I only manage one of the half dozen or so L band data channels on Alphasat
Thanks for the example. It would be interesting to look over some recent Alphasat L band logs for uplinked CPDLC messages, just to see to what extent it's being used. (don't need to see the C band downlinks). Are these logs being archived anywhere ? Is there anyway to get a copy of some for say over a 24hr period (or longer, a few days) ? 

The only websites I'm aware of that do this are Ben's in California and the SatRadar24 site from South America, but neither have Alphasat coverage. (Maybe this isn't the best forum to discuss SATCOM stuff ?) 

the switch to VHF eastbound comes within ADS-B range , which makes sense.It looks like the actual switchover time would be 0637L
That switchover at 0637L appears to be the aircraft re-connecting with SATCOM (for data), which is a little odd as at that point it should have been well within VHF range for VDL2/ACARS, but that's another discussion. What I'm interested in is the voice handoff at 0632L, Shannon (SNNCPXA) instructing the flight to switch to another Shannon VHF voice frequency 134.260. This would not have been the initial voice call on VHF as that would have been issued from Shanwick (PIKCPYA) around time 0600L. Either you missed it or it was on another channel or satellite ?

Shannon's sector configuration and frequency use is quite dynamic changing daily depending on the traffic flow (NAT Tracks) so the more data the better. Although now with the reduced traffic flow it's not as complicated as it was in the past. Ben was nice enough to give me access to his daily logs and so far I'm seeing around 10 of these Shannon handoff messages from Shanwick per day, that's on the North American Satellite. I'm curious how many of these messages you would get daily on the Alphasat 25 ?

Re: Shanwick SATCOM CPDLC handoffs to Shannon

All,

I got some messages that seem to fit the pattern you are looking for overnight from my L-Band station (nothing on HF thus far).
Here is a small sample.
23:10:24 31-08-20 AES:76CCCD GES:43 2 .9V-SFM !

I also got some messages that just had 'VHF' in them. 
Are these also of interest?
 05:41:27 01-09-20 AES:4D0115 GES:D0 2 .LX-ECV !

Let me know about either.
I can go ahead and log them to a text file and set up automatic email every 24 hours.

Hi Ben

Alphasat 25 east is the best bet for these frequencies.
I monitor 8 C band downlinks  from 25 east and rarely see freqs for
Oceanic mentioned but they are certainly there on L band [ which I don't
cover at present ]  I'll try and set up a test later to see what pops up
. that will give us both sides of the pond.

It's picking up the data from Inmarsat 4F3, so it should be, but I can't say for sure.
Right now I am getting around 75 L-Band messages per hour, so we'll just have to wait and see.

How easy is it for you to filter for that specific message type only
? Can you search for "EISN" and "VHF" in the same message ? The
problem with only searching EISN is that a few other types of
massages also include it.

Ok, I have set up that filter on both L-Band and HF.
For now, I am just going to display the data in a table on my website.
If I get some hits, I can write it to a report file and see about sending you an email every 24 hours. (If you like).

The question I can't answer is if my L-Band covers the Shanwick Oceanic area.
It's picking up the data from Inmarsat 4F3, so it should be, but I can't say for sure.

Right now I am getting around 75 L-Band messages per hour, so we'll just have to wait and see.

Sorry for the noob question (I am still very much wrapping my head around all this).

Do you need HF or C-Band or L-Band data?
Here is my 48 hours of C-Band coverage map;

I seem to cover that part of the globe, so could set up a filter for those messages.

If anyone has recent logs they are willing to share it would be appreciated. You used to see a lot of these on the SatRadar24 site but recently reception in that area has become very sporadic, much more so than can be explained by the reduction in traffic.
