Hello Everyone,
> Was on 14.280. Don't remember the day and time.
The current generation of the 20 meter AMSAT net meets on Sunday at 1900 UTC
on 14.282 MHz. Net controls are Keith W5IU and Larry W7LB. Pre-net
activities begin on this frequency at around 1800 UTC before the formal net.

Yes, the 20m Amsat Net is still active Sundays on 14.282. The informal net
starts around 1800z with Keith and Larry as co-net controls. At 1900 Keith
reads the Amsat bulletins with his antenna pointed East from Ft. Worth TX,
and then at 19:30 Larry re-reads them on his Omni in Tuscon, AZ. A short
fill-in session follows, and they close a little after 2000z.
The Net stays on Zulu time, so your local net time will change in a few
months in most areas of the country.
All are welcome,
Greg KO6TH

I remember the hf nets as THE watering hole, water cooler, what have you...
for
AMSAT Oscar news. Yes, copying the elements by hand (it seemed the QRN knew
exactly when to crash, and I hoped to get it all on the repeat from the west
coast net, because
I wasn't licensed to ask for a fill).
When I first discovered Amateur Radio Satellites, personal computers
consisted of the
trs-80, sinclair, and a few others. The Apple II was right out due to price,
and the others were a stretch
to my teenage budget. The Oscar Locator was my computer of choice, and
worked quite well with the
ascending node data. Time marches on...

The EME people do the same sort of Net every weekend (Sat + Sun) on 20
meters...
14.340 at 1600Z. Maybe you guys could fashion it after that format and see
how it goes. Take a listen today...N4PZ is net control but passes it around
to other guys with better coverage in different directions.

Well first attempt at a 40 meter gathering wasnt a complete failer. Talked
to WC7V in MT from Memphis? and K7TRK was weak but there. Im open for
comments and suggestions on starting an HF Amsat group. I think it would be
good for all to be able to discuss things of intrest. Would we need a net
control , open of round table and best utc times and frequency.Who knows we
may be able to get FM operators to be a little more polite.

Hello Graham and Jerry,
A few years ago I compared the 70 cm X-QUAD with a 2 x 19 element TONNA live
on some of the satellites.
They turned out to give the same signal in my non scientific test.

Yes. Newcommers might not realize that you don't need no stinkin computer
to know when satellties are in view. For AO-51 for example, you only need
the peak pass time in the morning and evening for 5 days. These times are
good for the next month or more because they repeat every 5 days. Example:
My "Post-it" note tracker for Maryland for February:
30Jan |31Jan |01Feb |02Feb |03 Feb|
------|------|------|------|------|
11:04 10:25 11:24 10:45 10:00 |
11:40 |
22:16 21:37 22:36 21:57 21:18 |
22:57 |
----------------------------------|
Since the orbital period is about 100 minutes, you KNOW there is a pass 1 hr
adn 40m earlier AND later than the two times per day above. That gets you 6
passes a day. The double times in the last column are because there was no
single peak pass that day, but two equal elevation middle passes.
Since 4 Feb cycles around to the start again, the way I actually write the
above Post-it note for my mobile is as follows. Note the times are the
same, but I changed the dates. I also added the subtraction of about a
minute per day in the overall orbit.
30Jan |05Feb |11Feb |17Feb |23 Feb|
| -5 | -10 | -15 | -20 |
------|------|------|------|------|
11:04 10:25 11:24 10:45 10:00 |
11:40 |
22:16 21:37 22:36 21:57 21:18 |
22:57 |
----------------------------------|
This format increments the 5 day cycle for each column. This chart works
easily for nearly a month without any mental calendar math. Just look at
the column that is the closest date to NOW and then move forward or back 1
or 2 days to the right date. For better accuracy, subtract the minutes
shown for that 5 day cycle.
For 6 Feb for example, start at 05 Feb and count forward 1 day to the center
column. The morning peak pass will be at 11:24 -5 or about 11:19. Notice
how if you keep counting from this 6th around to the 11th, that there is is,
the 11th already labeled for you.
This technique is great for long trips or vacations so that no stinkin
trackin hardware is needed to operate mobile FM satellite, just the
post-it-tracker on the dash board. If you keep track of moving the times
earlier by 5 minues every cycle, it lets you know all passes everyday for
over a month. And you can continue guessing beyond that, because if you are
actually using the satellite, you can update the times as you go.
DETAILS: No, the orbit period is not exactly 100 minutes but more like 99.
But since this is all mental math, then 1 hour and 40 minutes is much easier
to predict. So for the next pass time all you really need to do is ADD 40
minutes and then 1 hour.
For the previous pass it is easier to ADD 20 minutes and subtract 2 hours
than it is to mentally subtract 100 minutes.
Very quickly you get the hang of it.
The mobile operator with OMNI antenna is ususally only going to be optimum
for the high elevation pass anyway, so this really is a neat way to work the
satellies anytime you are in the car. These times are the PEAK elevation
times (CENTER of the pass), so get out there 5 minutes before these times).
You can get the pass time peaks from www.heavens-above.com
My web page gives other examples for some other satellites. GO32 when it
was working for APRS packet, was good for several months because the orbit
did not precess much.
see: http://aprs.org/MobileLEOtracking.html
I wish I had time to write an AUTOMATIC web page calculator for people so
that all they had to do was enter their LAT/LONG and the web page wouild
print a post-it-tracker for you. But I just dont have the time.
It would be a POPULAR site for mobile satllite ops and might actually get
more people on the air! You don't need no stinkin' computer to work
satellite mobile!
There are those who will insist that downloading keps to their smartphone is
a far better technique, but that ONLY works if you pull it out every time
you get in the car and bring up the app and LOOK at it. For me, looking at
the DATE on the post-it note and the TIME printed there is far more likely
to be noticed by me.

Yep ! I remember "Rip" he also was net control on 75/80m net tues nights
also. We used to go there ( late 70's early 80's) to get the keps for all
the birds back then. AO7,AO8,RS 1-11, etc, then a buddy of mine (now SK)
Dick WB1H'IH (his son has his call) Dick and I devised a formula for
calculating the orbits from the keps on a calculator converting 60minute
type values to dec. so calculator would post times correctly, We'd sit down
with calculator and large yellow note pad, and spend few hours, calculating
weeks worth of Birds and their times and passes. Used Mylar over lays back
then to "see" birds. This is akin to "walking to school every day, uphill
both ways in a snowstorm" with no shoes. HI.
73 gud dx to all . CUOTBRDS.
