Hi,

Thanks to K5MAN for the AG-35 manual copy, including schematic.

For the benefit of anyone else considering an AG-35, I thought I'd pass along what I've found so far.

I was able to read most of the scanner manual pages 100%, and from what I can see, the AG-35 uses a 78L08 voltage regulator. Seems that the TO-92 package was/is the most common, so I doubt that there's really much heatsink area?

The datasheet for the 78L08 shows that a maximum of 23 volts should be applied to the input, and the AG-35 manual specifies 9-15 volts input. I'm guessing that Icom under-rated the voltage input due to the small heatsink area?

Anyhow, I'm a little worried that my AO-40 bias tee will run the AG-35 hot. Guess I'll put a little bias-tee together and use 13.8v station power.. Now just to find the time! <grin!>
