[CW] Ship Radio Room clock

Sun Jan 9 12:24:14 EST 2022

For those who might wish to make their own Radio Room or Maritime Deck
Clock, here are some made by myself and Dan Zeitlan, K2YWE.

My files are PDF vector files which don't get jagged if resized and come in
red sector only, red and green sectors, and deck clock versions.

Red sectors were 500 kHz silence periods, green sectors were 2182 kHz
silence periods where stations were to NOT transmit and listen for SOS /
MAYDAY.

Patterns to make your own Maritime Radio Room 12 hour clock. Files from Dan
Zeitlan, K2YWE and David J. Ring, Jr., N1EA. N1EA's files are vector
artwork which can be opened in vector art program or PDF reader.

The K2YWE clock is sized in the pdf for the Ikea RUSCH clock, which is
currently 1.99 USD online. (Early 2018)

There is also a file called marclock.pdf which is a typical marine clock of
the same type as the Radio Room clock, but without the silent period
sectors of red, or red and green.  Use this if you just want a maritime
type clock.

enlarging.
