Actually, There is another similar WEB page project
That does the same thing for ALL mobile operators,
Not just those with APRS displays. It is simpler
And only has a single TEXT output:
Please see the idea on this web page:
http://www.aprs.org/MobileLEOtracking.html
PROJECT OBJECTIVE: Develop a web page that any amateur radio
operator can go to that will print out this very simple PAPER
tracking device. It is just a piece of paper with 5 columns for
each of 5 days, and on each of those five days, the TIME of the
best overhead pass for that users local area (morning and
evening). For ECHO (AO51) this simple piece of paper with 10
times on it can be used for SHOWING the pass times of ALL
morning and evening passes for the next 2 or 3 months!
You don't need no stinkin computer to always know when AO51 is
overhead while you are mobile! Just look at the TIME on the
paper for today's date. (ECHO's pass times repeat every 5
days)... Each other satellite has similar REPEATABILITY. Just
pring one of these slips of papwer for your favorite satellite,
and you will never need to do a prediciton again, yet, will
always hve what you need in the car to predict each day's pass
times.

Hi folks,
Please is there a schedule like the old AO-13 to understand on which mode is
The AO-7?
Every time I have the Ao-7 on my QTH I cannot hear it and cannot understand
if it is not in mode B
Or I have a problem.
Thanks

consistently hitting the uplink with HTs that tune no finer than 5 kHz will
be a challenge. I learned that last winter when the ISS repeater was active
in Mode B. When I used my FT-817 as a transmit radio and could use the main
tuning dial to infinitely fine-tune the uplink, I had much better - and more
consistent - success hitting the uplink than with my HT, which will only
tune in 5 kHz steps.

Think of it this way. With 5 khz steps you are always within 2.5 khz of
being "on frequency", right?
We operate the V/U FM satellites all the time without tuning the uplink,
and that means we are up to 3 khz off, and everything works fine! So 2.5
khz will be a piece of cake too, plus folks will hear the 2m downlink
much easier.

I spoke to Neil last night on VO52. He said that a storm off Baja was
delaying his departure. I thought he said 3 days, but I may have
misunderstood. He always has a nice strong signal, just no doppler control.

Bob and Dan -
I sympathize with what you're saying and know you both have AMSAT's best
interests at heart. But unfortunately I don't see this exchange going in a
positive direction.
We all know this is not the first time somebody has come on this mailing
list lacking a constructive motive. It appears that, with such a person, it
is a counter-productive to continue the exchange. No matter what meaningful
and accurate comments you might make, it will get twisted or otherwise
re-interpreted in a negative fashion or in the light most favorable to an
ulterior agenda. This is *my opinion* as an AMSAT member and thus *not*
something I will debate online, or in private for that matter. Thus
understand in advance ["Rocky"] why I will ignore any non-constructive
responses to this message.
I think we agree this list is a great thing for those wanting information,
having bona fide questions, or wishing to offer a constructive opinion. I
will be happy to exchange messages with anybody who (in my opinion) is
engaging in something positive or constructive.
I would, however, recommend that those of us who have AMSAT's best interest
at heart try something different to deal with negativism. My suggestion is
to attempt once (and only once) to steer things in a positive or
constructive direction. If that fails, simply state that you are not
obligated to exchange messages with anybody you believe is not pursing a
positive or constructive agenda. Make it incumbent on the person making the
objectionable comments to put things back in a positive direction if they
wish to get any replies.
If everybody who has AMSAT's best interests at heart followed that, I think
we'd have much better exchanges on this list. Just a thought...
73, Ken N2WWD

Hi John,
Yes it was a busy weekend and yes it was I, KL7XJ operating as KL5O
special event station. I was
the only Satellite op from Alaska. We had numerous HF stations on state
wide. This our states 50th statehood
anniversary year. I was contacted shortly before and asked to do the
satellite ops. Did not have much time
to get a message out to let folks know about the event. The dates were
selected as the anniversary
when the US purchased Alaska from Russia for 2 cents an acre.
I want to thank all the stations that participated. I know there were
others that were trying to get the
contact. Again I apologize for not getting more info out in time..
The www.KL5O.com website will
have the QSL info. My logs have been submitted.
73,
Dale - KL7XJ

Just so that there's no confusion, the TH-F6a is *not* a true full-

Hi Drew,
My "work-around" (unless someone comes out with a finer-tuning HT between
now and then!) is simple. I'm going to use a combination of the 5 kHz and
12.5 kHz tuning steps on my HT to program a set of memories that "Doppller
tunes" the uplink in 2.5 kHz steps. That way, I'll be able to stay fairly
close to the uplink throughout the pass. I'm confident the "one true rule"
will still apply regardless of the receiver design. It has on AO-7 and VO-52
when I've worked passes using AFSK through an HT to send CW on those Mode B
satellites.
I'll use the same downlink in each memory because I've done just the
opposite with our Mode J satellites - that is, use the same VHF uplink all
the time and only Doppler-tune the downlink.
Please don't mistake my comments as any kind of criticism; they aren't
intended that way at all. I'm looking forward to the challenge, and just
hope others understand that one true rule and its impact on Mode B operations.
73 to all,
Tim - N3TL

All,
Many thanks for those replies off the list.
Yes, just like Tim said, I am looking for HTs that are currently in
production. I am trying to get local high school club station to work
via the satellites. A true full-duplex HT can make this process easily
accepted by the students. At the same time, the school will always
require new HT purchase from the market.
It's sad that I can't find a good choice. DJ-G7 does not seem to be
good enough.
I believe there will be a boost of satellite operation in China with
the launch of XW-1.

I just check the AO-7 log to see what mode is being reported by recent
contacts:
http://www.planetemily.com/ao7/ao7log.php
My understanding is that when AO-7 goes into eclipse, it shuts down and then
when it comes back into sunlight, it re-boots and randomly selects a mode.
Right now while it is always in sunlight, there is a 24 hour timer that
toggles between modes A and B.

Hi folks,
Please is there a schedule like the old AO-13 to understand on which mode is
The AO-7?
Every time I have the Ao-7 on my QTH I cannot hear it and cannot understand
if it is not in mode B
Or I have a problem.

I would go with what you heard about departure date...I got my report from
someone else and I'm not even sure they spoke directly with Neil

I spoke to Neil last night on VO52. He said that a storm off Baja was
delaying his departure. I thought he said 3 days, but I may have
misunderstood. He always has a nice strong signal, just no doppler control.

I have not spoken to Neil (W6FOG) but I have heard that he has postponed his
departure due to the hurricane activity coming into Mexico from the Pacific.
What I've heard is that he is now planning to depart on 11/4 but I have not
spoken directly with Neil.

Vincenzo,
Here is the link to the AO-7 Log page, which should prove very helpful:
http://www.planetemily.com/ao7/ao7log.php?PHPSESSID=71f968d1c9db80c36565267171
ae025b
On it, you should notice that the "toggle" between Mode A and Mode B seems
to occur sometime between 0400 UTC and 0600 UTC daily. I use 0600 UTC as my
personal guide.
Based on the way that toggle has been occurring, the following rule of thumb
should continue to apply until the Grand Old Girl decides to do something
else on her own .... hihi.
Using the calendar as a guide:
October 2009 - She will switch to Mode A between 0400 UTC and 0600 UTC on
odd-numbered days Ie.g., Oct.21, 23, 25, etc.). She will switch to Mode B
between 0400 UTC and 0600 UTC on even-number days (Oct. 22, 24, 26, etc.).
November and December 2009 - She will switch to Mode A between 0400 UTC and
0600 UTC on EVEN-numbered days (Nov. AND Dec. 2,4,6,etc.). She will switch
to Mode B between 0400 UTC and 0600 UTC on ODD-numbered days (Nov. and Dec.
1.3.5, etc.).
Please note that for quite some time earlier this year, she remained in Mode
B without a mode switch. Use the AO-7 Log Web page to confirm her mode
whenever you are planning to operate.
I hope this is helpful.
73 to all,
Tim - N3TL
