What happened to 122.75?

[ThrottleKing]

It's used in the practice areas around Pitt Meadows airport. I'm doing my PPL out of there and was trying to find where I would find this written down somewhere and arrived at this thread.. AIM? CFS? DAH? I guess it's just a "you gotta know", I guess no one is on 126.7 and this is just how it's always been done in that area.

Back in the UHF days in Europe, if an aircraft came up along side of you and made motions like "chambering a round" in a lever action rifle or the Lead said "Go Winchester", you dialed in 303.0

French forest 333.0

It's published on the back of the Vancouver VTA (alot of people miss the important info on the back of VTAs in today's digital Foreflight age). Fun fact you can find this info still in the "documents" section of Foreflight.

Though the frequencies published there are 122.725, rather than 122.75... I'm not from or familiar enough with the area to know why they'd be using 122.75 when .725 is clearly the published freq, I just happen to transit through every now and then. But in doing so I always monitor the published frequencies on the back of VTA.

123.4 - balloons, gliders, sailplanes, ultralights and hang gliders
123.45 - Air to Air in the Northern Domestic Airspace (NDA) and the NAT
122.75 - Air to Air in the Southern Domestic Airspace (SDA)





This is from the AIP:

VHF
The standard VHF air-ground channel spacing in Canada is 25 kHz. A 760-channel transceiver is necessary
for operation of 25-kHz channels. This channel spacing means that some operators with 50-kHz capability will
have their access to certain Canadian airspace and airports restricted, as 25 kHz channels are implemented
for air traffic control (ATC) purposes.
Air traffic service (ATS) frequencies are published in the Canada Flight Supplement (CFS), in the Canada Air
Pilot (CAP), and on aeronautical charts.
Frequency 123.4 MHz is allocated for the use of soaring activities, which include balloons, gliders, sailplanes,
ultralights and hang gliders. The use of this frequency for these activities includes air-to-air, air-to-ground
instructional and air-to-ground aerodrome traffic communications; the use of this frequency as an aerodrome
traffic frequency (ATF) is normally restricted to privately operated aerodromes used primarily for these
activities.
For air-to-air communications between pilots within Canadian Southern Domestic Airspace (SDA), the correct
frequency to use is 122.75 MHz; in the Northern Domestic Airspace (NDA) and the NAT, the frequency
allocated by ICAO is 123.45 MHz.
For flight information services enroute (FISE) throughout Canadian domestic airspace, remote communication
outlets (RCOs) have been installed. For information on this service, refer to the Canada Flight Supplement
(CFS), Section A, “General – Communications (CM).”

Just use the fingers, 123.45

Just use the fingers, 123.45

for pilots who are too lazy to look up / remember the proper frequency
