cable and refresh the COM ports again. Note the listed COM ports again. The one missing is
that of the USKI-5. Again, plug in the USKI-5 USB cable and refresh one more time. Select the
one for the USKI-
5. Then click on “Check PICAXE type connected”. If successful, a window will
appear indicating that “Firmware Check Successful”. If necessary, repeat the “Refresh COM
ports” and “Check PICAXE type connected” routines.
Open the desired USKI-5 program in the editor. Near the beginning of the program are lines for
specifying each START and STOP delay as shown below. Depending on the program, the
actual start and stop delays may be called “CW_START_DEL”,”PTT_START_DEL”, or
“TX_START_DEL”, for example.
It may be helpful to first fill out a timing delay work sheet shown in the notes section at the end
of this document.
Change the START and END values (in milliseconds, maximum
5
of 8191 ms) shown here within
the red blocks as necessary for each of the output channels.
In some cases, inverted or normally closed output may be desired on some channels (such as
for the mute function in many older receivers). This can be accomplished by simple changes in
the programs. Each program has an initialization routine that sets the outputs to their proper
states
upon power up. The default setting is open circuit which corresponds to a “low”
command. Changing any
“low” to “high” in the section indicated in red will initialize that output to
normally closed.

If delays longer than 8191 ms are required, refer to the addendum section at the end of this document.
