Drake R8-B
I have a question about this radio.
If I plug the AC jack in the wall and I have the 12 volt connection hooked up to a battery as a power failure backup will it damage the radio? Is there an internal switch to protect it from both sources being connected at the same time? Thanks Pierre |

The R8B runs extremely cool if you do that; you can even stack things on it then. -- Ron Hardin On the internet, nobody knows you're a jerk. |

I would not try this until you get an answer from Drake support. Phone: 937-746-6990 -- Telamon Ventura, California |

The 13 Volt input connects (through a diode) to the DC rail in the
Power Supply, upstream from all the regulators, downstream from the full wave bridge. It is always connected. The regulators would draw power from both the AC/transformer/bridge and from the battery/diode if both were hooked up.

Interesting question! When you find out, let us all know.

I got a response from Drake this morning. Here it is:
"There is a diode switch to protect each area so there should be no problem. Shane " I tried it and it seems to work fine. Pierre "David" wrote in message ...

Drake told me years back to put a big battery on those terminals to act as back-up power supply for my R8B. Down here in the lightning capital of the US we routinely pull the plugs, antennas and grounds from our gear to keep it from getting damaged by lightning discharges. The @#!&*# Drake R8B does not have any internal power back-up so to keep from having to reset the clock every time the plug is pulled an external power supply is needed. The current draw on battery during standby is about 0.64 amp so size a battery accordingly. Why Drake couldn't have put an internal back-up battery for the clock escapes me---then again, the R8B is a half-baked receiver anyway! RG |
