Yeah, I just scare the hell out of people. Yup that's what friends,
family and coworkers say about me that I'm just plain scary. No telling
what I might do.

I'd like to know what I did to earn the "Nazi" part and why I'm sooo...
scary to you. If you need to depersonalize the reason through the device
of your making like "your students" feel free.

Well at least you still have some room in your head for a little humor
resting beside that huge imagination.

I'd say you have a defective unit. As far as the display not
displaying the letters USB - that was taken directly from the Drake
SW8 which also cannot display the letters USB. Some of the early
sets, including mine, have a bad adjustment for the battery indicator
and it flashes, like you say, after about 3 hours of use. That was
corrected on later units, so I understand. The other problems you
have seem to be on your set as I do not have those problems with mine.

I've run my Sat 800 (second series) for the last year on a car
battery. The supply voltage as listed in the manual is 9 volts, but
cast in plastic above the supply input jack is "9-15 volts". The radio
is very happy with even a fully charged battery at 13.8 v and will last
for *weeks* of my teenager listening to loud rock music between charges.

9-15 volts; interesting!

I bought one of the first available S800s from Sharper Image (Still
works like a champ with a very quiet 400' loop, everyday). The
plastic on mine, by the input, reads DC 9V.

I do run mine on a garden tractor/snowmobile battery but use an RS
DC-DC converter to get 9V @900ma output. In addition I keep a 50w
solar panel connected to the battery. Maintenance on the whole deal
is to add a little distilled water to the battery every couple years
and occasionally soap/rinse spray the solar panel on the roof.

Was tempted at first to chance running the receiver straight off the
12V too, but opted to be gentle on the components. Any comment out
there on detrimental effects of higher voltage use? Or, what's best
for the radio.

Great radios ain't they?

Sat800, 400' loop @15' height, AD Sloper (not as good), MFJ 959B for
good matching, switching, occ amplification.

The only componant(s) that would experience the higher voltage would be
the main voltage regulator which is apparently designed to handle an
input voltage of up to 15-V. The '800' actually has an internal DC to DC
converter which steps up the nominal 9-V input voltage to 15-V for
certain circuits that need a higher voltage. There must be something in
the owner's manual regarding the maximum input voltage.

Now you have me wondering if my Drake-SW8, which was the prototype for
the '800', could be run on 12-V instead of 9-V. I'll have to check the
manual and schematic.

A practical implication here is that if one desired to use the huge
S800 as a portable, a practical power supply might be a long, slim 12V
gell cell/SLA battery to fit in the battery compartment. Two 6V 1.3A
(3-3/4x2x1") gell cells will almost fit in there after removing the
receiver terminals. I'll experiment on playtime but suspect only
about 4-5 hours on the series gell cells. Otherwise, it's not that
difficult to saw a hole in the battery compartment and put a larger
gell cell in there.

Please check SW8 power and let us know if you think 12V may be
allright.

You wouldn't have to use the battery compartment. There's enough room
inside the '800' case, on the speaker end, for a 12-V rechargeable
battery.

The SW8 manual says the power supply voltage should be in the range of
7-10 volts. I gave the schematic a cursory look. The nominal 9-V power
input doesn't seem to pass through a common voltage regulator before
branching out to other voltage regulators or unregulated circuits. If
this is the case, it would require installing a primary voltage
regulator so it could handle a 12-V input. That wouldn't be difficult
using a three pin IC regulator which was set to operate at 9-V but the
power loss in that regulator would decrease the operating time for an
external 12-V battery. I'll study the schematic some more to see what
the options may be. Someone said the '800' has writing on the rear of
the case that indicates it can handle up to 15-V input. I have a JPG
copy of the '800' schematic so I'll check it out too.

I still like C.Crane's NiMH "D" cells. 6 fully charged ones give 30-40
hours of play time. I had my battery meter adjusted to work with 1.2V
batteries instead of 1.5V so I don't see the blinking "BATT"
indicator, but the indicator has no effect on the run-time. With these
batteries, no modification to the radio is necessary.

My Sat 800 says 9V on the back. The manual says 9V also.

When you look at the schematic you will find the input DC is routed
several places and not all of them lead to a regulator.

My position would be to only use a 9 volt supply. Why risk damaging
the radio by providing more than it can use?

Linear switching regulators are lossy and will dissipate more heat the
higher the input voltage relative to the output voltage. It might get to
hot and fail after a while. You only need to be slightly higher than the
minimum drop across the regulator plus the output voltage. There is no
advantage being any higher.
