[UPDATED to correct event times and dates 2017-01-30 @ 1350 UTC] US and Canadian radio amateurs and Part 5 Experimental stations will take part in the second annual Midwinter 630-Meter Activity Night, which will get under way on February 5 at 0000 UTC (Saturday, February 4, in US time zones) and continue through 2359 UTC. Radio amateurs in the US will be able to make cross-band contacts with Canadian participants.

“This event is being undertaken because of the continuing, worldwide interest in 630 meter activities,” said ARRL 630 Meter Experiment Coordinator Fritz Raab, W1FR, in announcing the event. He said US radio amateurs are looking forward to gaining access to the new 472-479 kHz band, while Canadians are eager to learn more about the present level of amateur activity on their newest ham band.

“This activity night will give interested radio amateurs in both countries, an opportunity to see firsthand what is happening, and cross-band activity with Canadian amateurs will offer a chance for US hams to take part in the activity,” Raab said.

The event is open to both radio amateurs and listeners. Raab said it will provide an opportunity for participants to test their MF receive capabilities. Operation will be in various modes.

These Canadian stations have indicated that they will be on the for the event on CW, transmitting on 630 meters and listening (QSX) on US Amateur Radio bands.

“The success of this event largely depends upon the participation of as many amateurs as possible,” Raab said.
