the professional and radio amateur.



The purpose of this event is to encourage the use of Amplitude Modulation on the Amateur Radio Bands, and to highlight various types of AM equipment in use today.  This event is open to any and all radio amateurs who are running full carrier amplitude modulation (standard AM), and any type of equipment may be used.


Commonly used AM Frequencies: 160 Meters: 1880-1885, 1930, 1945, 1975-1995.

80 Meters: 3730-3740, 3870-3885.  40 Meters: 7160, 7280-7295.  20 Meters: 14286.

15 Meters: 21425   10 Meters: 29000-29200.


These commonly used frequencies can be good starting points. As activity grows, expand to other frequencies to prevent congestion and excessively large round tables.  As always, PLEASE be considerate of existing QSOs and Nets, and ensure that the frequency is clear before calling “CQ, the A.M. Transmitter Rally”.


Points are to be awarded as follows:


a) 1 point for each station worked a specific band.  If you work the same station on more than one band, you get 1 point for each band.


b) 1 point for each state, country or Canadian Province worked.


Note: Both you and the station with whom you are QSOing must be using AM.


Logging: Note, the log format is the same as last year’s event. We also have free logging software.


The following information must be included in your log for each contact to be counted:


Time (local), Frequency, Call Sign, First Name, Their Location (city, state, country), Their Equipment.

Log Format: Each item should appear in a separate column, and in the column order shown below:






Logging Notes
: The CAT: line is the station category (a-g), and should be included in the first column (somewhere) if the station is to be entered in a particular category.  Example: CAT:A

Logging States and Countries:  The “State/Province” log column must contain the 2 letter state or Canadian province code unless the country is not Canada or the US.  In these instances, the 2 letter country code must be entered in the “Country” column.  We use software that reads the logs, and will look for 2 letter state and country codes, and add them into your score.


Free, simple logging software: We have created a free, simple to use logging program to facilitate logging for the A.M.T.R. and, if you wish, it will automatically upload your log to our logging server.  This program is available for free download. See


Using Excel for logging: Template logs are here: (excel) (csv).  Any program that can generate a comma separated values file in the order shown in the logging example may be used.

à Please let us know about anything outstanding, unusual or unique you hear.


A description of your station equipment, power and any other interesting features should also be included as part of your submission along with your mailing and email addresses.  Pictures may also be emailed to us.


If at all possible, please use electronic submission of logs using our Logging program, Excel or CSV (comma separated values) formats.  Email Excel or CSV logs to:


If you do not own, or cannot use a computer, paper logs may be mailed to: Radio Engineering Associates
