Re: HTs and antennas..

K6LCS <clintbrad4d@...>
 

... Doesn't seem like any of them are full duplex ...
Only that new Alinco HT is "true" full duplex. I have been told by one owner that the most current firmware update does improve what has been described as "poor" sub-band receive sensitivity. I will get one, and see how it works.

And, of course, it is NOT mandatory that we work full-duplex - just a convenience to be able to hear the downlink when you key your mic.

... anyone tried a dual-band quad? Seems like a 2 element 2m and a three element
70cm quad on the same boom ought to be easy...
Ross - with A)-51 at 2.05W downlink power right now, just get yourself a few db of gain both ways, and you'll be successful!

Please keep us updated with what you use for an antenna.

Clint, K6LCS


HTs and antennas..

Ross Primrose N4RP <n4rp@...>
 

Any thoughts on current HTs suitable for working the FM birds? Doesn't seem like any of them are full duplex...

On antennas, seems for the FM birds, crossed Yagis are popular, anyone tried a dual-band quad? Seems like a 2 element 2m and a three element 70cm quad on the same boom ought to be easy...

I just created a quickie, anonymous survey for the Work-Sat site ...
Geeze, twenty-eight of you have taken the time to complete the "customer satisfaction" survey - and your input has been extremely helpful. MANY THANKS for helping me make the Work-Sat site better for all!

Made my first contact!

MichaelE <k4moa@...>
 

Hey everyone,

I wanted to let everyone know that I made my first contact with a satellite today.

I worked K4T on SO-50 this morning. I am sure most have heard that K4T is currently in the Dry Tortugas worked them with my VX-7 and a Arrow Antenna.

I received my Arrow antenna for Christmas and today was the first time I have had the opportunity to get the antenna out (of the package) due to the cold weather, sicknesses and just being busy. This morning I got up and saw how pretty it was outside I had to get out for a bit.

I have tried to listen to SO-50 with my AL-800 antenna in the past and I could barely hear anything, I never felt comfortable attempting to make a contact on it. Today I could hear them almost from the horizon and picked them up perfect as they went over.

I wanted to get on here and thank Clint and everyone who had offered me so much advice over the past several months.

I look forward to making more contacts with you guys in the future...

Take care,

Michael, K4MOA


See ISS as it Grows

K6LCS <clintbrad4d@...>
 

Thanks, Dennis Minnick, for this link.

Watch the pieces come together as they are sent up from Earth. This is the International Space Station (ISS) Assembly diagram, piece by piece. I had no idea the Space Station had grown to this size. Watch the left hand corner for dates.

Re: ARISSat-1

K6LCS <clintbrad4d@...>
 

ARISS is working on the equipment for the new project. I'll post pertinent milestones here ... and, YES, I'll prepare a document on how to monitor it once it's tossed into space!

i saw in april qst page76 a future sat made from suitsat to be set out this year was wondering if its going to be a easy fm sat to work it didnt say to much in the article, its a low orbit sat cubesat design.ke3lb


Re: k4t dxpedition

made contact today 1842 gmt ao27 pass with k4t dxpedition ...
Outstanding!

...didn't do the grids on the computer im so use to logging by pen and paper ...
Copy!

made contact today 1842 gmt ao27 pass with k4t dxpedition with the elk on my rotor set at 45 degrees on my pool deck temporalily till i get it on my garage roof now i dont have to be running out all the time with the tripod and arrow ok 73 ke3lb fn21 .oh by the way clint didnt do the grids on the computer im so use to logging by pen and paper since lincenced in 93 hard to change guess ill do it by pen and paper.


Daylight Savings Time THIS Sunday

K6LCS <clintbrad4d@...>
 

Remember that Daylight Savings Time begins this Sunday! Adjust your satellite tracking programs accordingly.

NASA tells us: "Benjamin Franklin is credited with the concept of Daylight Saving Time. The basic idea is to make the best use of daylight hours by shifting the clock forward in the spring and backward in the fall. Daylight Saving Time has been in use throughout much of the United States, Canada and Europe since World War I... In 2005, President Bush signed into law a new energy policy bill that would extend Daylight Saving Time by four weeks beginning in 2007."

Just a reminder to check the AO-51 Op Schedule - sometimes that frequency changes to another V/U pair!

Dennis - the programming for the FT-60R is in my tutorial on the support site! Just remember that you do not have to compensate for Doppler on the 2M side of things, because the effect is so less prevalent at that frequency.

And my mnemonic device to remember is: "Acquire - Above." You acquire the sat slightly above the downlink frequency. So, if the bird is transmitting 435.300, start listening at 435.310 and 435.305 - and you'll capture it sooner.

Nice going on the first contact and using a FT60 too, I plan on using my Yaesu FT-60 also I am still trying to figure out how to do it, and how to compensate for doppler etc,, I just found out that the little FT60 can work satellites, amazing.

Hello group, My name is Brian Barney. I am a student at Cal Poly Pomona, and Clint gave a satellite presentation for our amateur club last week. I downloaded pocketsat on my palm treo and today I noticed I had an 80 degree overhead pass with the SO-50 (the same satellite that Clint contacted during the presentation)
I waited till it was almost directly overhead and I could hear people clearly. I waited for a break in the conversation and threw out my call sign and location. The other hams said my signal was pretty scratchy but could understand some of it. I was just using a whip antenna. I was already in the process of making a dual band yagi, but I thought I'd try with my $20 whip and FT60.
Thank you Clint for giving the presentation for our school club, I had always wanted to work satellites, but didn't know I had the capability to.
