John,
Very good explanation and after that I played with it a bit more last night and
got it working almost fine
as you can attest when we had a QSO on VO-52. So I stand corrected, and will
from now on use full
doppler computer control whenever possible :).

Seems to me that every program that I have tried I had to
fine tune it just a bit. But once that sweet spot was found
never had to touch it again.

Hello,
Nasa TV Schedule reports:
*August 3, Wednesday
10 a.m. - ISS Expedition 28 Russian Spacewalk Coverage (spacewalk
begins 10:30 a.m. EDT.)*
it seems that the deployment of ARISSat/KEDR will be one of the first
tasks of the EVA, does anybody know where to find the EVA timeline?

Hello John,
I totaly agree with you. I work with full doppler control (rx and tx)
from the moment that I started on the birds.
That way I can concentrate more on seeking new stations and logging them.

Hi Alan!
I wanted to make a couple of points regarding some of your comments
from your earlier post...
There was an article in the Journal a few issues back on why the various
manual techniques are only approximations, sometimes surprisingly bad ones.
I think the author's call was WA4SCA.
One of the things I like most about MacDoppler is that I can turn the VFO and
it will follow me. It does not enforce that I use the program to change
frequencies. That allows one to use a simple VFO know interface to change
frequencies while still having full Doppler correction.
I have tried
When I bought my TS2000 several years ago I too played chase the downlink for
about a week and did a fair job. But if it was annoying to me to have to do
that, I knew how annoying it must have been to other, Doppler controlled
stations chasing me. I am not a computer whiz by any means, but my

OK - Charging of the ARISSat-1's battery is scheduled for July 27. And a test
this weekend.
Will the battery be charged a second time - before EVA-29 on August 3?
What is the expected/anticipated battery charge state to be after the July 30
test? Good enough for deployment without another
Curious..
If Gordon (always ready with a cheerful comment) is accurate, then what is
the purpose of the BBS? Also, Kevin is far from 'selfish'...he is just using
the available resources. Helpful education is far more useful than lame name
calling, Gordon.

This doesn't make any sense to me. It looks like a launch, not a
descent.

Hi Clint,
The battery can run ARISSat-1 for about 6 days on
the ISS so it will still be almost fully charged
if they run it for just 1 day.
Once it is deployed, the solar panels will charge
the battery.

None practically. It is the most inefficient AX.25 packet arrangement
possible.
AX.25 connected packet depends on line-by-line ACKS. This works on a
two-way balanced link when both stations hear each other reliably and

Hi Everyone,
This weekend I was able to sneak in some satellite operating during a
