Monitoring Maritime Radio Messages with YADD<\/h1>\n

\"\"<\/a>This is really cool and very easy.\u00a0 Easy nerd thrills.<\/p>\n

On Friday, Steve VE7SL,\u00a0put up a blog post<\/a>\u00a0on how we can relive the glories of our youth by monitoring HF long-distance maritime traffic.\u00a0 In the old days the ships were on CW and many report that it was great fun to listen to the various “fists” in action from coastal stations, and from ships on the high seas.\u00a0 While the CW is long gone, this maritime traffic is still on the air.\u00a0 Today they are using a SEL call system called\u00a0Digital Selective Calling or DSC.\u00a0\u00a0<\/a><\/p>\n

Happily, it is very easy to decode these transmissions.\u00a0 Steve recommends a program called YADD (Yet Another DSC Decoder).\u00a0 I downloaded it in seconds and had it installed on my computer in minutes.\u00a0 Next I had to find a general coverage receiver.\u00a0 I thought about pressing my old HQ-100 into service, or maybe even the S-38E, but a cooler head prevailed.\u00a0 I remembered that Farhan had given us a general coverage receiver in his uBITX transceiver.\u00a0 So it came off the shelf and got powered up.\u00a0 Around dawn on October 14, 2024 I put the receiver on 8.415 MHz LSB.\u00a0 I didn’t even have to do a real connection to the computer — I just put the speaker close to the mic and that was sufficient.<\/p>\n

Boom.\u00a0 Soon I was getting signals from ships afloat and from coastal stations.\u00a0 I heard Shanghai, New Zealand, and Australia.\u00a0 \u00a0See above.\u00a0 \u00a0From the U.S., I heard Miami, but the most emotional for me was hearing the station at Pt. Reyes, in California.\u00a0 This is the station that Dick Dilman W6AWO has volunteered at for many years.\u00a0 FB.<\/p>\n

Back in 2017, Steve had another post on DSC and YADD:

Thanks Steve!<\/p>\n

This site explains very well what DSC is.\u00a0 From this I think we can see that there is nothing illegal about using YADD to monitor the DSC alerts (that are all emergency-related):\u00a0\u00a0https:\/\/infoshipping.tripod.com\/gmdss_dsc.html<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
