The Amplitude Modulation Amateur Radio Society

A home for radio amateurs who enjoy amplitude modulation: the original voice mode, still full of warmth, character and technical interest.

Welcome

What is AMARS?

AMARS exists for operators who enjoy the sound, technique and tradition of amplitude modulation.

The society encourages friendly contacts, practical experimentation, restoration of classic equipment and the continued use of AM on the amateur bands.

GX5AMS

The society callsign gives members a shared identity for events, demonstrations and club activity.

Last year we had GX5AMS on the air from the National Hamfest in Newark.

Community

On the air:
Back on Top Band!

The AMARS Top Band Challenge, getting back on Top Band for a chat. Nothing formal, it's not a contest.

It's just an opportunity, at times when you know there will be others around, to enjoy a relaxed QSO in an old-fashioned way.

Every day Monday 28 September through to Friday 2 October 2026
2000 - 2100 BST

Operating

Amplitude modulation: the original voice mode

AM has a distinctive presence on the bands. It invites careful adjustment, good audio practice and a slightly more deliberate style of operating. The result is a mode with technical depth and real personality.

This area can later hold recommended frequencies, net times, band plans, operating guidance and links to useful technical notes.

Technical interest

Transmitters, receivers, modulation depth, audio chain, antennas and operating technique all matter on AM.

Heritage

AM connects today’s amateur operators with the earliest years of voice communication by radio.
