[Elecraft] 6 - 10 preamp not working

[Larry Snyder]

I ordered the 6-10 preamp and it doesn't appear to work.

 

I used the DB-15 Y cable from the radio - one end connected to the DB-15 to
the preamp and the other with the supplied mini gender changer (which
doesn't have the black dot on it according to the documentation)  connected
to the KAT500 which then connected to the KPA500.

 

The power for the preamp is connected to the RCA which is connected to the
RCA splitter connected to the back of the K3.  The other end of the RCA
connects to the KAT500.

 

I went to 10 meters on the K3.

 

I set CONFIG->DIGIOUT I to ON.

 

I am on the 10 meter repeater in NY on 29.620 - with the tone.   It keys up
fine and I can hear the repeater without the RX ANT selected.

 

I key the repeater

 

I hear the repeater


I hit RX ANT and I hear only static.  I key the repeater and hear static
only.  Release the RX ANT and I hear the repeater.


on the P3 The waveform at the bottom is -125 to -130 with the RX ANT not
enabled.  When I hit RX ANT the whole waveform drops to -140.

 

The 6-10 preamp will click with I unplug the 12 volts (so I know it is
getting 12 volts).

 

Any ideas??
