Navtex And Console

rmrrgs
Hi,
Anyone using Console to pull in Navtex (518 KHz) broadcasts directly ? If so, directly via Console, or going to a secondary program like YAND ? How ? I live about 20 miles due West of Boston, and using my R8600 with Yand, cannot receive anything, ever, am or pm. Hoping with Console, I can do better. Thanks, Bob |

I used console with Virtual Audio Cable and put the audio into YAND and it seemed to work for me in Indiana. I know the navtex works on a schedule which I think is a part of YAND. I’m not at home right now to look at my setup but I’m sure that’s how I had it

well I cant take a screen shot of it right now because I have so much noise that I cant get a signal, Itll probably go away later but heres a tutorial I found. It shows them setting it up with sdr_uno but its pretty much the same for console https://www.rtl-sdr.com/tag/yand/

Hi Bob,
I’m not aware of any plugins or utility within SDR Console that will allow direct decoding of NAVTEX. For that matter, I ‘m not aware of any NAVTEX plugins for any of the other popular SDR programs (e.g., SDRSharp, SDR++, HDSDR, SDRUno).
Your best bet will be to use YaND and install a virtual audio cable program to “pipe” the audio from SDR Console into YaND. Actually, any software program that can decode SITOR-B (Simplex Teletype Over Radio) will produce decoding and display of the messages. Some candidate software product are MultiPSK and fldigi. Like YaND, you have to “pipe” the audio from the SDR software program into the digital decoder program. Here’s a link to various NAVTEX decoders:

YaND is by far the more elegant program for decoding NAVTEX. Although the others will produce text, that’s all you get. The beauty of YaND is it contains all of the information about the NAVTEX stations across the world, logging capabilities, and more. The other programs will just give you a readout of the decoded text. YaND is my go-to program for decoding NAVTEX. Also, with a good virtual audio program, you can “pipe” the audio into different software decoders at the same time. I’ve done so with YaND and fldigi, as there have been a few times when fldigi seems to handle noise a little better and produced better decodes in certain situations. Having said that I still use YaND for 95% of my NAVTEX decoding.
Good luck with your efforts. I know you’ve been experiencing problems getting the Boston NAVTEX station (actually on Cape Cod) directly with your Icom R8600, so until you solve your antenna and/or RFI noise problems, I don’t think YaND or any other software program will provide you a success path for NAVTEX reception.

There is this project by Jan van Katwijk: https://github.com/JvanKatwijk/SDRunoPlugin_navtex I've tried it but had no success with it. |

Bob. Let me guess. You're using the 8600 with the AD-55NS power supply? I may be wrong. You're using non-ferrite bead USB cables. Again am I right or wrong? Try cranking the RF gain down from 100%. Until around 518 kHz the waterfall cleans up. And the REF setting will help clean up the visual display on the radio too. Yand is ok. Fldigi works good too if you setup the data directories as in the help files. |
