Hello group-
I am relocating back to SFO from Anchorage,Ak.
We plan on being mobile and ELK/HT portable from July 23-Aug 4..

Route is Anchorage - Fairbanks- Tok,Ak- Whitehorse,Yukon -Prince George, BC
, WA ,and south to SFO.

Will try to post pass attempts here pending cell mobile service etc..
(and on my closed facebook group "hf radio plus")

Have hf/6 mobile too... Will chk in to "Noontime" & AK hf nets etc..

Hope to wk a some of you!

Yes, PSAT is in safe mode (digipeater off). We switched off all the position
packets, bulletins and sunsensor telemetry.
It would be very helpful to collect telemetry worldwide.

Is NO-84 OK? I seemed to hear a lot fewer packets than usual on this

Could be me. Just checking.

The reason I ask is because the other day when ISS was xmit SSTV, I was
able to digipeat through the 145.800 ax.25. As this was my first ever
try at such a mode, I wasn't real sure what the heck I was doing.

The last couple days I have tried to digipeat through but don't even
hear anything on 145.800/145/990 .

Hi,

There is a problem at the hosting company and we may experience a few

The frequency is 145.825.

It's been reported on for the past couple of days. It is generally always
on unless the radio is in use for an ARISS contact, there's an EVA, or an
arrival/departure of a cargo or crew vehicle.

As the Soyuz carrying the Expedition 44 crew is scheduled to arrive this
evening at 0246Z, it will be off for some time before and after that.

Hi Bob,

Two different radios are used on the ISS. The SSTV pictures on 145.800 were
sent using the Kenwood rig in the Russian segment. The packet digipeater on
145.825 is an Ericcson HT at lower power and different antenna than the
Kenwood rig.

On Saturday when the SSTV signal was still just an unmodulated carrier on
145.800 I was able to digi on 145.825 up/down.

This is what I understood too, but why do they use the lower power HT for
ARISS school contacts? Is it because they have that headset for it that
makes it easier to hear questions perhaps?

The Ericsson (M-PA Series) transceivers are on board in the ISS Columbus
module which is closer to the common work and living areas. The Kenwood
radio is located in the ISS FGB Service Module (Zarya).
http://www.ariss.org/contact-the-iss.html explains more.

One radio is in the Colombus module and used by European, Japanese, US etc.

The other radio is in the Russian segment.

At the moment the Russian segment is being used for school contacts as
there is no astronaut in the European section with a licence.

So two radios, two different locations. There was a high power radio
in the Colombus module but it is not working. The handheld is a
backup, currently in use.

The two sections are as such independent, with co-operation. There are
different voltages in different sections which also makes moving
equipment from one to another very difficult. The section used depends
on the Nationality of the astronaut. SSTV always seems to be Russian,
probably due to equipment in that module. Packet is always European,
as far as I know.

I dug up an older ARISS posting which hopefully adds a bit more to the good
explanation by Dan just a minute ago:

---

The "new" radio is actually a Kenwood D710 which is located in the Russian
Service module. The Service Module is where the ARISS team performed most of
its contacts in the past as it was near the table where all the crew had
dinner.  Since the first contacts with ARISS in 2000, the ISS has
significantly expanded, both in size and in crew size.  ARISS has expanded
too, with an additional station location in the Columbus module, which is on
the other end of ISS (about football field in length).  This is where the
US, Europe, Japan and Canada conducts most of its experiments and where they
spend most of their time.  Right now we are using a lower power radio, an
Ericsson handheld, in the Columbus module, as it was already on-board ISS
(launched in 2000).  Our near term plans is to upgrade the Columbus station
to a higher power radio (mobile radio class).  Keep an eye out for these
plans to mature.

Note that we are unable to move radios from the Russian segment (Service
Module) to the US segment (where the Columbus module is located) as the
power systems are different (28V vs 120 V) and certification for the Kenwood
radios was only performed for the Russian segment. At the last ARISS
International meeting, the delegates agreed with a plan to make sure all
future equipment is interoperable and certified across the ISS.  This will
cost more money and take more time, but should provide more equipment
flexibility for ARISS.

For now, APRS is using the lower power radio in the Columbus module.

I hope this helps explain things.

Thank you JoAnne and Bob. I really like learning about the ISS through ham
radio/ARISS as I can relate to it more since I actually interact with these
systems and people on it.

For example, I'm pretty sure I had read that the ISS was as long a football
field before, but it was a general fact. Now I can see how it can be a
factor in accessibility while living and working there, and even in ham
radio access. Very cool.

PSAT digipeater has been turned off.  The spacecraft has entered safe mode
now several times due to low power.  So we will keep it off until
conditions improve.  Do not use the PSK31 transponder either.



We were so accustomed to excess power during the previous full sun period
that we had evertyhign on? 95 miunte orbit 100% always in the sun.



But now we are in a maximum eclipse period with only 59 minutes in the sun
and 36 minutes in the dark.  Cleary that is only 61% of the power we had
before!



The times of lowest power of course are just before dawn.
