hypothetically two ways to get frequency data faster. The external
software (e.g., CT) could be told to poll the transceiver more often,
sending it the FA and FB commands, which return the frequency of the A and
B VFOs. Alternatively, sending the command AI2 at startup will cause the
radio to output changes in frequency and some other parameters "when they
change."
This is from the command summary in the TS-570 manual on the Kenwood web
site, and there are some key points missing -- for example, how quickly
does a given radio respond to frequency queries, and how quickly does the
radio, on its own, decide to report that the frequency has changed. There
might be practical upper limits on how quickly a given radio will respond.
If anyone is interested in experimenting, because Kenwood uses a simple
ASCII command set you can use Hyperterminal to talk to the radio and see
how it responds. You just set Hyperterminal to talk to the appropriate COM
port with the right parameters, and you and your radio can have a nice chat.
