NAVTEX on 518khz

I don’t have the right antennas or the best setup for decoding, but I can still occasionally hear some of the more local NAVTEX stations, and using MultiPSK (capable, but man, is that one program in need of a makeover) I managed to decode some of the alerts. Without further ado:

Azimuthal Map Server

An azimuthal map shows the compass direction for the shortest path to a given location from the place the map is centered. This can be useful to help you aim antennas. I’ve used GMT to make maps before, but if you need a custom azimuthal map for your location, try surfing over to NA3T and NV3Z’s website, and make yourself one.

Here is the low resolution GIF image of mine, I downloaded a PDF that I printed on our ncie color printer.

You can see that Australia is mostly just south of west, Japan is northwest, and most of Europe is northeast. Interestingly, the tip of Africa is almost straight west, as is the panhandle of Florida.

WSPR on 15m today…

Today is Wednesday, which means that it’s a day for trying different bands on WSPR. Today is scheduled to be 15m, which I have never tried before. I immediately saw a few RTTY stations below the WSPR sub band, which was a good sign, and two minutes later, I had my first spot, and it was a good one: EA1FAQ in grid IN71op, in Central Spain. If you have the capabilities, tune your WSPR stations onto 15 and see what you can get!
