^rPL Deviation medium^r

The pl deviation value  depends on the channel spacing  you have choosen
in the configuration menu. The exact value can be found in the following
table:

     |           |  PL deviation   |  PL deviation   |
     |    PL     |  for 20/25 KHz  |  for 12.5 KHz   |
     | deviation | channel spacing | channel spacing |
     +-----------+-----------------+-----------------+
     |  low      |      500 Hz     |     250 Hz      |
     |  medium   |      750 Hz     |     375 Hz      |
     |  high     |     1000 Hz     |     500 Hz      |

     Standard setting is PL Deviation medium.

When the radio is tuned for voice modulation for 25 KHz spacing channels
the deviation  is set at about 4.8 KHz.  Now when the pl is  selected on
this channel the audio filter IC sums up the two signals to still result
in  4.8 KHz of total modulation.  The voice is automatically compensated
to prevent over modulation when pl is present.  Therefore when 750 Hz pl
deviation is selected the voice would be 4.80-0.75 = 4.05 KHz. If 500 Hz
was used for pl then the voice would be 4.3 KHz.  A 1000 Hz pl deviation
is only meant for connect tones in trunking systems.
If however  a 12.5 KHZ spacing channel was  chosen all the  above pl and
voice deviations would be correspondingly halved.
