Re: Higher Power Amps
Personally I want an amp that will load at 1500 Watts. Like my Alpha 87A or before it my All would state RF-3230--both had loads of design margin at 1500 W output. That give me comfort that the amp going to last a very long time.

Hope it holds up. The lack of knob weight on this most amazing little rig is the only genuine physical design gripe I can come up with. would be nice if it was a slightly heavier and rubberized grip.. pretty tough with such as small knob though and may be cost prohibitive. Your solution make lots of sense to bridge the gap. a push button encoder to add another route to menus would be another afterthought. > ________________________________________ > From: Elecraft [[hidden email]] on behalf of Doug Millar via Elecraft [[hidden email]] > Sent: Thursday, March 30, 2017 3:29 PM > To: Elecraft Reflector > Subject: [Elecraft] KX2 Weighted Knob > > Hi, > Well, I might have done it.

It now sits about 1/16th of an inch down from the top face of the knob, and it has greatly enhanced my ability to manually scan through the frequencies. I just put the tip of my right index finger at the side of the knob so that I'm touching both the O-ring and the upper edge of the knob, and that allows me to scoot merrily through the frequencies. The O-ring is black so it blends well with the rig and is barely noticable. >> ? >> Emory Schley >> N4LP >> >> >> ------------------------------ >> >> Message: 21 >> Date: Thu, 30 Mar 2017 16:12:14 -0400 (EDT) >> From: [hidden email] >> To: Elecraft Reflector <[hidden email]> >> Subject: Re: [Elecraft] FCC R&O approves 630m ham band >> Message-ID: >> <[hidden email]> >> Content-Type: text/plain; charset=utf-8 >> >> Hi Wayne, >> >> >> The product we need is a companion 630M 100 watt amplifier for >> Lowfer enabled K3 transceivers.
