The fastest I ever got was near 60 wpm. I was clocked by a puter
sending at 58 wpm one time. That was back in the later 80's.
I couldn't go much faster than that because I used an electronic
keyer and bencher paddle to send, and not a keyboard like some did.
60 wpm was about as fast as I could send with that rig. Any faster,
and I'd get too sloppy. So around 60 wpm ended up being my brick
wall. Due to a lack of operating, I'm getting a little slower every year.
I'd probably be lucky to do 25 wpm now..

Those old boatanchors in the pix above bring back some memories..
I hadn't seen that model Heathkit rcvr in a long time. I ran some pretty
old stuff when I started. At one time I ran an old Hammarlund HQ110
and a Viking Valiant, but they have been long swapped off.
I do still have some old Drake gear. I have a 2C and 2CQ, and also a
4 line twins. I have an R4 and R4C, and a T4XB transmitter.
Also still have a TS-830 and VFO-230. But I use that little Icom more
than anything these days.. :/ It does it all in one dinky box.
I actually built my first CW transmitter for 40m when I was in the
8th grade around 1972 or so. But I got lazy and put off getting the
ticket until later.
I built it from a design in the 1949 ARRL handbook.. Used an old
Navy chassis. Used a 6V6. Note the advanced scotch tape coil form
design. lol..
The receiver was that portable, and I used the white AM radio behind
it as the BFO.. I used that for a while after I did get my novice
with the HQ 110 as the rcvr.
I remember I had two xtals.. 7106 and 7119..
