NOTES FOR THE ABOVE BAND
PLAN TABLE
(1) - Point-to-point links will be ground-to-communications site
only. Communication-site-to-communication-site links will not be allowed.
Repeater and Point-to-Point Links
Emissions = 13K6F3E, +/-2.5kHz maximum deviation
3kHz highest applied audio
frequency
Transmitter Audio Lowpass Filter Attenuation for 3kHz to 20kHz = 100log(f/3)
where f = frequency in kHz
Channel Spacing = 12.5kHz (902.1125/927.1125 to 902.9875/927.9875,
etc...)
Repeater Spacing (for offset 'A') = 25MHz
Repeater Spacing (for offset 'B') = 22MHz
Frequency Tolerance (fixed and mobile) = 1.5ppm (0.00015%)
9xx.9000MHz repeater frequencies reserved for open repeater coordinations
(2) - GROUP repeater input channels for multiple system use; low noise
channels, restricted to 5W ERP. Multiple coordinees per channel.
Never as a coordinee's primary input. Use limited to auxiliary repeater
inputs only.
(3) - Wideband digital ground transmit only.
(4) - FM ATV: Ground simplex transmit only or repeater input paired with
other band repeater output. No high-level site transmit permitted.
100W ERP directional maximum. 10W ERP omni-directional maximum.
Video deviation 3MHz. Occupied bandwidth 12MHz (including all subcarriers).
Overlap with an AM ATV repeater output on 919.25MHz will be handled on
case-by-case coordination. Use of optional 912MHz carrier requires tight
transmit bandwidth control. Digital TV allowed but must conform to the
current 6MHz bandwidth usage.
(5) - Wideband digital communications site transmit only.
Horizontally polarized, directional, 2W ERP maximum.
(6) - Simplex point-to-point links will be ground-to-ground or
ground-to-communication-site only.
Communication-site-to-communication-site links will not be allowed.
