Hi Ed / Dave / Group.
It seems a very long time ago now, but in the dim and distant pass ESA
approved a plan to have a permanent amateur station installed inside the
European Columbus module.
As a European (Well, on a little island over here) I'm almost embarrassed
to mention this because having spent a lot of contributors money...and a lot
of ESA's money on some very nice antennas, the organisers of this project
seem to have gone into hibernation.
Occasionally, you hear rumours of plans and rumours of rumours but the
reality probably is that they don't have the ability to do the job. - I always
think of the scene from Life of Brian where small ineffective groups sit
around plotting the overthrow of the Romans and just have endless meetings.
Sad.
Very sad.

no space-rated enclosure, no EVA.
Last time I propose this I was told to shut my mouth and go away.

I think the US itself declined to adhere to this for the latest DOD
global communications satellite. That being said, the FCC has requirements.

Thanks David,
The latest I heard was that AMSAT-Italy was working on a transponder
and the HamTV for Columbus. Maybe someone can get in touch with Gaston
Bertels, ON4WF (ARISS Europe) or whoever runs AMSAT-It and see what
the status is.

David, there is a packet radio station operating on 437.550 MHz in the
Columbus module, see
UHF Station on ISS Columbus module
http://www.uk.amsat.org/2472
Also the following from the AMSAT News Sevice (ANS) a couple of week ago:
+ Hardware proposal regarding the installation of a new Kenwood
D710 radio in the Columbus module.
+ Hardware proposal for new power supply for ISS-Ham operations
in the Columbus module.
+ Ongoing work with ARISS-Europe, AMSAT-Italy, ESA, and Kayser-Italia
for implementation of the HAMTV - Digital ATV with S-band downlink
from the Columbus Module. S-band ATV equipment would be required at
schools for use in video ARISS contacts.

Bob,
I have often worked the linear birds mobile using an FT-100 (Yaesu's similar
rig). Obviously, working a linear satellite in half-duplex mode is not the
easiests of ventures, but it is not all that hard either. FO-29 is the
easiest of the LEOs to work in this mode as it is easy to mentally adjust
for the easily estimated Doppler shift. I have also worked both AO-40 and
AO-51 using this rig in mode L/S (using a downconverter and a trippler for
the uplink). I find the easiest method is to find a clear spot,
approximately the middle of the passband, estimate the Doppler for the
uplink and call CQ, then tune around for someone coming back to me. This is
not perfect, and runs the risk of interfering with an adjacent QSO, but will
work in a pinch. Just set your rig to "split" and give it a try.
73,
Jerry, K5OE

NEAR REAL TIME REVIEW JUST GOT OUT.
I give it 4 stars. Lots of behind the scenes stuff. Shows about 1 minute
of him on the radio.
Pretty good music.

Subject: [amsat-bb] getting "cheep" on the birds! (Pun intended)
Message-ID: <4F1963A5.8090300@xxxxx.xxx>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
There seems to have been a rash of postings lately about how to get on
the the "birds" for "cheep" ( yes the pun is implied!).
IMHO cheap is not always equated with good. No one wants the "cheapest"
Doctor around or the "cheapest" lawyer or the "cheapest" anything.
With the demise of AO51 and the loss of its simple operating
characteristics, there has been a migration to the "less" popular
satellites. Most of the other FM satellites are no where near as "user
friendly" as AO51 was.
With people suggesting that people can get on to the satellites with an
inexpensive Chinese made dual band HT and a "telescoping" antenna and
nothing else, they are creating a perception that that is all you need
to have a successful satellite station.
Nothing could be further from the truth! AO27 has a 7 minute timer,
there are increasing numbers of people who will call CQ the entire
satellite pass over North America and never answer a single response to
their "CQ's", and for some unknown reason these stations NEVER have an
email address listed on their QRZ listing. Some of us actually use the
satellites and do not like it when operators have been told they do not
need a preamp or a good antenna or a good radio.
It is much simpler to get into the uplink of the satellite than it is to
hear it.
I wish some of the "self-proclaimed" experts would tell these people
that if they cannot hear themselves on the downlink that does not mean
that they are not keying the satellite.
If people are going to encourage people to get on the satellites, teach
them how to use the satellites, not how they can get on the satellites
for less than $100.00. They are getting on the satellite and causing
interference for those that have invested in the equipment to take
proper advantage of what the satellites have to offer.
Some of the people that are pontificating profusely on the subject of
operating "for cheap" I have never heard on the satellites.
Encouraging people to become active is one thing, but giving people the
impression that all they have to do is get a basic $80.00 radio and a
telescoping antenna and they will have a top notch satellite station
tantamount to turning an untrained Doctor loose to do surgery.
For those that want to encourage people to get active, how about
teaching or recommending proper operating techniques, before you tell
them how "cheaply" they can get on the satellites.
AO27 has such a short timer that good technique is paramount for getting
the best use out of it, and SO50 has plenty of "quirks" to make it a
challenge at times for the "seasoned" operator.
I hope some of those promoting their own ideas of satellite use on a
budget would spend more teaching rather than recommending how much money
they can save by getting the least expensive gear available.
good radio, receive preamp, decent antenna & Patience = a good beginner
satellite station!
If you can't hear the bird, doesn't mean it's not hearing you!
I am happy to speak to anyone that is interested in satellite
communications, you can check out my QRZ page.

Greetings from the frigid north country,
I have used my single IC-706MKIIG with the linear sats. Back in the day I
had a table full of receivers, transmitters, transverters, preamps etc to
operate full duplex on AO-10 and the other sats. Since I had not been on
the sats since then it almost seemed like cheating using the tiny
IC-706MKIIG. Immediately the disadvantages of not having a full duplex
station became apparent. Even though I had made hundreds of contacts back
in the day they were all full duplex. I seized the excuse to buy a new
radio and bought an IC-7000 to pair up with the IC-706MKIIG for full duplex
operation and have been very happy with the pair. The receiver on the 7000
is much better than the receiver on the 706 so I use the 7000 for receive
and the 706 for transmit. In my opinion most of the mysterious QRM on the
linear sats is due to not using full duplex. With the high doppler shift
and the narrow passband filters in most modern radios it is easy to call CQ
and not realize people are trying to return your call because you are not
listening on the "right" frequency. The fact that there are many expert
opinions on using doppler correction on uplink, downlink, both uplink and
downlink or none of the above makes it even more difficult. Obviously it is
possible to make contacts without full duplex but in my opinion it is more
difficult. Hopefully the Chinese will come out with a decent low cost
HF/VHF/UHF all mode radio with CAT control that will make it possible to
operate full duplex on the linear sats without breaking the bank or having
to resurrect some old radios.

Does anyone know if Hamstronics has made a UHF receive converter? The
currently make one for 2m, but I would like one to use for FO29, if
possible.
