The data string in response to a status enquiry command - '\' is as
follows:
RS232, 1200 baud (fixed), 30 bytes, left to right.
Byte 1-7: current displayed frequency to 10 Hz. 7.33500 MHz is
00070303050000
8: MODE (more or less)
bit 7 = FAST LED
bit 6 = RTTY
bit 5 = FM
bit 4 = AM
bit 3 = LSB
bit 2 = USB
bit 1 = CW
bit 0 = TUNE (LSB on =x'08')
9: FILTER (more or less)
bit 7 = 6.0 kHz
bit 6 = 2.4 kHz
bit 5 = 1.8 kHz
bit 4 = .50 kHz
bit 3 = .25 kHz
bit 2 = RX offset
bit 1 = TX offset
bit 0 = LOCK (RX offset on = x'40')
10: MISC
bit 7 = DATE LED
bit 6 = TIME LED
bit 5 = OFFSET LED
bit 4 = MEMORY LED
bit 3 = VFO A
bit 2 = VFO B
bit 1 = SPLIT LED
bit 0 = TAG LED
11: BAND RELAY
bit 7 = 22-30 MHz
bit 6 = 15-22 MHz
bit 5 = 10.5-15 MHz
bit 4 = 6.5-10.5 MHz
bit 3 = 4-6.-6.5 MHz
bit 2 = 2.5-4 MHz
bit 1 = 1.7-2.5 MHz
bit 0 = 0.1-1.7 MHz
12: MEMORY CHANNEL (binary)
x'63' = no memory channel shown
x'FE' = memories full
13: STEP SIZE
x'00' = 10 Hz
x'01' = 20 Hz
x'02' = 50 Hz
x'03' = 100 Hz
x'04' = 500 Hz
