Hi Alan,
I already have that website bookmarked! :) My concern is if something
changed it wouldn't be updated fast enough, not the blogger entries, the
status of the repeater, etc. Seems to me that last year and before, the
time leading up to FD there were more bulletins from reliable sources giving
a heads up about the possible activity from the ISS. This year it seems
mute.

Hi Jan PE0SAT, my emails are not getting through to you so I'll post here,
I have had some success so far,
I've made up two lengths of RG213 with 1/4 wave lengths of 75ohm cable on
each end. These are to run from the coax relay to the 145mhz Yagi's as the
ARRL drawing suggests. N type connectors are used on each end of these
cables.
I've tested this as a phasing harness and achieved around 30dB return loss
that's with the 75ohm transformer ends in a T piece and 50ohm loads on the
end of each cable.
This was tested on my HP8920 using a 50Mhz to 1000Mhz Narda coupler and am
happy with the results, so the phasing harness as it is, is centered on
145mhz with a VSWR of 1.06:1.
Next is the delay line, this has got to be an impedance of between 104 to
110ohms, as the antennas are between 52 to 55ohms now this is going to be
hit and miss, as you can't get 105ohm coax. However, you can get 93ohm and
what I'm thinking is to remove the center conductor of the coax and replace
it with a smaller diameter conductor this should raise the impedance of the
coax hopefully to around 105-110 ohms, thus achieving the required impedance
of the delay line which is called for in that circuit.
The 93 ohms is just too low and I've found with my testing so far it's
better to be on the high side of impedance than the low. The 93 ohms seems
to look like near enough to 75ohms and acts like another transformer
section.
So I'll continue on and keep you in the loop on success or failure.
Thanks for your mail and Best 73's
Frank VK5KV...

Hi!
Omar XE1AO, a regular satellite operator from central Mexico,
e-mailed me news of a special callsign that will be showing up
on the satellites between now and 31 August 2009. The call,
4C50C ("Four Charlie Fifty Charlie"), is part of the "Trabaja
Todo Colima" (Work All Colima) special event currently taking
place in the central Mexican state of Colima. This event is
commemorating the 50th anniversary of the creation of the J.
Roberto Levy radio club in that state.
During the months of June, July, and August, stations from all
over Colima have been on HF and the satellites, trying to put all
10 Colima "municipios" (municipalities, similar to counties in
the USA) on the air. On HF, the special call XE50C has been used
from different parts of Colima. Now, four hams (XE1AO, XE1ATZ,
XE1AY, and XE1J) have been authorized by the Mexican
telecommunications regulator CoFeTel to use 4C50C on the satellites
as part of this event.
Initially, XE1AO will attempt to put 4C50C on AO-51's evening
passes along with VO-52 and FO-29 evening passes. Omar and the
other 3 hams hope to expand the use of 4C50C onto SO-50 and AO-27,
plus look at passes at other times of the day during this period.
For hams outside Mexico, XE1J is the QSL manager for these special
calls. The Mexican QSL bureau will take care of QSL requests from
XE hams. Along with the QSL cards, there will be a certificate
available to stations that work stations in at least 7 of the 10
Colima municipalities and also accumulate at least 74 points based
on the location of the stations worked in Colima. Additional
points are available for working certain stations like XE50C and
4C50C.
More information (in Spanish) is available at:
http://arco.sat-xe.org/XE50C/XE50C.html
and also:
http://arco.sat-xe.org/4C50C/4C50C.html
For now, the 4C50C page is a mirror of the XE50C page. It will
be updated shortly, with new information related to the 4C50C
call.
Good luck, and 73!

Over grid FN26 there will be 6 available pass starting 0122 EDT on June 28
most of them will be on the night shift but some real good one
early morning the 28 until the last one 0919 EDT June 28
Just to remind that only ONE (1) satellite contact is required to have the
ARRL100 satellite bonus points. Never heard if AMSAT-NA will
also have his satellite field day but it's not helping the ARRL Field Day as
multiple QSO'S are allowed.on a very restricted satellite
aging fleet.
Not to mention there is about no rules who stands and it is not a friendly QRP
area... The moto is the bigger and longer CQQQQQQQ EEEEER.
It will be interesting to have some negative points for poor operating
practice? It's easy to spot and post but not too flattering for the
offending station.
Just to remind some offended virgin ARRL has his check log for numerous years
and no one complains. (Those on the check log could be...)
Happy field day it will be a whole week end of rain and heavy thunderstorm
here!

Yes Luc ... the first satellite contact made will earn that ARRL entry the
100-point bonus for a satellite contact.
It's also important to note that ARRL and AMSAT are only scoring one contact
each on AO-27 and SO-50. AMSAT Field Day rules permit one contact each on each
of the active transponders on AO-51. If the ISS is configured to be active
both in FM voice and packet, AMSAT also will score one voice contact and one
completed two-way packet contact.
ARRL Field Day rules stipulate only one contact per FM satellite will score.
I have sent you the 2009 AMSAT Field Day rules off the BB. I hope that proves
helpful.
Best of luck to all this Field Day - and please listen for W4G on all of the
satellites!
73,
Tim - N3TL (operating the W4G satellite station for Field Day)

Hi Art,
Glad to see ham radio (and K1JT) get the good publicity, but i think the
author is overestimating the difficulty of getting on EME. As Dave, W5UN,
says on his web page, anyone with 100 watts and a good 10-element 2-meter
yagi can do it.
