I am pleased to report that HQ8R will be QRV on the
satellites from Swan Island, grid EK87, from March
15-23. See http://www.hondurasdx.com/
I'll be taking my FT-817 and an Arrow antenna. Time
permitting, I will also try to make a few contacts
before and after the expedition from the Honduran
mainland, EK55, EK65 and EK75. Weather permitting, we
may also try to give out EK76 from the boat on the way
to and from the island.
73, Bill NZ5N

Mak,
I can assure you the patch *IS* correct.
The photo is taken from the rear, what you are seeing in the photo is the 'rear' of the reflector and the back end of the gold SMA connector.
The radiator - (hidden by the larger reflector, in the photo) - is connected to the pip of the SMA connector and is mounted 3mm 'above' the reflector.
The radiator is 'cut' for 2401Mhz and is made from silver plated brass sheet ... bas is the reflector.
I think what may have fooled you is ...
1) Not realising you were looking at the rear of the patch.
2) The fact that my reflector is square, not round.
The G3RUH design uses a round reflector, the K3OE uses square.
As far as I can assertain there is no practical difference between the designs.

Hi John,
I read your post but I am afraid that, your
PATCH is not correct. Sorry if I am wrong, but due to non-clear photo I
can see
on the Left-UP part of photo ONLY
the "drive element" of Patch (the square-piece with cut-corners ) without
the "circular piece" behind of drive-element which acts as
reflector.
As I see also in your photo, the chassis-connector is
mounted on this square piece and not to the
circular reflector.
If that is not my... illusion, that is not a
correct Patch. I send you a clear photo to take a view how is the
complete Patch by viewing that from the front-side.
73, Mak

OBSERVATIONS FROM
NORWAY. February
2008.
Based on SV1BSX's comments about receiving a *THUNDERING* signal
from AO-51's S-band transmitter on a patch antenna 'without' a reflector - I
decided to chuck together a few components to see if somebody as 'thick' as
LA2QAA could manage it.
The attached pic is the ... 'fruits of LA2QAA's
labour'.
Starting at the top right we have a silver covered brass plate
2.4Ghz patch antenna (note the real gold SMA connector, folks) mounted 3mm
over a (ditto) groundplane, via a short length of high quality (fell off the
back of a North Sea Oil industry lorry) coax feeding the input of a 2.4G
70 70cm converter ... the output of which goes to the IC-E91 dual mode
handheld and a pair of 'cans' ... (headphones, to you!).
To the right
of the IC-E91 is a Nokia N70 mobile phone - (not shown in this pic because I
was using it to take the picture) - with the 'SATme' tracking software ....
which is very !! useful for tracking S-mode signals from LEO birds with the
'slight' doppler thus received.
The phone also contains a compas as
well as GPS software so there's no excuse for ... 'but I can't find north' ...
(not always easy in 3 feet of snow, null visibility and cloudy conditions) ...
and there's *NEVER* a brownie or a girl guide around when you want one.
S-band signals in those conditions? ... you'd be surprised - we don't
all live in satellite friendly climes you know.
Mak (SV1BSX) is right.
A 60cm dish is overkill for AO-51 mode-S ... though of course, there are!
those that think you need a personal
Jodrell Bank to hear anything above
70cm.

I am offering this up for sale here before I put it on eBay.
I have an OLPC to sell. I am not a unix/linux guru and have no idea how
to get the machine to do more than what comes pre-loaded. I connected to
my home network but using it to surf the internet is just not something
I need it for.
The OLPC comes with the ac adapter and an instruction sheet. I will sell
it for the $200 that it cost plus $20 shipping in continental U.S. only
(2-day Fedex).
**** Reply directly to me and not to the list ****

Really the S transmitter is very strong
It's easy to receive even with a
simple doublequad with reflector
But the speed of the Doppler shift is amazing!

I need a little help using pb/pg with GO-32 to upload/download files.
I'm a linux guy, I have a linux machine running ax.25 software, talking
to a TNC in KISS mode hooked up to my radio. Using the ax.25 utility
'listen -a' I can see GO-32 transmit packets when it passes overhead.
I can sort of flail a bit with "pb" and it transmit some packets to
GO-32 and even occasionally see GO-32 send back a packet with my
callsign, so I'm pretty sure that the radio and low level link are at
least sort-of working.
Can someone give me a little guidance about how to use pb/pg to download
a list of files, download a particular file, and upload a file. My aim
is to upload a file, then download the file on a later pass, but I can't
seem to figure it out on my own.
thanks,
jeff AD6EO
.. the accepted term is "CQ" not "listening"...
Accepted by whom?
I have never heard that using a Morse Code code on a voice system was accepted by anyone of importance.
I haven't seen any reason here yet to change the presentation I've been giving for years now...described on the amateur radio pages at...
