Hi Samudra,

Good to hear from you!

1. Again, I am narrowing down to one LARGE room,
with 6-ft tables, chairs and outlets not too far
away.  And plenty of elbow room for safety, room
for antenna elements to spare our eyes!  Audio
noise level will be high at times, other times
for a speaker, hopefully low.  Hopefully a house
PA system will be in place, otherwise I will
import my own sound gear to serve as a PA.

2. Well, there will be a Powerpoint projector,
with signal cable for one laptop at a time.

3. The plan is yes, for access of the NASA
Guest-CNE WiFi network available with fairly good
coverage in all buildings on site.

I envision in its most basic form, one or more
RF sources (433.920 MHz AM/FM/USB to start) will
be alive during the entire event.  Folks will
come in to set up their PORTABLE station and get
it showing satellite positions in common (that
is, the correct answer) and then receiving the
RF sources on their SDR receiver or conventional
receiver/transceiver.  I would like to see all
stations capable of copying USB on 2m and 70cm,
but some might not have any but FM, a pity.  ;-)

Some will need more help than others.  That's
okay.  We are all there to help each other.

With a "donation" average of, say, $20 per AMSAT
member, I believe we will be able to afford some
catered food and no one will need to leave the
building for lunch.

I have no clue how big or how small of an event
this will be.  A lemon that will be made into
lemonade will be the fact that advanced
registration for each individual will be
required by a certain date.  February 15 for a
non-US citizen, and TBD (a week or ten days) for
a US citizen.

How copy?

Did I answer your questions okay?

Pat, just a question, in a common room, what is the noise level there? will we need any sort of intercom/talkback system to coordinate trainer/group/exercise?

Or, also, how about a remote screen sharing program for accessing a projector - to allow instructors to show teams on what to do? (unless there will be a projector)

Last question, will we be able to use our laptops to get internet access there using the GSFC  guest wi-fi network?

Hi Bruce,

Thank you for your great comments and ideas!

First, yes, please check with MARC to see what
conditions they would like to set for sponsorship.
A $20 across the board fee for AMSAT members
sounds okay.  With a followup to the discounts
if possible.  (Would be nice if we don't have to
deal out money during the event.)

Please check to see if the wildapricot system
can "refund" half of the fee after the event for
where it is confirmed that a person indeed (1)
brought a "substantial" demo station or (2)
gave a "substantial" presentation knowing that
individuals will be offering extemporaneous
short talks/guidance throughout the event, or
(3) that the attendee is an AMSAT-NA Life

I really like the idea of offering Life members
the discount, even though *I* do not qualify

So, maybe (gulp!) it should be $30 for non-members,
hoping that those individuals will call Martha
to become a member and effectively get "$10 off"
in a way??

To recap: $30 non-members; $20 AMSAT-NA members
and sponsor/MARC members (claim one, unfortunately
not both); $10 AMSAT-NA Life Members, right off
the top.  And we consider to apply any discounts
*after* to those who wish to claim a discount.


(I expect to pay full AMSAT $20 price -- to test
the system? -- and probably won't bother to claim
a discount.)

"Leftover" money can be used to buy more goodies/
food/misc/other for the event itself and then
and only then any further "left-over" be donated
to AMSAT-NA.  Drinks all day and a catered
lunch is sounding better all the time.

I will drop the idea of a raffle or a silent
auction SOON unless we find someone to delegate
the task after the more important roles are
filled.  Since I just might consider doing this
SAME workshop annually then some things like
this might wait a year before implementation.

Yes, there is a dual-use factor between the
high-altitude balloon portable ground station
and the amateur satellite portable ground station.
In fact, one of my RF sources is to be one of
the PICetSat modules beeping on 433.920 MHz AM/

I am working on getting a LARGE room with 6-ft
tables and chairs available with lots of elbow
room.  Not the same building as before, it is
under renovation.

A live demo is good but depending on which
building we are in, and the complexity of who's
station employed, will dictate.

I'd hate to hold a concurrent flea market and
have to answer to that with my employer, but
there HAS to be a low-impact means to barter

SDR yes!  Maybe Tom Clark will show his little
toys and provide color commentary???

Things are starting to gell.  Let's keep the
idea exchanges alive.  More comments?

Pat, Dan, Steve .. and all

Pat - thanks for getting the ball rolling on this --

1. Great!

2. Our Club (Montgomery Amateur Radio Club - MARC) has recently purchased a
subscription to a Membership Registration Service - to manage the club
membership -- One of the functions it offers is  event registration
(http://www.wildapricot.com/event-registration)   I have initiated an
inquiry with our board to see if MARC is willing to be a "sponsor" of the
AMSAT-DC workshop -- and allow us to use the event registration feature of
this SaaS (Software as a Service) offering.  Notice it would handle the fee
collection, and if needed, a structured fee plan.

3. I am in favor of a basic fee -- $20 seems reasonable.  Yes, I could see
waiving some or all of it for presenters / demonstrators.
I agree to stay "on site" for lunch would be more efficient.

  Option D:   -- let's see how many "helpers" we get to see if we a silent
auction is an option.   I am assuming we would have to have some contingency
plan if some items don't get "bought" at their minimum price.

4. people are probably going to block the whole day -- so we could probably
run until 4:30 --   Maybe have all the "formal" activities wrap up by 3:30 -
Do we need to allow for some cleanup time -- to get the donated space "back
in order"

-- it would definitely be good to get rolling by 10:00am --  are we thinking
lunch @ 12:30 - 1:00 -- maybe we should start a little earlier?

-- I think it would be nice to have a couple of 20-30 minute talks or
talk/demonstration planned. --
Would we be meeting in the same room as last time -- could it be partitioned
off -- so that if someone did not want to attend a "talk" they could keep
browsing?  --

5. Do we have the option of opening it up for "satellite related" equipment
swap"  if hams want to bring in some equipment they want to sell?

6. Other Ideas --
   -- Obviously SDR's is one of the hot tech topics --   I went ahead and
got one of the $20  SDR dongles (January QST)  and got the SDR# software up
& running --
  -- I'm still not completely sure what the I & Q signals are -- how are
they created --
It would be great to have a SDR SME there to answer questions.

Regarding "working the birds" -- I think one of the biggest challenges  -
Especially with the linear birds is managing the Doppler shift ...
  -- how are you doing it on your portable station?
It would be interesting to have some sort Doppler shift simulator  and let
participants get a sense of the tuning required.

7.   Are you thinking about working a pass during the workshop?
   FO-29 goes overhead between  11:30am - 12:30
  We should also be able to get in an SO-50 (FM bird) pass

8.Possible Talk Topics
    -  "getting ready to work the next AMSAT-NA cubsat
    - SDR's how they work
    - AMSAT-NA - Current Operational Status of existing sats
      -- Near future plans - (can we get Drew to stop by?)
    - Pat - do you have any of your balloon hardware you want to show off --
or talk about recent flights?
