Nice work! Does anyone know where I could find a breakdown of the emission types? It would be nice to look at a list like that and see which ones switched to digital (MotoTRBO etc).

Those would be all the licenses/frequencies that had a change of some sort over the past month.

Nice work! Does anyone know where I could find a breakdown of the emission types?
The first four characters are signal bandwidth; for the rest, IC provides this breakdown:
Code:
              INDUSTRY CANADA/INDUSTRIE CANADA
                           TABLE II
                      CLASS OF EMISSION
================================================================
                         FIRST COLUMN
================================================================
CODE   TYPE OF MODULATION
================================================================
N      Emission of an unmodulated carrier.
Emission in which the main carrier is amplitude modulated.
(Including cases where sub-carriers are angle modulated.)
A      Double-sideband.
H      Single-sideband, full carrier.
R      Single-sideband, reduced or variable level carrier.
J      Single-sideband, suppresed carrier.
B      Independant Sideband.
C      Vestigal sideband.
Emission in which the main carrier is angle-modulated.
F      Frequency Modulation.
G      Phase modulation.
D      Emission in which the main carrier is amplitude and
       angle-modulated either simulataneously or in a pre-
       established sequence.
Emission of Pulses
P      Unmodulated sequence of pulses.
A      Sequence of pulses.
K      Modulated in amplitude.
L      Modulated in width duration
M      Modulated in position/phase.
Q      In which the carrier is angle-modulated during the
       period of the pulse.
V      Which is a combination of the foregoing or is produced
       by other means.
W      Cases not covered above, in which an emission consists
       of the main carrier modulated, either simultaneously
       or in a pre-established sequence, in a combination of
       two or more of the following modes: amplitude, angle,
       pulse.
X      Cases not otherwise covered.
================================================================
                         SECOND COLUMN
================================================================
CODE     NATURE OF SIGNAL(S)
================================================================
0      No modulating signal.
1      A single channel containing quantitized or digital
       information without the use of a modulating sub-carrier.
2      A single channel containing quantitized or digital
       information in with the use of a modulating sub-carrier.
3      A single channel containing analogue information.
7      Two or more channels containing quantitized or digital
       information
8      Two or more channels containing analogue information.
9      Composite systems with one or more channels containing
       quantitized or digital information, together with one
       or more channels containing analogue information.
X      Cases not otherwise covered.
================================================================
                         THIRD COLUMN
================================================================
CODE   TYPE OF INFORMATION
================================================================
N      No information transmitted.
A      Telegraphy - for aural reception.
B      Telegraphy - for automatic reception.
C      Facsimile.
D      Data transmission, telemetry, and telecommand.
E      Telephony ( including sound broadcasting).
F      Television (video).
W      Combination of the above.
X      Cases not otherwise covered.
================================================================
                         FOURTH COLUMN
================================================================
CODE   DETAILS OF SIGNAL(s)
================================================================
A      Two-condition code with elements of differing numbers
       and/or durations.
B      Two-condition code with elements of the same number
       and duration without error - correction.
C      Two-condition code with elements of the same number
       and duration with error - correction.
D      Four-condition code in which each condition represents
       a signal element (of one or more bits).
E      Multi-condition code in which each condition represents
       a siganl element (of one or more bits).
F      Multi-condition code in which each condition or
       combination of conditions represents a character.
G      Sound of broadcasting quality (monophonic).
H      Sound of broadcasting quality (stereophonic or
       quadrophonic).
J      Sound of commercial quality (excluding categories given
       under K and L below).
K      Sound of commercial quality with the use of frequency
       inversion or band-splitting.
L      Sound of commercial quality with separate frequency-
       modulated signals to control the level of demodulated
       signals.
M      Monochrome.
N      Colour
W      Combination of the above
X      Cases not otherwise covered.
================================================================
                         FIFTH COLUMN
================================================================
CODE   NATURE OF MULTIPLEXING
================================================================
N      None.
C      Code-division.
F      Frequency-divsion multiplex.
T      Time-division multiplex.
W      Combination of frequency-division multiplex and
       time-division multiplex.
X      Other types of multiplexing.

It would be nice to look at a list like that and see which ones switched to digital (MotoTRBO etc).
It looks like IC uses EM1=16K0F3EJN EM2=16K0F2D-N for TRBO, so I'll have to add an EM2 field to the report.

Also, I'm not currently looking for changes in the emissions fields, so analog-->TRBO changes wouldn't show up. Perhaps a separate changed emissions report would be the best route?


Those would be all the licenses/frequencies that had a change of some sort over the past month.
I only matched records that have the same TX/RX frequencies, licensee name, location text and lat/long; any unmatched records are treated as an addition or deletion.

Other changes (emissions type, ERP, etc.) are ignored.

Hey that's pretty good! If there's one thing I hate, it's trying to work with the TAFL text files... I use some of the handy search engines some people have online, and try to use those to determine new additions, but something that would show deletions as well is awesome!
Now if only I was in Ontario :lol:

very well done, mkes keeping up with local changes a lot easier.

What would be extremly usefull would be a list that includes all the frequency assignments not shown in TAFL.

maybe a wiki type TAFL might be possible where members can add in known but not listed freq (marked as additions) to a "master list".

Link is still showing --
TAFL-Diff for period 01-Nov-2011 to 01-Dec-2011
...and would that not be correct? Showing the changes for the past month?

None of the changes listed for London Fire represent frequency changes (or new frequencies). Everything listed either belongs to one of the 4 EDACS sites, I-Call or I-Tac channels, or county channels. Emission type changes for the upcoming move to P25 perhaps?

Great idea ... any way to keep a record of previous changes?

Ya London Fire is adding a lot of frequencies
You can also see the WIND MOBILE expansion into Niagara, Port Colborne Fort Erie, Welland,

Pretty cool... as always slicerwizard really comes up with some good stuff on his site.
