[Elecraft] K2-no power output

[Don Wilhelm]

Gary,

This problem has nothing to do directly with the installation of the KDSP2.
Think of whatever else you may have accidently touched - the KAT2 cables are
a relevant example.

Remove the KAT2 and feed the K2 directly into a 50 ohm dummy load - when you
press TUNE you should see the output power displayed (and it will be
accurate if you have a good 50 ohm dummy load).  That will tell you if the
K2 is capable of producing the required power output.

If you do see the proper power output with the ATU disconnected, look for
the problem with the ATU.  Check your K2 to KAT2 coaxial cable carefully to
be certain the pins are properly seated and the wires for the coax are not
broken at either end - sometimes they will break with a bit of flexing if
they are not properly soldered.

If you get no output with the ATU disconnected, then prepare yourself for
the Transmit Signal Tracing that is detailed in the Troubleshooting section
of the manual.  You will need the RF Probe assembled (or an oscilloscope
with a 10X probe) for that testing.
