UTC Radio Clock – AA0CN V1.0

AA0CN UTC Radio Clock

This is a printable clock face for 8″ analog clocks, with a fixed “Local” inner wheel and a rotatable “UTC” outer wheel. The outer wheel may be adjusted twice a year for Daylight Savings Time changes, or adjusted for time zone changes.

Inspiration was taken from maritime radio room clocks, with marked periods for 3 minutes after every 15 minute interval for distress silence, which also doubles as a marker for 3 minutes every 3 hours per ad-hoc radio schedules such as the 3-3-3 plan.


  1. Print out the two above linked PDFs at full size onto heavy cardstock paper.
  2. Cut away the gray sections of the Inner and Outer wheels, including the grey window box on the inner wheel so the current timezone is visible through the window when assembled.
  3. Remove battery and disassemble clock: Remove glass so face is accessible and remove clock hands.
  4. On both paper wheels, cut center hole for clock hand post to size.
  5. Insert the larger UTC wheel first, allow to rotate.
  6. Using double-sided tape, glue, or similar, affix the inner Local time wheel to the clock body through the hole of the outer UTC wheel, so the center is stuck down but the UTC wheel can still freely move. Remember to orient “12 O’Clock” to the top of the clock body!
  7. Replace hands back onto the clock. By placing them back into the “12:00” position, it is easy to get the hour/minute offset correct.
  8. Adjust the outer UTC wheel so current timezone is displayed through Local time window.
  9. Reassemble clock body, replace battery, and synchronize to WWV

KC0NPF’s Repeater Linking and D-star related link page

This is just a brain-dump of a lot of stuff I’ve been reasearching and poking around at recently. There’s a LOT of cool stuff in Ham Radio out there. I haven’t been on a ham radio binge this bad in a while 🙂

Reflectors, D-star, DMR, SIP bridges, all kinds of cool stuff in the following links:

  • [Streaming just about anything via Raspberry Pi](
  • [XReflector system]( Not currently used by the RARC but may be worth exploring in the future
  • [PAPA System of linked repeaters in California](
  • [All-Star Linking system based on Asterisk PBX and capable of linking just about anything](
  • [Peanut D-star application]( D-star from your mobile or PC WITHOUT an AMBE dongle, transcoding is provided by the service. Registration required for obvious reasons.
  • [ARDOP open packet protocol](
  • [Open P-25 project]( Decode P-25 systems like ARMER with software.
  • [Scanning P-25 with RTL-SDR](
  • [Winlink PAT on Raspberry Pi or other Linux PC](
