Default Backlash?

Is backlash in tuning mechanisms necessarily a problem, because
a little bit of looseness in the drive means that an accidental nudge of
the
tuning control won't cause a frequency change, as it would if
tightly-coupled and backlash free?




you trained for backlash on a Trio 9R59D ...


A good training ground, as it also suffered from considerable drift.

In the late 60s, an SWL lived a couple of doors from me, and he had a
9R59D. I spent quite some time rebuilding a lot of the VFO - better
capacitors, stouter wiring and, of course, I also fitted the 'optional'
neon stabiliser. It appeared to be a lot better. A few weeks later I asked
him how he was getting on with it - only to find that he had sold it!
