Some more FUNCube dongle results:
(not much new information, just want to share my few hours
time today to spend on the FCD which I really enjoyed)
Using 2x6 elements 145 MHz:
- VO52 USB downlink great, with and without preamp
Using 1x12 elements 435 MHz
- AO51 FM downlink great with preamp, without noisier
- HO68 CW beacon great with preamp, good without
OK. So with the normal antennas the FCD works great.
Time to try thew absolute minumum: Outside in the garden, laptop
plus a simple vertical for 145 MHz; ISS packet: nothing heared/seen.
Was a surprise to me, as ISS is normally extremely strong.
Also tried AO51 FM with just a dipole outside: nothing heared/seen.
Both passes were >80 degrees elevation.
So for now I guess you need either a beam or a preamp.
Then again, the unit is the size of a USB memory stick and
has a range 60MHz -1.7 GHz - no complaints !
Overal I am still very impressed. The dongle connected to my
normal antenna system (beams + pre-amps) gives great results.
Just listened twice to a VO52 pass, and listening in USB was very
comfortable, audio sounds very nice until 0 degrees elevation
(using WRplus).
Amazing to be able to watch the entire downlink spectrum, and
see a few QSOs in parallel, seeing multiple stations tuning (their
signals going from left ro right and back until they hear themselves).
Of course everyone else had SDR for satellites already :-) For me
this is just amazing. Great work by the FUNCube Dongle team.
We often see discussions on how to get SSB for a few $'s and start
to compare various conventional transceivers. Well, the FCD is surely
an option to reduce cost on the downlink: all mode / all bands.

Folks,
If you have one of these:
G6LVB FCD
http://www.funcubedongle.com/
You really ought to consider getting one of these:
G0MRF Signal Generator
http://shop.amsat.org.uk/shop/article_6/2.4-GHz-Signal-Source-Kits-by-G0MRF.ht
ml?shop_param=cid%3D8%26aid%3D6%26
(with some more details here: http://g0mrf.com/source2.htm )
I have a signal source board from back in the AO-40 era with a crystal at
96.019 MHz. It has proven very helpful as a continuos test signal source
for a wide range of frequencies for the FCD. Beats ker-chunking local
repeaters :) You can adjust various FCD parameters and see the impact, etc.
The current crystal (96.013 MHz) is just a bit different than mine (96.019),
but it would do the same thing...
Harmonically, it works out like this:
*note--if you have an antenna connected, keep in mind that fundamental
frequency is probably right near a STRONG local FM radio station ;) so the
noise floor might be quite high at 96.019 MHz! That one took me a while to
figure out...
Xtal Multiplier Output in MHz
96.019 0.667 64.013
96.019 1.000 96.019

Thanks, Gordon. You are too kind.
You won't believe it but that little 3-element hand-held beam is still in
use today (I built it over a dozen years ago). I used it Friday and
Saturday while mobile in Texas for two passes of AO-51 (I keep saying I am
going to replace the aging RG-8X coax, but just never get around to it). I
have an FT-100 in my truck and use an MFJ duplexer to split the signal to
the 70 cm beam and a 2 m vertical on the back window. I operate split mode,
so it isn't the best setup--but it works (besides V/U, I can also operate
V/S and L/S, using hand-held antennas out the window... and even U/V with
whatever I can hear on the vertical).
I was mobile and inadvertantly stated I was in EM10, when actually I was in

Hi Jerry,
I built a couple of your Handi-tenna three-element yagis for 70cm, one
for myself when I was getting into satellites first and a couple for
other people. They work great and it's a nice repeatable design,
guaranteed to work if you build it right. I've had QSOs through AO-51,
SO-50 and the ISS with mine, as well as a lot of terrestrial low-power
work.
Thanks for such a simple but significant contribution to amateur
satellites ;-)

Jerry, your "Eggbeater-II" antennas are responsible for me realizing
that I really _could_ work satellites without spending a ton of money.
I've built several of them, and as long as I followed the instructions,
they worked great.
I won't go into the pile of copper wire and PVC pipe that resulted in my
trying to "improve" them!
Good to see you're still around!

I've ran several passes today on AO-27 and AO-51 with the FunCube Dongle
(FCD) as my receiver. I'm also using Mike, DK3WN's Funcube Dongle Doppler
correction program.
Below are two links to a couple of screen shots. The first is WRPlus, the
software I use with the FCD (there are others). You can see the AO-51
downlink clearly. This was a 15 degree pass from here in Vermont, FN34im.
http://www.burlingtontelecom.net/~n1jez@xxxxxxxxxxxxxxxxx.xxxxxxxxxx.xxx
The second screen shot is the software running behind WRPlus. Top left is
the FCD Tuning Program. It's partially covered by SATPC32 in the upper
right. In the lower right is the FCD Doppler correction program sending
frequency correction to the FCD tuning program.
http://www.burlingtontelecom.net/~n1jez@xxxxxxxxxxxxxxxxx.xxxxxxxxxxxx.xxx
I need more screens and a better video card.
Thanks for those who contacted me. If I sound a bit distracted at first it
was becasue the first time I keyed up, I forgot that when I heard my
downlink it would be delayed significantly due to the DSP processing of the
FCD. The delay reminded me of working HEO!

Mike,
Nice. Yes, the delayed audio on your downlink is funny the first time or two!
Now, run some ISS packet with that setup! All you have to do is also run
AWEPacketEngine and UISS with the APRS map and you'll see what mess your
monitor will be ;) Have been doing that lately...it's almost absurd how
many programs it takes...

I have discovered a pulsating tone (about 600 HZ) in my 910H receiver when I
am tuned to 145.900 MHz (working the Linear birds VO-52 etc). The tone
stops when I power off the G-5500/LVB tracker. All equipment is grounded
and ferrite core filters are on all of the cables to solve this problem.
Aside from moving all equipment across the room from each other, what might
I be missing?
Any help will be appreciated

Hi!
With the news last week that ARRL's Logbook of the World now supports
the VUCC award, I have started the work to get my satellite QSOs
uploaded to LOTW. As I previously mentioned, the ability to associate
up to 4 grids with a station location will make my work so much easier.
Grid-boundary QSOs won't require any extra work to upload. QSOs from
other boundaries will still require a little extra work to properly
represent them in LOTW, but that is a small number I can manage. I
just renewed the LOTW certificates for all of my calls, and they
dropped into my e-mail in-box this morning. Once I load the renewed
certificates into the TQSLCert program, I will take my spreadsheet log
and start making ADIF files for all of my calls and locations I have
worked from.
I have received QSL cards over the years where my callsigns have /P after
them, and a couple where the XE2 comes after my US call and not before it
as is it listed on my Mexican ham permits for QSOs when I was in Mexico.
Since I operate portable almost all the time, I do not identify on the air
as "portable" or "/P". If you have logged QSOs with WD9EWK (or my other
calls) with a "/P" in LOTW, you will need to correct those entries in
order to have QSLs in LOTW with me.
Based on e-mail exchanges with ARRL when I set up my LOTW account in
2008, there are 5 key elements that have to match in any two LOTW QSO
records to make a QSL. The call sign is one of those key elements.
The others are date, time, band, and mode.
I will soon upload satellite QSOs to LOTW for these calls:
WD9EWK (two QSOs from 2000, one from 2003, and a bunch since 2005)
VA7EWK (used on my July 2010 trip to Canada)
CJ7EWK (used on my November 2008 trip to Vancouver - CJ was a
one of the special prefixes available at that time to
Canadian hams)
XE2/WD9EWK (for my 3 trips to Mexico since February 2009)
I have also operated with other call signs in January 2007 (W7W) and
May 2008 (K7RDG). Since I do not hold those calls, I am not able to
upload anything to LOTW for those satellite QSOs.
QSOs made from other boundary lines - county, state/province, or
national - will require uploading two QSO records to LOTW by *both*
stations to confirm the contact from both sides of that line. Each
of my QSO records for these contacts will be from a station location
on each side of the boundary line. I have worked satellites from
these non-grid boundary lines:
Apache/Navajo county line in Arizona (August 2009)
Indiana/Ohio state line (several times since 2006)
Arizona/New Mexico state line (October 2009)
Illinois/Wisconsin state line (October 2010)
Canada/USA international border (July 2010)
Since the QSO records for the county-line and state-line QSOs would
have the same 5 key elements matching, I will vary the QSO time for
QSOs from one side of the county or state line by one minute (i.e.,
QSO at 2300 UTC from Indiana and 2301 UTC from Ohio). Otherwise,
the second QSO record with the same 5 key elements will overwrite
the first QSO record in LOTW with those elements. The Canada/USA
border QSOs won't have that problem, since the calls in the two QSO
records won't match (VA7EWK for one QSO record from Canada, and
WD9EWK for the other QSO record from the USA).
I still need to make my initial satellite VUCC application, but want
to get my satellite activity into LOTW so others may be able to use
QSOs with me toward future award applications. I've waited for VUCC
to be supported in LOTW since I first set up my LOTW account almost 3
years ago, and it is great that it has finally happened.
73!

Hi Marco, IZ5IOW
I believe that the best solution for your needs is to use a KR-500 with his
control box because it bear not too much in weight and has a 500 ohm
potentiometer into it that can be used in the future for the automatic
control of the elevation via your PC.
