I would want to take the chance of trying to open those 4 solar panels,

equipment on board, but opening those panels just might trigger something
good to happen. At this point, there really isn't anything to lose. Who
Hi John,
Good trip. I only worked you a couple of times but that's good considering
the time available to me. :) You've made a number of people happy with some
new grids and or new states.

The thing is, running the spacecraft with the panels open only works if the
satellite is fully stabilized so that the panels continually point towards the
sun. Stabilization only works if lots of things, pretty much everything in
fact, is working on the spacecraft. I'd say that we've pretty

I saw a CQ packet from PCSAT show
up on my Mobile on 144.39 yesterday!
Does PCSAT switch between 144.39 and
145.825? I'm reasonably certain I
received a packet with W3ADO-1 a few
days ago...
Yes, in the default mode, PCSAT has the transmitters cross-connected to both
TNC's. SO if

As I mentioned a few weeks ago . . . Not all of us are focused on ARISSat-1.

Hi all in Europe,
It is obviously about time to repeate a few
good points about operating via the FM repeater
satellites.
1. Do not transmit if you can not hear it
2. When the satellite is busy - limit the number of QSO's to ONE
3. Do not call over an ongoing QSO
4. A valid QSO just needs

Hi,
My 232B has worked fine in the past, but just today is acting up (last time
I used it was a few months ago). I can't connect to it with hyperterminal or
HRD.
Following the directions of the manual, I have connected on various bit
rates (1200, 9600), switched the device on, and hit enter a

In my experience, this is often due to a station that can't hear the
downlink, but it's annoying in any case.

Gentlemen,
I have spent a substantial amount on money to set up a satellite station.
During the past tree years I haven't heard too many station in CW!
AO-7 is used in CW but much more DX could be heard if more station were in CW.
On VO-52 we havent enough room. Usually a great number of
I wish we had the same problem on VO52. Not too much activity here in the US
on that wonderful sat, but I have made several CW QSOs on VO52.

Is that not to be expected now that many countries have removed the more code

K3SZH asked you to use more CW several times. I am seconding him.
Please use CW on VO-52 as well.

Nigel A. Gunn,
On tonight's pass at 23:20 I turned the 1268.7/435.15 repeater on. We'll
run this along with the 145.92/435.3 repeater for a few days, except
when collecting telemetry, until we get the rest of the schedule sorted out.

Thank you sharing some good operating practices that would make satellite ops
in the US more enjoyable and equitable as well.

Samudra,
I enjoyed your presentation and comments during the symposium, I
apologize that I did not have a chance to talk one on one. I'll take a
stab at some of your questions
But first a few questions:
Does cubesat employ all open standards, free for use, free of any
copyright -or-
Thank you for your response. I'll do a public search on USPTO.GOV and
see what I can find on the cubesat elements.
Does cubesat employ all open standards, free for use, free of any
copyright -or- patents ?
The answer to this is substantially yes, although especially with patents
it is hard
And lets not forget Steve, N9IP for his enormous effort at video taping the
proceedings.
