[amsat-bb] College Satellite this Thursday evening
It's time for another College Satellite night! We hope to see you on the birds Thursday evening May 6th from 22:00 UTC to 0500 UTC (May 7). College Satellite nights are a monthly event held the first Thursday of the month. Mark your calendar and spread the word to college hams/club stations that you know! College club stations plan on being on birds AO51, SO50, AO7, VO52, HO-68 and more. Please give these stations a call and work them.they will identify their college club identity along with their call sign. 73, Dr. Jay Garlitz, AA4FL Gator ARC Faculty Advisor at UF, W4DFU trustee www.gatorradio.org http://www.gatorradio.org/ ___ Sent via amsat...@amsat.org.

[amsat-bb] GP47 Activation
My operation from Søndre Strøm (aka Sondrestrom, aka Kangerlussuaq) GP47pa will start sometime around Wednesday, May 5th. I will be traveling to Søndre Strøm tomorrow and will hopefully not fly the next day. I plan on being there a little less than two weeks. After that I will be returning to Thule FQ56. Be sure to sign up for my email list at http://groups.google.com/group/ox-thule-2010 if you have not already done so. I will send out notices from here with planned times of operation. Also, a big thank you to everyone that I've worked. I'm just as excited to give out these grids as you are to receive them! Remember: I will need to have cards printed up when I get home so there may be some delay in my reply. I will QSL all cards sent with SASE, IRC or Greenstamp 100% don't worry! Thanks again everyone! Get the word out to everyone you know and invite those not on the birds, or in ham radio, into your station to make a few QSOs and show them how easy it is! 73, Reid N0RC ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: AO-51 update
I vote for V/S: there are a lot more station capable of mode S than L... (and hopefully, HO-68 will be in linear mode - I suggested that to Alan Kung several months ago) George, KA3HSW Additionally, the AO51-modes group would like your input on the desired Field Day mode. We will likely be limited to one transmitter operation. With AO-27, SO-50, and possibly SO-67 and HO-68 on V/U FM, S band or L/U operation is looking very promising to provide some variety. 73, Drew KO4MA AMSAT-NA VP Operations ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: AO-51 update
Tim, Your point is valid. There is another way to look at this, though. In general I find that on Field Day the mode FM birds are NOT a good way to show 2-way satellite communications to a group or club. I have tried to make a contact (portable, handheld operations) for the last few years, and it's been a bust. I have generally gone to just receiving the birds, rather than creating an expectation for a contact that I can't deliver. And AO-51 isn't the only operational bird...so putting the bird into mode L/S or L/U might actually allow more stations to make contacts on Field Day. Food for thought :) Mark N8MH On Mon, May 3, 2010 at 1:47 PM, Tim Cunningham tim_cunning...@charter.net wrote: If the desire is to promote Amateur Radio Satellites on Field Day for the greater majority there will be more stations with V/U and/or V/S capability than L/S or L/U capability based on historical observation.

[amsat-bb] Re: AO-51 update
...to promote Amateur Radio Satellites on Field Day for the greater majority there will be more stations with V/U and/or V/S capability than L/S or L/U capability based on historical observation. Which is why it is not a good idea to use V/U because it demonstrates a totally saturated and unuseable satellite channel. Uplink congestion on VHF where the link budget is 20 dB stronger than the downlink is the limiting factor and it is total bedlam/gridlock on FD and is a poor demonstration to the rest of the community and to other observers. The L/U would be the best demo, because the uplink contention will be much less, yet EVERY field-day site can demo the downlink. The FD demo should not set themselves up such that a successful 2-way is required for success. Such stations will fail. It won't happen, or if it does, it happens by stomping all over others. This is not a good dsmonstration for ham radio at FD. Better to plan on success as demonstrated by good downlink reception. THen everyone is successful. And the downlink is nice and clean just as we all dream of. Bob, WB4APR You can promote variety or you can promote AMSAT to the greater Amateur Radio community.

The sticking point remains there are many prospects who will not get the chance to listen to these bands. That is is unfortunate! Experience solidifies that Field Day is a poor time to demonstrate an FM satellite, so I am going to save a day other than Field Day to positively demo an FM bird. Any FM satellite will sound the same with the same number of participants. If you limit the playing field you simply reduce the number of players. I think this is how we get the an elitist label, but I will bite the bullet and demo L/U on Field Day if that is what is playing (a bigger radio and more gear unless I can get a converter to work with my D7A HT. Do you want to put a MIC-E position burst on the end of your transmisison? It may make an interesting Roger Beep... Can you count that as a 2-in-one contact (voice and digital?) to keep things interesting. Of course using 9600 baud for the MIC-E who would even notice the signal? Maybe a little innovation here?
