  • do u use am or fm on the radio you connect to the computer?

  • @radiosification Most signals, If not all P25 signals are FM.

  • Wow awesome video. Can you help me with some links, or any other information on this. I live in the UK and we have so much D-STAR MortoTRBO radios over here at the moment. I have a tap fitted to my scanner.... I have ubuntu, but I'm new to Linux! Where do I get the DSD software, how do I install it..... Just a big idiots guide on the whole thing would be great. Can you help me please?

    Thanks

  • @TheNetHasEyes1 Not sure about D-Star as "DSD" does not decode D-Star (yet??) You can get a DV dongle for that purpose. IIRC DSD does MortoTRBO but I have not yet decoded any of those because I don't think there are any of those systems around my location. As for installing DSD, I learned what I need to know from the website listed in the info and at my website

see all

  • @jbail All P25 signals are 12.5 kHz narrowband signals.

  • It is possible to port DSD into Windows.. main changes or patches will be the sound card drivers

  • btw you can run this on windows now!

  • great video this is really interesting

  • Cool. I'll have to give this a try sometime!

  • DeathStar is crap anyhow. Forget about it. P25 is a better option until Codec2 comes into play for Ham Radio. .-.-.

  • thanks for sharing. Nice website as well

    great field day this year with W1NY...
