ISS voice transmissions

Hi,

I too had to fiddle with the squelch a bit to start with, (had to close it

down a bit more than I thought I would have needed to). I also pick up

intermittent noise on the ISS frequency even when there are no passes

(thats with the base station). With the hand held theres even more. Like

you said Darren, probably picking something up a bit more local.

Yes 12dstring, i too heard the American accent, he was obviously

discussing the effects of space on his body and how he was now able to

do "flips".

Dave

PS. I thought it was an American accent

but was certainly speaking

in English

Daft question, but would this one do the job of picking up the ISS transmissions??

It covers the frequencies needed, but being an analogue needle display it would be very difficult to get the right frequency. These tend to be crude TRF (Tuned Radio Frequency) receivers, you really need a synthesized, digital display type receiver to get the frequencies cock on.

Managed to record a couple of minutes of today's 19:36 (local) pass.
This time on 145.800.
Not that strong and soon faded away.
Sadly my "sky pointing" weather sat antenna seems to developed a fault... More like the cable has come away

so I'm relying on my vertical ham antenna which isn't designed to point skyward. This limits the amount of receive time I have. The other antenna looks horoizon to horizon as it's designed to track polar orbiting WX sats.

The good news it that I seem to have the auto record working. Only problem is I get a new file for every "Over"
My next plan is to swap receiving radios and put my MVT-7100 inline instead of my FT-817. If a radio is going to be left on 24/7 I'd rather it NOT be my FT-817. I know that the 7100 can handle the pace. My 817 is too precious

There is another (visable) pass at 21:09, hopefully some of the raduio chatter will be in english

Just watched the 21:09 (local) ISS pass. Wonderful!!!!
Sadly nowt heard on the radio.
I was amazed at just how accurate the Heavens above prediction was.
There are some clever people in this world!

Darren

PS Now waiting for 22:45

Yea, saw it too, also nothing on the radio.

buuuut, I was attempting to point my telescope at it through the whole pass, and out of some 3000 frames, there's quite a few featuring a little little space station....

Hi,

I also saw the 21.10 pass, lovely sight, almost overhead here. Was at

work but still managed a sneaky attempt with handheld scanner but

I also heard nothing

Now at home so will be able to have another go with base station for the

22.45 BST pass which will be at a lower altitude.

Lovely clear night, just put the dob out to cool, looks like being a late

night

Dave

PS. I agree Darren, also very impressed with the Iridium flare

predictions.

Hi,

I think the voice I heard on the Monday evening pass was most likely

to have been that of Charles Simony.

I've just heard about 5 seconds of Russian on the 143.625 frequency! as it passed over Burton OnTrent at 9.30

God, they've got a great job!

Hi,

Anyone else heard anything from tonights passes ?

Unable to get access to scanner tonight

(whilst at work) but saw

the 21:30 BST pass. Will have a go at the 23:05 BST pass. Might be

worthwhile scanning the two frequencies (143.625 fm and

145.800 fm) .

I was outside trying to get pictures of it, and didn't have the time to get the scanner.

I'll have a go at 23:05, scanning between the two freqs.

Hi,

Any luck with your pictures Dave

Dave.

Yep, I used my refractor this time, as my reflector turned out to be rather uncollimated. So I got sharper images than yesterday:

Hi Dave,

Very well done. Certainly a lot sharper than the reflector. I imagine

pre-planning is the most important thing here.
