station setup
by Eric Fort 29 Apr '07

29 Apr '07

I just recently bought an ft-847 that I'd like to use for sat work. My interests are primarily voice modes NOT PACKET! I may be interested in using CW at some point but as for now my CW needs serious help. I'm located in DM14db and have limited space for antennas at this location or enough space for a full AZ-EL setup if I can remote the station to a location about 30 miles north. What else do I need in terms of antennas, (rotators), preamp, etc. and what birds will it allow me to work for both possible situations? What are the advantages and disadvantages of computer control for doppler shift and tracking? is computer control of these parameters good enough that 2 stations could ragchew on ssb without manual intervention? In each of the 2 different situations above which sats will I likely be able to work and what kind of operating will I likely find there (ragchew vs callsign/RST.) Thanks for the replies and look forward to working some of you on the birds, Eric KG6KQT

western ao51 passes
by Robert Coppock 29 Apr '07

,,,, ,, i have a suggestion. can we try to limit the amount of banter, WX reports, etc. on ao51, especially on the weekends, when many people are wanting to get into the bird? i am not trying to create conflict, but there seems to be the same few people who make a contact with a new or rare station, then immediately go into "ao40/ao07" mode. maybe there would be more support (fund$) coming into amsat if more people could use the bird. hey, i have not paid much dues into this hobby for sure, just trying to open it up a little bit. the single channel FM birds have finite space and time, so please, lets "share and care". thank you for your consideration. 3 years into this stuff, and it is still a blast! peace, 73 Robert kf0g cm97 and OT, critical mass san francisco was a blast too! no riots, hassles, etc. just 4 hours of bicycle riding around the city with great people and WX.

TS 2000 Satellite Memory Software
by fish7days 29 Apr '07

29 Apr '07

Hi, I use the Kenwood MCP 2000 software for regular memory allocations and various settings. What I can not get it to do (maybe because it just does not do it) is to read and write the satellite memory allocations. Is there a way it can do it, or alternatively, is there another program available to do it? Thx Andre N1AJV

A Tale for 2 years old childrens
by Luc Leblanc 29 Apr '07

29 Apr '07

It is OT and if you dislike OT post don't read this. As we just lost another transponder satellite FO-29 we will have soon to change the nature of this BB as there will be any voice satellite available! I know digital cubes will be all around but it is not my prefer soup. In the mean time here is a little tale for a 2 years old child.. The mouse trap A mouse observed through the slit of a wall the farmer and his wife to open a parcel: Which would be thus food that this parcel hid? wondered the mouse and which was not its shock only to discover that it was a mouse trap. He rush to the barn to proclaim this severe warning: There is a mouse trap in the house there is a mouse trap in the house! The chicken speak first and scraped his back and raising his neck he answered: "Mr Mouse, I understands that it is a problem for you but that does not have any consequence for me that does not disturb me" the Mouse turned to the pig and tells him: There is a mouse trap in the house there is a mouse trap in the house The pig showed sympathetic he answered: " I am very sorry Mr mouse, but I can do nothing to help you, but you can count on my prayers "the Mouse turned then to the cow and he shout his cry of alarm to him: There is a mouse trap in the house there is a mouse trap in the house! And the cow to answer "Eh well! Mr mouse, I am in pained for you, but that does not make me a fold on the belly!" So Mr Mouse turned over from there to the house, the head low and discouraged from having to face the mouse trap of the farmer. In the night which followed, a strange noise was heard in the house, a noise which resembled that of a mouse trap which had seized its prey. The woman of the farmer precipitated to see what had been caught but in blackness, she did not see that the tail of a venenous snake had been grabbed by the trap. Thrown into a panic, the snake bit the woman of the farmer who immediately go at the hospital, but alas, she returned to the house with a strong fever. Everyone knows well that it is necessary to look after a strong fever with a chicken soup and the farmer thus take his machete to bring the principal ingredient for the soup. But the disease of the woman of the farmer worsened to a point where all the friends and the neighbours took care of her 24 hours a day at her bedside and to feed her, the farmer had to make butchery with the pig. But the woman of the farmer did not take best and it ends up dying. Many peoples came to her funeral and the farmer had to kill the cow to have enough meat for all. Mr Mouse was watching all of this and from the slit of the wall he feel a great sadness. Thus, the next time that you will intend to say that one of your knowledge is struggling with a problem which does not concern you, remember that when one of ours is threatened, we all are in danger. We all are implied in this voyage that the life is called. Let us have the eye open on our close relations and make an effort to encourage itself mutually. Remember that each one of us constitutes an important wire in the fabric of another person but our lives are woven in the fabric of the others. One of the best values to be retained in the life is a friend and a friend can at time give some advices not always pleasant to hear... Written in the scope of Georges Tenet book. He quotes in his book an extract of this document which explains the potential risks of an American offensive in Irak to the president many months before the invasion of Irak. Thus, it is known as that this one could generate a wave of world terrorism aiming at the American interests, supplied with an increasing Islamic antipathy with regard to the United States, to cause an instability threatening the modes of Arab States key and to create important disturbances of the oil supply as well as serious tensions in Atlantic Alliance (NATO). I know i feel a bit concerned by our south friend moves but i'm afraid by any collateral damages to a point where i hope to be able to enjoy satellite operation more than watching over my shoulder. I could be listening too much stuff coming from the middle east and probably getting my south friend paranoia but i still think news media keep the boiling hot water pan cover close on this and on purpose... Again a bit OT! but just to let you know it is not all the BB readers who feel concern by satellite and technical stuff. Some are casual watchers with other interest... (eg: my last post with a Croatian reference) I was not reluctant to disclose some personal e-mails i received but i received this one on quite regular basis. Always on a different subject if i can say there was a subject??? Again i'm not commenting on the text... but just to let you know a bit of what i got time to time! Dear Luc Leblanc Ve2dwe ! Subject: Amateur Radio Emergency Service My school teacher of the 1960th Jütta Böttcher at the Schule Iserbarg in Hamburg Germany is one of the many women who want to meet Christ through the Big Brother wave predicted in the book with the title "1984". My property insurer should not facilitate the idea,that radio amateurs' property is available in one way or another. Women in need of Christ (Big Brother) have the Internet, and Messenger services as Praize to meet their Christ. Their Internet Christ naturaly will have to go to the Father, but I am certain they don't need radio amateurs' property for that typical sacrament.

Bob, Before you go pulling the motors apart, try the pots in the control box. There are 4 in there, 2 for the meters and 2 for computer feedback. I have had to replace the meter pots years ago. It's a fairly simple task. 73, John KE3SU --- w7lrd(a)comcast.net wrote: >Hello >I am getting erratic direction readings from my 5400 >az rotor. I am sure it is the pot for the >direction.
