I've been bouncing around the various Potomac APP frequencies and realized I never seem to hear aircraft departing BWI on the SWANN3 SID. Maybe I'm just not in the right place at the right time, but what is the usual initial departure frequency for that SID?

Thanks!

I am sure, they asked you not for getting an accurate information about definite stage of flight but just to stimulate you for speaking English, for demonstrating it through your ideas. SOMETIMES, examiners are forced to speculate on the point

On 15 April around 14:00 UTC, flight SWR193E from Barcelona to Zurich made a little lovely detour from its usual flight path. Turned right at French/Italian border, flew towards Matterhorn and then turned back on its original intended track. (A friend of mine was on this flight and apparently, the pilot took them intentionally - because of great weather and visibility - on a little tour round the Alps:) ) I was wondering: which ATC would the flight talk to in order to request clearance to do this? French en-route? Italian en-route? Swiss en-route? Or anyone else? Any suggestions? I would love to hear that conversation Smiley

A link to the flight below.

It was changed due to interference on 127.4. That is the only frequency change at the moment, unless you're inquiring about any procedural changes.

As for 120.425, it was found during a routine band scan and shows up with a ? on this page:

Okay after further checking I see it is a new Montreal Terminal (Departure) frequency. The same info. I have also lists 118.075 as a new Departure frequency as well. These 2 new frequencies were added as part of a Montreal Terminal Airspace redesign back in March of 2013.

Also on the Center feed you have 132.55 listed. I haven't listened to that area in depth recently but from what I recall it seems (?) they have stopped using 132.55 and replaced it with just 132.350 (merged the sectors permanetly ?). From what I've heard so far it doesn't appear you are hearing the controller in that sector ?

As far as I can tell so far the only Center controller you are able to hear on the Center feed is on 135.600. This frequency appears to be cross-coupled at all times with 128.775 (Ottawa - south area), 126.575 (Mount Laurier - north area), and 133.900 (YFJ area).

From what I've heard so far this is what I think you should cover on the Montreal Center (low) feed.

135.600
128.225
132.350

120.425 should be removed and added to the Terminal radio

And if you get a dedicated Montreal Center (High) feed.

134.400 (covers 127.875)
133.225
123.925

133.225 and 123.925 are almost always cross-coupled into one sector, but you wont get the controllers in Monteral. During the overnight hours all sectors are combined and would be heard on 134.400 (cross-coupled).

What else would be worth scanning?

I would be interested in a feed covering 134.400. The transmitter is located in Montreal. This is a high altitude sector (FL290 and above) covering the airspace west of Montreal. The frequency is also cross-coupled with 127.875. This would cover that airspace from overhead Montreal towards Ottawa to the border with Toronto as well as north up to the border with the airspace covered by the Noranda radio. I would donate a radio for a dedicated feed to 134.400.

I notice on the CZUL Center (Montreal) feed you list 120.425 as a Montreal Center frequency. Just wondering what your source is for that, first time I've heard of that frequency ?



Well, thanks for the offer but it's premature to dedicate a radio right now to just one Center frequency.  First we'll have to see if we even hear the ground side on 134.400.  We may be able to do it, but I can't make a promise.  What may make more sense is eliminate all the frequencies where we can't hear the ground side. 

As for 120.425, it was found during a routine band scan and shows up with a ? on this page:

http://www.canairradio.com/qc.html

as both a Terminal departure frequency and a CYUL frequency.  I will find out from the FIR which one it is.

We are making some changes/additions to our Montreal feed stack.  Right now things are in a little bit of a state of flux but the current feeds are here:

http://www.liveatc.net/search/?icao=cyul

(with the exception of Noranda which is not broadcast out of Montreal)

Recent changes:
- now broadcasting all CYUL Tower frequencies
- addition of some ground freqs
- addition of some CZUL (Montreal Center) frequencies which broadcast from (even if only occasionally) the Montreal area.  On this feed we may still have 125.150, which is a CZUL frequency that handles arrivals/departures into CYHU St. Hubert (that frequency is not listed on this feed right now but is still scanning on it for now as we work on things).

Some things we are trying to figure out:

1) Is it Montreal Terminal or Montreal Center that actually handles IFR traffic into and out of CYHU?
2) Should we move 125.150 to the CYUL Approach feed instead?
3) Does anyone have deeper knowledge of the CZUL transmitters/frequencies allegedly in and around CYUL?

What else would be worth scanning?  We might be able to add a receiver for further splitting but not before we understand the use of repeaters around CYUL.  It seems that there is heavy use of such in the area for both CYUL and CZUL. 

See these references for more info:

http://www.canairradio.com/qc.html


First off, thank you for the new feed addition. Frequency 128.775 is of interest to me.

I obtained a few outdated Nav Canada en-route charts posted on ivao.ca (dated February 9, 2012), and I'll try to answer question 3:
- 128.225 Rawdon Sector located in Trois-Rivieres, Quebec
- 128.775 Thurso Sector located in Ottawa, ON (which is combined with frequency 126.575 at Mont-Laurier, Quebec, as mentioned in this thread: http://www.liveatc.net/forums/listener-forum/question-regarding-montreal-centre-frequencies-134-975-and-128-775-%28ottawa-area%29/)
- 132.550 Gransby Sector located in Sherbrooke, Quebec
- 135.600 might be located in Montreal

Not sure if this helps.
