One other note,? the FS3 receiver is very sensitive.? In the absence of
interference it can make bits from an uplink of about 5W into a whip.?
As a further comparison, just after launch when we tested the FM
repeater (sadly no longer working), we talked 3W HT to HT with 1/4 wave
whips across a parking lot using FM voice full quieting. It still hears
just as well thanks to the excellent SpaceQuest radio hardware.
So 15W or so to a mobile whip should be more than enough under nearly
all circumstances.

It is, perhaps, a convenience to go this route. However, in terms of
efficiency, small generators win every time.
Just think about all the systems your car is running (fluids being
pumped around, electrical loads) and the fact that a gasoline engine at
idle has terrible thermodynamic efficiency. Quoting a 2008 paper[1] by Remy:

Now, that's just the alternator, discounting all of the other stuff
bolted to the engine. Compare this to my back-of-the-napkin calculation
of $0.70/kWh for the EU2200i at max rated load[2]. The car seems like a
win, but it won't be due to the "other stuff" eating energy.
I can attest to the quietness of the EU2200i, as I own one. However, a
solar panel is even quieter. :-)

Mark-
Thanks for the reply. I have sent an email to w0dhb about the availability
of an updated FlexSatPC. I note that his original download site has been
taken down.
I have reconfigurated SatPC32 to bypass using FlexSatPC and am still
encountering the stalling of SatPC32 once a satellite passes the 0 degree
elevation threshhold. I suspect there is a setting that I have overlooked, I
just don?t know where.

You mentioned that the clock stops. Upper right?
When you loaded the newer version, did you use the backup facility to
restore your settings? If so, try doing a clean install, and then
reconfiguring manually. Painful, but I have had something odd which was
traceable eventually to a corrupted configuration file.

The facts are that we tax payers pay $20 billion dollars a year for Gas
and Oil subsidies.
Divide that by the number of gas vehicles sold per year and you get $3300
subsidy per gas car.
The article you quote ignores that fact and uses flawed one sided
comparisons throughout.
If the government does not incentivize us to move away from high emission
cars, who will?
Here are a few truths ignored by that oil-company wall-street biased
article:
* 53% of all EV's in 2018 now cost less (w incentives) than the average
gas car ($35k)
* 50% of all plugins now have ranges over 350 miles
* EV's sales are growing by 50 to 100% a year. Gas car sales are falling
since mid 2018
* Thank heavens that those who can afford them are buying them.
* Or, Does the author want poor people to buy EV's so others can keep
driving gas?
* EVs help everyone to breathe cleaner air. What are others doing for
clean air?
* There are 6 EV pickups in development (higher torque, towing, and
worksite 240 VAC)
* There is an EV model for almost everyone except the daily road warrior.
* EV's can drive the American Average 40 mi/day from just 12 solar panels
only!
It's an exciting time. I cant believe I have long enough to see solar half
the cost of utilities and EV's that are now better, faster, cleaner and
cheaper to buy, cheaper to operate and cheaper to maintain than the
average gas car. And it makes a great power source for Ham radio (except
for the RFI)...

An apparent complaint about clean air EV incentives, while ignoring the
petroleum subsidies of about $3300 per dirty-air gas car. Which is now
about the same as the $3750 Tesla incentive. But, the Tesla incentive
will decrease by half in the next six months and then zero. While the
dirty gas car continues to get subsidized by tax payers for decades...
We should end this thread as off topic, but need to correct any
misinformation. Bob

Seems a bit overkill when a marine deep-cycle and a solar panel will run
you about $500, no? ;-)

Terry,
The beacon transmit a short film (DATV) about QO-100 history.
There are several OM?s higher in the WB transponder also transmitting DATV.
I receive all this very well in 3B8.
3B8FA is also quite active on the NB transponder on SSB and SSTV from
Mauritius.

Hi,
I?ve been having a look at the QO-100 Wide band Transponder on the web sdr.
See: https://eshail.batc.org.uk/wb/
For those of us that don?t live in the footprint, does anyone have a screen
shot of what the beacon picture is?

I support a laissez-faire approach when it comes to FM transponder use.
Not everyone chases grids. Not everyone chases DX. There are busy passes
and there are slow passes. It balances out.
When I am out roving, I don't sit and call every station on the pass. I
normally give my callsign once and wait for others to call me. On
average, if I'm in a desired grid square, I might receive 20 direct
calls. If most stations are hearing adequately and adhering to
generally-accepted operating norms, there is plenty of room in a 11-13
minute pass for twice that number of QSO's.
Last week, while I was operating from a remote grid in West Texas,
another station was operating from desired grids further northwest.
Between us there were nearly 40 clean QSO's, with the potential for
more. It was amazingly orderly for an FM transponder - on a weekend!
Any transponder is a shared, multi-user resource. Except for emergency
communications I don't believe consensus exists to prioritize use for
particular groups (backyard/handheld warriors, rovers, home stations,
club demo's, hamfests.) Who would make that determination? It would
likely be unpopular. I try to prioritize the young people, Scouts,
demos, and new calls but that is MY personal preference. HEARING the
satellite is critical but LISTENING(comprehension) to the cadence of the
pass is equally important.
Often I listen to transponders and hear very few stations. Time of day
and footprint coverage are key elements to determine when a transponder
will have activity. If someone new is expecting to make their first-ever
QSO on a Saturday afternoon pass covering an entire continent, their
expectation might not be met.

figure are already available ( http://bit.ly/figureSat ). Answer are
mainly from france.
It should be very interesting to have the opinion from other country.
Please take less than 10 minutes to fill this survey :

Results should be made available to all other AMSAT sociaty.
Thank you for your Help
