HFU HF Underground

Finally I find some success monitoring UHF SATCOM. Still trying to figure out why but for whatever reason, a lot of UHF SATCOM transponders showed up plain as day on my SDR early this AM. From 243.5 - 270 Mhz it was chock full of transponders. I even had some voice traffic.
Can someone please ID the language from these two recordings? Translation would be wonderful too, if possible.

Thanks!

What time of day/night are these recordings?
What part of the sky is the antennae pointed at?

In the last 2 hours. (So around 4AM local.)

It's a Diamond D3000N discone. It's pointed up! :P

How long did it last and is it still going?
Which "UFO" satellite is this?

Those conversations lasted a while. I signed off for the night but don't think they were still going. I picked up a few other weaker signals though.
UFO sats are geosynchronous so I guess it has to be UFO 4 & 8 over Pacific ocean. Per the sat footprint though I'd be at the very edge of reception. This is why I always believed I had poor chances of catching any traffic.
Perhaps the conditions across Pacific are helping UHF signals...

What other frequencies other than the ones listed above were noted?

Don't recall off-hand.

With a disconey for ant, I suspect the closest bird is who you heard.

Hey Nick
That language is Brazilian Portuguese. Those are coming from CONUS transponders.

They are fairly strong signals, I get them with just a discone as well. Years ago I had a large helical antenna on a rotor, but sadly a winter storm destroyed it.

Thanks. Yeah I listened for quite a while last night and the language is starting to sound more familiar. I finally figured out which sats that are within my footprint. Looks like I have UFO 3, 4, 6, 8 and FLTSATCOM 7. I didn't realize they do move slightly and it looks like they start coming really alive around 11PM local.

Hehe, I feel a little stupid. I purchased a BHP-150+ from M/C a while back. About a week ago, I put it back into my discone's receive chain, which normally just monitors local federal activity.
I removed it last night as a test and sure enough, the signals (while still there) are much weaker. Without tweaking the SDR waterfall + gain settings, it'd be easy to miss. I've never had much luck with SATCOM in the past so I never gave it much thought.
Looks like I have a new interest to dabble in! :)
