Hi Ruth, Matt .. List,
I don't do demostrations to get more ops on the birds.. I do it cause it is
what tickles me within hamradio.
It is what Sean mentioned "awareness"
Yes I do try and help those who asks.. If someone asks it is most likely
due to they have some level of interest.
If everything goes at planned I'm going to do a demo for the SARA group (
http://www.radioham.org) September 9th staying around 1400z, might try
FO-29.
Not trying to hijack the thread.

Does anyone have a SDR# I/Q wav file of AO85 Telemetry?
AO85 (Fox-1A) should have a downlink that can be copied with an RTL-SDR
Dongle.
In this part of the world, you need to trigger the repeater to turn on the
Downlink and so far I haven?t been able to do this.
The 2 minute timer is a bit like chasing a needle in a haystack.
I?ve tried Patrick, WD9EWK?s HDSDR files but can get any decoded data.

Presenting to others is about raising awareness in your activity. One will
not be interested in something if one doesn't know it exists.
You will not get 100% interest in your presentation. However, you may get a
few. Raising the awareness of a few is better than not trying. Play the long
game; it pays off in the end.

Ruth, will give it a go from DM14.
and thank you for your demo. The exposure can be invaluable to those few
that are inspired to chase satellites.
Clint's K6LCS demo many years ago did it for me, then Patrick's (WD9EWK)
first response to my call during my
first demo during a JOTA clenched it. Thank you to all you Elmers out there.

My HT on a rubber duck just north of Georgia picked up 12 APRS balloons
during the eclipse .
When I got home, I counted 244 APRS Balloons on Eclipse day on FINDU.COM.
Subtracting out the 96 from other parts of the world that day left 148 over
the USA. But looking at the map, I only could find about 46 along the
track? Where were the others?
I cant get a plot of all the USA ones since the filters on APRSFI wont work
that big.
Looking for someone who can plot all the APRS balloons that day on one map?
Mark, KE6BB posted a plot of all the "Flight" symbols during the eclipse.
Most are balloons, but a few aircraft mixed in as well. But Ill have to
post it on a web page to share it with the group.

Hello Bob!
You're more than welcome to use the image that I included with a tweet on
eclipse day if it's useful to you:
https://twitter.com/scott23192/status/899694435168133120
... it was obtained from:
https://tracker.habhub.org/#!mt=roadmap&mz=4&qm=6_hours&mc=40.79427,-83.68583
... where I often check to see if there are any balloons in my area that I
might be able to receive on 144.390.
73!

HI folks,
AO73/FUNcube is now in amateur mode for the weekend with the transponder on!
As normal, plan is to revert to normal mode on Sun PM (UTC).
Please see below for all FUNcube mission info
73s Jim G3WGM and the FUNcube team.
++++++++++++++++++++++++++++++++++
FUNcube frequencies and other details
++++++++++++++++++++++++++++++++++
AO-73 FUNcube-1
The transponder is normally operational only when the satellite is in
eclipse, ie the solar panels are NOT being illuminated. During weekends
(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.
When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power. During holidays,
eg Christmas, New Year, Easter, etc, the transponder maybe activated for
extended periods. Watch AMSAT-BB for announcements which are usually made on
Friday evenings (UTC)
The nominal transponder frequencies are:
Uplink: 435.150 - 435.130 MHz LSB (Inverting)
Downlink: 145.950 - 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK
(The passband may be up to 15kHz higher depending on on-board temps. Lower
temperatures give higher freqs!)
FUNcube-2 (aka FUNcube on UKube)
The FUNcube-2 sub-system continues to operate autonomously and, almost
continuously, in amateur mode. The transponder is operational and the
telemetry downlink is functioning with about 70mW output. The FUNcube-1
Dashboard does not correctly display the telemetry but it does correctly
decode the data and uploads it to the FUNcube Data Warehouse from where it
can be examined. Most of the real time data channels are operational and
these include battery voltages, temperatures and ADCS data coming via the
main On Board Computer (OBC).
The transponder is interrupted for a few seconds every 2 minutes when the
other transmitter sends its CW beacon and, occasionally, for a few seconds
when the main OBC reboots (approx seven times each orbit).
The nominal transponder frequencies are:
Uplink: 435.080 - 435.060 MHz LSB (Inverting)
Downlink: 145.930 - 145.950 MHz USB
Telemetry Tx: 145.915 MHz BPSK
(The passband may be up to 10kHz higher depending on on-board temps. Low
temperatures give higher freqs!)
EO79 FUNcube-3
Due to power budget constraints the transponder cannot be operational 24/7
and an orbit specific schedule has been developed. The transponder will
commence operation 27 minutes after the spacecraft enters sunlight and will
stay on for a period of 25 minutes. This schedule may be modified in future
months as a result of experience.
The nominal transponder frequencies are:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB
Further detailed info on EO79 transponder frequencies is at:
https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-o
peration/
EO88/Nayif-1/FUNcube-5
EO88 is presently operating in autonomous mode. The transponder is
operational when the satellite is in eclipse, ie the solar panels are NOT
being illuminated.
When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power.
The transponder frequencies are:
Uplink: 435.045 ? 435.015 MHz LSB (inverting)
Downlink: 145.960-145.990 MHz USB
Telemetry Tx: 145.940MHz
All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very
grateful for the assistance given by Innovative Solution In Space Bv, The
Netherlands.

Anyone to solar power their Satstation in Maryland?
I am about to buy a truckload of solar panels for my church and various
projects. Delivery from Miami to Annapolis Maryland is several hundred
dollars so if anyone local wants to pile on and get some panels, Ill
consider adding some more.
These are 285 Watt Trina panels 30v at about 7 amps. 65? by 39?. 40 Lbs
each. Black frames.
Cost is about $100 each.
You must pick them up from Annapolis.

It is SUNELEC.COM They have unbelievable deals. They also ship from
Arizona I think... They have tens of thousands of panels for prices
typically between 30 to 50 cents a watt.
Solar power for the home is now way under the cost from the utilities, but
only if you are grid tied. If you try to store the energy in batteries
every day, your costs for the system will triple and you will have battery
maintenance issues for life. Plus not enough power in the winter, and too
much in the summer.

So it is so cheap, but here are many considerations....
* Solar energy now costs much less than the utilities if grid-tied.
* But only in states where the utilities are not sleeping with the
politicians
* You cannot grid-tie unless you have a licensed electrician do it and get
all the permits. You will pay around $3/watt installed.
* Hint for DIY types: Contract for a very small system. Then add your own
panels later (while fully following NEC code).
* Going off grid makes no economic sense whatsoever if you have the grid.
You will pay three times more for the batteries and never recoup the
investment as you always have to maintain and replace batteries for the
rest of your life!.
* Solar panels are excellent for remote sites where you have no grid and
having battery solar power is worth paying triple what it is worth.
* Solar panels are great for RV's, Boats or Electric cars... ANYTHING that
already has to have a battery anyway, may as well charge for free.
** A small solar panel on the house for the shack makes no economic sense
whatsoever. You have the grid, so just charge the shack backup battery
from the grid. Don't bother with solar. Also, every single day the grid is
UP, you are not using the backup battery so your solar is producing
absolutely nothing anyway 99.96% of the time (In Maryland anyway, that is
the grid reliability)..
** But if you plug that solar panel into a small 500W Grid-Tie inverter
that just plugs into a home outlet (cost under $100 on ebay) then you DO
get full retail value from the solar everyday for ever AND you can use the
panel direct when the grid goes down. butt don't get greedy...
** But ONLY if you never backfeed more than you are using every minute of
the day. If you ever backfeed more than you use, you will pay double for
it. ALl non-NET-meters charge for electricity going through the meter no
matter which way it goes! So you pay when you over produce and you pay
again when you draw it back out later. That is why you MUST have a NET
meter to have any hope of economical solar in bulk.
** Thus, a plugin grid tie more than one or two panels will end up COSTING
you for every watt you over produce. So, again, the only economical solar
is whole house legal net-metered grid tie. And it is so cheap it makes no
sense not to do it that way.
But if you still want to have a single panel for $100 its great to have 30
volts at 7 amps from the sun, even if you just waste it. But then having
to pay $100 for shipping for a $100 panel doesn't make a lot of sense
either...
Your mileage may vary.
