I know, I know you don’t need this. You run your very own local GPS-synced Stratum 1 NTP server, probably on a Raspberry Pi…

But other ICOM users might be interested to discover that the company has released ST-4003W, a Windows application that permits setting transceiver time from your PC’s time.

Compatible radios (as of November 2021):

  • IC-705
  • IC-7100
  • IC-7300
  • IC-7600
  • IC-7610
  • IC-7850/IC-7851
  • IC-9700

Usual caveats; RTFM before installing, don’t tug on Superman’s cape or spit into the wind, etc. etc.
