Hi Alan,
First of all I'd like to thank you and all those involved in the XW-1
project, so far it appears to have been very successful indeed.
Would it be possible when publishing schedules that you do it in a
similar format to that Jan-Albert uses for SO-67 ?
i.e. include the continent being covered. - I'm sure everyone would
find this helpful.
Example:
> Sat 19 Dec 2009
> 00:06...Japan
> 00:24...Australia
> 01:43...Asia
> 07:56...Europe
I don't wish to sound ungreatful for your hard work, just pointing out
how much easier it would be for everyone. If for some reason this
isn't possible, then I (and im sure others) won't be offended.
Thanks once again
73

Hi, Pete --
I, too, prefer the format you propose. However, I note that the SO-67
team found that they didn't have the time to do that for us this time.
I imagine these commissioning groups are very busy. However, in the
case of SO-67, something great happened: Luc just stepped in and
converted these raw hours to locations for us on that thread.
So I'd propose that we distribute the workload a bit and a) request of
the satellite groups only hours and days; b) have one or more of us
here on the list convert these to lists of hours, days and locations.
It would be great if someone volunteered to do this every time, but I
wonder if it might be better to just allow whoever has SatPC32 (or
whatever) up and running to do this if it isn't yet done.
73, Bruce

I am reading many comments on the XW-1
I ask this satellite this working 2mtrs 70cmt FM.
I can work only satellites in FM. I don't have equipament for SSB.
Thank you in advance.
Happy new year .73

Hi Elan, WB2IOL
Actually 50 feet of LMR400 adds 0.75 dB to the Noise Figure of your
144 MHz preamplifier and 1.35 dB to the Noise Figure of your 432 MHz
preamplifier.
Why deteriorate the Noise Figure of your receiving system adding the
losses of a coax cable between the antenna and preamplifier ?

Hi,
Actually, this is the only antenna and setup I can affort and I very
satisfied with. But it should be combined with V & U preamps at the
nearest place of both antenna. They are working great and they will be
a good setup even if I install a more serious setup in a near futur.
Using a good feed line is essential... I'm using heliax LDF4 with N
connector.

Hi, it is more efficient to keep preamps to the nearest place of
antenna..... at this moment you are also amplify noise that is pick up
by your coax. I tested the difference before changing my feed line
with heliax ldf4, and you can hear a difference on low elevevation
pass. I really think it worth it, even if you have only 50 feet run. I
have alsmost the same lenght of feed line at my place.
