There are two techniques a repeater is linked to EchoLink.

Utilizing the “hard-wired” approach, the PC on which EchoLink runs happens to be co-located employing the repeater controller, and interfaced straight to they, without having added RF components.

This permits glowing carrier and PTT regulation within the repeater operator and EchoLink, and takes away further “hops” in mp3 sequence. What’s more, it removes the need to ID the link sender. One disadvantage of this technique, but is it will require trusted access to the internet at repeater site, that might be in an isolated location.

With this setup, the transceiver acts just like an ordinary local repeater owner, shifting on repeater’s insight regularity (on the part of EchoLink owners) and receiving throughout the repeater’s result consistency. Even though this let the EchoLink technology to be put in a more easy place, it offers some issues regarding RX management.

With either method, EchoLink must certanly be set up with a callsign with a -R suffix, to point out that the node is actually a portal to a repeater, instead of a simplex frequency. If a remote backlink is being put, the application must always be configured to understand alone on the environment with the number station’s callsign, and that is not necessarily the same as the EchoLink callsign (and the callsign with the repeater). Because the website link is not a repeater, a suffix for example /R within the ID is typically not just proper (for U.S. programs).

The most essential factors to consider for an EchoLink repeater node could be the strategy for finding the existence of a regional RF indicator. Although top way should be to wire a COS signal in to the COM slot of Computer, it can be essential (or attractive) to use VOX as an alternative. A few steps become discussed below.

COS from Repeater Receiver: In the event that node are hard-wired to the repeater control, the very best cause of company discover is the COS result within the repeater radio itself — or an equivalent indication within the repeater controller. This ensures that EchoLink transfers to the web as long as an indication is now being obtained throughout the feedback. Additionally, the audio link to the seem cards should come from the receiver’s audio output, instead of the repeater sender’s sound path.

COS from back link Transceiver: when node is actually from another location operating, it could be desirable to make use of the COS indication from your link transceiver — but as long as the repeater’s “tail” is incredibly shorter. Otherwise, EchoLink keep sending online five to ten mere seconds as soon as the neighborhood consumer finishes a transmission, severely interrupting the circulation of a QSO. Some repeater-node providers bring properly contained DTMF tones in their traditions be connected and detachment notices to quickly shorten the repeater’s “tail” while an EchoLink station are linked, on repeaters which help this particular isolated demand.

VOX: when node is actually from another location set, nonetheless repeater’s “tail” is not to be shortened, VOX works extremely well. Whenever effectively altered, EchoLink will recognize words data emerging with the repeater, but dismiss various other incidentals for example the “tail”, the courtesy overall tone, while the squelch collision at the conclusion. This is very important whenever two repeaters become associated with friends, to avoid unlimited ping-ponging of just one repeater discussing one more. Below are great tips for modifying the VOX to be used with a repeater:

1. Fix the VOX tolerance carefully. (This is horizontal slider under the audio-level signal.) The VOX tolerance need specify right above the mp3 standard of the repeater’s useless carrier, in order that it “vacations” on sounds, however the repeater’s trail. View the purple SIG annunciator while adjusting the VOX limit.
2. When necessary, set the VOX lag time. The traditional value of 1200 ms is acceptable in many scenarios. (if you choose to change the importance, sort it in straight, versus utilizing the up-down links.)
3. Operate the “Intelligent VOX” feature. This is exactly permitted by checking out the “Squelch accident Anti-Trip” container about RX Ctrl tab. Once this ability are permitted, EchoLink’s VOX will disregard shorter interference blasts, like the repeater’s politeness overall tone together with the squelch accident if the repeater’s company falls. Ready the effort consistent to a value a little bit more than the longer top two signals. Typical methods tend to be 250 ms for a repeater with a (close) complimentary overall tone, or 80 ms for a repeater without any politeness tone. Remember that the clever VOX characteristic cannot necessarily reduce these data from inside the cd route, they only hinders these people from inducing (or retaining open) the VOX.
4. Anti-Thump: take advantage of Anti-Thump element if your squelch accident, just as seen across repeater if your transceiver puts a stop to shifting, appear to be ferzu mobilní web activating the VOX. Start out with a decreased worth and go it bit by bit improved through to the SIG warning not any longer shows up when your url halts transferring.

As soon as the VOX is properly adjusted, the “acid sample” is always to hook up the hyperlink toward the *ECHOTEST* discussion servers. After experiencing the original welcome message from the try host, the repeater should decrease typically right after which stays lazy. If repeater remains keyed-up by feedback from the taste server, re-check the adjustments.

Whenever the background are actually correct at both finishes of a repeater-to-repeater website link, both repeaters should continue to be idle except during an authentic QSO, or while either repeater transmits the identification.
