Hi Guys
I am on my way to Aruba for the CQ WW SSB.
I will be QRV as Single Op All Bands as usual.
Saturday the 19th I will be in Miami. I will stay at the Airport Regency
Hotel
TEL 305-4411600. If any contester is around fell free to give a call.
Should be QRV from P4 on the 21st October. Qsling via CT1AHU.

Boy I really feel for you guys ( I'm closer to Europe than I am to most
places in North America) As a contester it has it's advantages,
as a dxer it's just QRM !
Layers ? What layers ? First there are the guys with beams , then there are
the guys with dipoles , then there are the QRP guys with Beams , QRP with
Dipoles , the occasional guy with some wire in his " loft " attic that is.
The 20m mobiles then the 40 m Mobiles and once in While the 80 m Eu Mobile!
Then finally there are the guys with Coat hangers lashed to the metal
railing on their apartment bldg balconies.
Yes I guess there are SOME layers !
My sympathies!!
>>>To those of us in the "true midwest" there are two layers of europeans.
>>>Those we can hear and those we can't.

Here's a scary scenario...

Subject: Hubble Follows Rapid Changes in Jupiter's Aurora
HUBBLE FOLLOWS RAPID CHANGES IN JUPITER'S AURORA
Hubble Space Telescope's sharp view of the rapid,
spectacular dance of luminescent gasses high in Jupiter's
atmosphere -- better known as aurora -- is allowing
astronomers to map Jupiter's immense magnetic field and
better understand how it generates such phenomena.
(snip)
The new Hubble observations simultaneously show warped
oval rings at the north and south poles (offset from
Jupiter's spin axis by 10-15 degrees), as well as an auroral
"footprint" created by a river of electrical current of about
one million amperes flowing between Jupiter and the volcanic
moon Io.
(yeah, that's as in "MILL-YUN")
(snip)
...auroras on Earth are
triggered by a barrage of charged particles from the Sun.
This process is different on Jupiter, although not well
understood. Fundamentally, the planet's immense magnetic
field, coupled with its fast, 10-hour rotation, helps
generate auroras that are 1,000 times more powerful than
Earth's spectacular light shows.
The situation is complicated by material released by
Jupiter's moon, Io. Scientists believe that volcanic
eruptions on Io churn out particles that become ionized,
expand radially, and are trapped by Jupiter's immense
magnetic field. These charges are forced to co-rotate with
the planet, creating an immense sheet of current that in turn
modifies Jupiter's magnetic field.
(snip)
Some of the material released by Io produces a fierce
current of charged particles. The particles become ionized
and are then drawn into Jupiter's intense magnetic field
along an invisible "flux tube," which bridges both worlds.
This creates small auroral spots just outside the ovals
around both magnetic poles. By studying changes in the
intensity of these spots, Clarke and his colleagues were able
to map Jupiter's magnetic field as Io orbits through it. The
scientists linked the spots to Io's "flux tube" because the
auroral emissions rotate with Jupiter while the spots remain
in a fixed location underneath Io.
"The size of the aurora at the magnetic footprint of
Io is 600 to 1,200 miles (1,000 to 2,000 kilometers) across,"
Clarke said. "If you were at Jupiter's cloud tops, under
Io's footprint, the aurora would fill the entire sky. You
would see an explosion as the gasses 250 miles above you
rapidly heated to more than 10,000 degrees Fahrenheit. The
aurora would speed overhead from east to west at more than
10,000 miles per hour (5 kilometers per second) because
Jupiter's fast rotation moves it rapidly underneath Io, which
orbits more slowly."

How'dja like to run DX through one a-them puppies? Kinda puts our
troubles in perspective, don't it?

You are absolutely right, Mario. Yaesu looked at all the RX mods they had
made to the 1000D and built the MP to that standard or better every step of
the way.
I'd agree that the TX section could still use a little tweaking, but the guy
who said the MP wont work with an Alpha 87 is just dead wrong. I've got 2
MP's of different vintage and 2 87's and they both run just fine. Even
unmodified,
the MP works fine with a properly adjusted 87. They did come out with a very
simple power control mod (cut a track and install a jumper wire) which fixed
any complaints in that department. However, I do agree the D's TX as a whole
is more solidly built (and of course puts out more power).
Someone complained about Yaesu service! I couldnt believe that one. I just
sent my MP in with several minor complaints and upgrades and they turned it
around in 1 week! I even talked to the technician twice during the process.
This 2 weeks before CQWW phone... yeah, that's TERRIBLE service!
Besides the nearly bullet-proof RX, I was sold on 2 things. It's small and
light enought to be DXpedition material and it's versatile. It's got all
sorts of options and flexibility, but the kicker for me was that it's set up
to run transverters for VHF/UHF. It's a beautiful IF radio for 2 meter
contesting in a "hostile" environment.
Lastly, I'd suggest to anyone that is going to post summaries please include the
ID's of the people responding.

I'm of to Caracas next week to participate in a planned M/S in the WW
SSB, from the island of La Orchila, off the coast of Venezuela. All
of the crew except myself are YV's. The only call I heard talked
about was YV10M (YV-one-zero-M) (but I haven't heard if the call is
locked down). If all else fails, we may be on as YV5A or 4M5X from
the mainland.

Aloha Mario,
Yes, also the RF preamp of the MP may be operator bypassed, or
set to operate "flat gain" across all HF bands, or only amplify
either the lower or upper HF bands. This flexiblilty certainly
helps to lower intermod distortion products in a strong signal
environment. Such problems are very common during contests
(or when rare DX is QRV) among amateurs who live in
near proximity to one another, such as a metropolitan area.
Fortunatly for me, I have not been faced with that out here
on this island. However, I believe the QTH area has been
discovered. I am told that an active DXer from Japan,
AH0A / 7A1AAA is building a (retirement?) QTH only about
3 or 4 miles North of me, and above me by maybe 400 feet
on a hill. His only problem there is going to be blockage by
the mountains to his North, which is our short path over
the pole to Eu and the Med. From my QTH, Mt. Kahili
rises about 5 or 6 degrees due North, for him it will be a
greater problem.
Anyway, my idyllic setting may become shared with another!
