[Elecraft] Keyer goes berserk

[Madison Jones]

Thanks to everyone. The entire configuration which I described has worked
just fine ever since I acquired MORTTY last fall. I have used it in this
configuration for thousands of contacts - paddle [and usb from computer ]
into MORTTY and then into K3. The last time it all worked was for the 19z
CWT on Wednesday. However, when I was setting up for the 03z CWT without
making any changes from 19z except to change contests on N1MM+, when I set
and saved the configuration, it first acted as a straight key [which is to
say, either paddle simply gave a steady dah until I released it]. I then
rebooted N1MM+, hit F3 [tu], and at that point the K3 gave some dits and
dahs, and then would not do anything.

When I took everything apart, I suspected the MORTTY, but putting the
paddle directly into either paddle or key port on K3 produced nothing at
all - would not key K3 no way no how. Tried the MORTTY on my K/W 480, and
it worked fine. Key into 480 works fine in either the paddle or key port. I
can only conclude that since the MORTTY works fine, the cables work fine,
and the paddle works fine, that leaves only the K3 which does not work fine.

Today I rebooted the K3 and computer several times in various
configurations - N1MM, paddle with MORTTY, paddle direct to key port and
then to paddle port. The first time I did it I noticed that both red and
green lights on MORTTY lit up the first time I hit Enter on N1MM after
configuring it, but no response that I remember from K3. I thought ESM must
have disconnect itself in N1MM but it was OK. After that first attempt, I
reconfigured ports in N1MM, still no ESM, no response from K3, and no
lights on MORTTY. Nothing happens.

Has to be K3 problem, but what? Receiver works OK.
