[Elecraft] Hi Current message ... all the time...

[RK]

Hi,

In the final steps of building my K2 I have run into a problem...perhaps =
someone has some good sugggestions...

On all bands, on Tx, I am getting the Hi Current display. The setting in =
the menu is 3 Amps, so it's not there the fault lies.
Besides this, when I remove jumper W1, the K2 does Tx fine on all bands, =
but when the Tx-Rx switching system via Q2 is reconnected I get the Hi =
Curr message.

I have checked all components, all toroid windings etc. etc. Q2, D1-D5, =
T1-T4 etc. etc. are correctly positioned. Can't see any dry solderings, =
short-circuits etc.

 Also, DCV measurements in the tables are OK, with these exceptions:

U1 pin 9 has 0.5 DVC (listed as 0.2)
U1 pin 10 also has 0.5 DCV (listed as 0.15)
U4 pin 7 has 5 DCV (listed as 0)
U5 pin 2 has 0 DVC (listed as 5)

The Tx measurements taken when W1 is open - otherwise it would have had =
a melt-down.

Anyone know what's up?
