There are several ham radio applications that, when they startup, have the ability to start other programs as well. Some examples
are fldigi and wsjt-x. Several people have found this to be a convenient way to keep their radio's clock synchronized
by running set-7300clock as an autostart application. Both the PowerShell and C# versions of set-7300clock were
originally intended to be used stand alone or to serve as examples, so neither of them include very robust error
checking, collision detection, or retry attempts. Thses features become very important when multiple applications
are communicating with the radio over the CI-V bus at the same time or with shared serial ports. So that people can use set-7300clock in
conjunction with other CI-V programs, I have modified the command line program to share the same CI-V communication
code used by ICOM 7300 Memory Manager, which does include all of the features mentioned above.
This updated version of set-7300clock can be used as an autostart program with other application such as fldigi or
wsjt-x. The program works in the same way as the prior version, but the command line options have changed slightly.
I have switched to using the Microsoft System.Commandline library for parsing the command line which makes that job
much easier. However, it also required me to change how some of the options are specified on the command line.
Here are the command line options for set-7300clock
Set the internal clock on selected ICOM radios. The source for the time can be the computer's clock or an NTP server. There are options
to use UTC vs. local time, set the clock immediately without waiting for the seconds to roll over to the next minute, suppress console
output, and to set communication parameters.
-p, --port <COM10|COM5|COM7|COM8|COM9> (REQUIRED) The COM port connected to the radio.
-b, --baud <115200|19200|38400|4800|57600|9600> The baud rate to use to communicate with the radio [default: 115200]
-t, --timeout <timeout> Timeout for reads im milliseconds [default: 1000]
-q, --quiet Don't display prompts to the console [default: False]
-i, --immediate Set clock immediately without waiting for the seconds to become zero [default:
-u, --utc Use UTC time rather than local time [default: False]
-m, --model <ICOM705|ICOM7300|ICOM7610|ICOM9700> The model of ICOM radio [default: ICOM7300]
-a, --address <address> The CI-V address of the ICOM radio. Default is based on radio model (IC7300
shown). Use this if you have changed the CI-V address in the radio from the
default [default: 148]
-s, --server <server> An optional NTP server to use as the source for the current time. If contacting
the server fails the program will not set the clock unless the --fallback option
is set to true. [default: None]
-f, --fallback When contacting the NTP server fails, fallback to using the system clock. Used in
conjunction with the --server option [default: False]
-d, --debug <Debug|Information|None|Verbose|Warning> Turn on debug logging. Order of severity is None, Warning, Information, Debug,
Verbose. [default: None]
--version Show version information
-?, -h, --help Show help and usage information
An example command is:
set-7300clock --port comport --baud baudrate
or alternatively you can use
set-7300clock -p comport -b baudrate
There are some changes in options and option handling that I need to discuss here.
- The System.Commandline library uses "--" rather than "-" to specify command line options. Since
the library enforces that convention by default I have followed it. However I have defined an alias
for most of the commands that uses "-" in addition to "--". So you should be able to use either
way to specify command line options.
In previous versions of set-7300clock, you could specify the COM port and baud rate by position
in the command line. This new version requires that you use -p or --port to specify the port and -b
or --baud to optionally specify the baud rate. The only required option is the COM port, which must be
specified in all upper case.
Previously you could use:
set-7300clock COM1 115200
Now you have to specify them as follows:
set-7300clock -p COM1 -b 115200
There are several new options:
- The timeout option permits you to specify the number of milliseconds before a timeout occurs
when waiting for a response from the radio. The prior default was 500 milliseconds, but it proved to be advantageous
to permit adjusting this on some slower systems or those using virtual COM ports. I also changed the default to
- The quiet option causes all routine prompts and messages coming from the program
to be suppressed. Error messages will still be displayed. If you specify the --quiet option
without the --immediate option the program will still wait for the clock to roll over to the next
minute. However you will not receive any feedback regarding how long the program needs to wait
for that roll over to occur. When this happens it might appear that the program is hung or stuck, but
it is just waiting for the seconds to roll over to the next minute.
- The immediate option was suggested to me by SA7CND Poul. If this option is specified
the program will not wait for the time to roll over to the next minute. Instead, the program will
immediately set the clock to the current minute if seconds are less than 30, or the current minute + 1
if seconds are greater than or equal to 30. The clock will still be within 30 seconds of the current time
and there will be no delay while the program waits for the time to roll over to the next minute
For example, if the current time is 08:34:15 and the immediate options is specified, the clock will
be set to 08:34. However, if the current time is 08:34:42 and the immediate option is specified, the clock
will be set to 08:35.
Note: This option does take into account the possibility that adding one minute to the current time will
potentially change the hour, day, month, or year when setting the clock.
- The server option lets you specify an NTP server to use as the source for the current time.
If the program is unable to contact the server the clock is not set unless you specify the fallback option.
In that case the program will use the computer's clock.
- The fallback option is used in conjunction with the server option. When the program is unable to
contact the specified NTP server, the fallback option will have the program set the time to the computer's clock.
- The help option displays the description, usage, and options information shown above.
- The version option displays the version number of this program.
- The address option is useful when you have changed the CI-V address in the radio from the default.
You can specify the address in decimal or hexadecimal.
- The model option lets you select the model of ICOM radio. Currently the 7300, 7610, 705 and 9700 are supported.
- The debug option is for use in debugging the program if things go wrong. Hopefully it won't be needed very often.
I will continue to provide the example C# source code I had posted previously although it no longer matches the
actual set-7300clock program.
