoLink site and click on “Link Status” in the menu on the left side of the screen.
