Olli, The SHIFT/LO control, etc., are mechanical encoders with a typical rotational life of 100,000 rotations. The are easily replaceable, and we can send you as many as you need. I believe the price is quite low. I don't believe is is possible to clean them, as they are sealed.
In contrast, the VFO A and B encoders are optical, not mechanical, and they are specified at 10 million rotations. But the cost difference between optical and mechanical is huge (about 40:1). The mechanical encoders are very small, fitting in the available space, and are a pragmatic choice for the function controls. 73, Wayne N6KR On Nov 11, 2014, at 8:57 AM, "Olli Tuppurainen" <[email protected]> wrote: > Has anyone figured out how to clean or fix front panel encoders (SHIFT/LO , > HI /WIDTH) ?
