Maritime Radio Day, April 14-15, 2018

“Whitey” Doherty, K1VV writes:

Maritime Radio Day is held annually to remember the nearly 90 years of wireless service for seafarers. Since its beginning in 1900, Maritime Radio was in use mainly until the end of 1999.

The MRD is open to all Amateur Radio Stations. Special stations (like Coastal radios and ship’s call signs) can participate to the MRD only if operated by former Commercial or Navy operators, or by radio technicians who worked in the installation and/or maintenance of naval equipments.

If you are a former Merchant Marine Radio Operator or former ship’s Electronic Technician please subscribe to this event automatically trough the following website or by communicating your Amateur Radio callsign and last ship of last coast radio you served to R/O Rolf Marschner at:

We must to push many colleagues to take part at our yearly Event, last year like in the past edition there has been a massive participation with many colleagues not included in the list of participants and it has been a very nice surprise against any prevision. There are still many Countries not reached by information about our Event and from U.S.A. and Far East – Unfortunately – still very few stations. Radio Officers are the men spent their lives in front a receiver watching 500 kHz and sending messages of any kind, our Category has gone but we know many aspects of radio waves and we cannot refuse to look forward to confirm the radio is still alive and in good health, the problem perhaps is another, there are many reasons to kill the radio and they are not properly justified by true facts but only using the famous word “OBSOLETE” we hear everyday and everywhere for promoting the consumption of technological toys such as Smartphones, iPhones, Tablets and so on.

Morse Code, the main language used by Radio Officers on ships and at shore, has been the sole international language that granted for a century radio communications at sea, nowadays used by many amateurs radio needs to be protected against the interference due to Hi-tech products and web communications, the Radio World is made at first of Morse communications and the code is easy to learn also if the tendency is to send and receive Morse with computer… the worst way to take practice of the code, the code is not a digital mode it is a “very special human way” to establish a communication between two points of the earth with no wires and no computer, just a small, old and used radio and a wire dipole or at least a piece of wire.

Rules, Procedure and Certificate of partecipation

All traffic must to be done around the following International Naval Frequencies on Amateur Radio Bands (morse code)

1824 kHz

3520 kHz

7020 kHz

10118 kHz

14052 kHz

21052 kHz

28052 kHz

The Main working frequency is 14052 kHz plus or minus some kc/s. The WARC bands are NOT USED for MRD with exception of 30 meters band.

To give everyone a fair chance of having a QSO during the MRD, and because 14052 kHz is the most common calling frequency, it is suggested that we have a small band edge from 14055 to 14058 kHz  for DX and QRP stations. It is also suggested that instead of calling CQ in “Contest Mode”, we give adequate time for weaker stations to be heard and listen  especially for DX contacts.
So please use the band suggested as watching band reserved to radio stations in far distances.
