Greetings from Kuala Lumpur, Malaysia.
I have built one LVB Tracker complete kit from AMSAT-UK, and am
extremely pleased with it. Now I would like to build another unit, but
this time from scratch. I have two questions about this tracker,
which I hope someone can help me clarify.
1. Can someone kindly advice a suitable LCD panel for this tracker?
Would the Powertip PC1602ARU-HWB-G be compatible with this tracker?
(RS Part Number 466-6452)
2. I am also very interested into the Ethernet interface, but have no
clue on how this works. I know a suitable unit is produced by
Lantronix but that is about it. Could someone kindly advice what do I
need to get the Ethernet interface going? Is there an evaluation kit
readily available like the one from FTDI for the USB interface?
Any help and advice is really appreciated. Thank you very much in advance.
Sion Chow Q. C.,
I was wondering if anybody has experimented with the FLEXI RADIO Software Defined Radios on satellites. I know the
SDR 5000 can do dual receive, but can cross-band full duplex be done as well?
Grateful for any wisdom.

Good Afternoon, Everyone.
Last month, a question was posed about the possibility of reconfiguring
LUSAT/Oscar 19 in the "bent pipe" style that AO-16 is currently in. As I am
writing this, both AO-16 and LU-19 are overhead...and both have stellar
Is there any news/update as to whether or not this can be accomplished??
Upon reading the Satellite Handbook, it appears as though 16, 17, 18, and 19
were pretty much similar. If I am wrong, then I will stand as corrected,
but if 16 could be converted in such a fashion, what prevents 19?
Wishing for Spring!

WELCOME, Kent, to this wonderful aspect of amateur radio!
Because you did hear something earlier this week, tha means you're
close to perfecting your setup.
Check the ideas on my tutorial at...
...and see if any of that helps.

Weird stuff today, I even checked my antenna to make sure it was up ,
frequency correct, but not nearing either PCSat or ISS today and last 2
passes were directly overhead.

Welcome to the sats. I just started myself a few
weeks ago. AO-51 is quite popular and there are
usually many stations calling when it is on mode V/U
(Friday through Monday UTC). So if you are not
hearing anything, even on a high pass, there must be
some problem with your receiver/antenna, or you are
not tuned to the correct frequency, or your tracking
program is off and you are not listening at the
correct time, etc. There's a nice AO-51 operating
The other sats you can work with FM-only gear are
AO-27 (daytime only) SO-50 (a bit weaker than 51 and
27), and the International Space Station (although
transponder is often turned off).

>>>Hello all, my name is Kent Frazier, K5KNT. I am
just getting interested in
working amateur satellites. I just joined AMSAT on
Tuesday, 26 February
2008. My current hardware is an Icom IC2720 dual band
in my personal vehicle
with a Comet C767 dual band antenna. I also have an
Icom IC-T22A 2-meter
hand held with a Diamond RH77CA antenna.
I've been trying to listen to passes of AO-51 over the
Unfortunately, I haven't been able to hear anything
since Monday, 25
February at approx 01:04 UTC (Saturday 24 FEB 19:04
CST). At that time, I
thought I heard the call W9CPV.
I'm currently using Satscape as my tracking software.
My Gridsquare location
Are there other satellites I could monitor with the
above equipment? Any
suggestions for making my first contact?

The Greater Houston Hamfest is Saturday, March 1. We will be on the
satellites. Look for our demo station on the morning passes (especially
AO-51 at 9am CST).

Uh, no you didn't.
You simply keyed up and announced you were listening.
How about trying to use the more preferred protocol of...
