Subject: [TransAtlantic] DXpedition to Gambia, West Africa
Message-ID: <CC595788E6834196AA673963B74D6F88@CASEYPC>




Hi all,

Via the VHF remailer, Arliss, W7XU, this morning, made the announcement of a
DXpedition to Gambia later this month. I've emailed him and he has
discussed, but not promised, the possibility of taking 2 meter equip. with
him. There is, as always, an issue with the amount of equipment a DXpedition
can carry to a remote site like this.

The path from Gambia to the Caribbean and Northern South America looks like
a very strong possibility at this time.

Are any ops in place if this DXpedition were to operate on 2 meters?

The path from Gambia to the (leeward & windward) Antilles and Puerto Rico
looked pretty good in the Hepburn forecasts of this past Friday, Sat, Sun.

Comments?

Thank-You
Mark, K1MAP



>>>A group of us (W0SD, W0OE, N0QJM, W7XU) will be operating from
C5, The Gambia, beginning some time on 25 June and continuing
through 6 July.  We will focus on 6m, with plans to remain on
50.103.  We will be running an amp and a large yagi from a
seaside location and will have a breakable beacon.

We don't know what our call sign will be yet.  Should you see us
spotted on HF at some point, don't despair -- there will always
be someone at the 6m position during waking hours.

Hoping to work many of you ...

73,  Arliss  W7XU

Subject: [TransAtlantic] MUF at 90MHz this AM. 2m double-hop e-skip possible?
Message-ID: <0539C822BB6E41739A59B9BE343FE2C1@CASEYPC>

This morning about 8-10am the MUF went above 90MHz here in FN32sb 
(massachusetts,usa).

I've been watching for propagation this e-skip season.

DF5AI and DK5YA have a lengthy paper on long distance 144MHz on DF5AI's 
website. In the paper they discuss theory about the propagation mode(s) of 
3500km+ QSO's during May-June-July of 2003.

The possibility of double-hop (or extended hop)2m e-skip, 2m e-skip combined 
with tropo and various propagation types are discussed.

Any comments on the possibility that double-hop 2m e-skip, or 2m 
e-skip+tropo is possible, or some type of propagation combining e-skip, 
tropospheric or ionospheric bending, ducting, or tropo-scatter, or any other 
type of propagation might lead to a contact between Europe and North 
America?

Subject: [TransAtlantic] 144 common freq for Europe & North America
	Trans-Atlantic monitoring?
Message-ID: <8FCA748E95A6423DB79F18C2C07D23CB@CASEYPC>

With the e-skip season in  progress and the tropo season approaching, having 
a common frequency where stations on both side of the Atlantic could monitor 
without interference might go along way toward completing a Trans-Atlantic 
contact on 2m.

If we had a common freq. that, in most cases, most stations would be able to 
leave on 24hrs a day, if desired, without interference, would be a good 
idea.

On this side, 144.260 is a good freq. We rarely use it for anything other 
than 10GHz liason during the 2-10GHz contest weekends, in Aug and Sept. It's 
away from normal SSB regional traffic, nets and bacons. But, the RSGB band 
plan shows it as being used for Emergency Groups. 144.250 has some nets, but 
144.265 or 144.270 or 144.240
might be OK also. Our beacons start at 144.275 and go to 144.300. There are 
some other possible areas: 144.320-370, 144.100-140.

Is there a freq that would be relatively clear of traffic on the Europe side 
that we could use?

Comments?

Hi,

yes 144.260 would be a good QRG also for all EU operators.
This QRG is normally free. 
I also had a major high MUF event a few days ago.
I had 70MHz open to W1 (FN43) and from the signal strengths
I would assume that the MUF must have been 90 to 100 MHz may be.
During such events I am always on the NA Region 2 6m ON4KST chat.
But I never find any station from NA east coast during such events
for immediate tests on 2m.
IMHO this is the only way for a 2m TA QSO.
Even the 4m openings are of very short duration and 2m will be even
shorter,
may be just a few seconds to minutes.
E.g. when I made my 4000km Es+Tropo QSO to Israel 2m was open 1 to 2
mins only.  
So, there is even almost no time for a phone call to get a station on
the band.
Instant action is necessary and the PA has to be ready :-)
I am always ready on 144 MHz with 100KW ERP and for sure
I have one of the best QTHs for TA propagation in Europe.
However, I can NEVER find a possible QSO partner from the US or VE
during promising events on 6m or 4m or when 2m is open to Azores
Islands.

More coordination, more interest, more dedication is needed,
otherwise a 2m TA QSO will never happen.
