The steering is still mechanical, but the power assist is electric. Since
the gas engine is the Prius isn't always running, all the peripheral
systems traditionally belted or geared to the crankshaft of a gas
engine(water pump, A/C, power steering, power brakes, radiator fan, etc)
are electrically powered in the Prius.
BTW, both the gas engine and the 60KW / 50 HP AC electric motor are plumbed
into the water cooling system circulated by the electric coolant pump.
(The 50HP three-phase 440VAC electric traction motor is about the same size
as a normal 2HP AC motor that might be used in a big table saw or well jet
pump.)
It's not just the Prius either. Many new models are getting "electric
everything". My '06 Jetta TDI (turbo-diesel) also has electric-assist power
steering rather than the traditional hydraulic variety. Makes it much
easier to implement variable assist power purely in firmware.

I have a honda insight also hybrid. HOnda did the drive train differently
than toyota but still has a lot of electronics. I purchased it in sept
2000, have a 109,000 miles on it. It too has electric power steering.
I have been running most recently an Icom v8000 75 watts out on 2 meters
and with the insight no ill effects. There are a few discreet frequencies
that seem to have birdies but other than that it is reasonably rf quiet.
The radios have never caused any issues with the Insight at least on 2
meter frequencies.
It has a smaller than average 12 volt battery and I have killed a few of
them by leaving the radio on too long. The biggest problem was when my
tiny tracker stuck on when I had a kenwwod in the back and it spent the
night at full power.. dead battery next morning..
I dont know the specifics of the charging arrangement with the Prius. BUt
for reference in the insight the 12 volt battery is charged via a
144vold(insights High volt pack) dc-dc converter. I have heard that the max
12 volt out on the converter for the insight is about 60 amps.
If the prius has a similar charging arrangement then you would need to
watch your continuous current draw and make sure everything doesnt exceed
that but I would think there is enough smarts in the car to trip some kind
of a warning if it peaked over that even if its a circuit breaker. if you
are just talking your D7 current draw should not be an issue I would hope
anyway.
Depending on whether its the new or old prius from what I have read I
thought the early model prius actually had a 288 volt battery pack and the
newer priuses were closer to 400 volts.
Dont know if it helps but wanted to let you know that at least there are a
few hams out there with insights that have not had RF ill's caused.
Several years ago corresponded with a guy that actually operated HF with
his insight, had a telescoping HF vertical popping through the roof where
the broadcast antenna had been.

I cannot answer that directly, but one thing for sure is that NO program
should be logging packets to file WITHOUT ASSIGNING A TIME-OF-RECEIPT time
stamp. That was fundamental to APRS and overlooked in some programs. APRS
is tactical-real-time. Therefore many formats are not burdened with date
and time data, since by definition, it is NOW. There are position formats
that can include the day and time if needed, but most are sent without
them.
So any log files of any value of any APRS type program must save
time-of-receipt associated with every packet.
Soap Box off.

Subject: [aprssig] Dumb FindU question
OK, OK, OK.
I admit it. I'm pretty thick at times. I've been playing w/APRS for 5-6
years now with the D700. FindU is really neat and Steve (nice name), and
the others responsible (Bob etc.), deserves all the kudos possible. BUT
How in the heck are you *supposed to* do a search on FindU ?? The position
report page comes up with Steve on it. I have just been mungeing the URL
in the browser, substituting my call all these long years. Is this the
*right* way ?? Other sites have an "insert call here" text box. Is my
hat on too tight, or sumptin' ?
Straighten out this poor wayward soul.
I've played around with many of Steve's cgis, figuring out the components
of the URL to get other things to happen. I even can do things like
download ONLY the NWS radar W/position image (or other individual images)
so it loads fast on dialup without any other page stuff.
Also on the long term tracking page. See my recent (last 6 mo.) travels:
http://www.findu.com/cgi-bin/track.cgi?call=k9dci-9&start=4406&geo=usa.geo
Note the lack if Digis in western Nebraska and South Carolina, on the coast
north of Savanah where I stayed. Bummer.
73, Steve, K9DCI-9
P.S. If I can get the other three versions (706xx, TS-2000, TH-F6A)
cleaned up like I want, I will be doing an Excel spreadsheet that does D700
control and memory management. One line (row) per memory and all the power
of Excel to Copy/Paste/Auto-increment, etc. !
P.P.S. I even have a method of semi-automatically entering PL frequencies
into the 706 memories via serial port. Cool to see it work after hours of
keyboard work.
Yep! Excel does serial I/O... on a PC. (haven't tackled a Mac yet)
P.P.P.S. If questions, Email me _at_ arrl.net for faster response. I read
that email more often.

You are apparently just entering http://www.findu.com into your browser
and then navigating links to get to the map which defauts to K4HG.

The GPS interface is a 3 screw, plug in terminal strip on the rear for data
Tx/Rx/Ground. I have a Magellan 315GPS on my tracker and the NMEA is set
toV2.1 GSA at this time. The manual for the tracker does say that there
could be bi-directional NMEA in a future revision, but right now its only
NMEA in.....I would not be holding my breath for the updated firmware :-)
I should have mentioned earlier, I use mine on HF, hence the Rx "lock in"
feature on receive.....if you use the unit on 300 baud HF Packet. It also
has a "robust packet" mode which is meant to be more reliable for comms,
but its an SCS proprietary development, no other TNC has it, except their
other models, the PTC-IIex & PTCPro etc, which I also have here.
