ISS Field Day configuration?
Hi all!
There might be a good possibility that the ISS will be active during Field Day this year, like they have in previous years. Just wondering what frequency split will they be using?

The best thing to do will be to listen to the first pass that has yo in the footprint, and to try to check out the VHF voice downlink (145.800) and the packet downlink (145.825).
If you're hearing other Field Day stations on the voice downlink, the repeater is in use and the uplink is 437.800 +/- Doppler. If it's packet, it'll be simplex.
If you hear astronauts and do not hear the other side of the contact, they'll be using split-VHF operation. For us here in North Amrerica, the uplink is 144.490, with the standard 145.800 downlink.
A note to anyone who hasn't used the ISS Mode B (U/V) repeater when it's been operational - Doppler tuning is most critical on the uplink. I leave the downlink parked at 145.800, but I definitely tune the uplink, starting on the low side and tuning up. Start at 437.790 and tune up from there. You'll spend the most time at 437.795, then 437.805.
Doppler tuning the ISS uplink will make a lot of difference in your ability to get into the repeater.
I hope the ISS is active for FD in some configuration.
Best of Field Day luck and 73 to all,

On the most recent pass (08:10 edt) was the bird in TLM mode? I heard nothing throughout the pass until the bird was way down over Mexico (and the angle would have been low for the command stations) when there was a definite change in the received audio - I am assuming that the command station then returned the bird to analogue mode before it was out of their footprint.
Can someone confirm?
Many thanks

Right now the ISS is in 2m split mode? 145.825 up 145.800 down RS0ISS-3 packet.

Over grid FN26 there will be 6 available pass starting 0122 EDT on June 28 most of them will be on the night shift but some real good one early morning the 28 until the last one 0919 EDT June 28
Just to remind that only ONE (1) satellite contact is required to have the ARRL100 satellite bonus points. Never heard if AMSAT-NA will also have his satellite field day but it's not helping the ARRL Field Day as multiple QSO'S are allowed.on a very restricted satellite aging fleet.
Not to mention there is about no rules who stands and it is not a friendly QRP area... The moto is the bigger and longer CQQQQQQQ EEEEER. It will be interesting to have some negative points for poor operating practice? It's easy to spot and post but not too flattering for the offending station.
Just to remind some offended virgin ARRL has his check log for numerous years and no one complains. (Those on the check log could be...)
Happy field day it will be a whole week end of rain and heavy thunderstorm here!

Yes Luc ... the first satellite contact made will earn that ARRL entry the 100-point bonus for a satellite contact.
It's also important to note that ARRL and AMSAT are only scoring one contact each on AO-27 and SO-50. AMSAT Field Day rules permit one contact each on each of the active transponders on AO-51. If the ISS is configured to be active both in FM voice and packet, AMSAT also will score one voice contact and one completed two-way packet contact.
ARRL Field Day rules stipulate only one contact per FM satellite will score.
I have sent you the 2009 AMSAT Field Day rules off the BB. I hope that proves helpful.
Best of luck to all this Field Day - and please listen for W4G on all of the satellites!

Jeff,
As always, a good but not definitive source is the ISS Fan Club site:
In the upper left of the home page are reports on the various modes, including where relevant the uplink and downlink. Checking between now and FD start will give you a good idea, though last minute changes can and have happened.

Hi Alan,
I already have that website bookmarked! :) My concern is if something changed it wouldn't be updated fast enough, not the blogger entries, the status of the repeater, etc. Seems to me that last year and before, the time leading up to FD there were more bulletins from reliable sources giving a heads up about the possible activity from the ISS. This year it seems mute.

Apologies if this has been sent around already - I'm only catching the tail ends of the conversations these days.
Good EME article in this weekend's Times:
