om...

That's very useful, thanks! I downloaded the program and think I
understand it well enough to plug in the numbers. I do have one big
question though. How do I measure the impedance? I've got a basic
VOM but that's it as far as test equipment, and my knowledge of things
electronic is pretty basic.

Oh, yeah, I didn't consider that your antenna is not 50-ohms. How long is
the antenna, and what frequency band are you using? 72 MHz? When it comes to
calculating what your antenna looks like impedance-wise, there are others
here more knowledgeable than me and I hope they jump in! I wonder how well
shielded the transmitter is, also. If not well shielded the interference
could just get in directly and the BP filter wouldn't help. There are
devices that allow you to measure an antenna's impedance, but they cost
about what your transmitter cost.
