OK and what is the freq for 6m WSJT? orrin wn1z On 5/22/07, Tony [EMAIL PROTECTED] wrote: I was under the mistaken impression that MS is used only during the big meteor storms. Definitely worth looking into now. Orrin WN1Z Orrin, It's a lot of fun to work VHF during the major showers. The ionized trails will usually last long enough to get a few words in on SSB. The daily sporadics are more challenging since the reflections are much shorter and weaker. The six meter band is a good place to start and it doesn't hurt to operate during the AM peak.

OK and what is the freq for 6m WSJT? orrin wn1z Orrin, The calling frequency is 50.260, but it's best to set-up a sked with someone on the Ping Jockey page; http://www.pingjockey.net/cgi-bin/pingtalk the majority of QSO's are made this way. Once logged onto PJ, click USER DETAILS and enter your info. Setting up a sked is as easy as asking someone to run with you. Let the person know what mode and frequency you'd like to try and if you will be transmiting first or second sequence (see TX FIST box in WSJT). The maximum distance for meteor scatter is about 1300 miles. Enter the grid square of the station you'd like to work in WJST's grid-box to find the distance. You can work stations via meteor scatter that are close-in; about 250 miles. A small Yagi and 100 watts will do on 6 meters... Good luck... Tony KT2Q

Re: [digitalradio] Meteor Scatter Basics
Jose, I used Audacity audio editor, which plays the files and lets you see simultaneously the wave stream. I agree, it's interesting to listen to and to see the radio meteor spectral signature with an audio editor. I've been using CoolEdit96 for years and it is possible to capture the doppler caused by the head of the meteor if it's large enough (see attached). Tony KT2Q attachment: Doppler.jpg
Re: [digitalradio] Meteor Scatter Basics
Tony, Thank you for the basics tutorial. I would like to comment that those who downloaded the WSJT example audio files may use them to experiment what is heard. I used Audacity, a free audio editor, which plays the files and lets you see simultaneously the wave stream. It is interesting to hear the sounds and see the amplitude envelope simultaneously. I used that method when playing the FSK441 and JT6M examples, and I found it quite enlightening to compare what WSJT shows with what Audacity plays and displays. I could not play both simultaneously, but found interesting to relate the envelope with the display in WSJT 5.9.7 73, Jose, CO2JA __ V Conferencia Internacional de Energía Renovable, Ahorro de Energía y Educación Energética. 22 al 25 de mayo de 2007 Palacio de las Convenciones, Ciudad de la Habana, Cuba http://www.cujae.edu.cu/eventos/cier Participe en Universidad 2008. 11 al 15 de febrero del 2008.
