The J-37 I bought (surplus) came in it's original cardboard box and was mounted
on a leg clip...The operator would snap it on his thigh and send
that-a-way...It was manufactured by Winslow Electronics...Neither of my J-38's,
mounted on black bakelite plates, bears a manufacture's name...
I am building a K2.
It was originally Rev 1 but now has the Rev 2 boards
I am following the Rev E manual.
The Rev E manual says that D10 should be a 95SQ015 ultra-low-drop shottky 5A
diode
but I cant find one of those. Instead I have 2 SB530 Shottky diodes like the
one that goes into D12.
Q:
I want to thank those that responded to my question
on the J-37/J-44 E.F. Johnson Key the history of it
makes it about 62 years old. Considering the fact I
used it as a tech class ham in '77 and I'm putting it
back on the air again after 20+ years of non-cw
operating makes it even more special. I

A J-37 on the leg clip becomes a J-45 under the old Army Signal Corps naming

Although not a big contester as a rule, last weekend I had a lot of fun

Good question, Andy. I started to investigate this last night actually and
found the keying using the interface from the computer RS232 port to the KIO2

If you are running a Windows NT based OS (NT/2000/XP),
the cw timing problem is an artifact of Windows. I
believe K2Remote gets around this by using the built

Unfortunately none of the logging programs I've tried
support this feature.

That's silly! Modern computers are WAY more capable than that. Someone

Guys, Jim is correct. A PC running windows and most contest/ham
programs will key the K2 (or any other CW-capable rig) very nicely. But
only if the computer is fast enough to handle all its tasks AND the CW
functions as well. Don't expect an old slow Pentium 3 system to handle
it very

Thanks to everyone who spoke on this topic. I really appreciate the help.
Looks like I'll either have to break down and build the SSB module for the
PTT or the WinKey looks like an interesting alternative with lots of
flexibility. Much to mull over! Thanks everyone.

Why would you need to do that? Just make up a simple transistor switch
from one of the comm ports and hook it to the CW key input jack of the K2.
Writelog will work just fine running the K2 in break in mode.. Or even full
break in mode. Drive a reed relay with the comm port if you need lower

My thoughts exactly - even though Writelog provides a PTT output, it will
withhold keying until after PTT time - and the K2 will not care - it waits
until it sees a closure on the key contacts to transmit anyway.
The K2 PTT input is only a PTT input when in SSB mode - it is the DOT input

Actually, if you had a C64 your timing problems would be solved. I wrote a
