Hi All,

this mode. It's time to get some transmit time on those L-band

Kent,
I think this is an excellent idea. Perhaps something to generate an
ical file for sat modes on the birds that change modes often (think
AO-51). I would also be interested in helping with the development of
this system.
Joe,
I would be very interested in a script that consumed this RSS feed and
updated the predict.db file. Maybe even a patch to predict that made
this a built in feature?
Thanks,
Josh Smith

A patch to Predict itself would be a project for a better C hacker than
myself, but an external script would be pretty easy, as long as the feed has
the necessary data (name, NORAD number, freqs/bandwidth and keps) in a
convenient format. If/when the feed goes up, I will write something and post
it here for anyone interested.

You could, of course, include some additional "human-readable" info that the

Joe,
This Should be cake, although i'm not familiar at all with the predict
source code. I should be able to hack this together in my spare time.
In fact, i'm going to set up a new VM tonight just for satellite app
hacking and such.

Josh,
Cool. Let's see what type of feedback we get on this.
I'm not familiar with the predict.db file. Where does it originate and
what system uses it? Send me a sample copy and I should be able to hack
this together reasonably quickly, once the RSS tags are well defined.
For the time being, you're welcome to browse through my scraping
script. This is what I wrote to pull the status data off the amsat
website and push it out to a txt file. It's fairly rough code but it
works :-)

I second those comments, Mark. I have ARR mastmount 160 watt preamps for 2
and 440. Huge diff.
I was not surprised that it made a diff on the linear birds. What DID
surprise me is HOW MUCH it helped with low passes on the FM birds so that I
could work longer distances. What I discovered is that others were hearing
me, but I did not hear them until I got the preamp (before the preamp I
would call CQ satellite and not hear a response, but I would get an email
from the op saying he was calling me. After the preamp, solid copy!)

Hi Jerry,
I cannot say enough good things about the preamps AND the PEOPLE at Advance
Receiver Research! They are always personable, quick to ship/repair, and
their products are awesome.
I have around 5 of their preamps around the shack right now (okay, four are
at the antennas where they belong!). It makes the difference between
hearing and not hearing.
In the last few weeks I finally added a 2M mast-mount model at the antenna.
I keep kicking myself for not doing it years ago...I can't believe how much
better I can hear AO-7 now.
Suggestion---I have found that over the years I tend to "mess around" rather
than get what I really want to begin with. In that vein---I don't think you
will never regret getting the 160 Watt mast mounted versions:
http://www.advancedreceiver.com/page10.html
Models relevant to 2M and 70 cm:
MSP144VDG-160
MSP432VDG-160
Yes, they are an investment of hard earned ca$h. But they're a GREAT
investment, if you want to hear...

Erich,
Wow, thank you so much for the reply. This is wonderful news. I was pulling
my hair our trying to figure out an easy way to do the hardware mod, and like
an angel you give me a much easier solution. The patch works fine and I am in
business.
One question: In the last line of the patch description on your website, it
says: "To correct the downlink frequency during a QSO use the "Downl. Corr."
controls in menu CAT or the +/- keys of the numerical pad of the keyboard." I
thought that the software automatically corrected the downlink frequency?
Does this mean we should use the "Downl. Corr." controls or the +/- keys and
not the VFO dial on the radio to QSY?

A most interesting (learning) QSO was completed with Greg KO6TH on AO-51. L
band antenna (22el yagi) mounted inside a 20M Quad, no elevation ability.
70cm yagi on a az/el system-none of it computer controlled. Tx a IC-1271A
driving a KJ6KO amp. No automatic doppler correction. With three rotors and
manual doppler correction and trying to see the computer screen too far away
for my bifocals to work, it was a learning experience. I will be calling
Martha tomorrow to order the LVB tracker, and putting one of my 16 turn helix
antennas on the az/el system and move computer display or get stronger
glasses! This is fun stuff! Thanks to Drew and the crew for playing with
these different modes. I can receive 2.4ghz with a 3 foot dish, but I ran out
of hands.
try it you'll like it!

Hi All,
I had AO-51 all to myself right after the mode change. It sounds great in
this mode. It's time to get some transmit time on those L-band
modules/upconverters and/or check out your S-band downconverters!
By the way---many of us use 1268.703 on the uplink!!
April 13 - April 19
FM Repeater, L/US
Uplink: 1268.700 Mhz FM
Downlinks: 435.300 and 2401.200 Mhz FM
Hope to work you there.
73,
Mark L. Hammond [N8MH]

Yes, there have been Yuri's Night parties many places.
It's also the 28th aniversary of the STS-1 launch.

Hi Bill,
my remark in the last line of the patch description relates to satellite
operation with a single semi duplex radio, i.e. the IC-706MKIIG.
Of course, the software automatically corrects the uplink and downlink
frequencies for Doppler correction and for QSY around the passband of SSB
sats you can use the radio's VFO knob also with these radios.
The remark refers only to manual frequency "corrections" with SSB sats. With
satellite radios, i.e. the IC-910H, you can fine tune your uplink frequency
with the "Upl.Calibr." controls or the +/- keys for best audio pitch of your
own signal and save the correction in Doppler.SQF for future program starts.
That doesn't work with semi duplex radios, however, since you can't hear
your downlink signal. But you can assume that a QSO partner will tune his
radio for best audio pitch of your signal. That will possibly change also
his uplink frequency. Then you should leave your uplink frequency unchanged
and correct your downlink frequency for best audio of his signal via the
"Downl. Corr." controls or the +/- keys. That's the reason why the +/- keys
with satellite radios correct the uplink frequency but with semi duplex
radios correct the downlink freqency.
Recently I had several SSB QSOs via FO-29 and VO-52 with a single
IC-706MKIIG. That worked very well.
