[Elecraft] Different KX2 VFO A knob?

[Wayne Burdick]

Bob,

I strongly recommended *not* putting any other VFO A knob on the KX2. The current VFO knob was designed specifically for the KX2, matching the exact amount of space available, and keeping it low-profile. 

If you add a knob that's even slightly larger in diameter, it may hit or overlay the switches or LCD bezel. If you use a weighted knob, you'll risk shortening the lifetime of the VFO A contacting encoder. It's a high-quality encoder with a specified lifetime of over 100,000 revolutions, but a weighted knob could stress the shaft unnecessarily.

The KX2 has a couple of useful features to minimize the amount of VFO knob twisting you need to do to move around the band:

- If RIT and XIT are OFF and the "OFS" LED is lit, then the OFS/VFO B knob will move the VFO in coarse steps. (The size of coarse steps is defined by MENU:VFO CRS).

- There are at least two tuning rates available in each mode (RATE switch).

- You can jump to a specific frequency using direct frequency entry (FREQ switch).

- Scanning can find signals on the band -- even fairly weak ones -- without any use of the VFO A knob at all.
