Communicating when the Worst Happens

I've been told the two key things to manage in the event of a disaster are communications and logistics. Ham Radio Operators are very well practiced in the Communications site, and in fact, often run the communications systems for public events, as a practice for when it is required for a real emergency. Thus, with your Amateur Radio License, you can help out with such events in a very real way, assisting to save lives!

Preparing for a Lack of Phones

In today's busy world, in constant communication, it seems like cell phones are available everywhere. The truth is, they are highly available, but they do have their issues, whether climbing mountains, major disasters, or traveling to remote areas, there will be a time where you don't have constant communications with the world through phones and cell phones. What do you do then?

Figuring out the Master Band Plan

Now that I've started to go digital, one of the key things is to figure out the digital band plan. I have plans to eventually do something really neat with this, but here's a rough idea of what the band plan is for Digital modes. I'm going to focus on 20m, as most of them are similar to it, and include the links for the other information.

At the highest level is the FCC rules:

14.000-14.150 MHz- Digital Modes (CW included)
14.150-14.350 MHz- Analog Modes (SSB included)

The next level seems to be the ARRL band plans, which are actually quite complete for VHF+, but seem to lack a bit in the details for HF bands:

20 Meters (14.0-14.35 MHz)

14.070-14.095 RTTY
14.095-14.0995 Packet
14.100 NCDXF Beacons
14.1005-14.112 Packet
14.230 SSTV
14.286 AM calling frequency

The next level down is CIARC, which provides some really good detailed information on digital modes, but is still a bit lacking.


Mode Specific Dial Freq Center Freq Offset
PSK31
14.07 14.07015
Olivia Olivia 16/500 14.073.65 14.0744 750
Olivia Olivia 32/1000 14.1055 14.1065 1000
JT65
14.076

Olivia Olivia 16/500 14.07765 14.0784
Olivia Olivia 32/1000 14.1055 14.1065
Olivia Olivia 32/1000 14.1065 14.1075

The ultimate band plan seems to be bandplan.com, but this has a bit too much detail, including nets, etc.

I'm going to put together a master band plan, that includes everything I can find, and piece it together here. Hopefully it will be of some use to the community out there!

Working JT9/JT65

In my working with digital modes, I have started with JT9/JT65. I've found them to be rather relaxing modes, you can easily do something else while you are talking, and just get back to the conversation every two minutes. I'm hoping to give a bit of an idea of how these two modes work, and what should be done to improve communications on the subject.

Mobile setup

One of the things I noticed early on about 2m is that the majority of the people using it seem to be traveling when they are using it, except for things like nets. After a while, I started to wonder how I could get involved with the same thing. Eventually, I got my set up figured out, and let me explain it here, along with some of my future goals in the matter.
