1. Multiple callsigns used with a single rig.

2. Portable indicators are not necessarily shown when in call area indicated by callsign.

3. Contacts above 275 GHz only between licensed radio amateurs are shown in the records table, to encourage experimentation. Transmitters must employ coherent signals (e.g. lasers, not light bulbs) and receivers must employ at least one stage of electronic detection. Multiple records may be shown if claims are made for significantly different frequencies of operation (for example sub-millimetre waves, infrared, visible light). Such operation is not covered by the regulations pertaining to Amateur Radio. Operators using these frequencies are responsible for ensuring that they meet any applicable regulations, such as those pertaining to safe use of lasers outdoors.

This table was generated based solely on QSOs of which VE3SMA is aware. To distinguish laboratory curiosities from real communications capability a minimum distance of 1 km has been assumed to be listed here. To be listed, claimants will have to provide both call signs, distance and date of the QSO. I am unaware of any QSOs involving stations in Canada on bands between 50 and 275 GHz. Peter Shilton, VE3AX, is compiling Canadian distance record data for the bands between 144 and 2450 MHz. Please send your claims for these bands to him at ve2pij at qsl.net.

Where more than one QSO is shown as a first, it is because the stations made the QSOs within a period of a few minutes and can be considered co-holders of the "title". Where more than one QSO is shown as a distance record it is because the exact path has been worked more than once by different stations, or (for now) only partial data has been received from the likely record holder.
