Perhaps a bug would more closely match your sending preferences. I
abandoned my keyer when I finally acquired a bug that I thought had a good
feel. I picked up a basket case Vibroplex original at Dayton one year,
repaired the damage (it had apparently been dropped), replaced the broken
bakelite finger pieces and cleaned it up. It turned out to be velvet
smooth, with negligible contact bounce.
My previous bugs all sucked. My first one was a Lionel J-36 WW2 surplus. I
had to weight the thing down and file on the dit spring to make it send at
less than 35 wpm, and no matter what I did to correct the problem, the
contact bounce was so bad that my characters sounded mushy. Later, I picked
up a 1947 vintage Vibroplex Original, but it wasn't much better. It felt
stiff, and no matter what I tried, I couldn't get rid of the contact bounce
on that one, eicher. I picked up my good one simply because I thought it
might be able to restore it and being somewhat of an antique, it would make
a good collector's item. It is a 1929-era classic Vibroplex with the
japanned base decorated with a gold stripe. Once I repaired the bent parts
and replaced what was broken, I was impressed with its smoothness. My other
bugs and my Bencher paddles have been collecting dust on the shelf ever
since. I never knew it was possible for a bug ot work so flawlessly.
That bug had most likely been used and abused for decades in commercial
landline service. What was left of the original bakelite finger pieces were
so well worn that they were actually eroded from use. There is quite a bit
of slop between the pivot and armature, but that doesn't seem to hamper its
functioning - perhaps that's what gives it its smooth, well broken-in feel.
I never could completely master sending with iambic paddles. I could work
the keyer from below 10 wpm to upwards around 30 wpm, but regardless of
speed, I would start out doing very well, but after a few minutes of
sending I would start making errors. After a transmission or two I would
have to correct what seemed like every other letter - a real pain for me and
the person at the other end of the QSO. I never had any problem switching
between the bug and iambic keyer. In fact, I could change over in the
middle of a word without getting the attention of the listener. But I never
could gain complete control of the iambic keyer and not make excessive
errors while sending, and I always found that frustrating.
The best electronic keyer paddles I ever laid my hands on was at Dayton
another year. I tried out a March magnetic paddle. It had the firm, solid
feel of a straight key. I figured out the reason: the magnets in those
keys are set up to repel each other, rather than to attract, as is the case
in most other magnetic paddles. With repulsion, the magnetic force
increases as the contacts approach each other, much like a real mechanical
spring. With the magnets set up to attract each other, they move farther
apart when the paddles are squeezed together, and the magnetic force
decreases. This gives the paddle a light, flimsy feel.
But I was already so happy with my old Vibroplex, that I didn't feel like
forking over the $250 he was asking for a set of March paddles.
As far as increasing copying speed, I never made any conscious effort to do
so, once I had passed the 13 wpm code test. I just had CW QSO's fairly
regularly, but not even 50% of my operating time. Most of my operating
since 1959 has always been AM phone. But I somehow managed to pass the 20
wpm Extra exam on an impulse, without practising to bone up on my code
copying, when I happened to be at the FCC's quarterly examination point to
take my First Class commercial Radiotelephone exam, and made an on-the-spot
decision to go ahead and try for the Extra while I was already there.
If you are regularly working CW and enjoying it, the increase in copying
speed will come automatically and you won't even realise it.
