Is anyone Hearing or Making any Voice Contacts with ISS?

I have been trying for many ISS passes, over the last few days to make voice contacts on 2 meter 144.490 tx and 145.800 Rx using a 3 element yagi and a kenwood TM-261 with no luck of hearing a transmission or making a contact. I am new to this. Is anyone having any luck? Maybe I am doing something wrong? Are they not just communicating right now? I am using this site for Keps and also HRD, and there seems to be a difference in the time frame of the two models, one being ahead of the other. Any advice as to make these contacts with ISS would be greatly appreciated, i.e. specs etc. or other models/sites

Thanks for any advice or help

STS-135 Days 7 and 9 ...

Looks like Days 7 and 9 of this mission have "free time" scheduled for the U.S. astronauts ...

Radios switched off sometimes

Hi Andrew,

One reason you may not have heard any activity from the ISS in recent days is that they have to switch off the amateur radio equipment, whenever another spacecraft is docking or undocking from the Space Station.

There was an undocking yesterday of a freighter for return to Earth.

They sometimes do this well in advance and although on their crew schedule it showed last night (Monday 20th June) that they were scheduled to switch on their amateur radio equipment again, I didn't detect any activity since - so it may still all be off, until rescheduled.

It is switched off for safety reasons.Also new crews take some time to adjust and sometimes don't get on amateur radio for a while.

Hope this helps

received ROISS-3 Atlantis & Nicole head.....

After feeding many squitos, I did get a signal via APRS on a Kenwood D7(G) HT on the 19th over Minnesota. Wrong text? Busy up there unloading supplies I guess.73 All..

Thanks fer the reply

Hey Thanks Phillip, makes me feel a lot better. I have switched my interest in Amateur Radio to All Emergency Power and Equipment, and I am trying to build my own gear from scrape stuff and I am even starting to design some low power Gear to build. I have built my own antennas and I am having great success with everything. Maybe you can give me a better idea too of the satellites that are currently workable on voice especially. I have looked at the different sites that seem to give the lastest stats but hearing it from someone active would be great. Also what is the site where you read that they was suppose to turn the radios back on? I would like to keep up with their daily activity to get a better feel of how they normally operate, maybe for better contact success rates. Any help wouldbe appreciated. I am still working out the kinks on how to decode the stats from the tracking models so I know how to direct my signal, any help with that would be appreciated. Thanks a lot though for the response.

ISS crew schedule amd other things

Hi Andrew,

I am pleased to help.

The ISS crew schedules can be found here:

http://www.nasa.gov/mission_pages/station/timelines/index.html

To find out which satellites are working/status I use this link:

http://www.amsat.org/amsat-new/satellites/status.php

but also it is good to subscribe to:

http://groups.yahoo.com/group/Work-Sat/

On this Yahoo group there is excellent new starter advice about which satellites are easiest to work, the FM voice ones being generally considered to be the easiest. I would have recommended AO-51, but recently it has been in decline so please visit the group for the latest advice.

Some satellites status can change very quickly and this isn't always reflected as fast on websites.

For satellite tracking I would use either

SATPC32 v.12.8a or more recent

or Orbitron 3.71 or more recent

Please also look at my website http://www.qsl.net/g0isw where you will find links to most other things too.

Hope this helps

All the best Philip G0ISW
