With a tear in my eye, I read memories of old telegraph keys.
Does anyone remember a electronic key designed on two triodes and two
stabilivolts (105 and 150 V).
This key was designed by W6DPU. Very popular in the 1950s and 1960s.
The VFOs commonly used in those years used a Colpitts and Clapp type
oscillator.
With small feedback, you could get a beautiful ringing tone

Got started in 1956 as a novice using a mil surplus straight key (J-47
if I recall correctly - its around here someplace. ) Then as a general
got a Lightning Bug for Christmas and used that for 2-3 decades. Then
purchased a new one about 20 years ago and still use it, but less
since I received a plug-in keyboard keyer (with memories) from a ham
friend.
Made many terrific bug qsos over the years, some lasting 1-2-3 hours.
One with a VE3 about 7-8 years ago that ran til 3:30am. We kept
hitting on new topics that we both had in common. Used to work F5IN
into his mid 90s. And a ZS and a 9J2 in their late 80s. Bugs attract
bugs.
Im 90% cw ( no digital) these days, on 160-6m, and chasing the final 9
DX entities. now that we put 3Y0J in the log on 30m cw at 2:30 am a
few months ago.
