Live streaming local TV from Terremoto, Chile
According to Communications Quarterly news posted today, there are several frequencies being used in the amateur shortwave bands:
SSB frequencies: 10 meters – 28.300, 28.500 MHz 15 meters – 21.200, 21.350 MHz 20 meters – 14.200, 14.350 MHz 40 meters – 7.050, 7.095 MHz 80 meters – 3.738, 3.750 MHz (via CQ Public Service Editor Richard Fisher, KI6SN)
Chilean hams and emergency service agencies are asking that other amateurs keep these frequencies clear so that emergency communications are not impeded.
The communications on these frequencies may be difficult to hear on many radios because they’ll be using SSB, or single-sideband, a power-saving mode often used by hams to transmit longer distances using less power. These broadcasts will sound distorted on a regular shortwave radio, and require the use of a receiver that features SSB reception. I have such a radio, but in the RF interference zone of my Chicago apartment I’m having difficulty getting any clear reception.
I’ve been trying to hunt down some frequencies for Chile-based broadcast stations that use AM/normal mode on shortwave, but I am coming up empty. The only station I’m coming up with is Voice of Chile at 11,890 KHz listed at Radio Shack’s shortwave radio guide.
The National Hurricane Center is broadcasting tsunami updates at 14.300 MHz. I’m able to tune this in, but I’m getting too much interference to hear clearly. With luck people in Hawaii and elsewhere in the Pacific who need this information are receiving it better.
On the internet Ustream is offering a live stream of several local TV channels from Chile and Hawaii.
Thanks to NW7US and RadioGeek who have been providing emergency shortwave information on Twitter.
