ISS

tolsher21 <ddvorack@...>
 

I am new to satellite work, and today I tried to make
contact with the ISS. I had the correct elevation, and time, but
did not hear anything on FM voice. The elevation was good, so I should have heard something. I can hear the packet bursts, but no voice.
I am receiving on 144.490 and transmitting on 144.490.....is my
receive frequency wrong?

Appreciate any help!

Thanks,
John KD8BIN


Re: working sats with vx7r

That's what I use. It works ok. Just turn the squelch off and program the tx and rx freqs and connect to an antenna.  It can't hear while you transmit but a lot of others don't either.  Just got to work harder and hang in there. I have a lot of contacts and don't do it everyday.

... Can you use the Sat for emergencies, ( I'm at sea and my boat is sinking, Help!! )?
This message group - and my Web site - promote the amateur FM sats - and none of them are used for emergencies.

The odds that your 911 situation occurs at the same time a ten-minute sat pass occurs is, well, rather slim. And we do NOT have a geosynchronous ham sat available.

HF and sat phones are commonly used by your sailing/boating crowd!

What's the future for Sat Coms

charles
 

I'm new to all of this,and that's why I ask? I see yawl are using HT and manually pointing antennas to the Sat, after locating them by soft ware,and working Dx.If I have the above right? Can you use the Sat for emergencies, ( I'm at sea and my boat is sinking, Help!! )?, can you Receive info from other SAT using FM or SSB, like WX? what would a table top rig like The ten-tec 526 work?

Re: working sats with vx7r

K6LCS <clintbrad4d@...>
 

A VX-7R is a great rig for working the FM sats!

Although not a true full-duplex radio - it is a great HT.

I prefer split freq mode - page 46-ish of the manual - where in one memory location you can program 440 downlink and 2M uplink - like in all the sat frequency charts at ...

I have never stopped regretting selling my FT-817 a few years ago.  This is yet another reason.  I can handle cross-band as long as it's FM, but cross mode like this is a deal breaker...sigh!

> The single channel transponder will operate in a similar way to the amateur satellite AO-16. The uplink on 145.900 MHz will be FM and the downlink on 435.020 MHz will use the BPSK telemetry beacon transmitter to produce Double Sideband (DSB) that can be received on an SSB radio.

PW-Sat in January, 2012

K6LCS <clintbrad4d@...>
 

PW-Sat, a 1U CubeSat to be launched on the first VEGA flight in January, will carry a 145 to 435 MHz Amateur Radio transponder.

The single channel transponder will operate in a similar way to the amateur satellite AO-16. The uplink on 145.900 MHz will be FM and the downlink on 435.020 MHz will use the BPSK telemetry beacon transmitter to produce Double Sideband (DSB) that can be received on an SSB radio.

PW-Sat should be launched into a 1450 by 300km 69.5 degree orbit and may be expected to have a lifetime of about 2 years before re-entry. It was built by students of Warsaw University of Technology in cooperation with the Space Research Centre and will be Poland's first satellite.

PW-Sat has five modes of operation:

1. Receive only mode – no downlink
2. Beacon CW mode – Downlink On-Off Keying (OOK) CW (1kHz) 12 WPM on 435.020 MHz
3. Beacon BPSK mode – Downlink BPSK (3 kHz) 1200 bps AX25 (1 frame on 20 sec) on 435.020 MHz
4. Control communication mode. Downlink BPSK (3 kHz) 1200 bps AX25 on 435.020 MHz
5. Voice Repeater mode (aka "AO-16&#8243; mode) – Uplink145.900MHz FM (15 kHz) Downlink 435.020MHz DSB (3 kHz)

Work AO-51, ARISSat-1 NOW!

K6LCS <clintbrad4d@...>
 

AO-51 shouldn't be working. I mean, two of its six battery cells are shorted. It should be dead. INSTEAD, it has been pumping out more than 800mW the past two months - a true testament to the engineers who built it, and our ground crew controlling it.

ARISSat-1 has about run its course. Its orbit is deteriorating. It only works well when in direct sunlight. If you haven't bothered to simply program 145.950 in an HT with a better antenna to hear any of the kids' pre-recorded "Welcome!" messages ... well, you're missing out.

Work these two birds now! We will not have them around much longer!

ARISSat-1 Poll

K6LCS <clintbrad4d@...>
 

My informal "poll" of Web site visitors to ...

http://web.me.com/clintbradford/Work-Sat/ARISSat-1.html

... were given a link to an informal ARISSat-1 poll: "Will You be Working ARISSat-1?"

Almost 300 responded, able to choose multiple modes ...

YES - Monitoring the FM voice announcements, 249 - 34.16%
YES - SSTV, 132, - 18.11%
YES - Transponder, linear, inverting - SSB/CW, 114 - 15.64%
YES - Telemetry, 99 - 13.58%
YES - Morse code beacon, BPSK-400, 66 - 9.05%
YES - Morse code beacon, BPSK-1000, 66 - 9.05%

No interest - sorry! - ONE, 0.41%

JOTA voice contact on the ISS

Doug Cook
 

Jamboree on the Air station WB5BSA contacted astronaut Mike Fossum on the International Space Station, Saturday evening during the event.

I tried to create an antenna that's a symbol of both Scouting and Amateur Radio.

I lashed together as a pioneering project a beam antenna made of pieces of wood and barbed wire - a barbed-wire beam. The lashings secured the elements and with it and a Yaesu VX-8R HT operating at 5 watts was able to make a voice QSO with Mike from over 1200 miles away while he was over the Yucatan Peninsula.

Ham Nation will be interviewing me tonight on the QSO as well as an Eagle Scout that has his general license and was working the event.

Tuesday evening 7:30 to 8:30 pm CDT on twit.tv. This program was moved ahead 30 minutes due to studio requirements from it's regular 7:00 pm slot.

Hi Clint,

Yes, I heard you on the satellite from PACIFICON. I was hoping for the chance to say hello when another station jumped in. Then someone asked, "What's PACIFICON?" Then another station jumped in. At that point I was losing the satellite - Oh, well, I look forward to another time to say hello.

About 47 for the second show. Then we worked passes outside: A0-27 "showed up" mid-pass for us at about 245PM PDT. Then AO-51 again for a GREAT pass at about 3:53PM PDT.

The event didn't formally get a request in to work Commander Fossom aboard the ISS for his 3:06AM PDT pass on early Saturday morning ... He worked a Scout group FIVE MINUTES before streaking across Santa Clara - but his radios were already turned OFF for a while. BUT our group of several kids/Scouts/parents/hotel security staff enjoyed a video I had set up on Fossum's NASA career, and we all had a great time - albeit 3 o'clock in the morning ... (grin)

The PACIFICON organization is a first-class group. They treat their speakers well ... offer all aspects of the hobby to their attendees ... and gave it all to us in a comfortable venue (Santa Clara Marriott). They will be hosting the NATIONAL ARRL Convention next year!

More will be posted here later this week.
