[Amps] Low Pass Filter capacitor ratings for 1.5kw level

[Will Matney]

Jim,

Yes, that's the one I was thinking of, I just couldn't remember where I seen it at!
I think the design is a good one, and it's sure well made. For everyone, the cutoff 
starts after 6 meters, so keep that in mind. If you want cutoff after 30 MHz, 
use the design, but change the component values. The software makes it easy.
Using a filter after the transceiver is a good idea along with the one behind the amp.

Best,

Will
