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.

> Good solution.  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.

>> I stretched out an O-ring a bit and managed to slip it over the tuning knob on my KX2. 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.
