We should be crossing into FJ07 shortly, around 22/2300Z. I'll be on the
AO7 pass that rises locally at 22/2302Z, assuming AO7 is still in Mode
B. We will be in FJ07 for three or four hours, so the VO52 pass at
23/0149Z should be good for that grid as well.
I expect to be on from FJ08:
FO29 - 23/0813Z
AO51 - 23/0853Z
FO29 - 23/0958Z (possibly)
AO51 - 23/1032Z (possibly)
My ship received our transit schedule for tomorrow. Traffic has to move
slowly through the canal, so it will be an all-day transit. Barring high
winds or bad weather, I'll set up the step ladder satellite station on
the flight deck and leave it in place all day.
1345Z / 0845 LT - Arrive Miraflores Locks (east side, right hand)
1450Z / 0950 LT - Depart Miraflores Locks
1535Z / 1035 LT - Arrive Pedro Miguel Locks (west side, left hand)
1620Z / 1135 LT - Depart Pedro Miguel Locks
1950Z / 1450 LT - Arrive Gatun Locks (east side, right hand)
2145Z / 1645 LT - Depart Gatun Locks
Evidently there are three sets of locks; I was only aware of two! I
don't know if the Pedro Miguel Locks has a web cam; probably not since
these locks are immediately after the Miraflores Locks.
Looking at SatPC32, there's a VO52 pass occurring shortly after we enter
the Miraflores Locks and an FO29 pass as we hit the Gatun Locks. I
should be able to make both passes; it would be fun operating on camera!
Also, we'll cross into FJ09 at the Miraflores Locks, possibly during the
VO52 pass at 23/1355Z.

I'm no longer active on satellites and have some satellite-related gear
that is surplus to my needs:
1 ea. Symek TNC31S - $275 OBO +shipping (and PayPal fee if applicable).
Comes with the 9600 and 9.6k/38.4k modems. I'd prefer to not separate.
>From what I read on the Symek site, both are out of production. I think
it was UO-36 on which I used this.
1 ea. Icom AG-25 - $125 OBO +shipping (and PayPal fee if applicable).
Works with the IC-821 and FT-847 (I do not know about other radios).
I might have a pair of mode J antennas too. I need to contact the
person who was going to purchase them.
Please contact me off-list at w4jbb(at)charter.net

Patrick is one amazing gentleman. I had already harassed him for some radio
tips earlier in the day, so I posted this to the AMSAT-BB, not wanting to

deja vu for me. I worked there 1976-1979. Of course lots has
changed. I tried to get a tour in Sept. 2001 but they were
"locked-down" after 9-11. I did get a tour of Goldstone, but only
because I wrote that I was coming, in advance, and because I used to
work there 1971-1976. The gal that gave the tour was one of the
trainees that took the program (in 1978) that I established in
1974. That was special.

Hello All
I acquired a Cushcraft 416-Tb antenna,the so called phasing harness was in
bad shape,so I am going to make a new one for it.
I could copy the original one,but yes I am making it hard on myself and
decide to calculate the proper cable type and length,and to do that I need
to know how the antenna actually works.Here is my problem ,the 2 driven
elements have a balun to each of the Tmatchs to make the impedance 50 ohms
on each driven element.The original phasing harness is 2 piece of 75 ohm
aprox 13" that goes to each driven element and the a so239 connector on the
other end of the harness is the 50 ohm feedline.I originally thought this
was a matching stub,but when I do the calculation for the matching
stub,should only be aprox 4" to each driven element.Am I missing something
here,how are they able to do this,does anyone know this antenna and how it
works.
Thanks to all who read and respond in advance

Hello Howard,

Hello David
I did think about that also
I also though maybe the balun didn't make it 50 ohms but maybe a much high
value
But when i fed the ver driven element with 50ohm feed line and checked the
swr with just a meter it was ok so that ruled that out.
I realize the circular porization was done by the physical location of the
driven elements,
Thanks very much David
Howard

Hi!
I will have an AMSAT table at the Radio Society of Tucson's spring
hamfest on Saturday, 26 March 2011. The hamfest will be at the usual
spot for hamfests in that city, in the Kino Sports Complex - along Ajo
Way, east of I-10 and the baseball stadium (previously Tucson Electric
Park, now Kino Veterans Memorial Stadium). There is a map of the area
showing the hamfest location available at:
http://www.rstclub.org/sites/default/files/HamfestMap11.jpg
The hamfest officially starts at 0700 local (1400 UTC), but - as with
most hamfests in Arizona - there will be people roaming around an hour
or so earlier. WD9EWK will be on several satellite passes throughout
the morning for demonstrations from approximately 1300 UTC, including
AO-7 passes if it is in mode B (it should be, if the current pattern
continues). The hamfest site is in grid DM42me.
Depending on how long I stay in the Tucson area after the hamfest, I
may make a drive to one of the different boundaries in southeastern
Arizona for a few hours to work satellite passes before returning home.
I have been to the DM51/DM52 boundary (along US-191, south of I-10 near
the town of Sunsites in Cochise County) on the last couple of trips to
that area, and it has been almost a year since I last visited the
DM52/DM53 boundary (along US-70, northwest of Safford in Graham County).
The Arizona/New Mexico state line along I-10 (grid DM52 only) is also a
possibility. Whatever direction I go, I should be visible on APRS at
(among other places):
http://aprs.fi/wd9ewk-9
If you have a preference on which of these boundaries I should visit,
please e-mail me directly. I can't guarantee I will honor all requests,
and really can't do that given the distances between these points. It
helps to know what others might be interested in working. Some have
already worked me in all 3 of these locations during my past trips.
Whether you work me at the hamfest and/or wherever I go afterwards, I
will be happy to confirm any QSOs with QSL cards. There's no need to
first send me a card or SASE, just an e-mail with the QSO details. I
will take care of sending a card (or cards) out. I will also upload
my QSOs to Logbook of the World.
73!
