Hi All,
In case anyone else is disenchanted with the general "feel" of the main =
tuning knob, I did lots of experimenting to improve it. Had great =
success. This remedy also works exactly the same on the uneven drag on =
the TS-950SD knob.
The OMNI-6 adjustable drag mechanism is rather mickey-mouse in my =
opinion. It can produce an uneven amount of drag during one revolution. =
This annoyed me to no end. (It was worse on my "spare" rig: TS-950). It =
also would produce a slight screechy noise from time to time, even =
though I spread teflon lube on the rubbing plate behind the felt-padded =
bronze arms.=20
So, I played "operation" and performed the following "final solution:"
1...take knob off and take the bronze arms off.
2...bend bronze arms backward from the way they were. Now, when you =
re-install the screws, they will apply tension to the skirt, locking it =
permanently in place.
3...apply a coating of rubber cement to the inside, back of the knob. =
(If you use the type of rubber cement such as is intended for gluing =
paper with, it can be removed by rubbing it with your finger, in case =
you should chicken out from the project).
4...while cement is wet, press a layer of cotton, from a pill bottle, to =
the cement. You can remove some of the cotton a little at a time to =
adjust distance from the skirt to panel after the cement dries, so a lot =
of cotton is OK for now.
5...apply small amount of teflon lube (Radio Shack precision lube pen) =
to the plastic friction rubbing surface on panel behind the knob. =
Re-install the knob.
6...the drag adjustment is now accomplished by adjusting the distance =
from knob to panel. Coarse adjustment for final distance is made by =
removing some cotton.
7... Wow! The tuning knob now feels like silken velvet. Just perfect, =
and it has an even amount of drag all the way around a revolution. I =
prefer mine with very, very light drag.
73, Roy K6XK
