The frequency channel to work on. Each channel corresponds to a given
pair of transmit and receive frequencies, depending on the ODU's
Standard (US/European), Spectrum Range Allocation (38 Ghz, 23 Ghz,
18 Ghz, etc...), Duplex Spacing (700 Mhz, 1200 Mhz, 1010 Mhz, etc...)
and Frequency Band (1, 2, 3 or 4) (see wvOduPartNo below).
The channel nos. spacing follow the h/w resolution, that is 0.25 Mhz.
According to the FCC standard, each chosen frequency has a minimum spacing
of 2.5 Mhz, therefore on FCC allocations the first and last allowed frequency
centers are 1.25 Mhz from the start/end of the below specified bands, leaving
5 channels on start side and 4 on the end side not selectable (maybe more,
depending on additional restrictions specific to each Duplex Spacing).
According to the ETSI standard, each chosen frequency has a minimum spacing
of 3.5 Mhz, therefore on ETSI allocations the first and last allowed frequency
centers are 1.75 Mhz from the start/end of the below specified bands, leaving
7 channels on start side and 6 on the end side not selectable (maybe more,
depending on additional restrictions specific to each Duplex Spacing).

is deduced from the Tx frequency as follows:

The first/last allowed wvChannelNo depends on the used channel spacing and
is calculated as follows:
first = 15 for 7MHz, 30 for 14MHz , 60 for 28MHa

Valid wvChannelSpacing are 14MHz & 28MHz
NOTES:
1. Valid channel numbers are n*15 n= 1,2,3...,32
2. When we display the transmit frequency the format is MMMM.KK and we
trunk the least significant numbers.
