Cheers
Forgot to mention for anyone exploring EasyPal..if it is indeed decoding, apart from ALL the green "traffic lights" being on there will be a green bar following the progression of decoding. This green bar resembles the progress of a file being downloaded, and is to be found right under the "waterfall".
73 good dxing

Thanks for the frequencies SV1BTL and others.
What we now need is what programs we decode them with, preferably freeware, and a nice writeup (like the one on EasyPal the other day) on the nitty gritty.
Anyone who has the time...and the will ...would be nice.
Thanks

Hi SV1BTL
Thanks for the frequencies, will definitely start working on them :}
Maybe if it is possible some of the info here could be sorted out and added to the Digital Dx page under information in "Global Tuners "
There have been so many wonderful posts here, I think it would be a shame to loose them.
Regards
gypsy.

Hi all,

You can find a big collection of software in Internet. Try to search "digital amateur" in Google. I personally use Ham Radio Deluxe (freeware - http://www.ham-radio-deluxe.com/ dedicated for controling ham equipments, but it includes digital modes decoders as well) and MixW (http://www.mixw.net/ not freeware ~50$, but very capable in decoding almost everything).

EasyPal (for digital SSTV) can be loaded here: http://dc140.4shared.com/download/123029716/42ac37a8/EasyPal-31-JUL-2009__Digital_SSTV_.exe

Digital Voice modes (FDMDV, WinDRM, DRMDV) can be loaded here: http://dc105.4shared.com/download/114569603/c47a964f/Digital_Voice_Amateur__DRMDV_FDMDV_WinDRM_.zip

A big variety of links and software can you find here: http://www.muenster.de/~welp/sb.htm and here: http://www.rv3apm.com/

and finaly two sites that offer audio examples of digital modes: http://www.kb9ukd.com/digital/
http://www.wb8nut.com/digital.html

Enjoy, 73 de SV1BTL (Emmanuel)

Nice thread this one! Juicy stuff pops up, and we all complement our knowledge by sharing it at this Forum!

One thing about endless lists of programs, however..maybe I am wrong..dont know..or I may have just been unlucky:

problem with "Jacks of all trades" software OR programs found by just doing Google searches is that software that tries and does it all, does a bit of this and that but not a good enough job.

Say Mixw, or MultiPSK etc. Try and decode for example SITOR or PSK with one of these ambitious do-it-all packages.

Then get one dedicated software, say DigiPan (for PSK), or Frisnit (for Sitor). Decode again and compare time required, breadth and accuracy of results.
Both are free.

In a nutshell? Maybe tried and tested specialized software along with some basic working-tips can help users of the site take off faster.

An A/B Frisnit vs MultiPSK, will demostrate the difference.

EasyPal is specialized in doing one thing and (as others have already pointed out in this thread) it does one thing and it does it very well.

The links for audio files of various digimode examples (kb9ukd and wb8nut)is a GREAT idea, I hope many of our users make use of them!

Certainly more convenient than browsing YouTube, which nevertheless has nice tutorials on modes and their operation.

Let me add one more GREAT link for signal analysis I found at Norave's (aka DK1NY, Sven) site: http://qrg.dk1ny.ath.cx/links.php and then http://signals-analysis.blogspot.com/

Also, on the same subject, don't miss giving "Spectrum Lab" (1) a close look, which apart from being soundcard compatible is interstingly directly compatible to: 1) Perseus, 2) RFSpace SDRIQ!

It's a tool that (among other things, see link at end of this message) allows us to do the very signal analysis ourselves and come to conclusions about shift, spacing etc.
It's free and also works with Vista too.

Will be exciting to see specialized software for specific modes plus a write up of basic tips, some of us know lots and we can help our mates, who will help others in turn, get more people attracted to (ham or other)radio.


(1) Spectrum Lab and its detailed description can also be found at:

4BH 882 kHz ("The Best songs of all time", Brisbane, Australia) is going DIGITAL, DAB+. [UK is still DAB].

DAB+ is interesting in that apart from the stellar clarity of audio it provides, it can also simulcast AM and FM programs. DAB+ is also considered to be intergrated into "set top boxes" for digi-TV and car radios either via SatNav or adapters.

Hi Tim
Thanks for the interesting bit of information on DAB+ in Australia and 4BH in particular.
Australia has indeed gone in a big way with digital broadcasts, hope India follows suite early.

Hi
[HCDX] Launch of HCJB/IBB DRM trial broadcasts on August 17

The HCJB Global Technology Center, based in Elkhart, IN, USA in cooperation
with the International Broadcasting Bureau, will begin a series of digital
broadcast test transmissions on shortwave starting on August 17. The
demonstration broadcasts are using IBB transmission facilities on the east
coast of the USA and a DRM exciter and content server developed by the HCJB
Global Technology Center. The broadcasts are operating at an average DRM
power of approximately 8 kW using a rhombic antenna aimed at 45 degrees on
15475 kHz from 2000 to 2200 UTC for reception in Europe and a log periodic
antenna aimed at 306 degrees on 9405 kHz from 0000 to 0400 UTC for reception
in North America. The broadcasts are expected to continue for at least
several weeks. Reception reports can be emailed to ibbhcjb@gmail.com
Please visit www.hcjb.org/tech for more information on the work of the HCJB
Global Technology Center.
Thanks to alokesh gupta for this information
Regards
Gypsy
