Response to Query
Tx Frequency TFQ = 9 bytes Command or Query.
Sets or returns Tx Frequency in MHz, in 100Hz steps, in the form xxxx.xxxx where:
xxxx.xxxx = 50 MHz to 180 MHz (70/140 MHz), or 950 MHz to 2150 MHz (L-Band)

Tx Framing
Mode
TFM = 1 byte, 0 or 1 Command or Query.
Sets or returns Tx Framing mode in the form x, where:
0 = Normal Block
1 = Short Block
NOTE: Not all Network Specs will support both Framing Modes.
EXAMPLE: <0/TFM=1 (selects Short Block mode)
