There is a great deal of information on the ARISS web site www.ariss.org
<http://www.ariss.org> .  News of note is usually posted on the main page.
This includes the fact that our first (of two) next generation radio systems
is getting ready for launch on SpaceX-20 (tentative launch date--March 2).
Look under the news tab for upcoming school contacts (with a 145.80
downlink).  Weekly reports provide a view of what is happening in the ARISS
community.  General Contacts Tab provides info on working the ISS (Primarily
APRS and SSTV downlinks).  Joanne's APRS resource guide is linked on this
page.  The link to the SSTV galley can also be linked from this site.



Enjoy!

1. Is this the best way or place to post such questions?

2. I have studied past posts and other sources but can't find answers to

questions below.

3. I am trying to listen to ISS. N2Y0 and HeavensAbove list the same pass

for my location today (FM14be, 16:39 local time, elevation 56 degrees) but

AMSAT predictor says 4 degrees for that pass. Why the difference?

4. N2Y0 says up/down is 437.550/437.550, ASFK, inactive. HeavensAbove says

145.825/447.550 FM

active. Who is right? How can I get correct frequencies to listen to?

thanks

Isaac

Hi,

There may be some short outages in the operation of the warehouse today as I
make some changes to the reporting.

The dashboards will resume uploads each time the warehouse comes back online.

Realtime min-max values may look a bit strange until I've stabilised the
service later today.

Thank you all for supporting the project

Mark, thanks for your description.  I followed it but could not see my 2M
"birdy" move at all when enabling/disabling the reference board output!  I
would like to assume that my 9700 is just so stable that the reference
board is making little difference.

I did hear a very slight beat frequency change when I enabled/disabled the
reference board output.  What I did was adjust the coarse and fine sliders
in the Ref section of the radio until the beat frequency was zero WITH the
GPSDO output on.  I could hear a slight beat frequency when I shut it off.

Think that's a valid test?  I have yet to repeat all this at 23cm.

I was expecting a whopper correction using the GPSDO.

73,

Bob W7OTJ

Great. Sounds ok, Bob.  Other testing I did-look for harmonics of the
injected freq!! That was fun and confirming.  Did on all three bands, since
there were good multiples to listen to on each band.  Zoom in waterfall and
then turn signal off and on :-)  Get out the calculator....2M is 3x right??
49.152x3=147.456.  Keep going....showed me it was spot on all three bands.

Thanks for the confirmation.  I am just tickled with the 9700.  Next up is

 I am looking for a 2 meter receiving converter that uses an HF IF
frequency.  Want to use it with my Kenwood TS590SG to receive the satellite
downlink frequencies for Mode B satellites.

If you have one available, or even a 2 meter transverter at a good price,
let me know the price shipped to ZIP 73507.

Hi Eric, mobile so brief. Better stability over time and temps.  It?s not
essential, just desirable for some. The 10 MHz injection on a stock radio
doesn?t do what you might expect, based on other Icom radios.  Best advice
is for interested people to read the traffic in the groups.io 9700 group!
There is another option soon as well, but there are tradeoffs.

Is HuskySat really only transmitting with 13 mW?   If yes, is that
healthy?  If no, what does that value represent?

Hi Roy,

It's a great question. Any analysis you can do is helpful. We think the
sensor reading is wrong as we can't see a difference in the received signal
strength on the ground, but any independent validation of that is
greatfully received.

Subjective observation is that my received signal seemed weaker for the
past 2 or so days. The antenna I'm using is a 7 element yagi on 435.800
at 20 degrees fixed elevation on a TV rotor. I've only been able to
capture fewer than 50% of the packets compared with reception earlier in
the week.

I live on a 100% wooded lot (no leaves since its winter) but all the
trees are frosted ala winter wonderland style from passing weather
systems since last Thursday. The trees introduce a lot of variability in
my received signal depending on which tree I'm pointed at. But my
received signal on 435.800 has been noticeably lower even at the "good"
patches of sky.

My HuskySat telemetry at 2125Z said Forward Power = 13.4 mW.

Subjective observation is that my received signal seemed weaker for the past
2 or so days. The antenna I'm using is a 7 element yagi on 435.800 at 20
degrees fixed elevation on a TV rotor. I've only been able to capture fewer
than 50% of the packets compared with reception earlier in the week.

I live on a 100% wooded lot (no leaves since its winter) but all the trees
are frosted ala winter wonderland style from passing weather systems since
last Thursday. The trees introduce a lot of variability in my received
signal depending on which tree I'm pointed at. But my received signal on
435.800 has been noticeably lower even at the "good"
patches of sky.

My HuskySat telemetry at 2125Z said Forward Power = 13.4 mW.
