“The circuit is specifically designed to amplify the output of 7mW to 10mW WBFM transmitters (wide band) to a final level of 250mW to 300mW”
It sells for around $20.00
Might be an easier solution to implement. Also, to give an idea of mW vs range, when I tested the [url=http://part15.us/modules.php?name=Reviews&rop=showcontent&id=2][b:f86d99735b]Compact Synthesized PLL FM STEREO Transmitter -10mW[/b:f86d99735b][/url] I used a simple dipole high and in the clear, and as I said in the review, “I was getting a car radio range of about 3000 feet north-south, and 2000 feet east-west. Portable radios couldn’t pick me out of the cross talk on the band as well, and I got about half that on the portables.”, so 250 mW into a good antenna just might do the trick.
As always, let us know how it turns out 😀
[quote:f86d99735b]By the way, RadioheadC, thanks. I thought that Part 15 FM used to have a 100mW/1meter standard. Apparently I’m not the only one.[/quote:f86d99735b]
