Hi Art,

Wow!  Thanks!

You would also need a dummy load and narrow band signal
source with your IC-7000.  I have two ideas for the signal
source if you have time (or another volunteer's time or
someone of your own delegation) to work on an audio
interface cable.  . . .

1. Someone's laptop PC (or MacBook or iPhone/Android/device)
that plays a 700 Hz sine wave mp3 ad nauseum, although boring,
would be nicely functional for us.  A very important
contribution indeed!

Or the same cinfiguration, but a recorded voice MP3, with the
actual content of little concern -- but something from the
Houston AMSAT Net archives might be a nice touch.  Or Newsline
or the ARRL Audio News Service, etc.  If your interface radio
cable is made with a standard (3.5mm TRS, not TRRS) stereo
audio connector on the source end, then we can plug in any of
a number of devices that I/we will have on hand.

2. In addition to the above source, I can loan you an old
(never been flown) Radio Shack "parrot" repeater module
that is slated for a future high-altitude balloon payload.
This is a small, battery-operated electronics box with
everything but a transceiver in Crossband mode.  With the
proper audio and PTT interface cables made for your IC-7000,
these can "simulate" a bent pipe satellite, less the Doppler
shift.  However, things could get a bit messy (RF-wise) in our
venue, but, after, say, 3:00 P.M., . . . who would care?

If any of the above becomes "too much" for you then let us
know on the amsat-dc list and we will try to get you some
relief as needed.


About the students from Thomas Jefferson HS, they are
welcome to join us.  But I might caution to bring more
adult Elmers with you.  Please also have each of the
students and Elmers contact Martha to register in advance
as noted at:


and ANS and amsat.org and several other sources.

THANK YOU for getting the word out.

THANK YOU for supporting us another year with your great
photography skills!

Hi, Pat!!

Will bring camera.  Will also try to persuade some TJ students to come along.

If you'll need a strong 430 MHz source, I've got an IC-7000, which is multimode.  The power level can be dialed pretty low.

Anything else I can do?

Dear fellow AMSAT members,

Please go to http://patkilroy.com/amsat-dc/
and read everything top to bottom.

Then please let me know if you have any
comments, questions, recommended edits or
anything else before I send it off to be
published in this weekend's ANS bulletins.

This is our workshop.  Only a couple weekends
away.  I hope you can attend.


1. We are looking for someone to bring a UHF
signal source for test purposes for the day,
something more substantial than an FM handheld
transceiver if possible.  A simple analog SSB
transmitter in very low power mode looping a
recorded voice message would work, and be pretty
cool too. Takers, any one? Please contact me.


3. We still need volunteers for this event.  The
task list is quite similar to those of our previous
seminars and workshops (see Archives).  This event
is run by volunteers for volunteers.  For example,
two AMSAT greeters are needed.  Also, a video person
with lights, a video editor person, a food organizer,
a Net Control Station for talk-in, go-fers, clean up
crew for examples.  (I believe Art Feller is going to
bring his nice big dSLR still camera and gear, so we
are covered for publish-ready type still photos.)

4. We need to get the word out.  Can you pass the
word and the amsat-dc Web page URL to your club news-
letter or on a Net?  Talk it up on your repeater?
Tell a college kid?  (YES!)

Who knows how to get an event announced on Newsline?
On the MDC section Web page and newsletter?  Please do!

5. Have you registered through Martha yet?  (Please
call her even if you only "might" make it: Unlike
local hamfests where you can walk right in, THERE
WILL BE NO registration on the day of the event!)

THANK YOU for your support.

We will have a great time!
