That said, it is apparent that the quality-control problems have not been solved, Eton's spokesperson(s) to the contrary. There are two solutions: one is to return (and keep returning) defective units until you get one "right;" you must insist that the company pay for return shipping (inquire about this before the purchase) or buy it locally. (If you purchase one from Universal Radio, they will test it for you on request before shipping; this ensures that your particular unit is satisfactory.) Second is to buy a Drake-refurbished unit as available. Not only is that cheaper, you know it will be "right." Several companies offer this. Good thing I'm so close to where Universal is located. I however was lucky enough to get a decent unit. :D Jeff Seale Louisville, KY S800, YB-550PE, Pro95, BC780XLT |

Can you tell us exactly when you attended Wayne State? Or is that another Fat Boy secret or fabrication? |

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?

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.

There must be something in the owner's manual regarding the maximum input voltage.

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. bball |

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. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
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. Lawrence wrote in message . ..

I have a JPG copy of the '800' schematic so I'll check it out too. 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. -- Telamon Ventura, California |
