Great stuff, Mark. I'm an old, dusty assembler, and later a C programmer.

Hello AMSATs,
I agree that APRS can have a higher power transmittter, because of its small
amount of time to get the data broadcasted. However the workability with the HT
and whipe antenna is only an advantage for the downlink. For the uplink there
will be no advantage.
Personally I believe

This is probably the most important email about FO-29. I've high lighted and
underlined the most important parts of the message. I looks like FO-29 will not
be in full operation until the first part of 2010. At this moment it is only
commanded on over Japan as noted in the schedule. With the is

I had to go on some unexpected travel out of BWI the past couple of weeks.
So I did some reconnaissance and developed a couple of maps that depict

Awesome stuff!! I'll have to check out this library tonight. I started
hacking at something similar but started digging into the internals of
SGP4/SDP4, then got distracted and never finished. If you have a rotator,
it'd be a cool quick project to slap pyserial on there and control your
rotator.
Mark,
Thanks for the link - I've been considering trying to cobble together
a "web service" that will create an ical or rss feed of upcoming
passes over my QTH. Hopefully this library is the kick in the rear
end I need to get working on this.
Thanks,

FDMDV uses a 1400 bps codec, occupies only 1100 Hz and operates with any SSB
transceiver. Comunications doesn't have to be full duplex. At 12-16 kbps the
satellite and ground stations could alternate with short bursts of voice or
text. This wouldn't fit in a 2.4 kHz SSB bandwidth but would requi

I have not had this problem but have heard you mention it before. I did

I posted the following on this a week or so ago:
Spacetrack is predicting that CUTE 1.7 will decay on 10th October.
My predix software predicts that the first time the satellite hits terra firma
will be 19th December.
What do others think?

Hey Mark--
We also use pyephem for web-based pass times calculations at Cal Poly.

Hi All,
The house I just bought precludes me from even using my arrow inside as
there must be something un-RF friendly in the walls. Therefore, I was
looking for a roof antenna and the October QST article on the QFH inspired
me to build one. However, after doing some research, I have come up with

Their mass differences are showing up quite clearly in the Mean Motion.

Uhmmm not APRS .. I mean like RTTY or PSK31 ??
I guess you would have to try that on a linear bird ..
But I am guessing that the doppler would be a major problem?

Looks very nice, all quality parts, and the shipping was quite fast,
considering it came from India.

Hey all,
I will be working every possible pass of ao27, so5o, and ao-51 starting noonish
friday oct 2 pacific time. We will end mid day on sunday.
This and DM08 may be valuable to some. I will sql each call that needs one.
Have a great weekend
