Rean Opperman 923715 Posted October 14, 2019 at 07:19 PM Posted October 14, 2019 at 07:19 PM Hi there, We've been doing some extensive testing today, and found something strange. On both Cape Town (FACT) and Johannesburg (FAOR), there is extremely degraded voice quality on the TWR and APP frequencies - eventhough theoretically the transmitters should be very close to the aircraft. Aircraft all at very close range (mostly on the ramp/apron). These frequencies are pulled from the Euroscope client, not defined on the servers. The same issue does NOT occur with center frequencies though, if a plane is near a transceiver (as set up on the servers) audio quality is perfect. Is there any technical reason for this?

Matthew Bartels Posted October 14, 2019 at 07:31 PM Posted October 14, 2019 at 07:31 PM Ensure that the visibility center in EuroScope is centered over the airport. It's likely that the visibility center is not thus placing the transceiver off the airport somewhere resulting in that degradation. If that does not fix it then have your facilities engineer place a transceiver on the airport through the station editor and [Mod - Happy Thoughts]ign it to your positions.

Hi Matthew, We double-checked the vis points, they were perfectly centered on the airport. Didn't help - even if we slewed the plane up to gain some altitude it was still just as degraded. Adding it into the facilities database worked perfectly. That does mean we have to do it for GND, TWR and APP for all our airports though I [Mod - Happy Thoughts]ume? Just concerned it'll mean a LOT of added transceivers at the end of the day. Rean Opperman - ACCSAF1 South Africa vACC (ACCSAF) Link to comment Share on other sites More sharing options...

There is definitely something odd going on there. perhaps trying to add additional transceivers via controller client source on the airport itself would resolve those issues. Otherwise you only need one transceiver defined at the airport. you can created all of your airport positions to use that same one.

Thanks Matt - spoke to our facility engineer this evening and he will begin adding all the major airports in South Africa to the database (with 1 transceiver each, with all 3 stations for each airport defined on it). We have taken care to keep the number of our center transceivers in SA as low as possible. Basically we're doing it as close to real-world as we can, with transceivers placed where they are in the real-world. Basically comes down to about 9 transceivers per center (we have 2 centers in SA, north & south). So we haven't totally flooded the database with transceivers yet Rean Opperman - ACCSAF1 South Africa vACC (ACCSAF) Link to comment Share on other sites More sharing options...
