Post subject: Modifying A Baby Monitor - More Wattage
Posted: Fri Jun 10, 2005 9:21 pm
I'm a licensed ham and I need
some diagrams or instructions on how to mod a 49 MHz baby monitor
to put out more power. It's currently at 100 mW. I'm looking to
boost that up to at least 500 mW.

I hit the
send button too soon.
I've got a replacement crystal that'll
go in as soon as I mod it so that it transmits in the 50 MHz band.
I'd appreciate any input on this.

In my experience, baby monitors come in
1. Discrete designs (perhaps with some IC's)
2. Single-chip designs
In the first case, you might be able
to modify the PA stage for more power. In the second, you probably
can't do anything. That's how the FCC wants things - hard to make
mods that make them illegal for the intended use.
check to see what you've got, and let us know.

I don't get what you're saying. "It's hard to make
mods that make them illegal for their intended use." What does that
mean? If it's operating under part 97 rules in ham bands then it's
legal. I can modify and homebrew anything I want as long as I follow
the rules for part 97. Now, as far as the actuall device. This thing's
got a a simple PCB board. There's no IC.
