[Antennas] Re: B&W window antenna

 Bob:

   I like QRP and work it often with a FT-817.  Alot of fun.  The biggest difference between running 100 watts and QRP centers on your objectives.  If you want to maintain consistent communications with a known station, you need 100 watts.  If you are willing to go where the atmosphereics take you, QRP works fine.
