Re: Winning practices for the Easy Sats, (no whiners)

Hello Mike.

Here, there are two operators who get answered:  Those who call someone
specifically, and those who announce their presence (we do have quiet moments
here, so sometimes this is a good idea).

i.e. be brief, callsign and signal report only, if things are busy, maybe
name/location/grid, if it's quiet.

Agreed.  Long CQ calls merely waste transponder time (and there's only 15
minutes or less of that per pass, use it wisely! :-)

The Internet is an excellent medium to promote unusual satellite activity.  My
own site (which is geared mainly towards the FM birds) started out as a way of
promoting my operation from public transport.

Hehe, been there (have you been reading my site? :-)  ).  Maybe I should
approach the news services that read the story for permission to publish
excerpts :-)

If you can.  I have found that skillful antenna orientation can help as well. I
am yet to build my gain antenna, and yet get my fair share of contacts on the
FM birds. :-)

Indeed.  In my case, I have no feedline losses and fairly sensitive Rxs :)

Yes, they do, and those who don't play the game get branded as a "bad

Yes, I like to wait 3-4 seconds if there is no response from the intended
recipient of the call.

One point I will make is that if you run minimal gear like me, you have to be
very attentive to propagation conditions and listen AT ALL TIMES.  By this, I

1.  When listening to other stations, take note of the downlink strength and
re-orient your receiving antenna if the downlink is too weak.  On UO-14, this
could take constant adjustment!

2.  When calling and in QSO, keep listening (this can be a learned art, but it
can mean the difference between success and failure), and if your uplink seems
a little weak, quickly re-orient your transmitting antenna (this is where
separate Tx and Rx have a big advantage) while talking.

3.  This ability to listen and talk at the same time is also useful in pileups.
High powered stations will notice people as they dive for the PTT and be able
to back off, QRP stations will know if they've been trampled and save battery

The old saying fits well here.  If you can't hear them, you can't work them.

As someone who has worked 99% QRP ( < 5 watts EIRP ) into the FM birds, I have
to agree that skill, persistance and a bit of blind luck will enable many
satisfying satellite QSOs.  Last weekend, for the first time, I had access to
high powered satellite gear (for the public demo) and was able to put in the
best ever signal, but the QSOs I find most satisfying are the train and tram
mobile QSOs from last year , and the recent QSOs via UO-14, which is a somewhat
more challenging bird for those without gain antennas to work.

My satellite station is this:

For SO-35.

70cm uplink - Icom IC-T81A (3.5W measured) with 1/2 wave whip.
2m Downlink - Standard C-58 (in FM mode!) with 5/8 telescopic whip.

For UO-14
2m uplink - Alinco DJ-500T (1.8W measured) with 5/8 telescopic whip.
70cm downlink - Icom IC-T81A with 1/2 wave whip.

I do use headphones which belong to my walkman, and provide excellent downlink
audio.  The Alinco doesn't get used on SO-35 because it's busy recording the
audio in the shack during the pass (this may change when I get the FM92
programmed for the satellite band).

With this gear, I've had numerous contacte all across Australia, New Zealand
and Papua New Guinea.
