<p> where:
</p>
<p> AM = amplitude modulated<br>
SSB = amplitude modulated and uses a single-sideband, suppressed carrier<br>
FM = angle modulated and uses frequency modulation and<br>
PM = angle modulated and uses phase modulation.<br>
</p>
<p>It can be seen that packet may be a number of emission modes,
however, those for SSB, FM &amp; PM would normally be used given that
AM packet would be a rare beast (but not impossible between cooperating
stations).<br>
</p>
<p>From Schedule 1 of the LCD, with my additions in [ ]<br>

<p>For the first letter;</p>
<p>A - Amplitude Modulated and using double sideband [AM]<br>
J - Amplitude Modulated and uses a single sideband, suppressed carrier
[SSB]<br>
F - Is angle modulated and uses frequency modulation [FM]<br>
G - Is angle modulated and uses Phase modulation [PM]<br>
</p>
<p>For the number;<br>
</p>
<p>1 - Signal modulating the main carrier is a single channel
containing quantized<br>
 or digital information without the use of a modulating subcarrier<br>
</p>
2 - Signal modulating the main carrier is a single channel containing
quantized<br>
or digital information with the use of a modulating subcarrier<br>
<br>
Finally, the last letter;<br>
<br>
D - Data transmission, telemetry or telecommand<br>
<br>
It's all a piece of cake :-)<br>

Just out of curiosity, what IS the emission mode of packet?<br>
