I feel your pain Scotty, I have a similar problem with my 9100, LVB, and
SatPC32. In my case the LVB would show a memory error and I would lose
calibration. Only way to fix would be a full re-calibration. This is a real
pain to go through during a pass so I just remember to turn on the LVB, then
the 9100, then bring up SatPC32. I know of no other way around this....

Hi, I fired up my SatPC32 in the wrong order from the way I usually do it,
I usually turn on radio and my LVB tracker first then fire up the computer.
The LVB works fine,but I got a message ?could not open Com3 and to check if
It was available? this is weird as this laptop is dedicated only for
satellite use, and I have not changed anything. I use a Kenwwod IF232r
between my computer and my TS790a radio. I opened the device manager and it
says for the FT232r USB UART ?the drivers for this device are not installed
(Code 28). I tried to downoard the driver from ZLP and it still does not
work?, any ideas? Tnx in advance. 73 de VE6ITV Scott

Yes, Pavel, but since the frequency heard by the satellite as it
approaches is higher than what you sent, you need to send at a lower
frequency to compensate. The idea is that you want the frequency heard
at the satellite to be constant.
As the satellite passes the midpoint, and recedes from view, the
frequency it hears is lower than what you transmitted. So you need to
send at a higher frequency to compensate, again so that the satellite
hears a constant signal.
So, during the pass your transmitter needs to go from lower to higher.
The physics works the same for your reception (it better!), but since
the satellite isn't changing its frequency to be constant at your end,
you need to move from higher (on approach) to lower (towards LOS) to
conpensate.

Colonel Fred Kennedy, USAF, Space Production Division and Program Manager
for the Wide Field of View satellite (hereinafter WFOV) has accepted the
proposal to allow Virginia Tech to place a hosted payload consisting of a
Software Defined Radio designed and built by Rincon Research Corporation
using support equipment and antennas designed by Virginia Tech and other
volunteers to this effort. The spacecraft hosted amateur payload will be
included in the Aquila M8 bus by Millennium Space Systems who is the
integrator for WFOV. Our first role and immediate action item is to raise
the $100,000 for Millennium to complete the study of the inclusion of this
payload on Wide Field Of View. Following successful completion of this
study, Virginia Tech will raise money to defray the cost of integration
and launch of this payload. After achieving orbit, volunteers managed by
Sonya Rowe and Zach Leffke of Virginia Tech will operate the payload for as
long as it is over the US. We at VT with the help of the ARRL will
prepare partners in other regions to operate the spacecraft should it be
moved in order to allow the WFOV to accomplish its primary mission and be
prepared to take over operation of the hosted payload on its return to the
area of CONUS.
Colonel Kennedy told me how much he admires how unbelievably capable
amateurs around the world have been in their many organizations to get
spacecraft to orbit and wishes us the best of luck in the onerous task we
will have of raising $5M to get this on board.
I will be making many details public now that Colonel Kennedy has told us
we are a go if we raise the money. I know this is a tall order but
(begging the forgiveness of our female audience members) "A coward dies a
thousand deaths and a brave man dies only once". I would rather go down
trying than cower in a closet. This is not intended as casting aspersions
on any individual or organization just saying I must proceed hastily to
succeed at all and I cannot afford caution.
Let's GO!

I heard Paulo's QSO with WA5KBH at my AOS and called CQ for the next
three minutes until the satellite entered the sunlight. The satellite
sounded perfectly normal.
And now we are beyond the summer solstice in the Northern Hemisphere,
so available transponder time on weekday evening passes will start to
increase.

We need PSAT IGates in Hawaii, India, China and anywhere in the Southern
Hempsiphere.
We did a look at the IGates that are successfully injecting PSAT packets
and did a map of them on the PSAT page:
http://aprs.org/psat.html
Notice that this map of stations are not all of the IGATES on 145.825 which
includes the ISS, but this is because the ISS is 14 dB stronger than PSAT.
So a station with an omni terrestrial antenna that picks up the ISS just
fine may not hear PSAT at all.
So if you have ever thought about being a satellite IGate, now is the
time.? And the ideal OMNI antenna for PSAT is a simple 19.5? vertical whip
over a large metal ground plane.? An even better one (+2 dB)? is a ? wave
vertical whip (58?) over a large metal ground plane.? And it is OK to keep
this antenna lower to the ground since it will not hear anything below 25
degrees anyway and in fact, the lower it is, with surroundings blocking it,
the less interference it will have.
IGATES that hear weak signal PSAT show on http://pcsat.aprs.org
All 145.825 IGATES show on the http://ariss.net page but they may not hear
PSAT.
Another reason to keep your Space IGATE antenna low is because they create
DONUT Hole Data NULLS.? Anyone who transmits a packet on the UPLINK TO one
of these sateliltes and is heard by an IGATE direct, will be ignored on the
downlink, since the packet has already been heard.? Therefere the digipeat
will not be recorded by the above FINDU.COM pages?

PSAT will be able to know where it is, and then we can activate its APRS

Subject: [amsat-bb] PSAT Igates needed
?
We need PSAT IGates in Hawaii, India, China and anywhere in the Southern
Hempsiphere.
We did a look at the IGates that are successfully injecting PSAT packets and
did a map of them on the PSAT page:
http://aprs.org/psat.html
Notice that this map of stations are not all of the IGATES on 145.825 which
includes the ISS, but this is because the ISS is 14 dB stronger than PSAT.
So a station with an omni terrestrial antenna that picks up the ISS just
fine may not hear PSAT at all.
So if you have ever thought about being a satellite IGate, now is the time.?
And the ideal OMNI antenna for PSAT is a simple 19.5? vertical whip over a
large metal ground plane.? An even better one (+2 dB)? is a ? wave vertical
whip (58?) over a large metal ground plane.? And it is OK to keep this
antenna lower to the ground since it will not hear anything below 25 degrees
anyway and in fact, the lower it is, with surroundings blocking it, the less
interference it will have.
IGATES that hear weak signal PSAT show on http://pcsat.aprs.org
All 145.825 IGATES show on the http://ariss.net page but they may not hear
PSAT.
Another reason to keep your Space IGATE antenna low is because they create
DONUT Hole Data NULLS.? Anyone who transmits a packet on the UPLINK TO one
of these sateliltes and is heard by an IGATE direct, will be ignored on the
downlink, since the packet has already been heard.? Therefere the digipeat
will not be recorded by the above FINDU.COM pages?

*Subject:* PSAT digipeating and Position Knowledge
PSAT continues to work well, both APRS and PSK31.? The downlink capture on
the PCSAT.APRS.ORG page captures most PSAT packets, but does not capture any
digipeated users if they use the ARISS path.? Although PSAT supports the VIA
ARISS alias so that users can use both ISS and PSAT without changing
parameters the FINDU page does not recognize it.
At this point it is unclear what paths that FINDU recognizes.
These paths are supposed to be digipeated by PSAT:
VIA ARISS
VIA APRSAT
VIA PSAT
VIA WIDEn-N
Here is what we know:
ARISS is not recognized by FINDU.
We are not sure if FINDU recognizes APRSAT
We are not sure if PSAT recognizes PSAT
We have seen VIA WIDEn-N work on FINDU
We have been busy with deadlines on our next satellite, but yesterday we
figured a workaround on the PSAT ORBIT and MA clock.? This morning we sent
the commands and will be watching to see if they work.? If they did, then
PSAT will be able to know where it is, and then we can activate its APRS
POSITION packets plus individual beacons over individual continents.
Although the S#OOOMM? telemetry was supposed to be ORBIT number and MINUTE
of that orbit, the clock is totally off.? SO instead of going from 0 to 95
minutes per orbit, the actual count is more like 0-61 minutes per orbit.
So, if this works, then MM is not real minutes, but is a number between 00
to 61 on every orbit.? And 0 should be when the satellite crosses the
equator (actually 5 South latitude)? on every orbit northbound.
Once we get that under control, then PSAT will know where it is, and it will
be able to report its own position.? And we can activate its attitude
control, and we can activate different bulletins over each continent.
