I found that even with the drag components removed, the damping oil
in the encoder bearing of my RX340 made its action significantly
stiffer than I wanted, so I took the encoder apart and flushed out
the damping oil. I lubricated it with 10W30 Mobil 1. If I did it
over again, I'd use something just the merest touch more viscous than
that -- perhaps 60W racing oil. I think the 340 knob may be the same
"weighted aluminum" knob that is available for the transceivers. And
yes, it's appalling that the knob skirts are so far off center.
Best regards,
Charles
