I did not see any thing eather in wv had my d700 runing uiview and the d7 in my room i have not heard ande for a long time but when i do i can get in. just useing two jpoles. i cant be thare "live" i have school and bob can u give my some rough times when ande goes over im in the eastern panhandel of wv 13 mi. south of cumberland or look for kd8atf-2 on findu. 73 kd8atf

I am waiting on a well-used older FT-817. It's probably not optimal, but
it's an all-mode 2m and 70cm rig. I guess these days it's the most
affordable (cheapest) all-mode setup. I'll just have to see if it serves
better on the TX side or RX side. Downside to TX is only 5W. Downside to
RX is that it's an early non-DSP model, so no NR, and limited SSB
filtering (if any?)
Wayne Estes replies:
You can install a Collins SSB filter in the FT-817. That improves audio
quality on both transmit and receive. The improved selectivity isn't
really needed for satellites because ham satellites are incapable of
producing strong adjacent channel signals.

Special ANDE Operations Tues/Thurs 28/30 August:
Eastern USA Morning passes:
On Tuesday, Naval Academy stuents will operate ANDE to gather
statistics on the success rate of the APRS mission. We invite
participation, attended or unattended IAW these guidelines:
1) Tracking Base stations set 5 minute rate
2) 50W mobiles set 3 minute rate
3) 5W HT's set 1 minute rate
Do not TX more often, as it will mess up the statistics. Would
be nice if you put your station info in your posit text so we
could confirm the validity of the statistics of your transmit
rate, something like:
"Base=5min +10 dB"
"50W =3min w 5/8ths"
"HT=1min w 19" ant"
On Thursday, we may activate the packet to voice synthesizer.
If so, then we will tell you what to do then.

Greetings
Happy to report I worked joe K3SZH on a western pass of Oscar 7 orbit number 50,000
Only heard one other station in 6 land.
Not many people on ao-7 and hamsat, usually only one or two other people.
Save your bucks for some used all-mode rigs and you can get on. I'm surprised there are few HEO
equipped stations around, why wait?
Thanks, patrick n2oeq
John this is the grids that I still needed in case you want to know
NV DM19-DN00-01-21
CA CM79
OR CN72-93-94-95 DN02-03
Many thanks for DM28 , unfortunately I lost you in the others :-((
Whoe are close or know who live in that grids ???

when doing a phase line for a crossed yagi to give it a circular
polarization. how do you make sure that you have electrically 1/4
wavelength of line? it strikes me that this would greatly matter or else
the antenna wouldn't be fully circularly polarized.

An interesting story which arrived at our TV station this morning,
TROPOSHPERIC DUCTING FORECASTS
The troposphere is the lowest portion of the earth's atmosphere, extending
from the earth's surface to approximately 4 to 12 miles above (varying by
location and season). Under certain conditions (discussed below) FM radio
and TV signals in the VHF and UHF frequency bands can propagate over great
distances through the troposphere due to a phenomenon called tropospheric
ducting. A Canadian meteorologist and self-avowed radio/TV "DX"
(long-distance) enthusiast, William R. Hepburn, has developed a method for
predicting tropospheric ducting and provides forecasts (available on the
Internet) using this method, which predict radio and TV signal strength
propagation as a result of the ducting phenomenon.
"William Hepburn's Worldwide Tropospheric Ducting Forecasts" are available
online at www.dxinfocentre.com/tropo.html. The principal content on this
Website is the forecast maps. Six-day preview as well as 42-hour preview (in
6 hour increments) maps for virtually every region of the world are provided
(an example map of Eastern North America is shown here). The purpose of
these maps is to display potential duct paths for VHF, UHF and microwave
signals, indicated by the color shading on the maps using the "Hepburn Tropo
Index" (see scale on the left-hand side of the map). This index indicates
the degree of tropospheric bending forecast to occur over a particular area,
which is an indication of the overall tropospheric radio signal strength on
a linear scale from 0 to 10 (with 10 representing an "extremely intense
opening" for propagation by ducting). Also shown on the maps (indicated by
the letter "U") are predicted "unstable signal areas" where weather
conditions could potentially disrupt signal paths and cause unusual and
sometimes rapid variations in signal strengths.
Mr. Hepburn's Web page also provides some background information on ducting,
indicating that vertical boundaries between different types of air masses
(for example, warm air over cooler air) can refract radio signals. When the
vertical boundary becomes especially sharp, the amount of refraction can
become so severe that signal propagation is extended a great distance as
though caught in a duct, thus the reference to tropospheric ducting.
The raw data for the maps (temperature, humidity & pressure) are extracted
from the Meteorological Service of Canada's global weather model. Mr.
Hepburn has written a proprietary algorithm which approximately mirrors the
atmospheric conditions necessary to produce tropospheric ducting (warm dry
air overriding cool moist air). He developed this algorithm from over 30
years of real-time distant radio & TV observations coupled with 25 years
experience as a meteorologist. Using a freeware meteorological program
called GrADS, the data is ingested, the algorithms are applied, and the maps
are produced.
According to Mr. Hepburn, in the U.S., the Gulf States & Florida are most
susceptible to ducting, especially during the spring months when the sea
temperatures are still relatively low. In the Midwest, Great Lakes &
Northeast, ducting is more common in the fall. Ducting is rare west of the
Rockies except along the Pacific Coast & Hawaii.
The ducting forecast Web page is just one of the sites featured on "William
Hepburn's Radio & TV DX Information Centre" Website (www.dxinfocentre.com),
which also includes information on radionavigation, worldwide broadcast
station lists, and a collection of "TV DX photos" showing screen shots of
distant TV signals (as far as 1,000 miles away) received by Mr. Hepburn in
Grimsby, ON, Canada (located about 50 miles NW of Buffalo, NY).
from the trip as they don't count for awards i'm looking for. However, i
would like it if someone i worked in DM06, DM83, DO30, EM15, EM28, EM45,
EM69, EN16, FN02, FN10, FN30 and/or EN90 would work me at/near home soon,
to reduce the amount of mail sent/received.
By the way, i forget to mention that there were a total of 18 grids worked.
on this trip from 39 different locations, making a total of 192 QSO's.
Cards were generated in both JPEG and PDF formats, so they would be web-
viewable, using homebrew PERL code. So i'm printing these directly from
Firefox (via Acrobat reader). The cards print onto 4x6" card stock and
are trimmed to postcard size, using non-photo blue to mark the cuts.
(If you make your own cards, PLEASE cut them to postcard size!!)
Without some automation, this would clearly be too much work (and not
nearly enough fun).

Hello everyone!
I had a great cruise and due to weather conditions (rain and wind), I wasn't
able to work the birds as much as I would have liked to.... Oh well...
Anyway, I did manage to make a few passes and I have to say that there was a
great turnout on almost all of the passes. Thanks to N2BX for being on ALL
the passes! A familiar voice that I was glad to hear each and every pass. I
will have the grid squares emailed out to all of you sometime this week. If
you contacted me on either A0-27, or A0-51 during the last week, please send
me an email with the details. While I have received quite a few, I know for
a fact that I am missing some of you guys.
I would have kept track of them myself, however my voice recorder took a
crap (Murphys law) and I was only able to write down the ones I could
remember and some partials. Kind of hard standing on the front of a ship
with a HT in one hand, Pocket PC AND GPS in the other and writing at the
same time. All the while fighting the wind! =)
Thanks again for all the contacts!
73,
