Repeaters – Waltham Amateur Radio Association

The Waltham ARA maintains four repeaters, all located on Prospect Hill in Waltham, MA. Our repeaters are open for use by all radio amateurs. All use the callsign W1MHL/R. On certain dates, one or more of our repeaters may be reserved exclusively for use by a public service event.

Repeaters

Note 1: The 146.64 MHz repeater has two special features:

It repeats both traditional analog FM and digital voice mode Apco P25. FM users can use 136.5 Hz Tone Squelch to mute digital voice “noise”. P25 users should select NAC 293.
EchoLink® is available on our 146.64 MHz repeater. Connect to us via W1MHL-R, Node 490278. To make outgoing connections over the air, touch-tone 64 and the Node number to connect, # to disconnect.

Note 2: The 927.1375 MHz repeater is linked full time via IRLP linking to the NEAR 900 Network. Our Current IRLP Status

NEVER ACKNOWLEDGE UNIDENTIFIED TRANSMISSIONS

Simple? Yes, but it’s often harder than you might think. It means that you do not say anything over the air that acknowledges that transmission.

·         Do not say “Did you hear that?”
·         Do not say “I couldn’t hear you because someone was throwing a carrier”
·         Do not complain about it.
·         Do not say ANYTHING that would tell the person that he is making it into the repeater.
