Omni VII Programmer's Reference Manual

| Format:|‘’ [‘A’ or ‘B’] | | Where:| ‘’ = the ASCII ‘*’ symbol (0x2a) | A = the ASCII ‘A’ character (0x41) B = the ASCII ‘B’ character (0x41) <d3..d0> = Frequency in Hz as a 4 byte binary number. The most significant byte is d3. The least significant byte is d0. Example1: *A<0x00><0xe4><0xe1><0xc0> sets the main VFO to 15,000,000 Hz or 15 MHz. Example2: *B<0x00><0x5b><0x2b><0xd8> sets the sub VFO to 5,975,000 Hz or 5.975 MHz. Example3: *A<0x03><0x37><0xF9><0x81> requests to set the main VFO to 54,000,001Hz. However, the radio will limit it to 54,000,000Hz.

The Internal Keyer Speed can be controlled with a range of 5..63wpm. The data range is 0..127, meaning that the value sent is Desired_Speed * 127/63.

Mode

Format:‘*’ ‘M’ <d1> <d0> <CR>
Where:‘*’ = the ASCII ‘*’ symbol (0x2a) M = the ASCII ‘M’ character (0x4d) <d0> = setting for VFOA mode <d1> = setting for VFOB mode
= ASCII ‘0’ (0x30) for AM Mode = ASCII ‘1’ (0x31) for USB Mode = ASCII ‘2’ (0x32) for LSB Mode = ASCII ‘3’ (0x33) for CWU Mode = ASCII ‘4’ (0x34) for FM Mode
= ASCII ‘5’ (0x35) for CWL Mode = ASCII ‘6’ (0x36) for FSK Mode
Example 1: *M11<CR> sets USB for VFO-A, USB for VFO-B 
Example 2: *M35<CR> sets CWU for VFO-A, CWL for VFO-B

CK to test keyer On/Off. ?C2L to read keyer speed setting. Returns *C2L ?C2G to read weighting setting. ?C1L to read sidetone frequency. ?C1Q to read sidetone volume. _?CD to read CW attach/decay dynamics. _ ?C1M to read QSK delay setting.

*C2L # Note do the calculation above so 50wpm is 64h Indicates CW Speed set to 40 WPM.

## CW Sending

CW Character Send

C2K Setting: ASCII CW Transmitted _ AA Traffic Handling Signal + AR Procedural Symbol_ $ SK Procedural Symbol ^ KN Procedural Symbol ? Question Mark . Period = BT / DN , Comma ; Semi-Colon : Colon

Note that the lack of a way to check if the radio is transmitting could cause issues with this CWBYCAT and AUTOCQ as we need to know when the rig is done sending.
##Xmit

Keying Command Format: *T1 to key the transmitter *T0 to unkey the transmitter.

##RIT Control
