Query
9 bytes Command or Query.
Sets or returns Rx Frequency ranges in MHz, in 100Hz steps, in the form xxxx.xxxx where:
xxxx.xxxx=value from 50 MHz to 180 MHz (70/140 MHz), or from 950 MHz to 2150 MHz (L-Band)
EXAMPLE: <0/RFQ=0950.9872
1 byte, value of 0 Query only.
or 1 Returns Rx 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/RFM?
>0000/RFM=1 (Short Block mode)
