First, almost every mag mount will scratch your car - something never
printed on the packaging.
Second, any "vertical" antenna for the V/U FM sats will have a transmission
(and generally receive pattern)
that is perpendicular to its mast. So, think about it: A GREAT pass of 90
degrees goes overhead - your
vertical is valueless during the middle of that great pass.
SO ... Some are "compensating" by purchasing better antennas (i.e., more
gain) and pumping out 20 or
50 or 100W. Awful wasteful, IMHO - since we both know we're workin' these
birds with a Watt or two.
Ideally - in a car - I would think that stopping and parking and getting a
vertical perpendicular to the
orbit of the satellite would give best results. I have a Larsen
KG-2/70-CX-PL whose whip I can adjust about
20 degrees off normal, and hopefully be travelling in the correct direction
to work a bird or two.
But if you're going to stop and park - then just whip out your homebrew Tape
Measure Beam from the trunk,
and REALLY make some contacts!
BUT - You told me you wanted to keep moving with the familt in the car. So ...
Then maybe a Larsen mag mount - which you can purchase an extra whip. And
bend - er, I mean,
"re-form" that whip right at the base so that it is about 20" bent.
Keep extra allen keys in the glove compartment - to loosen and re-position
the whip. You might look a little
funny driving down the road with a "bent whip." But you'll be more
successful with the FM birds!
Got kids who are on the 'Net already? Plan your rest stops/meal
stops/bathroom breaks around the satellite
passes! Give 'em maps ... sat pass times ... have 'em figure out
approximately where they'll be at what time ...
Sure beats having them play video games or watch TV in the back ... (grin)
Suggested items:
Larsen NMO-MM-R-BNC - a solid, round mag mount with NMO connector for an
antenna. This particular
one terminates in a BNC-MALE. They have other models terminating in other
connectors. Or get one that
terminates in the FME system, and you can then purchase adapters for SMA,
BNC, PL - whatever.
Larsen NMO-2/70 BLACK - very good dual-band NMO base whip.
Larsen W270B - just the replacement whip.
HRO carries all this. Snag the Larsen Amateur Products .pdf catalog at ...

Hi AMSATERS
The kids at Paul Breaux Middle School in Lafayette, La are forming a school
radio club. Their first meeting will be at 10:20 AM CDT Thursday September
15th. If you could tune in on EchoLink node 370324 (the 146.82 W5DDL
repeater) at 10:30 for a quick demo it would be helpful. The younger you
are the more the kids will identify with you, but old guys like myself it is
O.K. If you can meet us on the air pleas reply to this email.
Thanks

Mike,
Had it just come out of eclipse? I have seen no Kursk frames when it just
came on just after eclipse...I think the Kursk Experiment isn't running
quite yet, so no frames to xmit.
So yes, I saw this yesterday :)
Also, to confirm W5RKN---I have seem some "all 0" frames too...you can hear
hear it on the audio actually :)

Hi all,
I'm trying to digipeat through NO-44 but to no avail. Using a Kenwood
TM-D700 on 145.825MHz and ARISS,W3ADO-1 as the path. I've tried
different paths and still no go.
I see stations in Japan show up on
http://www.findu.com/cgi-bin/pcsat.cgi only minutes after a pass over
Australia. So I'm thinking if they can, why can't I. Do I need any
other settings?

Hi Andy,
The OCXO should be fine to drive either DEMI or DB6NT transverters.
On the VFC pin, they usually tune over a range 0-5v. Sometimes you can just
let them float, but it's usually better to tie them to a stable voltage
source. You really need to measure it to find out. I personally would not
let the VFC pin float.

Hi,
Thanks for reading this message.
Because I do not have enough serial ports in my computer, I bought a USB
to serial converter from StarTech. It is a 4-port version. (ICUSB2324X)
I switched my FT-847 from a buildin serial com1 to com3 (the USB to
Serial one.)
Everything seemed okay, until I wanted to use SatPC32. When I start
SatPC32 the CAT option lighstup in my FT-847 display and then I get the
error message: "Error reading comm device."
I have looked around to see if there is a setup option that can solve this,
but I am unable to find one.
Is there anybody out there who knows of a way to solve this? Other programs
work fine, for example HRD 5.
Here some hardware information:
- Using a HP Compaq 3GHz P4 HT with 2G memory running Windows XP - EN SP3.
- Yaesu FT-847
- SatPC32 V.12.8a (2009)

Hi Jan,
Be sure the baudrate is set correctly in your SatPC32. It's under
Setup > Radio Setup then in the dropdown list next to your radio,
change "Model" to "Baudrate" and make sure it matches what your radio
is using. It's not always obvious that the little drop-down there has
a second menu setting.
Also double-check your USB-serial converter settings (Windows Device
Manager, right-click each port and choose properties) to be sure the
baud rate and stop/start bits are all OK just to be safe.

Content-Type: text/plain; charset="us-ascii"
Everyone's comments are correct and valid within their context. But the
original question was optimizing for the casual mobile operator in motion.
So here are some additional considerations...
> Second, any "vertical" antenna...will have a [null overhead]
> So, think about it: A GREAT pass of 90 degrees goes overhead
> your vertical is valueless during the middle of that great pass.
True, but when we put some actual numbers on that, the loss is quite
insignificant. Using AO51, only one pass every 5 days goes above 82
degrees, and the total duration above 82 degrees is 24 seconds, out of all
in view times. So we agree, the antenna is valueless, but for under 1% of
the time. The tradeoff is that it is 3 dB better most of the rest of the
time...
The measured elevation profile of a 3/4 wave vertical (a 19.5" whip on the
435 downlink) is shown 80% down the page http://aprs.org/astars.html. The
overhead null is only 10 dB down at 82 degrees... BUT the satellite is 10 dB
closer at that point, so you still hear it almost the same as when it came
above 25 degrees. So you get full sky coverage above 25 degrees > 99% of
the time with the vertical.

Yes, good idea, but now there is some directionality and so the car needs to
remain pointed towards the satellite during the pass. Otherwise there is
still the null, it is just in a different part of the sky.
> 1. If the satellite is circular polarization the 19.5 " whip looses 3 dB
of gain.
Yes, but most people have observed a polarization shift during overhead
passes. And in that case, the loss of a circularized antenna is much worse
than 3 dB... usually a complete fade. SO I agree, a circular antenna gets 3
dB better half the time, and much worse the other half the time. I prefer
the simplicity of the whip that does not give up more than 3dB no matter
what the polarization is. Mounting a quadrifilar on the roof of the mobile
is also problematic.
> 2. The common Quadrifilar Antenna is 1/2 wave 1/2 turn.
> The 1 wavelength, 1 turn Quadrifilar Antenna has its

But it is still only a 3 dB gain antenna out there, and so it is not going
to hear the satellite down on the horizon anyway because the satellite is
10 dB farther away and usually blocked for the mobile. So having gain on
the horizon for a mobile omni antenna is wasted. It either is not enough or
it creats additional nulls higher up. Better to move that gain higher up
but smooth where the satellite is closer and then have good contacts, than
waste gain where it is already insufficient or problematic.
Just different perspectives, but the devil is in the details...

Hi Jan,
does CAT control work correctly if you connect the FT-847 to the physical
COM 1, particularly with SSB sats (FO-29, VO-52, AO-07)? The program reads
the RX VFO frequency once per second to allow transparent tuning (that means
you can tune the radio with the VFO knob).
I suppose your FT-847 is not one of the first on the market? These
first radios didn't allow to read the VFO.
Is there a difference between SSB sats and FM sats?
CAT control of the FT-847 works flawlessly for many years
already. I use it with physical ports (built in and via PCI card) and with
my 4-Port Keyspan USB-to-serial adapter and it works also with a Prolific
and FTDI single port USB-to-serial adapter under Windows XP, Vista and
Windows 7, 32- and 64-bit.
My settings in menu "Radio Setup": CAT baudrate 57600 (at the radio menu
37), CAT delay 20, option "Satellite mode" checked, other options unchecked.
My previous mail to you was bounced by the mail delivery system. So, I send
it also
via AMSAT-BB.

Thanks to everyone for the Sat QSOs during my trip the past week.
I had a great time viewing scenery that I hadn't seen in a while and
working the Sats!
There were even QSLs waiting for me when I arrived home yesterday
evening!
If you haven't sent one yet, SASEs and return cards are certainly not
necessary. I'll eventually get cards out to everyone, and LOTW updated.
Thanks again....ted....aa5ck

But this is not what a 19.5" whip does. The 1/4 (3/4) wave 19.5" whip does
not have gain on the horizon (so it is rarely used for terrestrial mobile)
but its pattern is ideal for satellite work on high passes. It does NOT
then have a null in its pattern that causes the "crappy" contacts, and it
does have plenty of gain above about 25 degrees.... and it is a smooth
pattern.... not like the multi lobes of a standard mobile gain antenna.

Hi Bob,
This is off topic and didn't want to start something on the list... :), but
can I convert my current magmount gain antenna simply by replacing the whip
or is the "gain" stuff in the magmount itself? If so, would any thin steel
rod do? I'd really like to give this a try!

When I was mobiling a lot I used quarter wave antennas on 2M
and 70CM. Preamp on the receiver,and just a dual-band mobile FM
rig, and at times just a dual band HT in the car. Receiving was the hard
part, but at the time UO-14, AO-27, SO-35 had pretty good downlink
signals.
And as far as a mag-mount goes, Anything that doesn't blow off the car
at 70 MPH will be fine !
73,
John, K6YK with about 4,000 mobile QSO's in the log.

Message-ID: <4E71D907.3060103@xxxxxxx.xxx>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
The company I work for gave me a 16GB iPad for work and I can pretty
much put anything I want on it.
There are not as many apps designed for the iPad as there are for the
iPhone (iPhone apps will work, but they're "screen space" small).
However, I found HamSatHD. There are no reviews on the App Store so I
was wondering if anyone here has used or is using it?
I just want to track satellites not control anything while out-and-about.
Developer webpage is www.vosworx.com.
Thanks,

Message-ID: <4E71DC19.7000804@xxxxxxx.xxx>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
I have successfully built and operated my G59 transceiver with GPA10 10W
amp (http://www.genesisradio.com.au/) for 40m JT65a contacts to VK2, 75m
voice contacts in the States, and everything in between.
At some point in the past, some group (TAPR?) had a 2m SDR transceiver.
I have no idea where that information might be.
Does anyone here use SDR for their satellite operation? Maybe using
Flex radios or something else? I don't know that it would matter on the
FM birds, but it would be nice to be able to see the spectrum on the
linear birds.
Thanks,
Joel - W4JBB
