Certain modulation schemes, or communications techniques are incompatible with each other and wherever possible should not share a sub-band.

Certain sub-bands are allocated in every IARU Region of the world using the same frequencies, so hams can communicate continentally, hemispherically and worldwide. Thus the bandplans conform with those in use in IARU Regions 1,2 and 3 on an overall basis, but have a unique Canadian flavor.

Technology is evolving rapidly in the area of digital communications (not just AX.25 Packet)and the bandplans make allowance for development of these technologies, and ultimately the adoption of digital modulation schemes for the majority of amateur communications voice, data and Video. Our only limits are IC mandated bandwidth, spectrum conservation issues, and interference issues. did I say "only"? HI)

Wherever possible responsibility for allocations in sub-bands where frequency coordination occurs rests with the "local coordination body". The only constraints on that body are the upper and lower limits of the particular coordinated sub-band.

Where potential for interference occurs, it is up to local coordination body, and the affected parties to work together to resolve the interference, using the most advantageous technical and administrative means possible. This could include tone squelch, sharing based on time of day, frequency offset from the channel center, polarization, ERP, radiation pattern control, remote control, etc.

We recognize that the bandplans will not satisfy everyone, but they provide a compromise that supports the principles of amateur radio and RAC's bylaws.

Footnotes:

(1) Digital Channelling 25 Khz "minimum" raster, contiguous multiples of 25 Khz should be released based on required Digital System Bandwidth. (Data Rate and Modulation scheme will govern bandwidth). Consult with your local coordinating body, or RAC where no coordination exists.

(2) Once communications has been established, QSY off frequency to allow others to call.

(3) ATV operations may be for point to point, or repeater input operations. Note that any non ATV activity below 444.0 Mhz must be coordinated with ATV users to minimize or eliminate interference to the video signal.

Consult with RAC for advice on administrative and technical means to achieve this. Note that Double Sideband Video is NOT sanctioned from a technical, spectrum, interference and power conservation viewpoint.

Note that non video Digital operations in this sub-band should only occur if other frequencies allocated are exhausted, consult with your local coordination body.

(4) Local Option - consult with your local coordinating body.

(5) Repeaters - includes Narrowband FM, ACSSB, Digital(Voice, video and data)modes. Frequencies must be coordinated with your local coordinating body, or RAC VHF UHF Advisory where no coordination body exists.

(6) Non conforming analog links on 70 cm are grandfathered provided that their existence does not cause harmful interference with amateur operations designated for that sub-band. In the case of interference, coordination discussions must be held to resolve the problem. Note grandfathering ceases once that link goes out of service, consult with your local coordinating body.

(7) Digital operations may include repeater operation, crossband duplex operation, links or simplex. Consult with your local coordination body.

(8) RAC encourages development of Digital compression techniques to reduce video bandwidth within this sub-band.

(9) Spread Spectrum centre frequency, secondary, operations per IC bandwidth limit of 12 Mhz (max spreading), may occur within these sub-bands, but must not cause interference to primary Amateur systems.

(10) Propagation Beacon frequencies are to be coordinated through the RAC VHF UHF Advisory Committee.

RAC encourages the use of CTSS encoding where spectral congestion occurs.
