Armchair Lawyer Time!
97.113 (a)(3) Communications in which the station licensee or control
operator has a pecuniary interest, including communications on behalf of an
employer. Amateur operators may, however, notify other amateur operators of
the availability for sale or trade of apparatus normally used in an amateur
station, provided that such activity is not conducted on a regular basis;
Sounds to me like since a Hamfest is an event, you could slide by. The
phrase "on a regular basis" stands out here.
A Ham Radio store is a full time, brick and mortar operation, and thus any
advertising of that store would be prohibited.
I would also say that since, as previously mentioned, these are employees of
HRO, you don't even get past the first sentence.

Pat,
This would work if a person had a dual band and was monitoring 146.520 and
had ARPS on 144.390. I normally travel with the 'A' side set to APRS and
the 'B' side set to a local repeater. So if you cal me on voice alert on
APRS I will hear you and we can QSY. But if you call me on 146.520 I more
than likely will not hear you.
73,
Dave N0EOP

As I mentioned in the CA-APRS list, my problem with this particular bulletin
is that it appears to come from the store itself - there's no indication in
the status text that it's posted by a club - and unlike 'for sale' listings
on your weekly net, this is advertising items *from the store*, not from a
club or an individual. Even if it is a club responsible for posting the
message, they're not advertising that the club has equipment - they're
saying that the store has it, and if that doesn't count as a commercial
advertisement, I don't know what does.
I'm not one to encourage blind adherence to the absolute letter of the law
to the exclusion of a bit of common sense (we've got enough armchair lawyers
around here already who would rather fight over interpretations of
oddly-worded, vaguely applicable regulations than do something productive
with the hobby) but this case would seem to fail the most basic test of
whether it appears to be consistent with the non-commercial spirit of
amateur radio.

Subject: [aprssig] Prius
There was some PRIUS discussion on the sig that I completely ignored.
Last night my car blew up, and out of the blue, I am looking for a used car
for my APRS addiction, and I was surprised to find PRIUS hybrids on the
used market at comparable prices to other used cars.
So what was the bottom line about PRIUS and APRS (and particualarly, I am
interested in the PLUG-IN conversions...)? From what I can tell, one would
want a 2004 or later, since it has a CAN-BUS serial bus that you can tap
into with your laptop and communiate with everything from the tailpipe to
the engine.

The original APRSdos includes an overlay file of all such stores including
all radioshacks. By just one-finger pressing the keys M-O-S
(Maps-Overlay-Stores) all of the stores would show up on your map. Drive
right over and pick up what you need...
>I think someone well known and respected in APRS..

You bet, the concept of putting a HAM store on the map was all part of the
original APRS concept. Remember, "tactical situational awareness" was the
whole concept of APRS... But "advertising and pushing product" seems to me
to be across the line...

Exactly! But I would add two steps:
1) First call on 144.39 because you *know* he is there
2) He could easily have his monitor on some repeater
3) You *MUST* say "...calling Voice Alert" on 144.39
4) Say "Switch to 52"...
Number 3 is extemely important. Other wise the called party just hears a
voice calling and unless the words "voice alert" are included in the call,
he thinks it came from his normal voice side of the radio. He may be on
146.94. He responds on 94, and you don't hear him, and he does not hear
your call on 52.
So you must call on 144.39 (where he is listening)
You must announce "voice Alert" so he knows where you came in
You must then agree to a QSY.
Thanks

Subject: Re: [aprssig] Prius
Last weekend I was traveling with my wife near Philly PA. She has a hybrid
Toyota Highlander. I had a D7AG with a battery eliminator connected to the
cigarette plug, my Garmin 60CSx also connected to the same plug and the
cell phone connected to also the same plug plus a short mag mount antenna
on the roof. This system worked well and I the grandchildren could follow
our approach on the web. I received many signals, as I was curious I did
not set a range. I received your signal too on Sunday towards noon but the
weather was too bad to send anything. I was just lucky I managed to glance
at the D7 at the right time. We were about 20 miles apart.
There was no interference, noise or otherwise problems with this setup.
Sure I was not drawing much power with the HT but since it was a less than
ideal setup, I thought you might want to know it worked well.
Good luck with the Prius.

1) The Prius main power system is a 240 VDC MNiH battery pack that powers
a 440VAC 3-phase 60 Hp water-cooled electric motor. (The electric motor is
plumbed into the radiator just like the gas engine.) A 240VDC to 440 VAC
inverter is integral to the electric motor. This HIGH-POWER DC-AC
conversion creates LOTS of broadband white noise on the HF bands which gets
worse when you hit the brakes (which makes the motor run backwards as a
generator. The noise shows up even at VHF where it registers about S-1 or
S-2 on the D700 S-meter.
2) The Prius 12 VDC system is a very vestigial affair intended to power
just the radio, lights and computer display. It uses a 240VDC-to-12 VDC
stepdown converter that can provide about 49-50A but the 12 VDC battery is
a 20 AH device that looks like it came from a motorcycle. It's main
purpose to power up the computer electronics that need to boot in order to
start the hybrid power system. (In the Prius, EVERYTHING is fly-by-wire.
The power steering, the water pump, the power brakes and the air
conditioning are all powered electrically off the 220 VDC system which in
turn is controlled by the 12 VDC powered computer systems.)
In my install in a 2006 Prius, I installed a second 50AH deep-cycle battery
with an intelligent voltage-sensitive isolator to run the computer and
radios engine-off. The DC-DC converter has no problem charging the second
battery, especially because the power-FET-based Hellroaring Technology
battery isolator has inrush limitation.
3) I have observed no interference problems TO the Prius' complex
electronics at all, even with 100W on HF or 2M.
4) When you park, but don't shut down the hybrid power system (you don't
start this car; rather you boot it), the gas engine shuts down but the
control systems remain live if you don't push the "OFF" button.
In turn, you can continue to run the electrically-powered A/C or other
devices from the 240 v battery. Every time the battery drops to about 210
volts, the gas engine will start up by itself, run for a minute or two to
recharge the battery and then shut off again. It can repeat this process
endlessly. The 240-to-12VDC down converter continues to run, making
available 30 amps continuously. Very handy when operating mobile-at-halt
for some special event. I've actually slept overnight in the car in
air-conditioned comfort (in Iowa in August!) with the APRS laptop and radio
running, and used only about a half-gallon of gas.
This has some interest emergency power potential. The website
explains how many high-power computer-room UPS systems actually use 240 VDC
batteries. By connecting one of these devices (without it's battery) across
the Prius 240V battery, you can extract a continuous 10-15KW of AC power
( ! ) from the Prius. Again, every time the battery pack drops to 210 VDC
or so, the gas engine just starts up and recharges it. [And the Prius gas
engine at idle is virtually silent unlike most gensets.]
I have plans for some nifty no-holes antenna mounts that I designed to
install on the Prius if interested.
5) A third-party adapter can adapt the car's color LCD "multi-function"
display to display external NTSC video sources; i.e. a built-in monitor for
my mobile SSTV LiveCAM.
