[Elecraft] No power out on K1

[Cathy James]

I've nearly completed my K1, and the receiver has been calibrated and 
works extremely well.  While calibrating the receiver against my K2, I 
had a 3 foot antenna consisting of daisy-chained alligator clips 
attached to the antenna jack, and I was picking up not only the adjacent 
K2, but also RTTY signals on the band!

Sadly, the transmitter has not been so kind.  Any attempt to put the 
unit in transmit mode (by pushing WPM+ and WPM- together) resets the 
power out to 0.1 watts, which is confirmed by the external wattmeter.

All of the resistance checks on p45 have passed with the KFL1-4 removed 
and the jumper set to K1 (not KAT1).  With the KFL1-4 in place and 
14.38V at the input jack, a few of the voltage test points on p46 
indicate 0.1-0.2V above the quoted range, which is presumably a result 
of the input voltage being a little higher than recommended.  (I can 
stick a diode in the power cord if this is a real problem.)

However, J7 pin 1 shows 7.8V instead of the quoted range of 5.1-6.7V.  
What, if anything, does this indicate?  R9, D14, and D5 are all 
connected as measured by the ohm-meter.

I've looked at the schematic, and I don't understand the RF-out path 
well enough to see what the obvious culprits might be.  I have the RF 
probe that I built with the K2 plus a Tek scope.  Any suggestions before 
I dive into the transmitter signal tracing on page 6 of Appendix E?

A few pointers would be helpful before I disappear into the deep water!
