SNOTEL has been doing something similar for 50 years.

Yes, MS is done with one of K1JT's protocols than encodes the elements of the

Yes, MS is done with one of K1JT's protocols than encodes the elements
of the QSO in a form that fits in a hundred msec or so, transmits it
repeatedly for a defined period (15, 30, or 60 seconds).
To try to make sense of this experiment, I immediately assumed
that Kurt wouldn't be using a hand key, but rather a device that
interfaced to the radio through the KEY jack. Obviously an
electronic switch could switch the key jack that fast, but I'm
not sure about a relay.
The other question
I've heard rumors of that but I have 38 states confirmed on two-meters (from the
depths of southern AZ), mostly on ear-copy MS. I never encountered anyone
offering or asking to use that method.
I was forced into leaving weak-signal work for a number of years following a
domestic upheaval in

Dave -
In this case the "key" is a transistor circuit and the the result is
decoded electronically.
We want to know if a K3 is capable of being used with a burst encoder. I'm
not in front of my K3 right now or I'd try it myself.

I don't see that as being realistic. Per the normal definition of a
Morse "word" being the word "paris", 300 wpm means each dit would be no
longer than 4 msec. As best I can recall, the rise and fall of the K3
keying waveform are each around 2.5 msec. I'm not at all an expert, but

I designed a memory keyer in the mid-80's. Had a ridiculous speed range.
Found out the
meteor scatter folks were buying them. They would program a memory at
normal speed,
ramp the speed up, and use it for short bursts on CW during a meteor
operation. Receiver would
record it on tape, slow it down
Kurt -
300 wpm is so far beyond any speed I am aware of a human copying that I
never gave that issue any thought... and few folks I know can send good CW
above 40 ish wpm with a hand key, so I doubt if many folks have given that
any thought. I will be interested to see what answers you get...
Greetings list!
I searched the archives and other sources, but haven't found an answer, so
I'll try here.
I'm looking to find the maximum cw speed on my K3 (with new oscillators,
serial 8xxx)
when using a manual cw key plugged into the KEY jack on the back of the
radio.
I don't mean the internal
