Maintenance Note: Power supply change

IC-7200

Some users have had issues with spontaneous shutdown of the IC-7200 on voice peaks, especially with the COMP enabled.  This morning the aging Astron RS-20 power supply was switched out in favor of an SEC-1223 switching supply, which will provide adequate power on peaks to avoid shutdown.

When the rig spontaneously shuts down, the USB connection to the host computer is broken momentarily before the IC-7200 restarts.  On restart of the radio, the USB connection is NOT automatically reestablished.  This results in the station going offline until manual intervention by the admin is performed.  The host software will “hang” and must be manually halted with the Windows Task Manager, then restarted.  On restart the USB connection to the radio is then properly reestablished and the station is back on line.

It is easy to see why we want to avoid this problem!  Please report issues to me via email.
