[Elecraft] KPA100 initial tests

[n0jrn]

Just a minor problem and looking for some advise.

All resistance checks are fine.    All voltage checks are fine except Pin 27 
on   U1

It's showing about .5   volts.

Also noted that the LED on the K2 is at the top of the scale.............

Based on the charts in the back of the KPA100  manual,   Pin 27  should go 
low when the amp is in TX.

The LED on the K2  seems to support the fact that hooking the amp up puts 
the rig in transmit.

Naturally,   I have some digging to do but was curious if there is anything 
in particular I should be looking at.

Also,    I had the power adjusted on the K2  to around 10 watts while doing 
these tests.

Is it possible for the KPA100 to sense the power level of the rig and go 
into TX.

Any thoughts??

Thanks and have a great weekend all
