Well, one-way, and I didn't have the presence of mind to try to make a cross satellite contact.
The end of the last AO-07 pass (which sounded very much like 20 meters!) crossed with the beginning of FO-29's, so the two satellites passed within a couple of hundred miles of each other. Since the downlink for AO-07 is in the middle of the uplink passband for FO-29, I switched over to FO-29 to take a listen. Sure enough, the bottom of FO-29's passband sounded like 20 meters for a few moments. Then it went away.
Fleeting chaos. Sweet.

The birds were overcrowded... I had an arrow type antenna set up (split the UHF and VHF beams on to 2 separate booms on my G5400 being controlled by LVB tracker and SATPC32 program for demo purposes) with my Icom 910 and it was difficult to even get the 100 point contact. Made a few contacts and Maybe next year we all can set up the one contact per bird rule and KEEP it! Was fun and the questions I had with my set up perked interest from the people that were "onlookers" Sorry to WB2OQQ and others that I know but the interference was a bit much to overcome. Hope all had a great Field Day. 73, Dee, NB2F At "K2BAR"

I got APRS satellite packets via ISS but not while I was looking.
My KEPS were 2.5 days old and I heard nothing during my "predicted" passes, though looking at the APRS radio later, I did see RS0ISS and 3 other stations. Maybe they re-boosted.
I did think I heard voices from that radio once or twice but assumed it was QRM from nearby public 2-way radios (I was surrounded by the Race Across America Bike tour people who all had VHF radios of some kind or other). Now I realize it might have been an astronaut on ISS? But since it didn't match my prediction, I wasn't paying attention.

Hi Bob,
Yeah, Keps for the ISS have been really short lived recently. I updated mine on Friday, and I think again yesterday, and by last night when I updated them again, things moved out another 20 minutes. I think someone forgot to turn off one of their thrusters...
I tuned in for their 6pm (local PDT) pass, and heard nothing on 145.800 nor 145.825. I stayed up last night to catch the 12:40am pass, and again nothing (though I only stayed around for the first half of the pass). Nothing has been posted on David's OSCAR database related to hearing the crew either.
Their next pass here is after Field Day closes, so I'll have to look forward to next year. But I did make contacts on AO-51, AO-7, and FO-29, and a partial on AO-27 to Hawaii, so it still was a good day.

I am pretty sure the ISS got reboosted somewhere yesterday afternoon EDT or the Keps across the whole web were off. I have been tracking it non-stop with the slim hope of making a voice contact. When I updated my TLEs this morning, the ISS pass predictions were *really* off like a reboost happened.
Also as Bob stated, when I went outside yesterday to listen for voice, I heard nada. But what was weird is APRS-IS was showing packets in Canada when all the usual suspects showed the ISS over France! :-(

Actually, the later (North-heading) pass of AO-51 was remarkably sane. I made my 100 point contact with AA5PK, and then sat back to listen. Towards the end of the pass it was pretty quiet, so I answered W6YX who was actually having to call CQ for some attention.
But AO-7 literally sounds like 20 meters. I've never heard it so busy. The Old Girl is holding up extremely well, and I had much better luck there than with FO-29, which seemed to be suffering from the onslaught. AO-27 was super busy too, so I decided to wait for the mid-Pacific 3-degree pass. Almost snagged the NH7 station... Sorry, just couldn't pull out the call sign as the bird set. Time to buy a better preamp and get it mounted directly on the antenna boom (instead of 10' and a cable splice away).

I actually made most of our (W9CCU) contacts on FO-29 this year, with AO-7 and VO-52 close behind.
REALLY disappointed at the number of stations making multiple contacts on the FM birds... what these people don't seem to realize is that every extra contact they make deprives another station of the opportunity to make their one FD contact.

If someone called CW FD 3 or 4 times without any answer it is a plus if this station give him his first one but if FD stations are only adding contact to their log i agree it is useless on Field Day

I know, Possibly they do not know what is happening? (Doubt it) how to fix it? I also do not know. This is one of the main reason I hate the CB fiasco of the single channel FM birds. Especially because of the nature of the FM capture effect. The Bully with the biggest signal is the only one heard.
This may make it even more CB'ish, but maybe once a station has worked someone, then everyone else starts CQing again? Yes a massive mess.
I feel the ideal would be the one QSO per station during FD. As it is intended to be. Maybe have an OO monitor passes like when FD is happening and send out pink slips to all that do not abide by the one QSO policy during FD?
Or what probably would be even faster than the one QSO per station, would be to run QSO's like a sprint type then each station gets 2 QSO's and are gone.
Typical would be like this.
CQ Field Day this is W9ABC W9ABC this is K9K9XYZ K9XYZ we are 1A Wisconsin QSL we are 5a Illinois QSL Qrz this is K9XYZ K9XYZ this is W9AAA W9AAA we are 1A Wisconsin
etc.
I don't know. A simple small linear transponder would be soo much nicer. And not all that hard to make either.
But alas we keep putting up these FM birds. UG>

Joe,
I feel the ideal would be the one QSO per station during FD. As it is intended to be. Maybe have an OO monitor passes like when FD is happening and send out pink slips to all that do not abide by the one QSO policy during FD?
Other than possibly having the OO's cite the operator for not following "good amateur practice" in FCC part 97.101a of the FCC rules, what could an OO do? There is no FCC rule that says operators make one and only one QSO on an FM satellite, and OO's are not in the business of upholding contest rules. If stations are identifying and not causing willful or malicious interference that could be cited under FCC part 97.101d, and aren't violating any other part of the FCC rules, then the OO has nothing to send out a pink slip for. Even if an OO were to send out a pink slip, the station would receive it a few days after the Field Day weekend - which doesn't help matters during the weekend.
I don't know. A simple small linear transponder would be soo much nicer. And not all that hard to make either.
We have 3 that were used a lot over the weekend, much more than normal. When it isn't Field Day, there are many times where stations can call CQ for an entire pass on those satellites yet work nobody. I even saw this a couple of times on Saturday afternoon, where I moved higher in the passband so I could hear my downlink easier, yet nobody responded to my CQ calls. Or everyone crowds the center of the passband and ignores the remainder of the 50- to 100-kHz transponder, making it almost seem like you're on an FM satellite.
73!
Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/
I have to agree with Patrick on this one. We also checked the frequencies up and down from the center of the passbands and there was little activity. Just spread out. It was wonderful to see that there was so much activity. As for the FM birds - it is what it is. One frequency with capture effect where two people are happy and the rest does not make it. We, deliberately stayed clear of the FM birds and focused on the ones with linear transponders. We were better prepared to work the Satellites than ever before. SatPC32, LVB Tracker, G5500, IC910 with Rig Control. Nature favors the prepared :-)
