CAT answer on ZZFB; command with Slice A only

Sergey R5AU

What the CAT answer should be on ZZFB; command with Slice A only  - one Pan one Slice
today it looks like (SSDR 2.1.33) :


5A 5A 46 42 3B              ZZFB;
       22:46:42 PM Read: 
3F 3B                       ?;


but  questionmark " ? "  is not documented in CAT User Guide with ZZFB command
What should be "as designed" ?

The CAT commands are Kenwood CAT based. Therefore the Error Codes are as follows:

■ Error Messages

In addition to the Answer command, the transceiver

can send the error messages listed below

Error
Message Reason for Error

?;

•Command syntax was incorrect.

•Command was not executed due to

the current status of the transceiver

(even though the command syntax

was correct).

Note: Occasionally, this message may not

appear due to microprocessor transients in

the transceiver.

E;

A communication error occurred, such

as an overrun or framing error during a

serial data transmission.

O; Receive data was sent but processing

was not completed.

The ZZFB; command returns the frequency for VFO B in the format listed in the Flex Cat Manual. If you have 1 Panadapter and 1 Slice but do not have VFO B Active and selected it would explain why you received the Error indication.

Thank you Wayne, probably i missed original Kenwood explanation : 

•Command was not executed due to

the current status of the transceiver

(even though the command syntax

was correct).

What is right in my case.

The "?" means the command was not understood or it is not applicable for the slice it was sent to.

All VFO "B" commands will return a "?" unless the radio has been put into SPLIT mode by issuing the ZZSW1: command.  When in split mode, the radio automatically create the VFO B slice (you cannot create it manually).  And all VFO B CAT commands sent to the VFO A (parent) slice will respond appropriately. 

Programs that support split only have one CAT port, so both VFO A and VFO B CAT commands are sent to one and only one CAT port.  

To take the radio out of split, issue the ZZSW0; command.
