Title: ZDC Calvert Feed
Post by: MIAMIATC on April 18, 2023, 12:10:09 PM

I dont know if any has noticed this but the feed appears to be on a delay broadcast and not actually live.  I have been syncing it up to my flight trackers and it appears to be on a 10 minute delay broadcast .

Checking it at 1400 EDT and the feed seems to be about 1 minute behind from what I see on ADS-B Exchange.

For the first few minutes you start the feed its live but after a while it goes to the point where it is not anymore. I had a transmission of a handoff from 133.9 to 118.75 going into RDU and FR24 showed the aircraft as landed status but the radio teransmission would have had the aircraft still by GARED intersection

That's weird. I haven't seen this myself yet.  This is one of the new feeds that just went live a few weeks ago.  There are other frequencies set up the same way so I wonder if this is happening on these other freqs as well... will monitor and see...any idea how long it took before this issue started?

Well, that's good to know  :-)  I was listening to 133.9 Calvert for quite some time this morning and so far I haven't seen what you've seen.  Haven't given up though!  The way you described it, it almost seems like the feed went into a pause mode and then resumed some time later where it left off.  Not sure how that could happen on its own though.

OK, so I listened to the Calvert feed on my PC for roughly 3 hours but could not see what you were seeing.  It may have been behind by a minute or two, but not beyond that.  Were you able to see this repeatedly?

Quick update... it seems the time-delay issue that you saw can happen when you listen to the feed from one of the web-based players on a PC/laptop.  I finally saw this myself not too long ago.  I don't know why it happens like that but I do know that this problem doesn't exist when listening through the app.
