BASE is a 16-bit integer constant that provides the index offset for establishing the
RF frequency. For the MOD090-HP, this value is 1688.

MAX is an 8-bit integer constant that represents the number of RF channels that
the radio uses. For the MOD090-HP, this value is 19. It is important to save this
number because it tells you how many bytes of data to read next:

Byte 7 MK7 MK6 MK5 MK4 MK3 MK2 MK1 MK0
Byte 8 MK15 MK14 MK13 MK12 MK11 MK10 MK9 MK8
... Repeat MAX times to read all the values
MK is a 16-bit integer that contains the Index value for each RF channel. Bytes 7
and 8 will repeat until MAX values have been read. (For the MOD090-HP, this will
total 24 bytes, Byte7 through Byte30.)

Byte 31 DP7 DP6 DP5 DP4 DP3 DP2 DP1 DP0
Byte 32 DP15 DP14 DP13 DP12 DP11 DP10 DP9 DP8
DP is the 16-bit integer number of data points in the spectrum scan. The value will
depend upon the frequency step size specied in Byte1. The next 4 data bytes will
be repeated DP times.
