Feed Setup Pictures / New antenna
« Last post by captkel on Today at 06:20:10 AM »
I'm installing this antenna on Saturday 2/25/2017. It will be for some of the Miami feeds. I'll post
more photos when i'm done.

I'm going to change antennas today (after coffee). I will be shutting down the feeds at approximately 9am local time and should be back up
around 12 noon. I'll post a pictures later  :-D
Wow! to this controller.

American B738 declares an over weight landing emergency at Austin on 17 Feb when returning because of odour in cabin.
Thanks to Dave for  getting the EINN feeds back.

123.950 Unknown.

123.950 = Shanwick Oceanic Clearance Delivery (only used now by aircraft without CPDLC).

I know they are rare these days but if any of you HF guys happen to be monitoring HF and hear an eastbound Shannon VHF frequency assignment to a non CPDLC aircraft, can you post it here to try and help figure out Shannon frequency usage.

ie: BEDRA eta 0630Z at FL360 to 135.600 Shannon

Just found this website  (to see all listings use scroll bar on left)  ....

Appears to have been updated in 2016 and from the frequencies I have heard in use looks accurate.

Shannon ACC

High Altitude

Frequency = sector/area, (status, if heard in use recently), coordinates listed

120.040 = U1+U2+U3+UEXT, (confirmed), N52 42 W008 55 (SNN airport)
122.980 = U4, (NOTA, confirmed, primary), N57 W15 (SUNOT waypoint)
125.875 = U4, (NOTA, confirmed), N52 42 W 006 20 (typo? - 100nm SW of SNN)
127.130 = U1+U2+U3+UEXT, (confirmed), SNN airport
129.665 = U1+U2+U3+U4+U5, (status?), SNN airport
131.150 = U3, (confirmed, primary), SNN airport
132.150 = U1+U2+U3, (confirmed, primary), SNN airport
133.360 = U1+U2+U3+U4+U5, (status?), SNN airport
134.260 = U1+U2+U3, (confirmed), SNN airport
134.630 = U1+U2+U3+UEXT, (status?), N54 W15 (DOGAL waypoint)
135.230 = U1+U2+U3+UEXT, (status?), SNN airport
135.600 = U1+U2+U3+UEXT, (SOTA, confirmed, primary), SNN airport
135.730 = U1+U2+U3+UEXT, (status?), N54 W15 (DOGAL waypoint)
135.985 = U1+U2+U3+U4+U5, (status?), SNN airport
136.255 = U1+U2+U3+UEXT, (confirmed, used as sub for 134.260), SNN airport

Low Altitude

118.975 = L1, (spare?), SNN airport
119.075 = L1+L4, (north, confirmed), SNN airport, - however transmitter can be heard on the EIKN LiveATC feed (72nm north of SNN)
124.700 = L4, (south, confirmed), SNN airport
127.500 = L1, (south, confirmed), SNN airport
129.300 = L4, (spare?), SNN airport


124.175 = Oceanic (status?)
127.900 = Oceanic (status?)
131.825 = datalink ACARS
136.975 = datalink VDL

Trying to make sense of the "remarks" that appear to relate to sectors or areas, ie: "U4" corresponds with northern NOTA sectors and "U3" with 131.150 etc. Not sure what UEXT means ? Sector "U5" corresponds with 3 frequencies I've never heard used before ? Obviously the sector configuration and number of required frequencies varies quite a bit depending on traffic volume and location of the NAT tracks.

Still trying to confirm what transmitters are located in the Shannon area (that you are hearing the controller on), as far as I can tell it's only 131.150 and 132.150 high, and 124.700 low ? The coordinates given by the website don't seem to correspond to transmitter location as most are listed at the Shannon airport (clearly not the case) or some even co-located with navigation waypoints.

The Oceanic frequencies 124.175 and 127.900 were used in the past to assign HF frequencies and voice position reports at 15W, but this is now mostly done with CPDLC, although I have heard some HF frequencies being assigned by ATC on the regular frequencies. So not sure the status of these two anymore ?

Any additional information appreciated.

Hi Geoff,

Thanks for extending the audio. I was in a bit of a hurry because of many comments and emails I've received today to do this video so I came with the important comms from the Flybe, the consequent go arounds, ground stop and then a couple of miscellany I heard while diving through the feeds (unruly passenger and cabin not ready for departure) :lol:

Video is now available. Infographic :-)
