Thanks to all who have replied to my message concerning switching polarity. I
think I understand it now, somewhat ! While in Las Vegas yesterday, stopped at
AES and picked up the Satellite Handbook by ARRL, and that gave a good
description of it and other items I need to learn also. Thanks again to all.

Subject: [amsat-bb] Polarity switching question
I recently obtained a pair of KLM yagi's for satellite work. They both have
the KLM polarity switching box mounted and wired up. Since I havent put them
up yet, and not well versed in the subject, I got out my ohm meter just to see
what was what on this item. I noticed that both driven elements have continuty
to the center pin of the coax at the same time. I was under the impression
that the relay switched back and forth the driven elements to give either RH
or LH polarity. I havent applied the 12 volts to the box yet to check that
out, but was just curious. One thing I have noticed while using the downlink
yagi is that I get very little fade due to polarity when I turn the antenna. I
hope that is a good thing?? I havent checked the uplink yagi to see if it has
the same results.
I hope someone can enlighten me abit.

Has anyone seen the antenna for 2m in this monthsQST p. 30. Its a
omnidirection sorta a double diamond turnstile. I was wondering how
this woould work for the LEO Sats?? Would think it would be simple to
scale it down for 435??

I did see that, but it has very low angle radiation probably with a deep
null at higher angles.
It's advantage was that it has horizontal polarisation.
I can't help but feel a quadrifilar helix would be better There are some
designs out there and there is also an online calculator for the dimensions
for a frequency of your choice.

I have used the Quadrifilar Helix Antenna on Satellites with great success, as
suggested by David GOMRF. My antenna is here: www.stormchaser.cjb.net with a

Hi Norman,
This is a topic that surfaces every so often and is not an easy one to
answer.
So my two penneth worth is this!
If you are only interested in VHF and above, Satellites and terrestrial
work - the 910 every time.
If you want a shack in a box that can do (primarily) HF, then the TS
wins the day!
The reason I say "primarily" is that the TS exhibits a "birdie" right in
the downlink frequency for SO-50 which renders use of that bird more or
less impossible on that radio.
Its like trying to compare apples with oranges.
For sat work (for me) the 910.
For HF work, the Icom 756 Pro series. :-D
Others will give you different answers of course but the main factor for
me if I was buying a radio now would be the SO-50 "birdie" issue. It may
only affect one bird but there are not that many left up there and no
plans to get any more up!

Content-Type: text/plain; charset="utf-8"
UPDATE ? 16 July, 2009 ? 16:45 UTC
The K5E special event operation is off to a good start, with contacts in the
log on four different amateur satellites ? AO-7, FO-29, SO-50 and VO-52.
OTHER OPERATORS
In an attempt to cover as much of North America as possible, three operators
have volunteered to assist in the K5E Satellite Special Event. They will ID,
per information I received from ARRL, as:
AA5PK/K5E
K8YSE/K5E
WA4NVM/K5E
Contacts with these stations are valid to claim a Special Event QSL. Please
send ALL requests for QSL to N3TL, and please include an SASE.
Operating Schedules: Here are the operating schedules for these stations. I
will post updates as necessary:
AA5PK/K5E will operate the following 10 passes (times noted are mid-pass for
his location):
2009-07-17 01:03:08 ECHO (AO-51)
2009-07-17 02:27:24 OSCAR 7 (AO-7)
2009-07-18 01:27:23 OSCAR 7 (AO-7)
2009-07-18 02:03:03 ECHO (AO-51)
2009-07-18 22:24:59 EYESAT-1 (AO-27)
2009-07-19 01:23:22 ECHO (AO-51)
2009-07-19 02:20:31 OSCAR 7 (AO-7)
2009-07-19 16:41:05 JAS-2 (FO-29)
2009-07-19 21:56:23 EYESAT-1 (AO-27)
2009-07-20 00:43:51 ECHO (AO-51)
On the passes above, AA5PK/K5E will be the ONLY K5E Special Event Station.
K8YSE/K5E will operate from the morning of July 21st through 0359 UTC on July
22nd as the ONLY K5E Special Event Station active.
WA4NVM/K5E Will operate form the morning of July 22nd through 0359 UTC on July
23rd as the ONLY K5E Special Event Station active.
NOTE TO ALL: Only 1 QSL card will be issued per valid amateur call sign.
Multiple contacts on the SSB/CW satellites (AO-7, FO-29 and VO-52) shouldn?t
be a big deal because those satellites aren?t too busy ? but the 1 QSL per
call rule still applies. Especially on the FM satellites (AO-27, AO-51 and SO-
50), please only one contact (all three satellites combined, not per
satellite). This will enable the K5E and /K5E stations to work as many as
possible. Thank you!
I will post additional updates as warranted, and also will update
www.qrz.com/k5e. Please see that Web page for full details on the special
event.

Add AO-27 to that list!
Also, and this is something that I will never understand why they
failed to do this; the 2000 can't send 12 volts up the coax line for
preamps, the 910H can. While there are other methods of supplying
voltage to preamps, it's nice to have it built in.

Whoa there hoss! :-) That's a little misleading. There are at least three
microsat sized satellites completed or nearing completion with FM repeaters
and/or transponders on them. Kiwisat, CAS-1, and SumbandilaSat. Sumbandila
is set to launch in August after a several year delay. I think CAS-1 is
ready to go this year as well if I recall correctly. I have no doubt Kiwisat
will fly either, in fact I've personally donated directly to AMSAT-ZL to
help make that happen.
Historically, there have been times when we've had much less to choose from
in orbit as well. It's not all doom and gloom.
I'm going to be updating the Future Projects page on the AMSAT website over
the next few weeks while on vacation. We'll get some newer information and
current links up on these new sats then. Projects can send updated info
directly to me at ko4ma@xxxxx.xxx .

Drew just e-mailed me about my comment:
/
"It may only affect one bird but there are not that many left up there
and no plans to get any more up! "/
and that that might be misleading!
I am happy to correct my statement by saying that what I was referring
to was the easy sats, the FM voice, 2m up 70cm down or 70cm up 2m down,
that everyone cuts their teeth on!
Drew has pointed out that Sumbandilla is V/U FM, CAS is V/U FM and
transponder both, and Kiwisat is U/V FM and transponder.
According to the AMSAT website, Sumbandilla and Kiwisat are both
awaiting a launch date and I have just heard that the other one is not
up there either but all are slated for this year.
On the basis that they actually make it to orbit (and that's a big
*"if"* of course, no sure thing in the launch business!), there will be
AO-51, SO-50, AO-27, AO-7, ISS, and the three to come. Throw in FO-29
and VO-52 (not strictly FM easy sats being as they are SSB birds) and we
might have 10 usable voice birds.
Take out the two "birdie" issue satellites from the *current* 7 usable
easy sats and the TS can not work nearly 30% of the available easy sats.
Factor in that AO-7 is getting old, ISS is rarely in cross band mode,
and that brings the figures down to 5 working birds, three (or 60%) of
which the TS *can* work.
If Kenwood have fixed the problem (and I haven't heard that they have or
how they could retrospectively) and you want to get into serious
satellite work, don't hamper yourself with a radio that will not do the job.
I am sure someone will say that my math is wrong but you get the point.

SSB for me too, F0-29 & V0-52.
Can't raise any consistent enthusiasm for FM birds with the exception of our
friends up in the ISS.
I can have the same abuse much more easily on the local FM repeater. :-)
So the TS2000 has a birdie, OK, but for those that don't want all their eggs
in one basket it is very good and it doesn't need another mortgage spent on
a Hi-Stab LO to stop it roaming around on its own. Well at 1296MHz anyway!
