There's one more thing to consider. I contest at the 5W level, and work almost everything I can hear eventually. That being the case, 100w might let me work those stations a bit sooner, but once I've done that, those 100w won't help me hear any better. Gotta hear them to work them.
Money spent on an improved antenna system would far outweigh money spent on extra power, especially at the 3dB increase level. 73, Bob N6WG ----- Original Message ----- From: "Brian Lloyd" <[EMAIL PROTECTED]> To: "Elliott Lawrence" <[EMAIL PROTECTED]> Cc: <Elecraft@mailman.qth.net> Sent: Thursday, May 10, 2007 11:58 AM Subject: Re: [Elecraft] Yaesu FT-2000 v K-3? > On May 10, 2007, at 10:06 AM, Elliott Lawrence wrote: > > > One thing that would help would be an additional option for a 200w > > capable radio ---- the K3D!!!
