Ενημέρωση από την Ένωση Ελλήνων Ραδιοερασιτεχνών

DSD 1.7 για Windows

Το DSD είιναι μια εφαρμογή που μπορεί να αποκωδικοποιήσει την ψηφιακή φωνή του D-STAR (και όχι μόνο) χρησιμοποιώντας ένα rtl-SDR dongle σαν δέκτη σε ένα υπολογιστή με Windows. Για να γίνει αυτό συνδέουμε τον υπολογιστή με τα Windows και τον δέκτη μέσω του φυσικού καλωδίου του ήχου (sound card) σε ένα δεύτερο υπολογιστή με λειτουργικό Linux και το πρόγραμμα DSD 1.7 (Digital sound decoder). 

To DSD υπάρχει και σαν εκτελέσιμο αρχείο στα Windows οπότε μας χρειάζεται τελικά ένας μόνο υπολογιστής. Σαν δέκτη μπορούμε να χρησιμοποιήσουμε εκτός από το rtl-SDR dongle, οποιονδήποτε άλλο ραδιοερασιτεχνικό πομποδέκτη που ακούει σε FM.

Τα βήματα που χρησιμοποιήθηκαν για το όλο εγχείρημα είναι αναλυτικά τα εξής:

Συνδέστε την ακουστική έξοδο του δέκτη σετην είσοδο του μικροφώνου του υπολογιστή σας. Αν μπορείτε να χρησιμοποιήσετε την έξοδο από τον πομποδέκτη που χρησιμοποιείται για packet 9600 (βύσμα ps2 6 ακίδων) ακόμα καλύτερα θα χρειαστεί όμως ενδεχομένως να ρυθμίσετε το gain της βαθμίδας είτε από τον πομποδέκτη η από τον υπολογιστή λίγο παραπάνω.

 1. Κατεβάστε το αρχείο Zip για dsd-1.7.0 από τις ιστοσελίδες της Ένωσης Ελλήνων Ραδιοερασιτεχνών και τα χρήσιμα αρχεία στην πρώτη σελίδα η από τον σύνδεσμο εδώ: http://www.raag.org/LH2UpLoads/ItemsContent/770/770.zip

2. Αποσυμπιέστε το σε ένα folder στον δίσκο σας πχ στο C:\DSD

3. Ανοίξτε ένα παράθυρο σε DOS από το start->run πληκτρολογήστε cmd και Enter η OK

4. Στο παράθυρο που έχει ανοίξει πληκτρολογήστε CD \DSD για να μεταφερθείτε στο subdirectory C:\DSD

5. Για την αποκωδικοποίηση του D-Star, πληκτρολογήστε: dsd -i /dev/dsp -o /dev/dsp -fd

6. Μόλις υπάρξει δραστηριότητα στην συχνότητα που ακούτε θα δείτε τα header στην οθόνη και θα ακούσετε τον ήχο από την κάρτα ήχου.

Με την ίδια τεχνική μπορείτε να αποκωδικοποιήσετε και άλλα ψηφιακά πρωτόκολλά όπως για παράδειγμα το DMR, MOTOTRBO, P25, C4FM κιλπ.

Πληκτρολογήστε dsdhelp για να δείτε τις δυνατότητες.

Σας εύχομαι καλή επιτυχία, 73!

JH1AJT on SV2ASP/A Mount Athos

Mount Athos update:  SV1DPI, Kostas, says, "We tried hard to repair the antenna.  We sent a new controller to Monk Apollo and he changed it.  Unfortunately, the SteppIR doesn't operate as it should.  It seems to have an SWR about 2:1 and the signals are not as strong as they should be."  After many tries, "Zorro" talked to the SteppIR company and they sent a new antenna out, no charge.  Zorro himself paid for the shipping, new control cable and new 40M kit.  The new antenna arrived at Greek Customs a few days ago and is expected to be in Mount Athos at the end of the week.  Kostas and a few friends will install the new antenna, hoping all the problems go away.
 
April 26th, 1730Z.  Just got off the phone with Zorro from Mount Athos.  Here is some information he requested I forward to the Ham Radio community:
Zorro's Greek work team has returned home.  He is alone on Mount Athos until his scheduled departure on Monday, April 28th.  Monk Apollo returned to Mount Athos today and they had a very good meeting.  Zorro and his team were able to install a new tower, but the SteppIR antenna is still broken.  There are two issues with the antenna.  One is the SteppIR motor is intermittent, the other is the Control Box is not functioning properly.  Zorro could not get the SteppIR to work as it should.  More repairs will be required.  In the meantime, he hung a 15 & 20 Meter dipole from the tower.
Monk Apollo plans to operate Sunday morning (April 27th) with Zorro at his side from around 0800/0900Z for one hour or so.  Frequency unknown.  This is all the time Elder Apollo has for radio operations as he is busy with his duties on Mount Athos.  As far as Zorro operating alone from Mount Athos while Monk Apollo is tasked, that is not a decision that can be made by Monk Apollo or Zorro.  There is a 20 Monk committee that must approve any and all communications operations.  14 of 20 committee votes are needed to allow any such endeavor.  Monk Apollo is all for furthering the hobby from Mount Athos, but it is not his decision.
- END -
Now, here's a few of my comments. Of note, and just as in Myanmar (which took ten visits and numerous communications between Zorro and Myanmar officials), Zorro has opened a solid line of communication for future radio operations from Mount Athos.  Zorro worked long and hard to open up Ham Radio into Myanmar, and he's ready, willing and able to work long and hard to further the hobby on Mount Athos too.
I did not know (until today) that there's a committee that overseas radio/communications operations on Mount Athos.  I, like many Hams I've spoken to always thought radio was controlled by one man.  It is not.  I learned that Monk Apollo is a very, very busy man tasked with many duties.  Elder Apollo wears many different hats in support of the Orthodox Spiritual Center.
